Typical Variety

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.

A New Species

Background: The Rhynchosia totta complex is one of three taxonomically complicated African groups in the genus Rhynchosia. Numerous southern African species and infraspecific taxa (at least 19 names, 17 species and 2 varieties) have been described by various authors in the past, but were later reduced into synonymy with  R. totta. Currently, only the typical variety is recognised in Southern Africa.Objectives:  To investigate and update the circumscription of the taxa within the  R. totta complex in southern Africa and to update their synonymies and distribution ranges. Methods: Specimens of R. totta at GRA, JRAU, K, NH and PRE were studied and compared, and measurements of characters recorded. Populations were also observed during field studies.Results: The examination of numerous specimens, as well as field investigations, has prompted the recognition of four varieties (one described here as new: R. totta var. longicalyx) and a new species (R. pedunculata) in southern Africa.Conclusions: A great variation in leaf structure and vestiture occurs within the R. totta complex, with the extreme forms easily recognisable. However, the total number of varieties are limited to four [R. totta vars. totta,  longicalyx,  rigidula and venulosa] and a new species described to accommodate specimens with a distinctly prostrate habit and upwardly directed leaves.

Breutelia microdonta (Mitt.) Broth., described originally from Brazil, is the oldest name for a disjunct widespread tropical species that includes as synonyms B. angustifolia Rehm. ex Sim of Southern Africa and B. merrillii Broth. of the Philippines. Breutelia kilaueae (C. Muell.) Broth. of Hawaii is considered a synonym of the austral Pacific species B. affinis (Hook.) Mitt., and B. brachyphylla Broth. of Ecuador is reduced to synonymy under the North Andean B. squarrosa Jaeg. Breutelia anacolioides Herz. of Bolivia is removed to Philonotis as a synonym of the North Andean P. incana (Tayl.) H. Robins. Differences in spore ornamentation offer an additional character distinguishing Breutelia from Philonotis.

African Genus

We describe eight new southern African species in the largely sub-Saharan African genus Moraea L., one from the winterdry Great Karoo and the others from the winter-rainfall zone of the southwest of the subcontinent. M. striata Goldblatt J.C.Manning (subg. Visciramosae Goldblatt) from the southern foothills of the Great Swartberg Mtns has khaki-green flowers with reflexed tepal limbs streaked with dark lines. The acaulescent M. singularis Goldblatt J.C.Manning (subg. Umbellatae Goldblatt J.C.Manning) with terete leaf blades is restricted to the dry, interior foothills of the Kamiesberg in Northern Cape. M. filamentosa Goldblatt J.C.Manning, subg. Acaules (Baker) Goldblatt J.C.Manning, is described from the dry interior of Namaqualand in Northern Cape. The species is closely allied to the widespread M. falcifolia Klatt. In subg. Polyanthes (Goldblatt) Goldblatt J.C.Manning, we describe M. thermarum Goldblatt J.C.Manning (sect. Hexaglottis (Vent.) Goldblatt) from southwestern Namibia, allied to M. brevituba (Goldblatt) Goldblatt, and M. lazulina Goldblatt J.C.Manning (sect. Pseudospicata Goldblatt J.C.Manning) from the Little Karoo, until now confused with M. exiliflora Goldblatt but differing in its larger flowers with strongly reflexed tepals. The new M. petricola Goldblatt J.C.Manning (subg. Vieusseuxia (D.Delaroche) Goldblatt), is restricted to higher elevations of the Pakhuis Mtns of northern Western Cape. Lastly, in subg. Homeria (Vent.) Goldblatt J.C.Manning, we recognize M. doleritica Goldblatt J.C.Manning with pale yellow flowers and anthers exceeding the style branches, restricted to dolerite outcrops in the Great Karoo, and M. eburnea Goldblatt J.C.Manning from the northern foothills of the Klein Swartberg, which has a single, basal leaf and pale yellow flowers with filaments free distally. Moraea now has 222 species, including 203 in southern Africa, of which 200 are endemic to the region. In addition to describing new species, the paper brings to light range extensions of a further eight species: M. barnardii L.Bolus, M. elliotii Baker, M. exiliflora Goldblatt, M. falcifolia Goldblatt J.C.Manning, M. fenestralis (Goldblatt E.G.H.Oliver) Goldblatt, M. louisabolusiae Goldblatt, M. tulbaghensis L.Bolus and M. unguiculata Ker Gawl. Each of the species falls into one of the subgenera mentioned for the new species except M. fenestralis which belongs in subg. Galaxia.

Another three new species of Riccia in section  Pilifer Volk are described from Namaqualand, namely  R. furfuracea, R vitrea and R. namaquensis. There are certainly more undescribed species present in that region, but species from there are often very difficult to distinguish: almost all have hyaline scales, the free-standing dorsal cell pillars need to be examined in living plants and the spore ornamentation is quite variable.

Sterile Lemma

The Setacea species group in the genus Ehrharta Thunb. is differentiated morphologically by the short first sterile lemma and by inflorescences of fewer than 20 spikelets. The Setacea group is composed of two species, each with subspecies linked by intraspecific intermediates: E. rupestris Nees ex Trin. subsp.  rupestris; subsp.  tricostata (Stapf) Gibbs Russell; subsp.  dodii (Stapf) Gibbs Russell and E. setacea Nees subsp.  setacea; subsp.  scabra (Stapf) Gibbs Russell; subsp. uniflora (Burch, ex Stapf) Gibbs Russell; subsp.  disticha Gibbs Russell. All taxa are endemic to the Fynbos vegetation of the south-western Cape Province, with distribution centred in the Caledon degree grid (3419). Parallel trends for plant size and habit, leaf blade width and position, and spikelet size are demonstrated in both species, with similar plant types occurring in similar geographical areas.

Two New Species

Two new species with spinose spores are described from the Western Cape.  F. elsieae Perold is quite a large plant, generally with almost entire leaves, its spores on the distal face having relatively few, rather coarse spines, which often appear broken and are occasionally linked to form abbreviated ridges.  F. spinosa Perold is a smallish plant with irregularly lobed leaves, its spores on the distal face having numerous, fine spines, which sometimes coalesce to form short ridges. A table which com­pares F. glenii Perold,  F. leucoxantha Lehm. and F. montaguensis S.W.Arnell with the two new species, is supplied.

Two New Species

The native and naturalized species of Silene L. in southern Africa are reviewed, with full synonomy and the description of two new species from the West Coast of Western Cape. Eight native species and three naturalized species are recognized, including the first identification in southern Africa of the Mediterranean S. nocturna L. The identity of S. aethiopica Burm., which has remained unknown since its description, is established and is found to be the oldest name for S. clandestina Jacq. Patterns of morphological variation within each species are discussed and subspecies are recognized for geographically segregated groups of populations that are ± morphologically diagnosable. The following new names or combinations are made among the southern African taxa: S. aethiopica subsp. longiflora; S. burchellii subsp. modesta, subsp. multiflora, and subsp. pilosellifolia; S. crassifolia subsp. primuliflora; S. saldanhensis; S. rigens; and S. undulata subsp. polyantha. Each taxon is described, with information on ecology and distribution, and most species are illustrated, including SEM micrographs of the seeds.

Cololejeunea cardiocarpa was misidentified by Arnell (1963) and described by him as a new variety, Leptocolea cristata var.  lanciloba. Gradstein  et al. (1983) drew attention to this error. Fresh material has now been collected and the species is described here and illustrated with photographs.
