African Genus

A member of Iridaceae subfamily Crocoideae. Babiana Ker Gawl. comprises some 80 species from southern Africa. Field studies have shown the need for several taxonomic and nomenclatural changes, while a number of new species have been discovered. The type of B flabellifolia Harv. ex Klatt is a short-tubed plant that matches B. truncata GJ.Lewis. and that name falls into synonymy. The name B. flabellifolia sensu GJ.Lewis (1959) has been misapplied to long-tubed plants from the western Karoo which are now renamed B. praemorsa sp. nov. In addition. B. truncata, as originally circumscribed, included two species, one short-tubed and a second with a longer tube, which we describe here as B. cuneata sp. nov. The type off?  hypogaea Burch, has also been misinterpreted and matches the species described as B.flavida. which thus falls into the synonymy of B hypogaea. A second species. B.falcata GJ.Lewis. closely matches this species and is also reduced to synonymy. The widespread southern African species long known as B hypogaea (hypogea sensu GJ.Lewis) matches the type ol  B. bainesii Baker and must now be known by that name. Babiana stricta var.  erectifolia (GJ.Lewis) GJ.Lewis is appropriately included in typical B. stricta (Aiton) Ker Gawl. However, var. regia GJ.Lewis is a very different plant and is treated as a separate species. B. regia comb, et stat. nov.. as is long-tubed var. grandiflora GJ.Lewis. which is described as the new species, B. longiflora sp. nov. Plants included in B. stricta var. sulphurea sensu GJ.Lewis are also included in var. stricta. We are unable to match the type of Gladiolus sulphureus Jacq.. basionym of var. sulphurea (Jacq.) Baker, with any known species and the name is thus excluded. Lastly, the name B. disticha Ker Gaw l., type of the genus, is superfluous for Gladiolus fragrans Jacq. and the new combination  B fragrans comb. nov. is made, reducing  B. disticha to synonymy. Babiana fragrans Eckl., which was thought to prevent the transfer of G. fragrans. is a nomen nudum and thus invalid and cannot be taken into account in considerations of nomenclatural priority.

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.

Three New Species

Field studies of the sub-Saharan African and largely southern African Hesperantha conducted since 2003 have resulted in the discovery of three new species in this genus, bringing the total to 82. Hesperantha longistyla J.C.Manning Goldblatt. known from one collection from the mountains of SW Namibia, is a dwarf plant with moderately long-tubed, purple flowers and unusually long style branches, possibly allied to the Kamiesberg species,  H. latifolia. A second species,  H. helmei Goldblatt J.C.Manning, also known from a single collection from the interior mountains of Eastern Cape near Graaff- Reinet, has terete leaves and small flowers with tepals ± 8 x 2.5 mm, about as long as the perianth tube. It is apparently most closely allied to the Roggeveld species, H. cliolata. A third novelty, H. lithicola J.C.Manning Goldblatt. restricted to the Swartruggens range in the eastern Cold Bokkeveld, has bell-shaped corms with toothed margins, leaves 1-2 mm wide, and white flowers with a tube 10-12 mm long, and appears most closely allied to the widespread H. falcata. A new collection of H karooica from northeast of the Hantamsberg represents a small but significant range extension for this local endemic previously known from just two collections near Calvinia, south of these mountains. The flower size, especially dimensions of the tepals, confirms its status as a separate species allied to H. vaginata. Lastly, new collections o f the relatively uncommon, yellow-flowered variant of H. acuta show that this plant, confined to the eastem portion of the range of the species, differs consistently from the white-flowered form in several floral features, and it is raised to subspecies rank as H. acuta subsp.  tugwelliae.

Twelve new species in a new genus, Geelus gen.n. are described, 10 species from a confined area in the north- and south-western parts of South Africa and two from Namibia. The genus has been recorded from 35 plant species in 18 families, with one species Geelus dundraad collected on Rooibos Tea, Aspalathus linearis (Fabaceae), which is indigenous to South Africa and cultivated commercially. The 12 new species are Geelus driehoekdraad sp.n., G. drietanddraad sp.n., G. dundraad sp.n., G. haakdraad sp.n., G. kinkeldraad sp.n., G. lemdraad sp.n., G. nektanddraad sp.n., G. platdraad sp.n., G. slangdraad sp.n., G. stompdraad sp.n., G. viertanddraad and G. vurkdraad sp.n. This new genus is allied to the Bonaspeiini, in the Deltocephalinae based on the broad lorum, apically expanded clypellus, dorsal side of the pygofer deeply and broadly incised, large sclerotized segment X, smooth merging of face and crown and Y-shaped connective with short stem. A MaxEnt distribution model based on 19 bioclimatic variables confirmed that the South African species occur within a confined region in the south-western parts of southern Africa.

A New Species

Gymnosporia swazica, a new restricted-range southern African species, is described and illustrated here. Known from only a few localities in Swaziland and bordering parts of South Africa (Mpumalanga and northeastern KwaZulu-Natal), G. swazica grows as an understorey shrub or small tree in forest, often among granite boulders. Diagnostic characters for G. swazica include chartaceous leaves, usually shorter than 25 mm, 3-valved capsules usually 6–7 mm long, which are smooth, green turning yellow, and a white aril partially covering the brownish seed. Its closest relative appears to be G. buxifolia (capsules rugose, mottled white-and-brown), one of the most widespread members of the genus in southern Africa, but it can also be confused with G. maranguensis (capsules red, 2-valved) and G. harveyana (capsules pink to red, 3-valved; aril orange, completely covering the seed).

A New Species

A new species of vestimentiferan tubeworm belonging to the genus Escarpia is described from cold seeps off the western coast of Africa. The description is based on two collections (one of 180 animals, the other of 30 animals) using both morphological and molecular techniques. Morphologically, the African tubeworms are very similar to Escarpia laminata Jones, 1985 but differ from all other escarpids by the lack of branchial pinnules, a unique feature among vestimentiferans. Molecular evidence from sequences of the cytochrome-c oxidase subunit I gene places the species in the escarpid clade, closely related to E. laminata and Escarpia spicata Jones, 1985, but fails to discriminate among the three species. Four morphotypes are identified in the African species, corresponding to the four permutations of the following characters: presence or absence of an axial rod on the obturaculum and presence or absence of a split on the posterior ventral margin of the vestimentum. However, molecular data could not distinguish them as separate species. We suggest that the lack of an axial rod reflects predation. Biometrical data indicate a discontinuous recruitment period, as is known for other vestimentiferan species. Sex ratios are balanced, but females tend to be larger than males. We hypothesize that the males grow more slowly or die younger than the females.

Field studies have provided an improved understanding of a known undescribed species of Tricoryne R.Br. and also shown that two or three separate species are included in an existing taxonomic concept. Two new species are described here, namely, T. tuberosa Keighery & T.D.Macfarl. and T. soullierae T.D.Macfarl. & Keighery. Tricoryne tuberosa has an extensive range in the northern wheatbelt and adjacent pastoral areas of south-western Western Australia. It has large root tubers, the leaves are withered at flowering time, and it forms clonal groups by long rhizomatous shoots. Tricoryne soullierae has a restricted distribution in remnant vegetation in the northern wheatbelt. It has fibrous roots and is conspicuously leafy when flowering.

African Genus

The genus Iselma belongs to the most basal subfamily Eleticinae and it is strictly distributed in the western portion of southern Africa. The taxonomy of this group was previously treated, but it is still incomplete and unclear. In this contribution we clarified some taxonomic misinterpretations and we describe nine new species: I. audisioi sp. n., I. cedarbergensis sp. n., I. elephantula sp. n., I. fontisamarae sp. n., I. kamanjabi sp. n., I. kaszabi sp. n., I. lorenzettii sp. n., I. mimica sp. n., I. stellaris sp. n.. The following new synonymies are proposed: I. analis Kaszab, 1953 = I. simillima Kaszab, 1953; I. hirsuta (Thunberg, 1791) = I. ursus (Thunberg, 1791). This taxonomic improvement required the proposal of a new updated key to the species. New faunistic records for several species are also included, and the phenomenon of extreme endemicity in this genus is highlighted.

Six species of the mainly tropical genus Emilia (Asteraceae, Senecioneae) occur in southern Africa. These species are generally not well known as no revision of the genus on a global scale has as yet been undertaken and previous work has focussed on eastern, central and northern Africa. A new combination, Emilia schinzii (syn. E. ambifaria), is proposed here because of priority. Detailed descriptions, distribution maps and a key to the southern African species are presented in this synopsis. Lectotypifications for E. limosa, E. marlothiana, E. schinzii and E. transvaalensis are provided. Included is information relevant to conservation of the species in the form of red data assessments and notes.

During recent decades, Althenia with two species in Eurasia and Africa was accepted as one of four genera of submerged aquatics comprising the family Zannichelliaceae. Molecular phylogenetic data confirmed monophyly of Zannichelliaceae in its traditional circumscription but placed the clade together with Potamogeton and its segregate genera, so that Zannichelliaceae is currently placed in synonymy of Potamogetonaceae. Recent molecular data demonstrated that Eurasian and African species traditionally placed in Althenia s.str. are nested within the Australasian (Australia and New Zealand) Lepilaena. As a result, the two genera were combined under the name Althenia s.l. The present study describes a new species, A. hearnii T. Macfarlane & D.D. Sokoloff from southwestern Western Australia which fills a morphological gap between species traditionally placed in Althenia s.str. and Lepilaena, thus supporting molecular phylogenetic evidence for lumping the two genera. The new species has a polysymmetric circular stigma like Althenia s.str. but 12-sporangiate anther like most species traditionally classified in Lepilaena. Like some other Australian species, Althenia hearnii is dioecious with dimorphic male and female inflorescences. The dimorphism includes the presence of a ligule in leaves within male inflorescences and the absence of a ligule in leaves within female inflorescences as well as strong differences in internode length between male and female inflorescences. A new combination Althenia patentifolia (E.L. Robertson) T. Macfarlane & D.D. Sokoloff is also made in order to allow Althenia to be fully applied in Australia. A revised key to the species of Althenia is provided.
