Alterations to the inventory of about 24 000 species and infraspecific taxa of bryophytes and vascular plants in southern Africa are reported for the year 1988. The inventory, as currently maintained in the Taxon component of the PRECIS system, contains the accepted name for each taxon, synonyms previously in use as accepted names during the past half-century, and literature references necessary to identify species in each genus and to establish the synonymy. The inventory is updated as new research affecting plant classification in southern Africa is published. During 1988 there were 744 alterations, affecting about 3% of the total number of taxa.

Ascospore development in Ceratocystis sensu lato (Fungi): a review
Authors: Van Wyk P. W. J. , Wingfield M. J.
Published: July 2015

Ceratocystis. Ceratocxstiopsis and  Ophiostoma are important pathogens of trees and some agricultural crops and have recently been found on proteas and forest trees in South Africa. Taxonomic controversy exists regarding these genera and ultrastructural studies on the development of asci, uniquely shaped ascospores and centrum structure are inadequate. This rev iew summarises current knowledge of ascospore shape and development of the centrum obtained from light and electron microscope studies of Cemtocystis sensu lato. Important questions requiring further investigations are outlined. It is furthermore proposed that additional ultrastructural studies are required to clarify the current taxonomic disagreement in this group. Such studies could also identify relationships between these fungi and other Ascomycetes.
Studies in the genus Riccia (Marchantiales) from southern Africa. 19. Two new species: R. pulveracea., section Pilifer and R. bicolorata, section Riccia, group ‘Squamatae’
Authors: Perold S. M.
Published: July 2015

R. pulveracea, specimens of which were collected by Duthie and tentatively referred to R concava by her. is described here, following the recent collection of fresh material. This species is distinguished from other members of section  Pilifer (Volk 1983) by low. generally two-celled, free-standing dorsal cell pillars, which when dry, appear powdery, hence the specific epithet. R bicolorata. section Riccia. group 'Squamatae' occurs in the Cape but is rarely collected, and is characterized by bicoloured scales, of which the wide hyaline margins are heavily encrusted with calcium deposits. It is somewhat similar to R. pottsiana, but larger, and its scales are not so regularly arranged.
Studies in the genus Riccia (Marchantiales) from southern Africa. 21. R. stricta, R. purpurascens and R. fluitans, subgenus Ricciella
Authors: Perold S. M.
Published: July 2015

Lindenberg (1836) regarded and published Riccia stricta as a variety of R. fluitans L. Subsequently, Nees (1838) and Gottsche et al. (1846) also treated it as a variety. Trevisan (1877) raised its rank and published the epithet,  Ricciella stricta Trevis.Ricciella is, however, regarded as a subgenus; Ricciella stricta is, therefore, transferred to Riccia stricta (Lindenb.) Perold.It is described in detail and illustrated.  R. purpurascens Lehm. Lindenb., a related endemic species, is also more fully described than before and illustrated.  R. fluitans L. apparently does not occur naturally in southern Africa. As far as is known, a single local specimen of it was introduced.

Published: July 2015

The grassland vegetation on the coast of north-eastern Pondoland was analysed after sampling of 113 quadrats in Mkambati Game Reserve. Data were summarised using TWINSPAN and DECORANA multivariate procedures. Several communities and subcommunities are recognized and described in relation to measured abiotic variables. A primary gradient from the shore inland is evident, corresponding with changes in altitude, soil conductivity, soil organic matter and soil texture. Time since the last fire influences the invasion of shrubland species.

Published: July 2015

Chromosome numbers of 46 specimens of grasses, involving 24 taxa from South Africa and Australia, have been determined during the present study. For the first time chromosome numbers are given for Eragrostis sarmentosa (Thunb.) Trin. (n = 20). Panicum aequinerve Nees (n = 18),  Digitaria argyrograpta (Nees) Stapf (n = 9) and D. maitlandii Stapf C.E. Hubb. (n = 9). Additional polyploid levels are described for Diplachne fusca (L.) Beauv. ex Roem. Schult. (n = 10) and Digitaria diagonalis (Nees) Stapf var.  diagonalis (n = 9).B-chromosomes were observed in several different specimens. The presence of B-chromosomes often results in abnormal chromosomal behaviour during meiosis.
The chromosomes of Chortolirion and Poellnitzia (Asphodelaceae: Alooideae)
Authors: Smith G. F.
Published: July 2015

The somatic chromosomes of Chortolirion angolense (Baker) A. Berger and Poellnitzia rubriflora (L. Bol.) Uitewaal have been studied. Both taxa are monotypic genera in the subfamily Alooideae of the Asphodelaceae. Prior to this study Chor­tolirion had not been cytologically examined, while karyograms and idiograms have never been presented for Poellnitzia. Chortolirion and Poellnitzia are diploid with 2n = 14 chromosomes and with a bimodal karyotype typical of the entire subfamily, comprising four pairs of long chromosomes and three pairs of short chromosomes. For Poellnitzia minute structural differences in karyotype morphology were noted between observed and published data, especially with regard to the presence of satellites.

Published: July 2015

The physiography and climate of Inaccessible and Nightingale Islands are briefly discussed. The vegetation and the major plant associations are described. Notes are given on the ecology and distribution of each taxon. Taxa newly recorded for Inaccessible Island include Agrostis goughensis, A.holgateana, A. wacei, Calamagrostis deschampsiiformis, Carex thouarsii var.  recurvata, Conyza albida, Elaphoglossum campylolepium and  Uncinia meridensis. One species, C.  albida, is alien to the Tristan group. Two native ferns Asplenium platybasis var.  subnudum and Blechnum australe were found on Nightingale Island for the first time, and the presence of introduced Malus domestica orchards was recorded. Two unidentified taxa were found that may represent new species:  Elaphoglossum sp. at Inaccessible Island and Apium sp. at both Inaccessible and Nightingale Islands. The total number of vascular plant species recorded at Inaccessible and Nightingale Islands now stands at 98 and 43, respectively, of which 26 (28%) and seven (16%) are introduced species. Only Airiplex plebeja and two species of Cotula occur at Nightingale Island but are absent from Inaccessible Island.

Flora and vegetation of the Mbonambi Beach Arcuate Scar on the Zululand dune barrier, Natal, South Africa
Authors: Weisser P. J. , Smith E. C. A. , Backer A. P. , Van Eeden S.
Published: July 2015

A hundred and seventy-nine species belonging to 63 families were found in 13 communities in the Mbonambi Arcuate Scar. This is a rare type of dune valley that is described here and its vegetation is mapped. The great botanical diversity in a small area (7 ha) can be related to the variety in ecological conditions and the juxtaposition of pristine and disturbed areas. Because most of the adjacent area has been mined and this type of dune valley is rare, it deserves a high conservation status rating. A  Pereskia aculeata infestation was found that requires urgent attention.

Published: July 2015

A survey of the mycorrhizal status of plants growing in the Cape Floristic Region of South Africa was undertaken to assess the range of mycorrhizal types and their dominance in species characteristic of this region. Records were obtained by ex­amining the root systems of plants growing in three Cape lowland vegetation types, viz. West Coast Strandveld, West Coast Renosterveld and Sand Plain Lowland Fynbos for mycorrhizas, as well as by collating literature records of mycorrhizas on plants growing in the region. The mycorrhizal status of 332 species is listed, of which 251 species are new records. Members of all the important families in this region have been examined. Mycorrhizal status appears to be associated mainly with taxonomic position of the species. Extrapolating from these results, we conclude that 62% of the flora of the Cape Floristic Region form vesicular-arbuscular mycorrhizas, 23% have no mycorrhizas, 8% are ericoid mycorrhizal, 2% form orchid mycorrhizas, whereas the mycorrhizal status of 4% of the flora is unknown. There were no indigenous ectomycor- rhizal species. The proportion of non-mycorrhizal species is high compared to other ecosystems. In particular, the lack of mycorrhizas in several important perennial families in the Cape Floristic Region is unusual. The diversity of nutrient acquir­ing adaptations, including the range of mycorrhizas and cluster roots in some non-mycorrhizal families, may promote co­existence of plants in this species-rich region.
The vegetation of the northeastern Orange Free State, South Africa: physical environment and plant communities of the Ea land type
Authors: Eckhart H. C. , Van Rooyen N. , Bredenkamp G. J.
Published: July 2015

The research was carried out in the Ea land type of the northeastern Orange Free State, with the objective of reclassifying and refining Acocks’s veld types. TWINSPAN classification results were further refined by Braun-Blanquet procedures. The 100 relev^s distributed over the Ea land type resulted in the recognition of four major vegetation types which may be divided into nine plant communities. The communities were hierarchically classified, described and ecologically interpreted. DECORANA ordination was used to determine vegetation/environmental gradients and relationships.
The vegetation of the southern Langeberg, Cape Province. 2. The plant communities of the Marloth Nature Reserve
Authors: Mcdonald D. J.
Published: July 2015

The Marloth Nature Reserve, encompassing the mountain catchments of the southern Langeberg immediately above Swellendam, Cape Province. South Africa, is described. The vegetation of the reserve was sampled along a transect representing the variation in plant communities over the range from the lower south to the lower north slopes. Eighty-three sample sites were subjectively located in mature stands of fynbos vegetation (10 years old). The relev£ data were initially classified using TWINSPAN and then refined by Braun-Blanquet (BB) phytosociological procedures. The Afromontane Forest patches which occur mainly on the lower south slopes were not sampled but are briefly discussed. The fynbos plant communities are described, based on tables, and a hierarchical classification is proposed.
Systematic studies in the genus Mohria (Anemiaceae: Pteridophyta). IV. Comparative gametophyte morphology in Mohria and Anemia
Authors: Roux J. P.
Published: July 2015

The sporophyte morphology in Mohria and Anemia (Anemiaceae) is dissimilar. However, similarities in their anatomy, trichomes, spores and chromosome numbers show clearly that these genera are related. The contribution of the gametophyte to the classification and phytogeny of the Pteridophyta is largely neglected. The gametophyte of Anemiaceae is primitive in many features when compared with that of other leptosporangiate ferns. The prothallus of Mohria is considered more advanced than that of Anemia in the germination pattern of the spores, the presence of mycorrhiza in the cushion, the permanently lateral position of the meristematic region and the simpler trichome types.

The development of the ovule and the embryo sac of five of the 17 species of Lycium and of one hybrid, recorded for southern Africa, was investigated. All specimens of four of the species and the hybrid (between a hermaphroditic and a functionally dioecious species) were found to be functionally dioecious: they express only one sex, although both male and female organs are present in the same tlower. One species was hermaphroditic. The embryo sacs of all species, and of the hybrid, were of the normal eight-nucleate Polygonum type. The structure of the ovary and the development of the embryo sac are similar to those of L europaeum L. The absence of unreduced embryo sacs indicates that apomixis does not occur at any ploidy level in the species studied.

Inflorescence morphology of Lachiiaea and Cryptadenia (Thymelaeaceae)
Authors: Beyers J. B. P. , Van der Walt J. J. A.
Published: July 2015

The current delimitation of Lachnaea L. and Cryptadenia Meisn. is based on the inflorescence morphology. In Lachnaea both indeterminate and determinate inflorescences occur, whereas in Cryptadenia only determinate inflorescences are present. The indeterminate inflorescences in  Lachnaea are capitate or umbellate. The determinate inflorescences in both genera comprise a solitary, terminal flower. It is concluded that the two genera cannot be distinguished on inflorescence structure.

In this, the ninth and final article in the series on southern African Marchantiales. a taxonomic account is given ol the genus Marchantia which is locally represented by five species. Two of the three subgenera that are recognized, namely subgenus Marchantia (with two species, M. polymorpha subsp.  ruderalis and M. berteroana). as well as subgenus Chlamidium (Corda) Bischl. which is divided into three sections, namely  Paleaceae (with M. paleacea subsp.  paleacea). Chlamidium (with M. pappeana subsp. pappeana) and Papillatae (with M. debilis) are treated. The third subgenus. Protomarchantia Schust.. is absent from the region. Corrections need to be made to the Marchantia species given in Magill Schelpe's (1979) checklist and in Arnold De Wet (1993). Descriptions and illustrations of the taxa together with distribution maps, their ecology and a key to the subgenera and species are provided. Only traditional taxonomic methods were employed and this treatment closely follows that of Bischler-Causse ( 1993a). the recognized world authority on the group. All southern African specimens held at BOL and PRE. as well as a few from other herbaria have been studied and some new collections have been added. It is shown that M. polymorpha subsp.  ruderalis has been introduced, as it is only known from local nurseries. The presence here of M. paleacea subsp. paleacea is confirmed, although it is rare. Otherwise little that is new could be added to the exhaustive studies by Bischler-Causse (1993a).

Studies in the liverwort genus Fossombronia (Metzgeriales) from southern Africa, 1. Three new species from Northern Province, Gauteng and Mpu­malanga
Authors: Perold S. M.
Published: July 2015

Three new species of Fossombronia from Northern Province, Gauteng and Mpumalanga (formerly Transvaal) are described: F.  gemmifera, F. glenii and F. straussiana. F. gemmifera is distinguished by a highly convoluted pseudoperianth, the frequent presence of gemmae produced dorsally on the stem, lamellate spores and mostly rather short elaters; F. glenii can be recognized by a smallish, deeply lobed pseudoperianth, perigonial bracts with finger-like projections shielding the antheridia and by spinous spores; F. straussiana is distinct by its hyaline or brownish rhizoids, by its dense, frilly leaves, its pseudoperianth with lamellate lateral outgrowths, by spore ornamentation that usually has inclusions in the incomplete areolae and by the elaters which are finely papillose.

Composition and biogeography of forest patches on the inland mountains of the southern Cape
Authors: Geldenhuys C. J.
Published: July 2015

Patterns in species richness of 23 small, isolated forests on the inland mountains of the southern Cape were studied. Species richness of woody plants and vines of the Kouga-Baviaanskloof Forests was higher than in the western mountain complexes, where species richness in the more southern Rooiberg and Kamanassie Mountains was higher than in the Swartberg range. The Rooiberg, a dry mountain with small forests far away from the coastal source area, had more species than, and contained many species which are absent from, the larger, moister forests of the Kamanassie which are closest to the coastal source areas. Neither altitude nor distance from the source area, the forests south of the coastal mountains, nor long-distance dispersal, adequately explained the variation in species richness. The variations are best explained in terms of dispersal corridors along the Gouritz and Gamtoos River systems which connect the coastal forests with the inland mountains. The distribution patterns of four species groups in relation to the geomorphological history of the two river systems provide relative dates for the expansion and contraction of temperate forest, subtropical forest and subtropical transitional thicket in the southern Cape.

A taxonomic account is given of the monotypic genus Maurocenia Mill. Maurocenia frangula Mill, has a restricted range and is endemic to the Cape Peninsula and the West Coast National Park. Western Cape. Maurocenia frangularia (L.)Mill., the species name and author citation widely used in the past, is incorrect. It is characterized by. among others, pendulous ovules and gynodioecy, rare states in the Celastraceae. Maurocenia is apparently most closely related to the southern African genus Lauridia Eckl.

Authors: Perold S. M.
Published: July 2015

Fossombronia capensis S.W.Amell var. spiralis Perold, var. nov. from Western Cape is described. It is distinguished from the typical variety by a suite of characters, the most obvious being the strong spirals in the elaters. In  F. capensis var. capensis the spirals are weak except for two Arnell collections in which they are quite strong. Subtle differences in spore ornamentation are then, perhaps, the most definitive character to separate the two varieties.

Ordination and classification of vegetation of Songimvelo Game Reserve in the Barberton Mountainland, South Africa for the assess­ ment of wildlife habitat distribution and quality
Authors: Stalmans M. , Robinson E. R. , Balkwill K.
Published: July 2015

A vegetation survey was undertaken of the 49 000 ha Songimvelo Game Reserve in the Barberton Mountainland of Mpumalanga. South Africa with the aim to identify constituent plant communities and to assess their relative value to wild herbivores. The vegetation is highly diverse with representation of three biomes: Savanna. Grassland and Forest A total of 428 plots were sampled by means of a semi-quantitative technique. Data were subjected to ordination (CANOCO) and clas­sification (PATN). The composition of the 19 distinct communities is determined through an intricate combination of environmental factors as evident from the ordination results. Firstly drainage line' position is critical, followed by land use history and further by the interplay between elevation and geology. These findings are in line with results obtained from other studies along the eastern Escarpment. Alluvium, mafic and ultramafic lavas support mixed veld, whereas felsic lavas, sandstones and quartzites support sour veld which has a very low forage value in the dry’ season. Each community, through its specific species assemblage, structure and location, forms a distinctly different habitat in terms of its value to the various species of herbivores in the SGR

Morphology and anatomy of the rhizome and frond in the African species of Polystichum (Pteropsida: Dryopteridaceae)
Authors: Roux J. P. , Van Wyk A. E.
Published: July 2015

The generic circumscription of the polystichoid ferns within the Dryopteridaceae and their relationships has been and still is much debated. Although floristic accounts for Polystichum are available for many parts of the world, its morphology and evolutionary trends within the genus are still poorly understood. In this study, primarily based on the  Polystichum species from Africa and neighbouring islands, the morphology and anatomy of the rhizome and frond are addressed. Several species from other genera within the Dryopteridaceae are used for comparison, to gain a better understanding of generic affinities and evolution in this family.

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

The genus Ehretia P.Browne in southern Africa is revised. Six species and five subspecies of Ehretia are currently rec­ognized in southern Africa, of which E. alba Retief A.E.van Wyk, E. namibiensis Retief A.E.van Wyk subsp. namibi­ensis,  E. namibiensis subsp.  kaokoensis Retief A.E.van Wyk,  E. rigida subsp.  silvatica  Retief A.E.van Wyk and E. rigida subsp. nervifolia Retief A.E.van Wyk are newly described. The genus is widely distributed in the region and occurs in a variety of habitats, ranging from the forests of the Eastern Cape to the hot, arid, semidesert parts of Namibia. Members of Ehretia in southern Africa are predominantly multistemmed shrubs or small trees. Characters of the leaf, the trichome com­plement, inflorescence and corolla are used to distinguish between the different species. A key to the species, distribution maps and illustrations of various micro- and macromorphological as well as palynological features are provided.
