Pelargonium hammansbergense and P. roseopetalum are described as new species. Both are deciduous geophytes with turnip-shaped tubers belonging to P. section Hoarea. These two species share spathulate petals with narrow cuneate claws.  However, they differ in leaf shape, flower colour and markings on the petals. Their flower structure corresponds to that of P. aridicola, P. hirtipetalum, P. pubipetalum, P. reflexipetalum and P. tripalmatum. The seven species are compared with regard to the flower and leaf morphology, palynology and chromosome numbers. They all occur in the winter rainfall region along the west coast of South Africa. The two new species described here are illustrated and a key for the identification of the seven species with a P. aridicola flower type is included.

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.

A New Species

Gladiolus rhodanthus is a new species known from a single population on the summit of the Stettynsberg near Villiersdorp in Western Cape. South Africa The species most closely resembles G. hirsutus and G caryophyllaceus but differs from both in flower shape and markings and in its ecology and reproductive biology. It forms part of a guild of long- tubed, pink-flowered species including  Erica praecox, Pelargonium radiatum and  Watsonia paucifolia which are pollinated by an undescribed long-proboscid fly. Moegistorhynchus sp nov. (Diptera : Nemestrinidae). Gladiolus sekukuniensis is a new species known from three populations south of the Strydpoortberge in Northern Province It closely resembles G. permeahilis subsp  edulis in vegetative features and in flower form, but differs from it in flower colour and in the elongate peri­anth tube. These floral features are apparently adaptations to pollination by long-proboscid flies.

Newly described are two new species of Spiloxene Salisb.:  S. nana Snijman from the Bokkeveld Escarpment, Northern Cape Province, is a shade-loving plant with narrow, pale green leaves and small, white or rarely cream-coloured flowers; S. pusilla Snijman from the Matsikamma, Gifberg and Pakhuis Mountains. Western Cape Province, resembles S. nana in habit but the yellow- or white-tepalled flowers which are tetramerous or hexamerous have darkly coloured stamens and style and an ovary with a short, solid, narrow prolongation at the apex. Inhabiting rock overhangs formed by quartzitic sandstone sheets, both species are close allies of S. scullyi (Baker) Garside from Namaqualand.

The taxonomy of Acanthopsis is poorly understood, resulting in great difficulties in distinguishing and identifying infrageneric taxa. In this contribution a taxonomic account of the shrublet members of Acanthopsis is provided. Four species are recognized, two of which are newly described, namely A. dregeana and A. erosa (both confined to the Northern Cape Province, South Africa). Acanthopsis trispina, hitherto only known from the orginal collection, is considered a synonym of A. horrida. Acanthopsis spathularis has been recollected after more than 180 years and its status as a distinct species is confirmed. The names A. spathularis and A. horrida are lectotypified here. An identification key to the species of the shrublet group in Acanthopsis is provided.

Trachyandra eriocarpa and T. bulbosa are two new species from Northern and Eastern Cape Provinces of South Africa. They are placed in T. sect. Liriothamnus based on their wiry roots, the cataphylls not forming membranous collars, and the remains of the outer leaves forming a fibrous collar. Trachyandra eriocarpa from the Great Winterberg in Eastern Cape is recognised by its unusual, villous ovary and capsules; and T. bulbosa from north of Springbok in Northern Cape by the irregular, bulbous rhizome, microscopically puberulous leaves and maculate tepals.

A New Species

Romulea pilosa J.C.Manning Goldblatt and R. quartzicola J.C.Manning Goldblatt are two narrow endemics from the southern African winter rainfall region. An early, fragmentary collection of R. pilosa from Riviersonderend lacked the diagnostic corm and was thus mistakenly associated with R. tetragona (sect. Ciliatae) as var. flavandra M.P.de Vos because of the highly distinctive pilose, H-shaped leaf. The rediscovery of the taxon in the wild shows it to be a previously unrecognized member of sect. Aggregatae, distinguished by its unusual foliage and bright orange flowers. R. quartzicola was grown to flowering from seeds collected from quartz patches in southern Namaqualand and proved to be a new species of sect. Ciliatae, distinguished by its early flowering, short, subclavate leaves with reduced sclerenchyma strands, and bright yellow flowers with short bracts. R. neglecta M.P.de Vos, a rare endemic from the Kamiesberg in Northern Cape, is a later homonym for the Mediterranean R. neglecta Jord. Fourr., and the earliest name for this plant is shown to be R. speciosa (Ker Gawl.) Baker, typified by an illustration in Andrews’ The botanist’s repository. An epitype is designated to fix the application of the name. We have also examined the type illustration of R. pudica (Sol. ex Ker Gawl.) Baker, hitherto treated as an uncertain species, and are confident that it represents the species currently known as R. amoena Schltr. ex Bég., and takes priority over it as being the earlier name. The type of R. reflexa Eckl., a new name for the later homonym I. reflexa Thunb. and the basionym of R. rosea var. reflexa (Eckl.) Bég., has been mistakenly identified as an Ecklon collection but is in fact the collection that formed the basis of Thunberg’s I. reflexa. This collection is actually a form of R. flava Lam., and the name R. rosea var. reflexa is thus moved to the synonomy of that species. The variety currently known under this name should now be known as R. rosea var. muirii (N.E.Br.) Goldblatt J.C.Manning. Finally, the protologue of R. parviflora Eckl., until now treated under the synonomy of R. obscura Klatt var. obscura, is in fact consistent with R. rosea var. australis (Ewart) M.P.de Vos, and we therefore include the name in the synonomy of the latter.

Capezoum Adlbauer, 2003 is known only from male specimens. Herein, we describe two new species: Capezoum richardi sp. nov. and C. brunneopunctatus sp. nov., from the Northern Cape region in South-Africa. The discovery of these new species, one of them represented by both sexes, allowed us to describe the hitherto unknown female. Moreover, the genus is transferred to the tribe Xystrocerini and a key to the species of the genus is provided. Lastly, the position of Mythozoum Thomson, 1878 in Cerambycidae is discussed.

Two new annual species of Nemesia Vent, are described from southern Africa. Nemesia suaveolens is characterized by magenta and yellow flowers. It differs from the closely related N. euryceras by having a lower lip that is yellow rather than white with pale violet margins, an upper lip with a conspicuous yellow rectangular patch just above the corolla opening, a spur that is ± equal to the length of the lower lip, not half the length, and a hypochile that is yellow rather than dark violet.This new species is known only from the arid Tanqua Karoo east of the Cedarberg Mountains. N. aurantia is characterized by orange saccate flowers with a brown and orange bearded palate. It is closest to N. versicolor, but differs from that species by its orange corolla, the absence of a spur, and its bearded palate with brown and orange trichomes. It is known from a single locality adjacent to the Swart Doting River in Namaqualand between Nuwerus and Garies.

Two New Species

We recognize two new species of Asteraceae from the winter rainfall belt of South Africa and reduce a third to synonomy.  Senecio speciosissimus sp. nov. has been confused with  S. coleophyllus Turcz. in the past but is distinguished by its taller stature, larger and more finely serrated leaves, and congested synflorescences containing (6-)l 5-40 flowerheads. The two species are also geographically separated:  S. speciosissimus occurs in the Hottentots Holland and Franschhoek Mountains of the southwestern Cape, whereas S.  coleophyllus is endemic to the Riviersonderend Mountains.  Chrysocoma hantamensis sp. nov. is a distinctive new species endemic to the Bokkeveld and Roggeveld Plateaus. It is distinguished by its resprouting habit. 3-5-fid leaves and large capitula, 12-15 mm in diameter, with lanceolate. 3-veined involucral bracts, the largest 9 - 1 0 x 2 mm. Investigation of the variation in leaf morphology of the two radiate species of Oncosiphon, O. africanum (PJ.Bergius) Kallersjo and  O. glabratum (Thunb.) Kallersjo. reveals that only one species can be maintained, and O. glabratum is accordingly reduced to synonomy in O. africanum.
