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 are described in the largely sub-Saharan genus Moraea Mill. (± 200 spp.), all from its centre of diversity in the winter rainfall region of southern Africa. Moraea pearsonii, from Hottentotskloof near Ceres in Western Cape, flowers in late November and December when its leaves are ± dry, and has small, pale lilac, stellate flowers with the style branches each divided to the base into filiform arms.  Moraea tanquana, from the Tankwa River Basin in Northern Cape, resembles the southern Namaqualand M. deserticola but has broad, plane leaves, short anthers exserted from a shallower floral cup and a short style. In section Acaules, M. longipes from Namaqualand stands out in its early flowering habit, a stem consisting of a single long intemode reaching well above the ground, short style and unusually long anthers. Moraea jarmilae described from Ox Bow, Lesotho in 2002, is conspecific with M. albicuspa and is reduced to synonymy. Significant range extensions are reported for M. elsiae, M. falcifolia, M. pseudospicata, M. spathulata, M. tricolor, M. vegeta, M. verecunda, M. vespertina and M. vlokii. A yellow-flowered morph, local in the Perdebont Valley of the Little Karoo, is reported for the first time in typically blue- to violet-flowered M. bipartita, as well as the occurrence of a hybrid swarm, rare in Moraea, between M. bipartita and M. polyanthos.

Babiana rivulicola from stream banks in the Kamiesberg in Namaqualand and terete-leaved Ixia teretifolia from the Roggeveld, both in Northern Cape, are new species of these two largely winter-rainfall region genera. Late-flowering populations of Hesperantha radiata with crowded spikes of smaller flowers are segregated from the typical form as subsp. caricina. We also document the first record of B. gariepensis from Namibia, correct the authority for B. purpurea Ker Gawl., discuss morphologically aberrant populations of B. tubiflora from Saldanha, provide an expanded description for B. lapeirousiodes based on the second and only precisely localized collection of this rare Namaqualand species, and expand the circumscription of Geissorhiza demissa to accommodate a new record from the Kamiesberg, including revised couplets to the existing key to the species.

We describe a new species in the sub-Saharan genus Ornithoglossum Salisb. from southern Namibia. Ornithoglossum pulchrum from near Aus, is remarkable in having bright to dark pink flowers, a feature previously unknown in the genus. The perigone is almost concolorous apart from a contrasting, pale yellow nectary region, narrowly outlined with darker red, near the base of each tepal. The undulate leaves together with the long filaments, which are nearly as long as the tepals, suggest a relationship with O. undulatum, a widespread species in the western parts of southern Africa, and O. zeyheri from Namaqualand and the northwestern Cape.

The southern African species of the water beetle genus Ochthebius Leach, 1815, are reviewed. Eight new species are described, and new collection records are given for eight previously described species, based on the examination and databasing of 8,919 specimens from 253 localities/events. Male genitalia of the new species are illustrated, and high resolution habitus images of the holotypes of new species are provided. Distribution maps are given for the 18 species of Ochthebius now known from southern Africa, including Namibia, South Africa, Lesotho, Zimbabwe, the extreme southern part of Angola, and the southern part of Mozambique. New species of Ochthebius are: O. anchorus (South Africa, KwaZulu-Natal Province, Oribi Gorge); O. bicomicus (South Africa, Western Cape Province, 22 mi. N. Nelspoort); O. bupunctus (Namibia, Kaokoveld, Kunene River, Swartbooisdrift); O. endroedyi (South Africa, North West Province, Barberspan); O. granulinus (South Africa, Western Cape Province, Elandsdrift); O. involatus (South Africa, Western Cape Province, near Kommetje); O. sitiensis (Namibia, Okau Fountain, 12.5 km inland); and O. zulu (South Africa, KwaZulu-Natal Province, Nqutu).

Detailed Assessment

Acanthopsis is a taxonomically poorly understood genus confined to arid parts of southern Africa. This contribution is the first detailed assessment of the diversity within the Acanthopsis disperma-hoffmannseggiana complex, the latter of which comprises the bulk of the specimens of the genus represented in herbaria. Species concepts are resolved and the misapplication of names is noted. In addition to the recognition of A. disperma and A. hoffmannseggiana, five new species of Acanthopsis formerly treated under these two names, are described, namely A. tuba and A. ludoviciana (both confined to the Richtersveld, Northern Cape, South Africa), A. adamanticola (endemic to southern Namibia), A. villosa (endemic to Bushmanland, Northern Cape) and A. dispermoides (endemic to the Western Cape, South Africa). The names A. disperma and A. hoffmannseggiana are lectotypified here. An identification key to the members of the Acanthopsis disperma-hoffmannseggiana complex is provided, as well as an interim key to the major artificial groupings in the genus, the taxonomy of some which still needs to be resolved.

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.
