Studies in the liverwort genus Fossombronia (Metzgeriales) from southern Africa. 11. F. zuurbergensis, a new species from Eastern Cape and new records for the area
Authors: Perold S. M.
Published: July 2015

Fossombronia zuurbergensis Perold, sp. nov. from Eastern Cape is described. It is distinguished by having leaves and pseudoperianths with markedly dentate margins; the spore ornamentation on the distal face consists of ridges which can be quite variable, although, at least some of them run parallel to each other in straight or curved, short or long ridges, others occurring at right angles to the former. New records for F. capensis var. capensis and F. crispa are reported for Eastern Cape.

Authors: Perold S. M.
Published: July 2015

Riccia sibayenii Perold is a new species, recently collected in Mpumalanga, near Sibayeni and has been named for this town, which is close to the Mozambique border and is in the summer rainfall area.  R. sibayenii is distinguished by lime- green, medium-sized to quite large thalli with a chlorophyllose dorsal epidermis, air pores that soon enlarge and lead into mostly 6-sided air chambers below; ventrally with a thin median layer of storage tissue; ventral scales absent and the rhizoids all smooth. The spores are winged and polar, the distal face completely or incompletely reticulate and the proxi­mal face ornamented with fine to coarse, sometimes spinose granules.

The genus Buglossoides (Boraginaceae) in southern Africa
Authors: Retief E. , Van Wyk A. E.
Published: July 2015

The genus Buglossoides Moench, a member of the family Boraginaceae. subfamily Boraginoideae. tribe Lithospermeae. is revised tor the Flora of southern Africa (FSA) region.  Buglossoides comprises about seven species of annual, biennial or perennial herbs and subshrubs native to Asia, southern Europe and northern Africa.  B. arvensis (L.) I.M Johnst.. a naturalized weed in many parts of the world, is the only member of the genus represented in the flora of southern Africa, presumably introduced with imported cereal seed. Although the similar polyaperturate pollen grains of  Buglossoides and Lithospermum support the view that they are congeneric, they are retained as separate entities here. Diagnostic characters, a full description, various illustrations and a distribution map of B. arvensis in southern Africa are given.

The taxonomic significance of trichome type and distribution in Melolobium (Fabaceae)
Authors: Moteetee A. , Van Wyk B-E. , Tilney P. M.
Published: July 2015

All species of Melolobium Eckl. Zeyh. were examined for epidermal features and particularly the glands which are a distinctive feature amongst the southern African Genisteae. For comparative purposes, three species of Argxrolobium Eckl. Zeyh.. all  five species of Dichilus DC. and five species of Polhillia C.H.Stirt. were also examined for trichome type and distribution. Three trichome types are recognized in Melolobium. Trichome type and distribution provide an important insight into taxonomic relations at species level in Melolobium and sometimes even allow a distinction between regional forms. The distribution of glands (sessile and stalked) is of considerable diagnostic value in identifying  species  of Melolobium. A key to all the species of the genus based mainly on type and distribution of trichomes. is presented.

A study of ovule-to-seed development in Ceratiosicyos (Achariaceae) and the systematic position of the genus
Authors: Steyn E. M. A. , Van Wyk A. E. , Smith G. F.
Published: July 2015

A light microscope study of developing ovules and seeds of Ceratiosicyos laevis (Thunb.) A.Meeuse was undertaken to aug­ment an investigation of ovule and seed structure in Achariaceae. a tri-generic family comprising three species of herbaceous perennials endemic to southern Africa. Tests for myrmecochory suggest that seed of Ceratiosicyos Nees is not dispersed by ants like those of Acharia Thunb. and Guthriea Bolus. Structural differences include the absence of a raphal ridge and imbibition lidand the presence of long funicles and medium-sized embryos in Ceratiosicyos.

Authors: Siebert S. J. , Van Wyk A. E. , Bredenkamp G. J. , Du Plessis F.
Published: July 2015

A hierarchical classification, description, and ecological and floristic interpretations are presented on the vegetation types of the grasslands and wetlands of the Sekhukhuneland Centre of Plant Endemism. Relevés were compiled in 74 stratified random plots. A TWINSPAN classification, refined by Braun-Blanquet procedures, revealed eight associations. 11 subassociations and four variants. Many new syntaxa are described and ecologically interpreted. For each syntaxon. the species richness, endemism and conservation status was determined. The floristic and habitat information, proposed classification, general description and vegetation key are provided to aid future identification of conservation areas, land use planning and further research. An ordination (DECORANA). based on floristic data, confirmed the relationships that exist between plant communities and associated habitats and environmental gradients. Much of the plant community diversity and distribution can be ascribed to a heterogeneous environment, predominantly determined by soil moisture.
Studies in the genus Machairopliyllum (Mesembryanthemaceae), with notes on some related genera
Authors: Kurzweil H. , Chesselet P.
Published: July 2015

Machairophyllum Schwantes is a small genus of the family Mesembry anthemaceae. confined to the southern part of central South Africa from the Little Karoo at Barrydale in the west to the Zuurberg near Kirkwood in the east. Machairo­phyllum is unusual in the Mesembryanthemaceae-Ruschioideae in that fynbos and renosterveld are the preferred habitats. The morphology, anatomy as well as the pollen, seed and leaf epidermis ultrastructure of the genus were examined. The taxonomy of Machairophyllum is revised on the basis of data presented. Of the ten names originally described, only four are upheld. M. alhidum (L.) Schwantes, M. stayneri L.Bolus. M. bijliae (N.E.Br.) L.Bolus and M. brevifolium L.Bolus. All four species are very similar in their vegetative habit, and differ mainly in inflorescence and flower characters. Several presumably related genera. Bijlia N.E.Br..  Carruanthus (Schwantes) Schwantes and  Cerochlamys N.E.Br.. are briefly discussed.
Taxonomy of the genus Passerina (Thymelaeaceae)
Authors: Bredenkamp C. L. , Van Wyk A. E.
Published: July 2015

Passerina L. is mainly a southern African genus, comprising 20 species and four subspecies. A few species occur along the Great Escarpment, two extend into Zimbabwe and Mozambique, but most are concentrated in the Cape Floristic Region. Palynological. macromorphological and anatomical evidence was used in the delimitation of the genus and its infrageneric taxa. A cladistic study supports Passerina as a monophyletic genus. A genus treatment, key to species and a full species treatment are given. Each species treatment includes a taxonomic diagnosis, description and notes on taxonomy, etymology, economic value and distribution. Illustrations of representative species are provided and distribution maps are included for each species.  P. esterhuyseniae Bredenk. A.E.van Wyk is newly described. A list of excluded species names highlights the previous cosmopolitan taxonomic interpretation of Passerina. as many names are now in synony my under other genera of the Thymelaeaceae.

A comparison of Mopaneveld vegetation in South Africa, Namibia and Zimbabwe
Authors: Siebert F. , Bredenkamp G. J. , Siebert S. J.
Published: July 2015

Data from fifteen phytosociological studies were merged and classified to describe and compare the vegetation of geo­graphically separated and climatically different Mopanev eld types in South Africa. Namibia and Zimbabw e. Seven v egetation types and ten major plant communities were identified using TW INSPAN. Vegetation types were separated according to geo­graphical regions. There were significant floristic affinities even though there w ere geological and climatic differences between the regions. Plant communities were described according to vegetation structure, habitat and floristic composition. Although environmental data were not adequate for a detailed ordination. DECORANA reflected the distribution of vegetation types and major plant communities along environmental gradients. Limitations of large phytosociological syntheses were also addressed. Species richness (alpha diversity) was calculated for each geographical region. The Musina (Messina) region north of the Soutpansberg. South Africa, has the highest species richness, and Kaokoland. Namibia, the lowest Due to irregular annual rainfall patterns in semi-arid Mopaneveld, it is suggested that variance in species richness is associated with temporal vegeta­tion states induced by rainfall events. Species richness of Mopaneveld was further compared w ith other sav anna types.

Embryology and systematic relationships of Kiggelaria (Flacourtiaceae)
Authors: Steyn E. M. A. , Van Wyk A. E. , Smith G. F.
Published: July 2015

Kiggelaria L. is endemic to Africa and the only representative of tribe Pangieae (Flacourtiaceae) on the continent. Molecular genetics, phytochemistry and host-parasite relationships have indicated a relationship between this woody, pantropical tribe of Flacourtiaceae and a small, trigeneric family of herbaceous, southern African endemics, the Achariaceae. In the present study, ovule and seed structure in Kiggelaria were investigated and compared with relevant data recently reported for Achariaceae. Support for an alliance with Achariaceae were found in the presence of anatropous, bitegmic. sessile ovules with zigzag micropyles. deep-lying embryo sacs covered by an epistase in the ovule and seed, endotestal-exotegmic seed coat layers, suspensorless embryos and sarcotestal seed with a prominent, plate-like hypostase. Unlike Achariaceae.  Kiggelaria seeds do not have chalazal seed lids, pronounced raphal ridges, a fringe layer, or stomata in the outer epidermis of the sarcotesta. Structural dissimilarities in seeds of omithochorous  Kiggelaria and myrmeco- chorous Achariaceae were regarded as adaptations linked to adifferent strategies for seed germination and dispersal.

Functional and taxonomic significance of seed structure in Salix mucronata (Salicaceae)
Authors: Steyn E. M. A. , Smith G. F. , Van Wyk A. E.
Published: July 2015

The polymorphic African willow, Salix mucronata Thunb., is a widely distributed African tree and a riparian rheophyte. Ovule-to-seed development is reported for Salix mucronata subsp. woodii (Seemen) Immelman. Contrary to some existing reports, the tuft of silky hairs enveloping the seed in Salix is derived from the funicle and not the placenta. The micromor- phological structure of the hilar aril and funicular-placental and arillate hairs is described and illustrated for the first time.Willow seeds are primarily wind-dispersed, but have additional characters, such as a hydrophobic seed coat and an unwet- table, hairy, hilar aril as specific adaptations for distribution by water, perhaps even chance dispersal by animal visitors to the riverine habitat. Seed adaptations linked to different dispersal strategies may account for seemingly marked differences in ovule/seed structure between Salicaceae S.  str. and related, mainly zoochorous flacourtiaceous taxa. recently classified with the former in a more inclusively circumscribed Salicaeae s.l.

Three cryptic new species of Aristea (Iridaceae) from southern Africa
Authors: Goldblatt P. , Dold A. P. , Manning J. C.
Published: July 2015

Field work in southern Africa over the past several years has resulted in the discovery of three new species of the sub- Saharan African and Madagascan genus Aristea Aiton, which now comprises some 53 species. Aristea has a pronounced centre in southern Africa and a centre of diversity in the winter rainfall zone of the subcontinent, where all three new species occur, one extending eastward into the adjacent southern edge of the summer rainfall zone. All three novelties have been collected in the past but were confused with related species. A elliptica (subgenus Eucapsulares), confused in the past with A. pusilla (Thunb.) Ker Gawl., has a more robust habit, usually with 4 or 5 flower clusters per flowering stem, pale blue flowers, smooth ellipsoid seeds with flattened surface cells, and pollen shed as monads, whereas A. pusilla usually has 1-3 flower clusters per flowering stem, dark blue flowers, pollen shed as tetrads, and globose seeds with faint foveate sculpturing and colliculate surface cells. A. nana (also subgenus  Eucapsulares), known from few collections, and also confused with A. pusilla or A. anceps Eckl. ex Klatt. has the unbranched and leafless flowering stem of the latter but has large green floral spathes, flowers borne on long pedicels, and lacks a leaf subtending the single terminal flower cluster in contrast to nearly sessile flowers in A. pusilla and A. anceps, and in the latter, dry, rusty spathes. A. cistiflora (subgenus Pseudaristea) closely resembles A. teretifoha Goldblatt J.C.Manning but has linear to narrowly sword-shaped leaves and ± secund flowers with the outer tepals only slightly smaller than the inner and with small, dark brown markings at the bases of all the tepals. In contrast, A. teretifolia has narrower, sometimes terete leaves and flowers held upright with the outer tepals notice-ably smaller than the inner and bearing dark markings covering the lower half, whereas the inner tepals are unmarked.

The character states pertinent to the indumentum of Lobostemon Lehm. leaves are tabulated and discussed. Lobostemon possesses similar trichome and indumentum types as described for Echium L.. with the exception of the ‘Alpine’ indumentum type. Due to the environmentally induced variation, the leaf indumentum characters of Lobostemon are viewed to be of limited phylogenetic value, although they do diagnose a number of taxa.
Eremiolirion, a new genus of southern African Tecophilaeaceae, and taxonomic notes on Cyanella alba
Authors: Manning J. C. , Forest F. , Mannheimer C. A.
Published: July 2015

The generic affiliation of Cyanella amboensis Schinz has been uncertain since the species was excluded from the genus Cyanella L. in 1991. The species has two leaves, a divaricately branching inflorescence, ebracteolate pedicels, and acti- nomorphic flowers with monomorphic anthers. It is endemic to the western parts of central and northern Namibia. Other species of Cyanella have several leaves, racemose inflorescences, bracteolate pedicels, zygomorphic flowers with dimor­phic anthers, and are endemic or near-endemic to the winter rainfall region in southwestern South Africa and southern Namibia. These differences are consistent with the recognition of the species as a distinct genus within the family. Phylogenetic analysis of plastid DNA sequences indicates that C.  amboensis Schinz is sister to the other species of Cyanella, a relationship that also supports its independent generic status. The monotvpic genus Eremiolirion is according­ly erected to accommodate the species. Minor differences in flower colour and vegetative morphology in Cyanella alba L.f. are shown to correlate with the three disjunct groups of populations in which the species occurs, and these populations are recognized at the level of subspecies.

Floristic composition of gold and uranium tailings dams, and adja­cent polluted areas, on South Africa’s deep-level mines
Authors: Weiersbye I. M. , Witkowski E. T. F. , Reichardt M.
Published: July 2015

Gold and uranium tailings (‘slimes’) dams and the adjacent polluted soils in the deep-level mining regions of South Africa (Carletonville, Klerksdorp and Welkom) were surveyed for the frequency of occurrence of naturally colonizing, actively introduced and persisting plant species. Fifty-six tailings dams with a combined area of 5864 ha. and a similar area o f tail- ings-polluted soils, were surveyed between July 1996 and March 1997. During the survey, 376 plant species and subspecies were recorded from the dams and adjacent polluted soils, with an additional  8 6  records obtained between 1998 and 2003 (i.e. a total of 462 taxa: species and infraspecific species). Overall, the most commonly represented families were the Poaceae (107 species and subspecies), Asteraceae (81). Fabaceae (55) and Anacardiaceae (16). with other families represented by just one to 14 species. Only 60 species were common to all three regions, and of these 24 had been introduced during rehabilitation attempts. Most of the species found on tailings were persisters or natural colonizers (53-88%, depending on substrate), with the vast majority being indigenous and perennial taxa (76% and 85% respectively), with semi-woody to woody growth forms (6 6% being resprouters, forbs, shrubs and trees). Less than 4% of the naturally-colonizing taxa found during the survey had also been introduced by vegetation practitioners. The majority of introduced plants were alien herbaceous taxa. The number and frequency of annuals was only high on recently vegetated sites, whereas annuals were rarely present on old-vegetated and never-vegetated dams. This list includes a wide range of indigenous plant species that may be suitable for phytoremediation of tailings dams and polluted soils due to their apparent tolerance of acid mine drainage and salinity.
New species of Iridaceae from the Hantam-Roggeveld Centre of Endemism, and the Bokkeveld, Northern Cape, South Africa
Authors: Manning J. C. , Goldblatt P.
Published: July 2015

Three new species of Iridaceae are described from the Bokkeveld and Roggeveld Escarpments.  Ixia amethystina. a member of section Dichone, is endemic to the edge of the Roggeveld Escarpment. It shares an unusual, inclined spike that is nodding in bud with  I. trifolia but is distinguished by its blackish purple (not yellow) anthers, narrower leaves 1.5-2.0 mm wide, medium-textured corm tunics that form a distinct neck at the base of the stem, and short style branches 2.0-2.5 mm long.Moraea marginata. another Roggeveld endemic, is a member of section Polvanthes and florally similar to M. fistulosa and M. monticola but differs in its linear, channelled leaves 5-7 mm wide, with unusual, thickened margins. Romulea singularis. from the edge of the Kobee River Valley in the Bokkeveld Mountains, is a member of section  Ciliatae. It is unique in the genus in its narrowly funnel-shaped, mauve to purple flowers with slender perianth tube 10-11 mm long, and unusually long filaments, 8-9 mm long, inserted in the lower half of the tube.

Phytogeography of Passerina (Thymelaeaceae)
Authors: Bredenkamp C. L. , Van Wyk A. E.
Published: July 2015

Passerina L. comprises 20 species and four subspecies of microphyllous. wind-pollinated shrubs. Once considered cos­mopolitan, the genus as currently defined, is endemic to southern Africa. Endemism within the genus is highest in the Cape Floristic Region (CFR), where all members show morphological and anatomical adaptations to the winter rainfall and dry warm summers of the Mediterranean or semi-Mediterranean climate of the region. The Western Cape is the centre of diversity for Passerina, from where certain species extend to the west, north and east. The outlier populations of Passerina montana Thoday on the interior plateau of South Africa and Zimbabwe, as well as the Auas Moutains in Namibia, most probably origi­nated in the CFR and formed part of a previously wider northern temperate Afromontane grassland-dominated vegetation during the Quartemary, of which relicts remained in the high mountain areas. P. burchellii Thoday and P. paludosa Thoday have the most restricted distribution and are regarded as Vulnerable. All other species are either widespread or under no im­mediate threat.

The handling of controversial Proposal 1584 to conserve the name Acacia with a conserved type for the Australian acacias during the Nomenclature Section meeting at the 17th International Botanical Congress (Vienna) in 2005 is reviewed. Through a simple majority vote, this Section adopted rules requiring a 60% majority of votes to approve any proposal to modify the International Code of Botanical Nomenclature and a simple majority to approve all other motions; motions not receiving the required majority were to be rejected. However, for the motion addressing Proposal 1584, 45.1% voted to conserve the type of the name Acacia for Australian acacias, and 54.9% voted to retain the current African type for the name Acacia. Even though this motion failed to get a 60% majority either way as required by the Section’s own rules, Section officials have concluded that the name Acacia is to be conserved for Australian acacias. Treating a motion as approved, even though it received only minority support, also violates the fundamental principle of standard parliamentary procedure—the right of the majority to approve proposals. For Acacia to be formally conserved, the Nomenclature Section needed to approve a motion addressing Proposal 1584 with a majority vote, and this never happened in Vienna. Recommendations are made on how this process might be improved.

Published: July 2015

Balanites maughamii Sprague (Balanitaceae) is a woodland tree used and harvested for bark products in the traditional medicine trade o f South Africa. The tree has a distinctively fluted and buttressed stem, especially in mature individuals. This short communication quantifies the relationship between two diameter measurements D1 and D2 that respectively exclude and include the bark surface contained in the convolutions of the flutes at five height intervals up the stem to 2 m. Regressions show D1 to be an accurate predictor of D2 (r^ =0.97-0.99) over a range of tree sizes, hence obviating the necessity to measure both D1 and D2. The circumference and bark surface area on the stem was determined to estimate the quantity of bark that can potentially be harvested. At least 69% of the stem circumference and bark surface area was estimated to be contained within the convolutions of the flutes.

Two new species of Babiana (Iridaceae: Crocoideae) from western South Africa, new names for B. longiflora and B. thunbergii, and com­ments on the original publication of the genus
Authors: Goldblatt P. , Manning J. C. , Gereau R.
Published: July 2015

Babiana symmetrantha and B. virescens are two new species of section Teretifolieae of this southern African genus, now comprising 90 species. Babiana symmetrantha blooms in August and early September and is restricted to the summit of the Langberg which lies along the border of Namaqualand and the western Karoo near Loeriesfontein. One of only three species of the section with radially symmetric flowers, it is acaulescent and has linear, almost plane leaves covered with long hairs, a perianth tube 45-60(-75) mm long, and subequal, spreading tepals. Babiana virescens blooms in early winter, in May and June, and occurs in seasonally moist open ground on gentle slopes and valley bottoms in southern Namaqualand between Nuwerus and Bitterfontein. It is distinguished by the slightly misted, oblong leaves with thickened, pale margins, and the glabrous cataphvlls and leaf sheaths. The stem, which may be produced up to 100 mm above the ground, is simpleor has a single short branch and the spikes bear 2-6 greenish flowers, the tepals of which are unusually narrow and longer than the perianth tube. We also propose a new name. B tubaeformis.  for the homonym B. longiflora and provide a new combination  B.  hirsuta based on the 1783 name Antholyza hirsuta Lam., which replaces B thunbergii Ker Gawl. (1804). Lastly, we present an argument that Babiana is correctly attributed to Ker Gawler alone and that its protologue dates from 1802 contrary to some current authorities.

Three new species of Gladiolus (Iridaceae) from South Africa, a major range extension for G. rubellus and taxonomic notes for the genus in southern and tropical Africa
Authors: Manning J. C. , Goldblatt P.
Published: July 2015

Three new species of Gladiolus L. are described from South Africa.  G. dolichosiphon is the second known member of series Blandus from the mountains of the Little Karoo in Western Cape, and is distinguished from other members of the long tubed, pink-flowered G. carneus complex by its 5 or 6 linear leaves, creamy pink to salmon flowers with a tube 30-50 mm long and longer than the dorsal tepal, and its late summer flowering. G. karooicus from the Klein Roggeveld and the northern foothills of the Witteberg, is a spring-flowering species allied to G. permeabilis but has bright, canary-yellow flowers with the lower part of the lower tepals involute and conspicuously auriculate.  G. reginae is an edaphic endemic of the Sekhuk- huneland Centre of Floristic Endemism in Mpumalanga, and flowers in autumn. It is evidently a glabrous member of section Densiflorus series Scabridus, distinguished by its long-tubed flowers, streaked with red on the lower tepals and blotched with red in the throat. Anomalously, however, it has the tubular inner bracts and large capsules diagnostic of section Ophiolyza series Oppositiflorus. A re-examination of the morphology suggests that series Scabridus is better placed in section Ophiolyza and a slightly revised classification of Gladiolus in southern Africa is proposed. We also propose the replacement name G. sulculatus for the Tanzanian species, G. sulcatus Goldblatt, a later homonym of G. sulcatus Lam. Finally, a recent sighting of what appears to be G. rubellus from northern Namibia constitutes the first record of this species in the country and a major range extension from its previous known occurrence in southeastern Botswana.
Albucacrispa and A. grandis (Hyacinthaceae: Omithogaloideae), two new species of subgenus Albuca, the rediscovery of A. albucoides (sub­ genus Osmyne), and the identity of A. reflexa
Authors: Manning J. C. , Goldblatt P.
Published: July 2015

Albuca crispa is a new species of section Falconera series Trianthera with crispulate leaves from the Great Karoo, known  at least since 1947 but overlooked until now. A second new species. A grandis. from the southwestern Cape was previously included in  A. fragrans Jacq. (section  Falconera series  Falconera). It is a robust species that flowers in winter and early spring and the styles are rugulose with ± isodiametric epidermal cells, unlike typical  A. fragrans which is a more slender species flowering in early summer and with derived, smooth styles with fusiform epidermal cells. The recent discovery of a flowering population matching the type of A. albucoides (Aiton) J.C.Manning Goldblatt (subgenus Osmyne) allows for a full description and illustration of this poorly know n and taxonomically neglected species that has often been included in A. suaveolens (Jacq.) J.C.Manning Goldblatt. Lastly, examination of the type  of A. reflexa Krause Dinter from Namibia shows it to be conspecific w ith Drimia indica (Roxb.) Jessop.

A generic classification of the Restioneae (Restionaceae), southern Africa
Authors: Linder H. P. , Hardy C. R.
Published: July 2015

We propose a new generic classification of the African Restionaceae, tribe Restioneae (subfamily Restionoideae), based on the phylogeny and on extensive morphological data. The phylogeny is based on both plastid sequence data and morphological data. We delimit the genera to be monophyletic, to minimize the nomenclatural changes, and to maximize the ability to diagnose the genera. We recognize eight genera, one of which with nine subgenera, in the tribe. Of the currently accepted genera, only three need changes. We provide descriptions for all genera and subgenera, and include a key to them. In this paper we erect one new genus, Soroveta. redelimit Platycaulos and Restio, and reduce Calopsis and Ischyrolepis to synonomy under Restio. We list the species which we recognize under each genus, make 37 new combinations, propose eight new names, and also describe eight new species that belong in these genera.
New taxa of Babiana (Iridaceae: Crocoideae) from coastal Western Cape, South Africa
Authors: Goldblatt P. , Manning J. C.
Published: July 2015

Discovery of populations south of Elandshaai of a small-flowered plant closely allied to Babiana ringens led to a critical re-evaluation of this sunbird-pollinated Western Cape species. We conclude that these populations represent a new species, B. avicularis, recognized by long, arching, subterete leaves, and flowers with the lower part of the perianth tube sigmoid and ± 4 mm long, a dorsal tepal 15-18 mm long, pale green lower tepals directed forward, and a style dividing below the bases of the anthers. In addition, the southern coastal populations of B. ringens merit recognition as a separate subsp. australis, recognized by the smaller flower, filaments not reaching the apex of the dorsal tepal and the style dividing at or below the bases of the anthers. Field work along the Western Cape coast also resulted in the discovery of a new species, B. teretifolia, allied to the distinctive B. brachystachys but differing from that species in the linear, spreading, twisted tepals, filaments 12 mm long, white anthers 5.5-6.0 mm long, and the style dividing opposite the anther tips, with branches ± 5 mm long and notched at the tips.

Floristic composition of wetlands of the South African section of the Maloti-Drakensberg Transfrontier Park
Authors: Sieben E. J. J. , Kotze D. C. , Morris C. D.
Published: July 2015

A survey was conducted on the wetlands in the South African section of the Maloti-Drakensberg Transfrontier Park (MDTP), along altitudinal gradients from the foothills to the summit plateau in six different catchments. Environmental indices of soil wetness, texture and organic contents of the soil were determined to relate wetland community types to their environment. Thirty-six plant communities were recognized with a total of 56 subcommunities. These communities fall into five different categories: I, the high-altitude fens and seepages are a loose grouping of distinct vegetation types from the summit plateau and just below; 2, hygrophilous grasslands are the marginal areas of the wetlands that are temporarily wet and dominated by grasses, most of which are common outside wetlands; 3, shrubby wetlands are in most cases hygrophilous grasslands that have been invaded by shrubby species due to disturbance; 4, mixed sedgelands are the largest grouping and are dominated by sedges or grass species that are specifically adapted to wet conditions; 5, low-altitude sedge and reedlands are vegetation types that occur only marginally in the Maloti-Drakensberg area and are dominated by Carex acutiformis and Phragmites australis.The most important variables that explain the variation in wetland egetation are altitude and soil wetness.
Wetland craft plants in KwaZulu-Natal: an ecological review of har­vesting impacts and implications for sustainable utilization
Authors: Traynor C. H. , Kotze D. C. , McKean S. G.
Published: July 2015

In South Africa, wetland plants have been used for centuries and they continue to be harvested for subsistence and commercial purposes. Fibres for crafts are collected by cutting the aboveground parts. KwaZulu-Natal is one of the major basket-producing regions in southern Africa and at least twenty-two species of wetland plants are harvested for crafts. A literature review of the harvested species revealed that the impacts of cutting have only been extensively investigated for Phragmites australis (Cav.) Steud. and Juncus kraussii Hochst. The review suggested that, where plants display strong seasonal aboveground productivity patterns, cutting should take place after shoot senescence and before new shoot emergence to minimize damage to plants. Cutting in the short term could increase the density of green stems. However, in the long term in  Phragmites australis, it may deplete the rhizome reserves and reduce the density of useable (longer and thicker) culms.The opportunity for sustainable harvests was investigated by considering the geographic distribution, whether species are habitat specific or not, and local population sizes of the craft plants. Juncus kraussii is of the greatest conservation concern.Ecologically sustainable wetland plant harv esting could contribute to the wise use of wetlands, an approach promoted nationally and internationally.
Moraea intermedia and M. vuvuzela (Iridaceae-Iridoideae), two new species from western South Africa, and some nomenclatural changes and range extensions in the genus
Authors: Goldblatt P. , Manning J. C.
Published: July 2015

We describe two new species in the largely sub-Saharan genus Moraea Mill. (± 205 spp.) from its centre of diversity in the winter rainfall region of southern Africa. Moraea intermedia, from north-central Namaqualand near Springbok, is a member of the small section Tubiflorae (now eight species), remarkable in its growth habit with a long basal intemode. leaves clustered at the first aerial node, and Moraea-type stamens and style branches but subequal tepals with very short claws that clasp only the base of the filament column. Moraea vuvuzela. a member of series Galaxia of the Galaxia group of the genus (now 17 species), has deeply fringed stigma lobes, filaments free in the upper 1 mm, ± prostrate, lanceolate leaves and. remarkable for the series, dark brown to purple markings near the base of the tepal limbs. In the unusually variable M.fugax, currently with two subspecies, new collections of subsp. fugax co-occurring but on different soils with subsp.  filicaulis, cast doubt on their current treatment as members of the same species. We now favour recognition of the diminutive subsp.filicaulis as a separate species, M. filicaulis. In the M iripetala group we recommend recognition of the early blooming M. punctata, described in 1892 and later subsumed in M. iripetala but readily distinguished by the long inner  tepals broader in the midline and short, relatively broad, plane rather than channelled leaves. We also report small but significant range extensions for M. barkerae, M. macrocarpa and M. tricolor.

Bottomley’s (1948) Gasteromycetes of South Africa is still widely used for identification purposes. However, as a result of developments since 1948, the work has become outdated in many respects. Entries in the Clathraceae are here updated and briefly commented upon and a species key to the twelve southern African representatives of the family is provided.
