Authors: Schutte A. L.
Published: July 2015

Literature on the hyphomycete genus Penicillium Link and its teleomorphs, Eupenicillium Ludwig and  Talaromyces C.R.Benjamin, is surveyed in the Republic of South Africa, Lesotho, Mozambique, Namibia, Swaziland and Transkei up to 1990. References are grouped under the headings, general mycology, plant pathology, industrial application, medical importance, mycotoxins and chemical work. An alphabetical list of the species recorded in southern Africa as well as the host and/or substrate from which each species has been reported is presented with relevant literature references; specimens in various culture collections are also incorporated. Although most of the known Penicillium species have already been reported from southern Africa, in-depth work is still required in all fields of research concerning this genus.

NOTES ON THE GENUS  STREPTOCARPUS
A phytosociological study of Signal Hill, Cape Town, utilizing both perennial and ephemeral species
Authors: Joubert C. , Moll E. J.
Published: July 2015

A phytosociological study based on the collection of vegetation and environmental data from 53 randomly stratified sample plots on Signal Hill, Cape Town, was carried out over an area of 124 ha. The survey extended over 12 months to ensure the inclusion of as many plant species as possible, and a list of the vascular plant species was compiled. A total of 81 families, 255 genera and 460 species was identified. The phytosociological method revealed that only one major plant community occurs in the study area and two subcommunities, with a total of five variants correlated mostly with aspect and historic land use, were identified. The perennially and seasonally identifiable species were analysed separately to determine their relative contribution to the phytosociological classification. The two data sets gave similar classifications. A vegetation map as well as a soil map was compiled.

The vegetation of the southern Langeberg, Cape Province. 1. The plant communities of the Boosmansbos Wilderness Area
Authors: Mcdonald D. J
Published: July 2015

An analysis of the fynbos shrublands and forests of the Boosmansbos Wilderness Area, southern Langeberg, Cape Province, South Africa, is presented. Data were collected at 119 sites in mature fynbos vegetation (10 years old) and at five sites in patches of Afromontane Forest. Emphasis was placed on the fynbos shrublands and sample sites were subjectively located along a transect from south to north across the Langeberg range in the study area. This south to north orientation follows a complex gradient of changes in aspect, slope, geology, soil form and climate. Data were initially analysed using TWINSPAN and the resulting classification refined using Braun-Blanquet procedures. One forest subassociation and 12 fynbos communities were identified and described. A proposed hierarchical classification of the fynbos communities is presented.

The efficient use of small plots in a fynbos phytosociological study in the northern Cederberg: a quick way to collect plant-environmental data
Authors: Mustart P. J. , Moll E. J. , Taylor H. C.
Published: July 2015

A phytosociological survey of selected plant communities in the northern Cederberg was made using small (4-16 m') plot sizes. A satisfactory phytosociological table was obtained, and plant-environmental relationships were inferred from it. The use of small plot sizes enabled ecological information about plant communities to be quickly, easily and efficiently obtained. This method could be of considerable use for establishing and monitoring vegetation patterns.
Plant defences against mammalian herbivores: are juvenile Acacia more heavily defended than mature trees?
Authors: Brooks R. , Owen-Smith N.
Published: July 2015

Juvenile trees are expected to be more heavily defended against browsing mammals than mature plants. Juvenile and mature trees of Acacia tortilis and A. nilotica occurring at Nylsvley, Northern Transvaal, were quantitatively compared in terms of some potential chemical and physical defences. Neither species showed any significant difference between juvenile and mature trees in terms o f total polyphenol content, condensed tannin content, protein precipitating ability or protein content in leaves. Both species showed age-class differences in spinescence. In A. nilotica, thorns on branch tips were longer and more closely spaced and leaves were smaller in juveniles than in adults. Hence juveniles of this species appear to be physically more heavily defended than mature plants. In A. tortilis, curved thorns were longer, but straight thorns were shorter than in mature trees. There was no difference between age classes in overall thorn density, but juveniles had a higher curved to straight thorn ratio. It is not obvious what the effects of these differences might be on mammalian browsers.

An annotated list of Urediniomycetes (rust fungi) from South Africa 1: Melampsoraceae and Pucciniaceae, excluding Puccinia and Uromyces
Authors: Van Reenen M.
Published: July 2015

Up-to-date information is given on the identity, occurrence, nomenclature, host ranges, geographical distribution and literature references of the Urediniomycetes in South Africa. Species of the family Melampsoraceae and all species of the family Pucciniaceae other than those in the genera Puccinia Pers. and  Uromyces (Link) Unger are listed. New species records since 1945 include the following:  Melampsora allii-populirui Kleb..  Melampsora coleosporioides Dietel.  Melampsora laricipopulina Kleb.. Melampsora medusae Thiim., Frommea obtusa-duchesneae (Arthur) Arthur. Hemileia gardeniae-thunbergiae Maubl. Roger.  Phakopsora gossypii (Arthur) Hirats. F. Uromycladium tepperianum (Sacc.) McAlpine and  Tranzschelia discolor (Fuckel) Tranzschel M.A. Litv. Although many species of rusts have already been recorded, these are thought to represent only a small percentage of the rust population in southern Africa. Furthermore, only a small portion of rust specimens at present housed at PREM have so far been studied. Continued research on this economically important group of fungi is therefore essential.

Comparative field performance of three different gas exchange systems
Authors: Midgley G. F. , Veste M. , Don Willert D. J. , Davis G. W. , Steinberg M. , Powrie L. W.
Published: July 2015

We compared portable and continuously monitoring gas exchange systems under field conditions, using Protea glabra Thunb. as a test species. The aim was to determine if the same patterns of gas exchange and ancillary parameters could be obtained with rather different measurement systems, and whether the same interpretation and conclusions about environmental control of gas exchange could be drawn. The following systems were compared: 1, a ‘closed’ portable 1RGA manufactured by Ll-Cor (LI-6200); 2, an ‘open’ portable porometer manufactured by Walz; and 3, a continuously monitoring minicuvette system with temperature control facility, also manufactured by Walz. All three systems yielded similar diurnal curves for CO2  uptake, although absolute flux values for the minicuvette system were lower than those obtained for the portable systems. This was likely due to stem respiration and self-shading of leaves on the shoot enclosed in the minicuvette. Differences in sampling technique between the two portable systems, primarily with regard to changes in leaf orientation, resulted in some differences in absolute values of gas fluxes and ancillary parameters such as leaf temperature and leaf to air vapour pressure difference. However, data from all three systems allowed similar interpretations to be made about the environmental dependencies of gas exchange patterns. It appears that each system has certain drawbacks associated with widely varying field conditions. A combination of portable and continuous monitoring techniques would seem to be the most powerful approach to investigating the gas exchange patterns of terrestrial plants in their natural environment.

Wetland plant communities in the Potchefstroom Municipal Area, North-West, South Africa
Authors: Cilliers S. S. , Schoeman L. L. , Bredenkamp G. J.
Published: July 2015

Wetlands in natural areas in South Africa have been described before, but no literature exists concerning the phyto­sociology of urban wetlands. The objective of this study was to conduct a complete vegetation analysis of the wetlands in the Potchefstroom Municipal Area. Using a numerical classification technique (TWINSPAN) as a first approximation, the classification was refined by using Braun-Blanquet procedures. The result is a phytosociological table from which a number of unique plant communities are recognised. These urban wetlands are characterised by a high species diversity, which is unusual for wetlands. Reasons for the high species diversity could be the different types of disturbances occurring in this area. Results of this study can be used to construact more sensible management practises for these wetlands.

Comprising an area of ± 90 000 km:, less than 5% of the land surface of the southern African subcontinent, the Cape Floristic Region (CFR) is one of the world’s richest areas for plant species diversity. A recent synoptic flora for the Region has established a new base line for an accurate assessment of the flora. Here we document corrections and additions to the flora at family, genus and species ranks. As treated in Cape plants, which was completed in 1999. the flora comprised 173 families (five endemic), 988 genera (160 endemic: 16.2%), and 9 004 species (6 192 endemic: 68.8%). Just four years later, a revised count resulting from changes in the circumscriptions of families and genera, and the discovery of new species or range extensions of species, yields an estimate of 172 families (four endemic), 992 genera (162 endemic: 16.3%) and 9 086 species (6 226: 68.5% endemic). Of these, 948 genera and 8 971 species are seed plants. The number of species packed into so small an area is remarkable for the temperate zone and compares favourably with species richness for areas of compa­rable size in the wet tropics. The degree of endemism is also remarkable for a continental area. An unusual family compo­sition includes, in descending order of size, based on species number. Asteraceae. Fabaceae. Iridaceae. Ericaceae. Aizoaceae, Scrophulariaceae. Proteaceae. Restionaceae, Rutaceae. and Orchidaceae. Disproportionate radiation has resulted in 59.1% of the species falling in the 10 largest families and 74.6% in the largest 20 families. Thirteen genera have more than 100 species and the 20 largest genera contribute some 31.5% of the total species number.

Ovule and seed structure in Scolopia zeyheri (Scolopieae), with notes on the embryology of Salicaceae
Authors: Steyn E. M. A. , Van Wyk A. E. , Smith G. F.
Published: July 2015

Scolopia zeyheri (Nees) Harv. is a widespread African tree and a member of the largest genus of the tropical Old World tribe Scolopieae (Salicaceae sensu lato). This light microscopic study is the first report on ovule and seed structure in the genus and the tribe. Ovules vary from four to six per ovary, are anatropous. crassinucellate. bitegmic and occur in an epitropous (rarely pleurotropous). median-parietal position in the unilocular, usually bicarpellate ovary. A very extensive nucellus cap. comprising nucellus epidermal derivatives and parietal tissue, characterizes the young ovule during mega- sporogenesis and megagametogenesis, but the chalazal nucellus is poorly developed. During meiosis. the micropvlar dyad cell degenerates early. The functional dyad cell forms two megaspores of which the chalazal one usually develops into a Polygonum-type embryo sac. At maturity, the micropylar end of the embryo sac is covered by the remnants of the nucellus epidermis, the parietal tissue having degenerated. The globular embryo has a short suspensor and lies in nuclear endosperm becoming cellular. The seed coat develops from both integuments, is tannimferous. has a glabrous surface with stomata and a single layer of exotegmic, longitudinal fibres.Results are compared with relevant information previously reported for genera in the tribes Flacourtieae. Samvdeae. Saliceae, Scyphostegiae and for Oncoha Forssk. (Salicaceae sensu lato). Embryologically Scolopia shows a number of ple- siomorphic features compared to other Salicaceae. For example, it lacks an extranucellar embryo sac. an apomorphic fea­ture in many Salicaceae. A summary of ovule and seed characters in Salicaceae sensu lato is given and contrasted with data available for Achariaceae  sensu lato. Embryological data broadly supports the reclassification of genera, traditionally referred to Flacourtiaceae. amongst Salicaceae sensu lato and Achariaceae sensu lato.

Two new species of Commiphora (Burseraceae) from southern Africa
Authors: Swanepoel W.
Published: July 2015

Commiphora steynii Swanepoel and C.  gariepensis Swanepoel, here described as new species, are known only from the Kaokoveld and Gariep Centres of Endemism respectively. Illustrations of the plants and distribution maps are provided. Diagnostic characters of C.  steynii include the pale ashy grey, non-peeling bark and the lack of wart-like projections around the large lenticels. Diagnostic characters of C. gariepensis include the stamen number which varies between four and eight, and the milky-watery latex which does not squirt when branches are damaged. When without leaves or fruit, C. gariepensis can easily be confused with several other species. Comprehensive tables with diagnostic morphological features to distinguish between the new species and closely related taxa are presented.
Reappraisal and identification of Olinia rochetiana (Oliniaceae) in South Africa
Authors: Sebola R. J. , Balkwill K.
Published: July 2015

A numerical phenetic analysis of data obtained from populations of the Olinia rochetiana A.Juss. complex occurring in South Africa (Mpumalanga and Limpopo Provinces) revealed the existence of two forms: 1, a shrubby form (up to 2.5 m tall), with thick terminal branches, coriaceous leaves with a tinge of red on margins (towards the apices),short inflorescence axes, peduncles and deeply red pedicels and floral tubes/hypanthia: and 2, a slender tree form, measuring more than 4 m tall with slender terminal branches, glossy and slightly thin, papery leaves, margin colour the same as the entire lamina, and the inflor­escence axes, peduncles, pedicels and hypanthia pale green to creamy white. Differences in floral features between the twoforms correlate with differences observed in vegetative features. The two forms occupy distinct ecological niches and show tolerances and preferences for different environmental conditions such as soil type,elevation and humidity. An identificationkey for the two forms is presented.

A checklist of the trees, shrubs and Hanes of Catapú, Cheringoma District, Mozambique, is presented. Floristically the study area falls within the Swahilian/Maputaland Regional Transition Zone. In total, 238 woody species and infraspecific taxa have been recorded, representing 59 families and 167 genera. Most species (64%) occur both to the north and south of the study area. 26% have their core distribution in the Swahilian Regional Centre of Endemism, 4% have a more southerly distribution. 14 are endemic to the Swahilian/Maputaland Regional Transition Zone and two near-endemic, extending into the Zambezian Regional Centre of Endemism only along the Zambezi River Valley as far west as Kariba. The checklist includes the Sena names for 191 species, 77 of which are recorded for the first time. Comparisons of the Catapú checklist are made with other checklists.
The concept of ’Musa-pelo and the medicinal use of shrubby legumes (Fabaceae) in Lesotho
Authors: Moteetee A. , Van Wyk B-E.
Published: July 2015

In the Kingdom of Lesotho, 20 plant species are commonly known as  'Musa-pelo. The term literally means ‘the one who brings back or tums around the heart’.  'Musa-pelo is traditionally used as a sedative and is given as a first aid treatment to bereaved people who are under severe psychological duress or stress. Of the 20 species known as  'Musa-pelo, 17 belong to nine genera of the Fabaceae  (Argyrolobium, Crotalaria, Indigofera, Lessertia, Lotononis, Melolobium, Sutherlandia, Tephrosia and  Trifolium). The three remaining species namely Cleome monophylla, Heliophila carnosa and  Cysticapnos pruinosa, belong to the families Capparaceae, Brassicaceae and Fumariaceae, respectively. In this paper, the concept of 'Musa-pelo in traditional medicine is explored.
Threatened Limestone Fynbos plant communities of Andrew’s Field and Tsaba-Tsaba Nature Reserve, Western Cape
Authors: Zietsman M. M. , Bredenkamp G. J.
Published: July 2015

The vegetation of inland plains and hills of the Andrew’s Field and Tsaba-Tsaba Nature Reserve, Bredasdorp District, Western Cape was classified using TWINSPAN and Braun-Blanquet procedures. The resulting four plant communities and nine subcommunities were described and interpreted ecologically. The vegetation was sampled using 97 randomly stratified plots. The floristic composition, Braun-Blanquet cover-abundance of each species, and various environmental variables were recorded in each sample plot. The relationship between the vegetation units and the associated environmental gradients was confirmed by ordination, using the DECORANA computer program, applied to the floristic data set. The conservation priority of each vegetation unit was determined by taking the occurrence of Red Data List species, limestone endemic species and Cape Floristic Region endemic species into consideration. TTie distribution of the plant communities can mainly be ascribed to differences in the clay/sand content of the soil and the degree of exposure of the vegetation to the dominating winds (southeastern and northwestern) of the area.
A revision of Ornithogalum subgenus Aspasia section Aspasia, the chincherinchees (Hyacinthaceae)
Authors: Manning J. C. , Martínez-Azorín M. , Crespo M. B.
Published: July 2015

The species of Ornithogalum L. subgenus Aspasia section Aspasia are revised. Section Aspasia is defined by a rosette of  lanceolate to oblong leaves; large, boat-shaped, ± petaloid bracts; moderately-sized white, yellow or orange flowers, sometimes with dark central markings; thin-textured, ellipsoid capsules that are enclosed by and concealed within the persistent, papery perianth; and angular, colliculate to echinulate seeds. Twelve species are recognized in the section, separable into three series based on seed morphology. O. conicum is redefined to exclude specimens from the Eastern Cape, which are recognized as O. synanthifolium, and O. conicum subsp.  strictum is raised to species status as O. strictum. The circumscription of O. duhium is expanded to include O.fimbrimarginatum and O. subcoriaceum, previously distinguished on account of their longer styles.Collections from the Roggeveld Escarpment and Klein Roggeveld that were previously included in O. fimbrimaiginatum are recognized as the new species O. corticatum Mart.-Azarin, on the basis of their unusual, thick, cartilaginous outer tunics and puberulous adaxial leaf surface. O. ceresianum is removed from the synonomy of O. thyrsoides and recognized as a distinct species on account of its extensive glossy black tepal markings, winged inner filaments, and glossy black ovary. The poorly known  O. puberuhim is more ftilly described based on several recent collections, and  O. leeupoortense is neotypified in the absence of any original type material.  O. rupestre and O. multifolium are regarded as colour forms of the same species, for which  O. rupestre is the older name. Similarly, O. roussouwii is a depauperate, pale form of O. maculatum and is thus included in the synonomy of that species. The circumscription of O. pruinosum remains unchanged. The species O. haurii, O. diphyllum and O. sephtonii from the Drakensberg Mountains of Eastern Cape and KwaZulu-Natal are excluded from section Aspasia on the basis of their turbinate capsules that are exposed by the reflexed tepals. Each species is fully described, with accompanying discussion of variation and relationships, a distribution map, and an illustration.
Invasive, naturalized and casual alien plants in southern Africa: a sum­mary based on the Southern African Plant Invaders Atlas (SAPIA)
Authors: Henderson L.
Published: July 2015

The primary objective of this publication is to provide an overview of the species identity, invasion status, geographical extent, and abundance of alien plants in South Africa, Swaziland and Lesotho, based on field records from 1979 to the end of 2000. The dataset is all the species records for the study area in the Southern African Plant Invaders Atlas (SAPIA) database during this time period. A total of 548 naturalized and casual alien plant species were catalogued and invasion was recorded almost throughout the study area. Most invasion, in terms of both species numbers and total species abundance, was recorded along the southern, southwestern and eastern coastal belts and in the adjacent interior. This area includes the whole of the Fynbos and Forest Biomes, and the moister eastern parts of the Grassland and Savanna Biomes. This study reinforces previous studies that the Fynbos Biome is the most extensively invaded vegetation type in South Africa but it also shows that parts of Savanna and Grassland are as heavily invaded as parts of the Fynbos. The Fabaceae is prominent in all biomes and Acacia with 17 listed species, accounts for a very large proportion of all invasion. Acacia mearmii was by far the most prominent invasive species in the study area, followed by A. saligna, Lantana camara, A. cyclops, Opuntia ficus-indica. Solarium mauritianum, Populus alba/xcanescens, Melia azedarach, A. dealbata and species of Prosopis.

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

This regional taxonomic revision of the genus  Wellstedia  Balf.f., a member of the family Boraginaceae  s.I. (including Hydrophyllaceae s.str.), is part of a series of publications on the Boraginaceae in southern Africa.  Wellstedia comprises six species, five in Socotra, Somalia and Ethiopia with the remaining one.  W. dinteri Pilg.. occurring in southern Africa.  W dinteri Pilg. subsp. dinteri occurs in Namibia and the Northern Cape, whereas the newly instated subspecies W. dinteri subsp. gracilior (D.R.Hunt) Retief A.E.van Wyk, based on W. dinteri Pilg. var. gracilior D.R.Hunt, is confined to Namibia only. The disjunct distribution of Wellstedia and numerous other plant and animal taxa between the arid regions of northeastern Africa and southern Africa is usually explained by the postulated periodic existence of an arid corridor between the two regions during the arid phases of the Pleistocene and even earlier.  Wellstedia is treated here in Wellstedioideae, a subfamily of Boraginaceae s.I. but is sometimes placed in a family of its own, Wellstediaceae Pilger. Morphologically Wellstedia displays strong similarity to genera of the Ehretioideae and also to certain members of the Hydrophyllaceae. The genus is characterized by a perennial, dwarf shrub habit, densely hairy leaves. 4-merous flowers, a terminal, bifid style and a 1- or 2-seeded capsule. A key to the two subspecies, diagnostic characters, a distribution map and illustrations of various macro- and micromorphological features are provided.

Vegetation and vegetation-environment relationships at Grootbos Nature Reserve, Western Cape, South Africa
Authors: Mergili M. , Privett S.
Published: July 2015

The private Grootbos Nature Reserve is located at the Western edge of the Agulhas Plain in the Cape Floristic Region of South Africa, an area characterized by high habitat and floristic diversity. The Reserve is covered in near-natural fynbos shrublands with a few patches of forest and wetland. The main objective of this study was to classify the vegetation into discrete units and relate them to the prevailing environmental conditions. The vegetation was analysed by numerical means (TWINSPAN, DC A, CCA) and mapped on GIS. At the vegetation type level. Forest Thicket and Fynbos formed distinctive clusters, whereas the wetland releves were intermixed, but without relationships to one of these units. Fire incidence served as the major determinant of the forest-fynbos boundary. The Forest Thicket grouping was separated into Thicket (as transitional to fynbos), Afromontane Forest and Milkwood Scrub Forest. Two broad complexes were distinguished within the Fynbos grouping, the Alkaline Sand Fynbos Complex corresponding to Coastal Fynbos. and the Acid Sand Fynbos Complex corresponding to Mountain Fynbos. They discriminated along gradients of pH. soil depth and rock cover. The complexes were further subdivided into formations by using one or a few subjectively chosen dominant species as indicators. The transitions between these formations were rather continuous than discrete. The vegetation type and complex levels correspond well to existing fynbos-wide classifications. Comparing the formations to the results of other vegetation studies is problematic even on the scale of the Agulhas Plain, due to the high regional plant diversity in the Fynbos Biome.
