Studies in the southern African species of Justicia and Siphonoglossa (Acanthaceae): palynology
Authors: Immelman K. L.
Published: July 2015

The gross morphology of the pollen of all southern African species and subspecies of Justicia and  Siphonoglossa was investigated, as well as that of eight tropical African species of  Justicia. The following pollen types were found in the southern African species of Justicia:  two- or three-colporate, each with the margocolpus either entire or broken up into areolae, and two-porate areolate pollen. One tropical African species had the colpus very short, and in another tropical African species it was replaced by an extra row of areolae. All  Siphonoglossa species had two-colporate pollen with areolae and long colpi. The southern African species of Justicia could be separated from  Siphonoglossa on pollen characters, and some sections of Justicia could also be distinguished on the same basis.
Studies in the genus Riccia (Marchantiales) from southern Africa. 13. A new species, R. hantamensis, in section Pilifer and a new record for R- alatospora
Authors: Perold S. M.
Published: July 2015

Riccia hantamensis, a new species from the Hantams Mountain, District Calvinia, is described. It is clearly related to R. alatospora, but is a much larger plant. Like other species with a dorsal epithelium of free-standing cell pillars, it belongs to section Pilifer Volk.  R. alatospora, originally only known from Platklip, Stellenbosch (Volk Perold 1985), is now also recorded from Carolusberg, Hester Malan Reserve, Namaqualand.
Observations on plant usage in Xhosa and Zulu medicine
Authors: Hutchings A.
Published: July 2015

The holistic concept of Xhosa and Zulu traditional medicine and some differences from Western orthodox practice are briefly outlined. The transmission of herbal knowledge within various social groups is outlined. The background, training and some procedures followed by five of the informants are discussed. Plant characteristics that may be seen, felt, smelled or tasted are considered as possible determinants of usage. The form of plant parts accounts for some usage in the more magically orientated medicines whereas colour, texture or the production of froth may signal the presence of medicinally active components such as tannin, mucilage and saponin. The role of plants producing a milky latex is discussed. Vesicant or irritant properties are utilized in septic or inflammatory conditions. Aromatic plants are used for respiratory or digestive disorders and pungent-smelling plants are used in the treatment of catarrh and some stress-related disorders. Bitter or sour- tasting plants may be used as an aid to digestion or serve a deterrent function. Parallel usage of some related plants in African and European herbal practice indicates that appropriate usage may be widely determined by easily discerned plant characteristics. Two herbal medicinal recipes recorded by the author and a list of medicinal plants collected in Transkei are presented.
Invasive alien woody plants of Natal and the north-eastern Orange Free State
Authors: Henderson L.
Published: July 2015

The frequency and abundance of invasive alien woody plants were recorded along roadsides and at watercourse crossings in 87% (152/175) of the quarter degree squares in the study area. The survey yielded BO species of which the most prominent species (in order of prominence) in roadside and veld habitats were:  Chromolaena odoruta, Solatium mauritianum, Psidium guajava, Rubus spp., Acacia meamsu and Lantana camara The most prominent species (in order of prominence) in streambank habitats were:  Acacia dealbata, A. meamsii and  Salix babylonica.The greatest intensity of invasion was recorded in the Natal midlands and in the coastal belt of southern Natal, including the metropolitan areas of Pietermaritzburg and Durban. There was relatively little invasion in the north-eastern lowlands of Natal but the potential for expansion is great. Little invasion was recorded in the north-eastern Orange Free State except along some watercourses.

Studies in the genus Riccia (Marchantiales) from southern Africa. 15. R. hirsuta and R. tomentosa, sp. nov., two distinct species previously treated as one
Authors: Volk O. H. , Perold S. M.
Published: July 2015

The description of Riccia hirsuta (Volk Perold 1986) is emended and new illustrations of the species are provided, as the original description and illustrations were based on  two distinct, but rather similar species. Examination of newly collected material of R. hirsuta, showed it to belong to subgenus Riccia, section Pilifer (Volk 1983). Section Micantes (Volk Perold 1986) of which this was the type species, is therefore transferred to section Pilifer. R. tomentosa Volk Perold, sp. nov., described here, is at first glance somewhat similar to R. hirsuta in its habit, hence the earlier confusion in Volk Perold (1986). It also resembles R. hirsuta in its dorsal covering of long hairs and in the triangular scales apically split into cellular strands. R. tomentosa, however, differs from R. hirsuta in the spongy (not compact) construction of the thallus and in the spores permanently united in tetrads (not single). It belongs to subgenus  Thallocarpus and is the type species of the new section Pannosae.
Studies in the southern African species of Justicia and Siphonoglossa (Acanthaceae): seeds
Authors: Immelman K. L.
Published: July 2015

The seeds of all species of Justicia (except J. thymifolia (Nees) C.B. Cl.) and Siphonoglossa in the southern African region (as defined by the Flora of southern Africa) were examined with the Scanning Electron Microscope. A wide range of different seed surfaces were seen, many of which could be correlated with other characters to further reinforce grouping of species into sections. However, some species that on other characters, would be placed together, had widely differing seed testas. Gross surface morphology varied from smooth to colliculate, irregularly rugose, reticulate with the ridges variously arranged, wheel-shaped (radiate or ammonite-like), with a central ridge or with multicellular barbed scales. The seeds were without hairs, unlike some American species sometimes considered to belong in Justicia (Graham 1989). Micromorphology also provided useful characters, with seeds being reticulate, papillate, minutely or deeply rugose or with one to many crystals visible. Critical-point drying was sometimes helpful in viewing microstructure.
Studies in the southern African species of Justicia and Siphonoglossa (Acanthaceae): indumentum
Authors: Immelman K.
Published: July 2015

The trichome types present on all species of Justicia and  Siphonoglossa in the southern African region (as defined by the Flora of southern Africa) were examined with the dissecting and with the Scanning Electron Microscope. Both glandular and eglandular trichomes were observed, the former comprising both sessile, peltate glands and stalked glands of various lengths. Eglandular trichomes are either straight or sharply bent (anvil-shaped), and comprise two to many cells. They are either smooth or have raised ornamentation on the cell walls. The presence and morphology of the trichomes on various organs is recorded and measured, and the range of trichomes seen was illustrated. The possible significance of trichome type and ornamentation in the taxonomy and ecology of the genera is discussed.

The ecology of the False Bay estuarine environments, Cape, South Africa. 1. The coastal vegetation
Authors: O'Callaghan M.
Published: July 2015

The vegetation in and around eleven estuaries flowing into False Bay was surveyed during 1980 and 1981. Use was made of colour aerial photographs and a combination of dominance and phytosocioiogical techniques. Of the communities established, three are aquatic and four are described as emergent or wetlands. Of the terrestrial communities, five are described as fynbos and four occur on coastal sands. One community consists solely of alien plants. The communities thus classified generally compare well with those discussed by other workers in the area. However, differences due to the destruction and disturbance of the vegetation are commented upon.

Studies in the genus Riccia (Marchantiales) from southern Africa. 23. R. bullosa: typification and a full description
Authors: Perold S. M.
Published: July 2015

In the protologue of Riccia bullosa, Lindenberg (1829) based his vague and incomplete description of the taxon on two heterogeneous elements: a specimen from Portugal and one from the Cape. Stephani (1898) retained the name Riccia bullosa for the Cape element and referred the Portuguese plant to  Exormotheca welwitschii (Stephani 1899). Although generally accepted until 1940. K. Muller (1940) rejected Stephani's segregation and referred the Portuguese element to his new combination. Exormotheca bullosa (Link) K. Muller, based on the false assumptions that Stephani had failed to recognize that the Portuguese plant was an Exormotheca. and that the Cape plant was insufficiently known and had not been found again. Counter arguments are set out here, urging a return to Stephani’s earlier segregation. A lectotvpe for Riccia bullosa is selected, which results in the repudiation of Müller's (and Grolle's) lectotypification of Exormotheca bullosa  (=Riccia bullosa).

Salt glands in flowering culms of Eriochloa species (Poaceae)
Authors: Arriaga M. O.
Published: July 2015

Salt glands were found in Eriochloa (Paniceae-Poaceae):  E. monte\idensis, E. pseudoacrotricha and E. punctata.  They occur on the culms, rachises and secondary ramifications of the inflorescence. The glands are bicellular structures with endodermal tissue at the base. They consist of a basal cell and an apical cell, which is a collecting chamber with a large pore at the top. It is proposed to conserve the term salt gland to designate excretory structures associated with endodermal collecting tissue. The elements present in the glands (detected by the use of X-ray micro-analysis) are: Na. Mg. P. S. Cl. K with an increase of the elements from the endodermal tissue to the cap cell. Because of energy needed to transport and excrete salts, salt glands are situated at the base of the inflorescence, which is the zone of maximal development of Kranz structure. It is inferred that  Eriochloa is a facultative halophytic genus, derived recently from a halophytic ancestor.

Systematic studies in the genus Mohria (Anemiaceae: Pteridophyta). III. Comparative sporangium and spore morphology
Authors: Roux J. P.
Published: July 2015

The genera Mohria and Anemia (Anemiaceae: Pteridophyta) can be separated on both their sporangia and spores. In Mohria the capsule is globose with an apical annulus but in Anemia it is ovate-globose to cylindrical with a subapical annulus. The spores of both genera are radially symmetrical, tetrahedral and trilete with near parallel muri. The exinal sculpture in Mohria is cicatricose and in Anemia it can be canaliculate or cicatricose. In both genera the mural sets anastomose to form common muri that extend from near the distal pole to the equatorial radial region. The muri in Mohria are hollow and differ from those in Anemia which are solid or microporate. Supramural sculpturing in Mohria and Anemia is perinous. Spores of the other schizaealean ferns show no or little taxonomic affinities with Mohria and Anemia. In Actinostachys and Schizaea the spores are monolete and in  Lygodium trilete but the exinal sculpture is smooth.
Richness, composition and relationships of the floras of selected forests in southern Africa
Authors: Geldenhuys C. J.
Published: July 2015

Species lists of 14 widely separated forests representing particular geographic regions in southern Africa were used to study the size and composition of the individual floras, the similarities between them, and possible determinants of the observed patterns. The forests contain 1 438 species which belong to 155 families and 661 genera. The growth form spectra show specific patterns amongst the individual forests such as an abundance of ferns in montane forests, and of woody plants and vines in coastal forests. The richness of a forest flora increases with increasing altitudinal range within the forest. Significant linear species-area relationships exist for both woody and herbaceous species, but explain only 30% and 38% of the variation respectively in the size of the floras. In a multiple regression model the number of dispersal corridors, the proximity to other forests and mean altitude explained 81% of the variation in the number of woody species. The number of landscape types and of dispersal corridors explained 75% of the variation in number of herbaceous species. Several other factors contribute to the disproportionately large floras of relatively small forests such as at Umtamvuna, Sabie and Richards Bay. A high proportion of unique taxa are present (30% woody and 42% herbaceous species). The shared taxa show definite trends of the southward attenuation of species and the presence of elements of the Afromontane and Indian Ocean Coastal Regions.In conclusion, it is suggested that the southern Cape forests have been isolated from forests along the escarpment and mountains to the east since at least the Pliocene due to the Sundays River valley which stretches from the coast to the escarpment in the arid interior.
The recovery and dynamics of submerged aquatic macrophyte vegeta­tion in the Wilderness lakes, southern Cape
Authors: Weisser P. J. , Whitfield A. K. , Hall C. M.
Published: July 2015

Between 1979 and 1981, the submerged aquatic macrophyte vegetation in the Wilderness lakes died back significantly, and in some areas disappeared altogether. This study documents the senescent phase and describes the recovery of the plant populations between May 1982 and May 1983. In two lakes, namely Langvlei and Eilandvlei, the plant biomass approximately doubled between the winters of 1982 and 1983. Seasonal changes in species composition are documented and possible factors accounting for the collapse and recovery of the plant populations are discussed.

The taxonomic value of epidermal characters in the leaf of Heteromorpha and some related genera (Apiaceae)
Authors: Winter P. J. D. , Van Wyk B-E.
Published: July 2015

All 17 species of Heteromorpha Cham. Schltdl. (sensu Humbert 1956), all three species of Polemannia Eckl. Zeyh. and the monotypic Polemanniopsis B.L. Burtt were investigated for leaf epidermal characters. Stomatal type was anomocvtic. with an exception in only one Madagascar species, H. betsileensis. The distribution and density of stomata (on both leaf surfaces) are diagnostic for some species. The number, size and outline of normal epidermal cells are different in juvenile and adult leaves and these differences vary between species. Seven trichome types are recognized which, when combined with dispersion pattern, also serve to characterise the various species and forms.

The taxonomic history of the Ricciaceae (1937-1995) and a classification of sub-Saharan Ricciae
Authors: Perold S. M.
Published: July 2015

The taxonomic history of the Ricciaceae (1937-1995) is reviewed. Over the years many attempts have been made to subdivide and rearrange the taxa in this large and puzzling family, but consensus has still not been reached. Hepaticologists are therefore urged to undertake more revisions worldwide, using modem methods of investigation to aid them in. hopefully, coming to an eventual agreement in defining the limits of subgenera, sections, species and subspecies in the Ricciae. In addition, a classification of sub-Saharan Ricciaceae. partially based on informal groups, is herein proposed.

Studies in the liverwort genus Fossombronia (Metzgenales) from southern Africa. 2. An amendment to three species from Western Cape, described by S.W.Amell
Authors: Perold S. M.
Published: July 2015

Subsequent to his visit to South Africa in 1951, S. W. Amell (1952), described three new Fossombronia species from Western Cape, namely F. capensis, F. densilamellata and F. montaguensis. Unfortunately, however, they were not described in detail, nor were they fully illustrated. An attempt is hereby made to augment Amell’s descriptions and to illustrate his species more completely, with the aid of drawings and SEM micrographs. A distribution map is also provided. Scott Pike (1988), after examining many Fossombronia specimens of world-wide origin, concluded that the above three species were good species, aconclusion I support.
Studies in the liverwort genus Fossombronia (Metzgeriales) from southern Africa. 3. An amendment to F. spinifolia
Authors: Perold S. M.
Published: July 2015

Fossombronia spinifolia was described by Stephani (1900) from a specimen collected by Breutel at Genadendal (Gnadenthal) during his visit to the Cape, which lasted from November 1853 to April 1854 (Gunn Codd 1981). This species was not adequately described and illustrated by Stephani or by subsequent workers. Moreover, Scott Pike (1987) misapplied the epithet,  F. spinifolia, to specimens Amell had identified as  F. leucoxantha, because they (Scott Pike 1988) overlooked a capsule with ripe spores in the type specimen. An attempt is hereby made to describe and illustrate this species in greater detail in order to prevent more confusion in future.

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

The genus Echium L. (Boraginaceae) comprises about 60 species, mainly from Macaronesia. Europe, western Asia and North Africa. Two species E plantagineum L. and E. vulgare L. were introduced into southern Africa and have become naturalised. The species occur mainly as roadside weeds in the region. Echium is closely related to Lobostemon Lehm. (incl. Echiostachys Levyns), endemic in the southwestern Cape region. Pollen morphology shows a remarkable similarity between these genera, even suggesting that they could be merged. However, other characters, such as bilobed styles (Echium) versus undivided ones (Lobostemon) and the presence of an annulus, composed of a minute collar or 5-10 minute hairy lobules, at the bottom of the corolla tube inside (Echium), in contrast to hairs and/or scales at the base of the filaments (Lobostemon) contradict the pollen structure, and Echium and Lobostemon are therefore regarded as two separate genera. Significant taxonomic characters, an identification key, full descriptions, illustrations and distribution maps of E. plantagineum and E. vulgare are given.

Cytogenetic studies in the genus Pentaschistis (Poaceae: Arundinoideae)
Authors: Klopper K. C. , Spies J. J.
Published: July 2015

Cytogenetic studies of 45 specimens, representing 16 taxa of the genus Pentaschistis (Nees) Spach confirmed two basic chromosome numbers (x = 7, 13) for the genus. Chromosome numbers for five species and one subspecies are described for the first time, i.e. P. aimides subsp.  jugorum (n = 2x = 14). P. colorata (n = 2x = 14). P densifolia (n = x = 7), P. linui (n = 6x = ± 42), P. rigidissima (n = x = 7, n = 3x = 21) and P viscidula (n = 3x = 21). Polyploidy occurs frequently and new ploidy levels are described m four of the species, namely P airoides (Nees) Stapf subsp. airoides (n = 3x = 21), P. cir- rhulosa (Thunb.) McClean (n = x = 7), P. eriostoma (Nees) Stapf (n = 3x = 39+0-4B) and P rupestris (n = 4x = 28) The majority of species form young polyploid complexes. There seems to be no correlation between cytogenetic data and mor­phological groupings within Pentaschistis.

Distinguishing features of Faucaria are the characteristically dotted and toothed leaves and the structure of the seed capsule. A taxonomic review of the genus is presented, including relationship, diagnostic features, variation, distribution and ecology. The revision reduces the number of species from 33 to six:  F. bosschearui. F.felirui,  F. gratiae, F. nemorosa,  F. subintegra. and  F. tigrina. Two new subspecitic combinations,  F. felirtu subsp britteniae and  F. felina subsp tuberculosa have been made. A cladogram is included. A key to the taxa is provided and each species is described and illustrated.
The genus Amphiglossa (Gnaphalieae, Relhaniinae, Asteraceae) in southern Africa
Authors: Koekemoer M.

It is proposed that the generic concept of Amphiglossa DC. be broadened to include the genus Pterothrix DC. The two gen­era were previously separated on the presence or absence of ray florets. A thorough study of various characters showed that the type of florets was overemphasised in the past and that the pappus and cypselas provide sufficient evidence to unite the two genera The genus consists of 11 species of which  Amphiglossa celans Koekemoer.  A. grisea Koekemoer,  A. rudolphii Koekemoer and A. susannae Koekemoer are newly described A key to the species as well as detailed descriptions and distribution maps are provided. Photographs are included for each species and key characters for the genus are also illustrated.

Flora of the Kap River Reserve, Eastern Cape, South Africa
Authors: Cloete E. C. , Lubke R. A.
Published: July 2015

A detailed analysis ot the flora of the newly proclaimed Kap River Reserve (600 ha) is given. The reserve is adjacent to the Fish River and some 5 km from the Fish River Mouth It consists of a coastal plateau up to 100 m a.s.I. which is steeply dissected by the two rivers that partially form the boundary of the reserve. The flora of the reserve was sampled over a period o f three years and plants were collected in all the vegetation types of grassland, thicket and forest. 488 species were collected with a species to family ratio of 4:4. The majority of the taxa recorded represent the major phytochoria of the region. Nineteen species are endemic to the Eastern Cape, two are classed as vulnerable, five are rare, six are protected and a further seventeen are of uncertain status. The flora of the Kap River has closest affinities to that of the Alexandria Forest.
Vegetation of the Sileza Nature Reserve and neighbouring areas, South Africa, and its importance in conserving the woody grasslands of the Maputaland Centre of Endemism
Authors: Matthews W. S. , Van Wyk A. E. , Van Rooyen N.
Published: July 2015

An analysis of the plant communities of the Sileza Nature Reserve and surrounding areas (± 4 124 ha) is presented. The study area falls within the Maputaland Centre o f Endemism, which is part ot the Maputaland-Pondoland Region, a centre of plant diversity rich in endemic plants and animals. A TWINSPAN classification, refined by Braun-Blanquet procedures, revealed 12 distinct, mainly grassland plant communities. A hierarchical classification, description and ecological interpretation ot these communities are presented. The level o f the water table, either directly, or indirectly through its role in soil formation, is the deciding factor in defining plant communities on the geologically young sandy substrate. Fire is an essential factor, particularly in maintaining the woody grasslands, a rare vegetation type rich in geoxylic suffrutices. and unique to the Maputaland Centre. A comparison between the endemic complement in the subtropical coastal grasslands of Maputaland and the high-altitude Afromontane grasslands of the Wolkberg Centre of Endemism shows marked differences in grow th form and vegetation type partitioning between the two centres. This can probably be ascribed to the relative youth (Quaternary) of the Maputaland coastal plain and its associated plant communities. Notable for their richness in Maputaland Centre endemic/near-endemic taxa. the conservation of sand forest and woody grasslands should receive high priority. Afforestation with alien trees is the most serious threat to the biodiversity of the Maputaland coastal grasslands, not only because of habitat destruction, but also through its expected negative effect on the hydrology of the region
Two new species of Gladiolus (Iridaceae: Ixioideae) from South Africa and notes on long-proboscid fly pollination in the genus
Authors: Manning J. C. , Goldblatt P. , Winter P. J. D.
Published: July 2015

Gladiolus rhodanthus is a new species known from a single population on the summit of the Stettynsberg near Villiersdorp in Western Cape. South Africa The species most closely resembles G. hirsutus and G caryophyllaceus but differs from both in flower shape and markings and in its ecology and reproductive biology. It forms part of a guild of long- tubed, pink-flowered species including  Erica praecox, Pelargonium radiatum and  Watsonia paucifolia which are pollinated by an undescribed long-proboscid fly. Moegistorhynchus sp nov. (Diptera : Nemestrinidae). Gladiolus sekukuniensis is a new species known from three populations south of the Strydpoortberge in Northern Province It closely resembles G. permeahilis subsp  edulis in vegetative features and in flower form, but differs from it in flower colour and in the elongate peri­anth tube. These floral features are apparently adaptations to pollination by long-proboscid flies.

Combining floristic and growth form composition in a gradient- directed vegetation survey of Matjiesrivier Nature Reserve, Western Cape, South Africa
Authors: Lechmere-Oertel R. G. , Cowling R. M.
Published: July 2015

The floristically complex vegetation of Matjiesrivier Nature Reserve (MNR). which spans the ecotone between the Fynbos and Succulent Karoo Biomes in the eastern Cederberg Mountains, Western Cape, was surveyed using a gradient-directed transect (gradsect). The gradsect was aligned with a topo-ciimatic aridity gradient across MNR. The vegetation was classified using TWINSPAN. based on a combination of floristic and growth form characteristics, and an understanding of the main ecological gradients controlling vegetation distribution. The final classification described seven robust and eco­logically meaningful communities that represented a trade-off between statistical rigour and practicality for management. The seven communities were mapped using a geographical information system (GIS).
