Authors: Burrows J. E. , Edwards T. J.
Published: July 2015

Recent research has necessitated a review of the nomenclature of the genus Ophioglossum in Africa. This paper establishes a new species, O. caroticaule J. E. Burrows, a new subspecies, O. vulgatum L. subsp. africanum Pocock ex J. E. Burrows, and a change in status, O. latifolium (Prantl) J.E. Burrows (basionym: O. gomezianum var.  latifolium Prantl). Lectotypification is provided for O. gracillimum Welw. ex Hook. Bak., O. lusoafricanum Welw. ex Prantl, O. latifolium (Prantl) J.E. Burrows, and 0. rubellum Welw. ex A. Braun. Nomenclatural problems in O. lancifolium Presl are discussed.

Flowering phenology in the arid winter rainfall region of southern Africa
Authors: Struck M.
Published: July 2015

The impact of physical factors on the flowering phenology of a succulent karroid community in the winter rainfall region of the northwestern Cape, South Africa, based upon a three year study on permanent plots, is examined, (in the permanent plots, flowering of the shrubby species extended over a period of 4 to 4'/i months each year, while blooming ot the therophytes peaked m the first half of the flowering season. Species composition and numbers of individuals in the therophytes and geophytes offering flowers varied greatly according to the pattern and amount of seasonal precipitation. Despite these variations a consistent flowering sequence between the years was observed. Possible relations between the flowering phenology and the climatic variables are discussed in detail. The present data suggest that the onset of flowering is determined indirectly by the first drop in temperature in autumn, indicating the beginning of the rainy season and presumably the start of the growing period, and/or by the increase of temperatures in the beginning of spring. The pattern and amount of rainfall within a given season mainly influenced the duration of anthesis and the number of flowers produced.

A taxonomic re-assessment of Ammocharis herrei and Cybistetes longifolia (Amaryllideae: Amaryllidaceae)
Authors: Snijman D. A. , Williamson G.
Published: July 2015

The infructescence of the poorly known Ammocharis herrei F.M. Leight. is similar to that which is diagnostic for Cybistetes longifolia (L.) Milne-Redh. Schweick. In the absence of distinct morphological differences A. herrei is placed into synonymy under C. longifolia. Plants of the amplified C.  longifolia have fewer, large seeds in Namaqualand and the Richtersveld and smaller, more numerous seeds in the Western Cape. This pattern is postulated to reflect divergent strategies of resource allocation in different habitats. It is suggested that the infructescence of C.  longifolia. a highly derived structure suited to tumbling, evolved from the unspecialised condition in Ammocharis as an adaptation to the high winds of southwestern Africa.

A new serotinous species of Cliffortia (Rosaceae) from the southwestern Cape with notes on Cliffortia arborea
Authors: Oliver E. G. H. , Fellingman A. C.
Published: July 2015

A remarkable new species,  Cliffortia conifera E.G.H. Oliv. Fellingham, from the Anysberg, Ladismith District, is described and compared to its closest ally in the genus, Cliffortia arborea Marloth, which is widespread along the escarpment of the Great Kanxt from ( alvinia in the north to Beaufort West in the southeast. It is unique in the genus for its serotinous cone-like synflorescences which are borne on determinate lateral branchlets occurring in zones on the main branches. A similar serotinous condition exists in  C. arborea. but the inflorescence axis is the main branch. The serotinous inflorescences are complex synflorescences consisting ol numerous, highly condensed, double racemes (homoeothetic dibotrya). To date serotinous inflorescences have not been recorded in Cliffortia. C. arborea and C. conifera are included in section Arboreae, the description of which is emended here.

Morphological and ultrastructural variations in Scliizjaea pectinata (Schizaeaceae: Pteridophyta)
Authors: Parkinson B. M.
Published: July 2015

Schizaea pectinata (L.) Sw. was collected from the extreme ends of its geographical range in South Africa for a study of sporangial development, sporogenesis and tapetal organisation. Differences were noted in the gross morphology , in sporangium size, spore size and in the patterning of the outer exospore from the two sites. Coiled structures were associated with the development of the inner perispore in spores collected from the Transvaal, whereas dense, heterogeneous bodies were associated with the formation of this layer in spores from the Cape. Differences were also noted in the organisation of the tapetum. A cellular, parietal tapetum and a plasmodial tapetum were present in the Cape material when the spores had developed the sculptured outer exospore. In sporangia from the Transvaal, however, only a plasmodial tapetum was present at the same stage of sporoderm development. A detailed study of S. pectinata throughout its distribution is required to determine the taxonomic importance of these findings.
The saltmarsh vegetation of the lower Berg River
Authors: O'Callaghan M.
Published: July 2015

The lower Berg River supports approximately 250 ha of estuarine saltmarsh vegetation. Species distribution patterns, as sampled along six transects, are described. Elevation above mean sea level (MSL) is proposed as a strong determinant of these patterns. However, there are no typical patterns. The patchy and irregular distribution patterns possibly result from an inconsistent relationship between species distribution and salinity, tidal inundation and/or competitive interactions.
The saltmarsh vegetation of the lower Uilkraals River
Authors: O'Callaghan M.
Published: July 2015

Approximately 40 ha of saltmarsh exist around the Uilkraals River. The distribution patterns of species in these marshes are described and compared with patterns found in other marshes in the Western Cape. The marshes might superficially resemble a mosaic of species, but each element of the mosaic could be compared with vegetation in other systems. Peculiar salinity and tidal features are postulated as having a great influence on species distributions at this river.
The marsh vegetation of Kleinmond Lagoon
Authors: O'Callaghan M.
Published: July 2015

The vegetation of Kleinmond Lagoon suggests that this system is in transition from an estuary to a coastal lake. Two major types of vegetation were recognized, one which is subjected to soil and water conditions of marine origin and the other which is subjected to conditions of terrestrial origin. These vegetation types are discussed and compared to the vegetation of other estuarine systems. Artificial manipulations of the mouth seem to have resulted in sediment deposition and a freshening of the system. These unseasonable manipulations also threaten the continued existence of a number of species in the system.

The generic delimitation of Lachnaea and Cryptadenia (Thymelaeaceae)
Authors: Beyers J. B. P. , Van der Walt J. J. A.
Published: July 2015

The current generic delimitation of Lachnaea L. and  Cryptadenia Meisn. was investigated. A multidisciplinary approach was followed. This included a study of the habit, phyllotaxis, morphology and anatomy of the leaves and flowers, pollen morphology and karyology. No major differences were found between the two genera. The range of variation of certain diagnostic characters of these genera is such that the genera merge into each other. It was concluded that the two genera are congeneric and the inclusion of Cryptadenia within Lachnaea is proposed.

Preliminary ethnobotanical studies of the Rwenzori Mountain forest area in Bundibugyo District, Uganda
Authors: Oryem-Origa H. , Kakudidi E. K. Z. , Katande A. B. , Bukenya Z. R.
Published: July 2015

Ethnobotanical studies of the Rwenzori Mountain forest area in Bundibugyo District in Uganda were carried out between May and December 1991, and covered the northern part of the Rwenzori Mountain slopes occupied by the Bakonjo people. The presence of a major footpath through the forest with numerous utility trails radiating from it showed that some forest resources are being sought by the local population. Plant biodiversity is high, as is indicated by the fact that in a study plot of only 4 250 m , a total of 115 plant species, 101 genera and 57 families were identified from a collection of 300 plant specimens. Seventy-seven plant species were found to be of some importance to the local communities. Out of the 77 useful plant species recorded:  22 species were used for medicinal purposes; 16 for firewood; 13 for construction, joinery and furniture;  12 for craftwork; 10 provided edible fruits and vegetables; and 27 were used for a variety of other purposes. These other purposes include construction of shrines, covering of granary floors, use as toilet paper, carry ing luggage, and fodder for goats, sheep and cattle. Arundinaria alpina K. Schum. (bamboo) is the species that is most extensively harvested from the forest.
Vegetation structure and small-scale pattern in Miombo Woodland, Marondera, Zimbabwe
Authors: Campbell B. M. , Cunliffe R. N. , Gambiza J.
Published: July 2015

The aim ol this paper is to describe woodland structure and small-scale patterning of woody plants at a miombo site, and to relate these to past disturbance and soil properties. Brachystegia spiciformis Benth. and Julbemardia globiflora (Benth.) Troupin were the most frequent woody plants at the five hectare site, with size-class distributions which were markedly skewed towards the smaller size classes. The vegetation structure at the site and the increase in basal area over the past thirty years point to considerable disturbance prior to the present protected status. Six woodland subtypes were identified, grouped into two structural types: open and closed woodland. The distribution of woodland subtypes related closely to certain soil properties. It was hypothesized that the distribution of open and closed woodland is stable and a positive feedback mechanism by which this occurs is postulated.

Morphological and biochemical genetic evidence for hybridization in the genus Centella (Apiaceae), with notes on phylogenetic and taxonomic implica­tions
Authors: Schubert M. T. R. , Van Wyk B-E. , Van der Bank F. H. , Van der Bank M.
Published: July 2015

The main aim of this paper is to explore the occurrence of hybridization in the genus Centella. Morphological as well as genetic characters are investigated to confirm the identity of a putative hybrid between C.  triloba and C. macrocarpa. These two independent data sets, one from enzyme electrophoresis and one from morphology, are compared and interpreted by means of cladistic analysis.  Centella glauca and C.  virgata were included in the analysis and the effect of hybridization on cladistics is demonstrated. Hybridization gives a new perspective on infrageneric relationships within the genus Centella, as it may have obscured discontinuities between previously discrete infrageneric groups.

The above three southern African species were described during the nineteenth century, but the descriptions are brief and mostly inadequate. The practice, albeit for justified financial reasons, of dividing collections (which were often mixed) and of distributing the parts to different herbaria, has led to some later authors applying the specific epithets to the wrong components. This has caused a great deal o f confusion, and much time and effort have been expended in sorting out these mis­applications. This paper aims to correct and to report on some past mistakes. Detailed descriptions, illustrations and a distribution map of these three species are accordingly provided.

Published: July 2015

The survey of a natural Karoo pasture from 1978 to 1982 showed that a wealth and variety of fungi were present in the semidesert environment. Hyphomycetes and Coelomycetes represented 45.8% and 34.6% respectively of the taxa identified. A total of 135 genera was identified of which Altenaria altemata, Cladosporium spp. and Fusarium spp. of the Hyphomycetes, Phoma spp., Ascochyta spp. and  Camarosporium spp. of the Coelomycetes and Leptasphaerulina spp., of the Ascomycetes represented the most prevalent fungi in this order. This survey has shown conclusively that Pithomyces chartarum, which is associated with photosensitivity diseases of sheep, can always be recovered from the veld if the correct isolation techniques are employed. A number of new records for South Africa, as well as undescribed species, have been found, highlighting the necessity of correct methods and intensity of approach.

The floristics of Sand Forest in northern KwaZulu-Natal, South Africa
Authors: Kirkwood D. , Midgley J. J.
Published: July 2015

We use multivariate analyses (ordination and classification) to assess both the floristic uniqueness of the woody vegeation of Sand Forest in relation to a range of other forest types in the region, and the range of variation within Sand Forest. Two broad Sand Forest subtypes and related Ecotonal Forests are described and grouped under the term Tropical Dry Forest, distinct from all evergreen forests in South Africa. Sand Forest, a dry semi-deciduous type in northeastern KwaZulu-Natals defined by the presence of the canopy dominant Cleistanthus schlechteri as well as Hymenocardia ulmoides, Psydrax fragrantissima, Croton pseudopulchellus and  Drypetes arguta. Sand Forests form a cohesive group in both DCA and TWINSPAN analyses, with similar composition of canopy dominants at sampled sites. This implies that ecological funcioning is similar across the geographical range in northeastern KwaZulu-Natal. However, turnover of subdominant species between recognisable Sand Forest types emphasizes the need to conserve the full range of extant forests.
The presence of synaptic and chromosome disjunction mutants in Cenchrus ciliaris (Poaceae: Paniceae)
Authors: Visser N. C. , Spies J. J. , Venter H. J. T.
Published: July 2015

Synaptic mutants are present in  Cenchrus ciliaris L This species, due to the presence of linear bivalents and occasion­al trivalents and quadrivalents, is an intermediate desynaptic species. In addition, geographical distribution and environmental factors, such as high temperatures and low humidity, could also have had an influence on the desynapsis observed.The disjunction of chromosomes during anaphase I was mostly abnormal in this desynaptic species. Precocious disjunction of chromosomes into chromatids occurred during anaphase I Due to the high incidence of this chromosome abnormality, a mutant gene,  'pc'  responsible for the disjunction of chromosomes, must be present. The absence of cytokinesis in one specimen indicates a recessive mutant gene,  'va' to be active in this species.

Leaf anatomy of the genus Passerina (Thymelaeaceae): taxonomic and ecological significance
Authors: Bredenkamp C. L. , Van Wyk A. E.
Published: July 2015

A comparative anatomical study was made of the genus Passerina comprising 20 species and four subspecies, most of which are endemic to southern Africa. It showed that anatomical variation is useful in species recognition and classification. Anatomical characters typical of Thymelaeaceae and displayed in Passerina include isobilateral leaves, a papillate cuticular membrane, mucilaginous epidermal cell walls, a parenchymatous bundle sheath and extraxylary sclerenchyma fibres. Vascular bundles of the leaf lack intraxylary phloem. Characters common to  Passerina are inverse-dorsiventral and epis- tomatic leaves, inverted palisade parenchyma and an abaxial hvpodermal sclerenchymatous sheath. Orientation of the main vascular bundle in relation to the epidermis and mesophyll allows the recognition of four leaf structural types and ten states, according to which all species can be characterized and grouped. Functionally many anatomical features of the leaf in Passerina are interpreted as adaptations to the Mediterranean climate of the Cape Floristic Region, where most species occur.

Taxonomic significance of inflorescences, floral morphology and anatomy in Passerina (Thymelaeaceae)
Authors: Bredenkamp C. L. , Van Wyk A. E.
Published: July 2015

Comparative studies were undertaken on the inflorescence, bracts and floral morphology of all taxa of the genus Passerina L. in southern Africa. Information is given in tabular form and a key based on bract morphology is presented.Floral morphology supported the status of the intrageneric taxa and also proved to be of taxonomic significance in the genus. Controversy surrounding the interpretation of a number of floral morphological structures in  Passerina has been resolved. Morphological and anatomical evidence allowed a re-interpretation of the structure of the receptacle, hypanthium and sepals, ovary type and position, structure of the seed coat, ovule type and position, obturator, fruit and seed. On this basis an authentic generic description of the floral morphology was compiled.  Passerina is distinguished by the following set of characters, a very short floral receptacle, tubular hypanthium, petaloid calyx, absence of petals and petaloid scales, diplostemonous dimorphic androecium, extrorse anthers, superior ovary, anatropous, ventrally epitropous ovule, an obturator of elongated cells, a I-seeded berry or an achene and tegmic seed with nuclear endosperm becoming cellular throughout.On this basis the flower in Passerina is considered a phylogenetically advanced structure, supporting the view that the genus is advanced within the Thymelaeoideae. The proposed taxonomic relationship between Thymelaeaceae and Malvales is confirmed by floral morphological evidence.

Taxonomy of the Passerina filiformis complex (Thymelaeaceae)
Authors: Bredenkamp C. L. , Van Wyk A. E.
Published: July 2015

Revision of the genus Passerina L. indicated a new delimitation of taxonomic entities within the Passerina filiformis L. complex. Evidence from leaf anatomy greatly assisted in the recognition of taxa.  P. filiformis is here divided into two sub­species. namely P. filiformis subsp.  filiformis and P. filiformis subsp. glutinosa (Thoday) Bredenkamp A.E.van Wyk. and a new species. P. montivagus Bredenkamp A.E.van Wyk, which is also described. The new taxa are geographically separated: subsp. filiformis ranges from Piquetberg in the north through the Cape Peninsula in the south, where it is quite com­mon. to Attaquaskloof in the southwestern Cape: subsp. glutinosa occurs along the coast between Vredendal and St Helena Bay; and  P. montivagus has a wide distribution from Mossel Bay and Oudtshoom in the south through Eastern Cape and along the Great Escarpment northwards to Zimbabwe, with outliers in Tanzania.

Biogeographv of Oxalis (Oxalidaceae) in South Africa: a preliminary study
Authors: Oberlander K. C. , Dreyer L. L. , Elser K. J.
Published: July 2015

Oxalis L ,  commonly called sorrel,is a large and cosmopolitan taxon that has undergone spectacular speciation within southern Africa (± 270 taxa). and more specifically within the winter rainfall regions of the western Cape Region (CR). The main objective of this study w as to analyse the geographical distribution of Oxalis in South Africa in relation to currently defined phytogeographic units. The observed patterns of biodiversity and endemism within South African members of the genus show interesting disjunctions and concentrations of species.  Oxalis is one of the few CR taxa that is shared between the core Fynbos and Succulent Karoo Biomes, and this study therefore provides a novel insight into evolutionary trends across, and not only w ithin. these phvtogeographic units. The major centre for diversity for Oxalis is situated on Table Mountain and the northern areas o f the Cape Peninsula (grid square 3318CD). Subsidiary centres are located in the Clanwilliam/Niewoudtville and Kamiesberg regions. The reported patterns in Western Cape suggest that  Oxalis species richness has been generated and retained in areas w hich have been identified as core Fynbos (Table Mountain), Fynbos refugia during interglacials (Kamiesberg). and an ecotonal region which might switch between the two biome types (Clanwilliam/ Niewoudtville). Presumably these three types of areas would provide interesting material for DNA-based phylogenetic work, and a test of the climate change 'species-pump' hypothesis proposed by Midgley et al. (2001).
Preliminary DNA fingerprinting of the turf grass Cynodon dactylon (Poaceae: Chloridoideae)
Authors: Roodt R. , Spies J. J. , Burger T. H.
Published: July 2015

Identification of different cultivars of turf grasses is often very difficult. In a preliminary attempt to identify different cultivars o f Cynodon dactylon (L.) Pers.. random amplified polymorphic DNA (RAPD) analyses of some well-known cultivars used in South Africa, i.e. Bayview. Cape Royal, Florida. Hamsmith. Silverton Blue. Skaapplaas and Titdwart. as well as 10 potential new cultivars, were done. These results were used to determine the genetic distances among cultivars. Only five primers w ere needed to obtain a specific fragment pattern for each cultivar. The degree o f amplification w as used as an additional criterion by including all visible fragments, excluding very faint fragments and only including the brightest fragments. The neighbour-joining trees o f C.  dactylon showed best resolution from the data set w ith all visible fragments included. although fragment intensity did not affect the tree topology. The cultivars Silverton Blue and Bayview exhibited the greatest genetic variation and two potential new cultivars were identified. RAPD analyses can. therefore, be used to distin­guish between different C. dactylon cultivars and to determine the genetic variation between them by calculating genetic distances.
