Summary: A new Cotyledon species, C. nielsii N.R.Crouch, D.Styles & Mich.Walters, is described from cliffs of the western part of eThekwini Metro near the city of Durban, KwaZulu-Natal province, South Africa. The species is closely allied to the recently described C. petiolaris van Jaarsv. from the Wild Coast region of the Eastern Cape province, but is readily separable on vegetative and reproductive characteristics.
摘要:子叶植物C. nilsii n.r.c roch, D.Styles & Mich。沃尔特斯，是在南非夸祖鲁-纳塔尔省德班市附近的德班地铁西部的悬崖上描绘的。该物种与最近描述的C. petiolaris van Jaarsv密切相关。来自东开普省的野生海岸地区，但在营养和生殖特征上很容易分离。

Summary: The taxonomy and nomenclature of Kalanchoe streptantha Baker (Crassulaceae subfam. Kalanchooideae) are discussed. We show that Baker did not publish the name ‘Kitchingia streptantha Baker', and that the proposed combination ‘Kitchingia streptantha (Baker) L.Allorge’, which is sometimes cited in the synonymy of Kalanchoe streptantha, was not validly published. Although ‘Kalanchoe streptantha Baker non Welwitsch’ is sometimes cited in the literature, no reference could be found to Friedrich Welwitsch having published or at least having proposed the name Kalanchoe streptantha before or after John G. Baker published the name in 1887.

Summary: The name Cotyledon clavifolia Haw., basionym of Adromischus cristatus (Haw.) Lem. var. clavifolius (Haw.) Toelken (Crassulaceae subfam. Kalanchooideae; A. sect. Longipedunculati Poelln.), is lectotypified on a Thomas Duncanson plate held at the Royal Botanic Gardens, Kew. Previous lectotypifications of the name C. clavifolia were not effective. An amplified description is provided for the variety, and it is here recorded from a location northwest of East London.

Summary: A new species of Crassula L., C. sandrae N.H.G. Jacobsen, a succulent from the Western Cape Province of South Africa, is described. It is intermediate in floral morphology and habit between C. tetragona L. and C. biplanata Haw. of the Section Acutifolia (Schönland) Toelken, differing from both, but is most similar in habit and inflorescence to C. biplanata.

Summary: A new species of Cumulopuntia (C. flexibilispina) from north-west Bolivia, which forms hemispherical clumps with dense flexible white spination, is described and illustrated. The species is only known from very high elevations between 4,400m and 4,650m. The new species is compared with and key differences are noted from four other high elevation cumulopuntias: the widespread C. boliviana (including C. boliviana subsp. dactylifera) from Peru, Bolivia and Argentina; C. glomerata (C. boliviana subsp. ignescens) which is found at similar high elevations but in more arid conditions further to the west in Peru, Bolivia and Chile; C. chichensis from southern Bolivia and northern Argentina and finally C. echinacea from southern Peru and northern Chile.

Summary: A morphological and molecular study of Opuntia lasiacantha and Opuntia rzedowskii is presented. These two species have long been considered to belong to the same taxon, although in-depth investigations had not been conducted. Furthermore, no published phylogenetic study of the genus Opuntia includes both species. Our data support the recognition of Opuntia lasiacantha and Opuntia rzedowskii as different species.
