A New Species

A new species of the southern Africa endemic genus Eliokarmos, that includes the well-known chincherinchees, is described from the vicinity of Kotzesrus, Northern Cape Province of South Africa. Eliokarmos humanii sp. nov. is unique in the genus based on its single, slightly fleshy, suborbicular, convex leaf with ciliate margin, and the short subspiciform inflorescence with almost sessile flowers. A complete description is presented for this species, and data on morphology, ecology, and distribution are reported. In addition, Ornithogalum richtersveldensis, recently described from northwestern South Africa, is transferred to Eliokarmos based on its morphology and biogeography, and a new combination is presented for this species in the latter genus.

A New Species

Among the recently described genera in Hyacinthaceae subfamily Urgineoideae (= Asparagaceae subfam. Scilloideae tribe Urgineeae), Austronea Mart.-Azorín, M.B.Crespo, M.Pinter & Wetschnig in Martínez-Azorín et al. (2018: 105) includes 20 species restricted to southern Africa (Martínez-Azorín et al. 2018, 2019a, 2019b). Some such species were traditionally included in Urginea Steinheil (1834: 321) or Drimia Jacq. ex Willdenow (1799: 165) sensu lato and resemble those of Fusifilum Rafinesque (1837: 27), a phylogenetic relationship supported by molecular data (Martínez-Azorín et al. in prep.). However, species of Austronea are easily identified by a unique syndrome of morphological characters, the most characteristic being the subcorymbose or congested raceme that commonly nods during early developmental stages, the green to yellowish ovary (in contrast to the white gynoecium of Fusifilum) and the tetrahedrally folded seeds with narrowly winged angles (see Martínez-Azorín et al. 2018).

A New Species

Clivia mirabilis Rourke is a new pendulous tubular-flowered species from Oorlogskloof Nature Reserve in Northern Cape. Its distribution area is some 800 km outside the previously accepted range of the genus Clivia. This sun-tolerant species is adapted to an arid Mediterranean climate, producing vegetative growth in winter and maturing its seeds rapidly in late summer/early autumn to synchronize with the arrival of winter rains.

A New Species

The genus Acanthistius Gill, 1862 comprises ten putative valid species occurring in shallow warm-temperate waters of the Southern Hemisphere: South America (coasts of Ecuador, Peru, Chile, Brazil, and Argentina) southern Africa (Namibia and South Africa), southern Australia, New Zealand, Lord Howe, Norfolk, Kermadec and Easter, and Sala y Gómez islands. Two species: Acanthistius sebastoides (Castelnau, 1861) and Acanthistius sp are known from shallow waters of the east coast of South Africa (Heemstra and Randall, 1986). The latter taxon, previously known from a brief description of a single specimen, is here described from 23 specimens and named Acanthistius joanae. Acanthistius sebastoides is redescribed from 13 specimens and compared with A. joanae and species of Acanthistius known from South America and Australia. A neotype is designated for Serranus sebastoides Castelnau, 1861, as the two syntypes are apparently lost.

A New Species

A re-examination of the herbarium material has allowed to describe a new species, Corbichonia exellii, occurring in Southern Africa (Angola, Namibia and South Africa). C. exellii represents the third species in the genus. Morphological differences between all three Corbichonia species (C. decumbens, C. rubriviolacea, and C. exellii) are provided. The description of the genus is defined using the newly discovered characters (reproductive features). The taxonomy of all Corbichonia species (synonyms included) is provided, as well as maps for all species. The lectotypes of Orygia decumbens (basionym of Corbichonia decumbens) and O. mucronata (synonym of C. decumbens) are designated on specimens preserved, respectively, at BM and K. The genus Corbichonia, recently placed in Lophiocarpaceae, is markedly different from the core genus Lophiocarpus on the basis of embryological, morphological and carpological characters, and deserves further investigation concerning its taxonomic status.

Notes are provided on a collection of Afrotropical harvestmen (Opiliones: Palpatores: Phalangiidae) from the California Academy of Sciences. A new species of Rhampsinitus, R. conjunctidens n. sp., is described from Limpopo province of South Africa. Rhampsinitus flavobrunneus Staręga 2009 and R. silvaticus Lawrence 1931 are recognised as junior synonyms of R. nubicolus Lawrence 1963 and R. vittatus Lawrence 1931, respectively. Both R. conjunctidens and R. nubicolus are recognised as exhibiting strong male dimorphism with major males exhibiting larger body size and greatly enlarged chelicerae relative to minor males; minor males cannot be readily identified to species without examination of genitalia. A discussion is also provided on generic boundaries within Afrotropical Phalangiidae, and a generic key to males of the region is presented.

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).

African Genus

Background: Berkheya is a large, mainly southern African genus of approximately 75 species, several of which are poorly known and under-collected. Since revision in 1959, only a few new species have been described. Publication of new taxa facilitates conservation objectives and contributes to a better understanding of the southern African flora.Objectives: The objectives of this study were to describe a new species of Berkheya, consider its taxonomic position within the genus and assess its conservation status.Methods: Macromorphology and micromorphology of the new species were compared with known species.Results: Berkheya dumicola N.G.Bergh Helme was described from two subpopulations from the northern Bokkeveld escarpment, Northern Cape Province, South Africa. The species is a tall shrub with radiate flowerheads, toothed receptacle alveole margins, a uniseriate pappus of small, rounded scales and very short twin-hairs on the cypsela.Conclusion: Berkheya dumicola is a new species with a unique combination of features. Based on morphological characteristics, its closest relative within the genus is likely to be the recently describedBerkheya chrysanthemoides J.C.Manning Goldblatt. The limited geographic extent and small population size of B. dumicola warrant an International Union for Conservation of Nature (IUCN) status of ‘Endangered’.
