Introduction: The knowledge of polychaetes in the subtropical region of Africa benefited from the activity of J. Day. However, 50 years after the publication of his Monograph of the Polychaeta of southern Africa, it is necessary to reconsider the identity of the Cirratulidae due to changes in the diagnostic characters and new approaches to the taxonomy of the group to corroborate the status of cosmopolitan species in this region. Objective: We hypothesize that biodiversity of multitentacular Cirratulidae polychaetes has been significantly underestimated in southern Africa. Methods: The present work analyzes material deposited in the Iziko museum, as well as recently collected specimens, using scanning electron microscope to identify them. Results: The material corresponds to two new species belonging to the genus Protocirrineris. Protocirrineris strandloperarum sp. nov. is characterized by having the tentacular filaments between the chaetigers 5 to 10-12 and the first pair of branchiae from chaetiger 7, and P. magalhaesi sp. nov. is characterized by having tentacular filaments between chaetigers 4-8 and the first pair of branchiae from chaetigers 2 or 3. Descriptions of these species, with light and scanning electron microscope images, are given. Schematic drawings of the two new species are shown comparatively with diagnostic characters. Conclusions: The use of new techniques enables discovery of new taxonomic characters and two new species of the genus. The diversity of Cirratulidae polychaetes is underestimated also in the subtropical and tropical regions of Africa.

Two new species of Romulea are described from Northern Cape, raising the number of species in southern Africa to 76. R. collina J.C.Manning Goldblatl is endemic to the Hantamsberg near Calvinia. It is distinguished in subgenus Spatalanthus by its clumped habit, yellow flowers with dark markings in the throat, and short papery bracts. A re-examination of rela­tionships within the subgenus suggests that section Cruciatae is not monophyletic and it is accordingly no longer recog­nized as separate from section  Spatalanthus. R. eburnea J.C.Manning Goldblatt is a distinctive species of subgenus Spatalanthus from the Komsberg near Sutherland. It is distinguished by its golden yellow flowers with the apical third of the tepals coloured pale creamy apricot, bracts with broad, translucent margins and tips, and an unusually long perianth tube, 10-13 mm long.

Carex sect. Schoenoxiphium (18 spp.) is a monophyletic group that has its centre of diversity in eastern south Africa. We describe two new species from the Republic of South Africa and Lesotho on the basis of morphological characters. Both new species (C. badilloi and C. parvirufa) are closely related to C. ludwigii, C. kukkoneniana and C. pseudorufa.

Subspecific Level

The species closely related to Euphorbia schinzii in subg. Euphorbia are reviewed for southern Africa. Two new species, E. pisima and E. steelpoortensis are described that are closely related to E. lydenburgensis. Euphorbia complexa is reduced to synonymy under E. schinzii. One new subspecies, E. schinzii subsp. schinzioides, is described for E. schinzii, while E. limpopoana is reduced once again to subspecific level, this time under E. schinzii as E. schinzii subsp. bechuanica. Euphorbia schinzii then has three subspecies. The concept of E. clivicola is extended to include collections from a much wider area than before. A new subspecies, E. clivicola subsp. calcritica, is described for E. clivicola. Euphorbia subsalsa subsp. fluvialis is more closely related to E. otjipembana than to E. subsalsa and consequently is changed to E. otjipembana subsp. fluvialis.

Two New Species

The gekkonid genus Goggia includes eight described species of mostly small-bodied rock dwelling gecko endemic to the southwestern portion of southern Africa, in South Africa and extreme southern Namibia. Previous studies focused on Goggia have employed external morphology and allozyme electrophoresis, but no sequence-based molecular phylogeny of the group has been produced. We have generated a molecular phylogeny of Goggia including all named species and multiple individuals within each species, using sequences of the mitochondrial gene ND2 and nuclear genes RAG1 and PDC. The phylogeny depicts a basal divergence between eastern and western species of small-bodied Goggia, with additional divergences also showing structure strongly correlated with geography. Goggia lineata and G. rupicola are shown to be non-monophyletic, and examination of external morphology supports the distinctiveness of these lineages. We describe two new species to accommodate the southern lineages of “G. lineata” and “G. rupicola”: Goggia incognita sp. nov. and Goggia matzikamaensis sp. nov. Both new species are separated from their northern relatives by geographic barriers: the Knersvlakte plain for G. incognita sp. nov. and G. lineata, and the high Kamiesberg mountains for G. matzikamaensis sp. nov. and G. rupicola. The possible roles of geography, ecology, and climate in promoting diversification within Goggia are discussed.

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.
