Two new species are described from wild-collected and cultivated material grown at Walter Sisulu National Botanical Garden, Gauteng, South Africa.

Thus far, six species of Delosperma (Aizoaceae subfam. Ruschioideae) have been recorded from the Gauteng province in north-central South Africa, an essentially summer-rainfall region. Of these, two are purple-flowered, one is purple-white-flowered, while the other species are white-or yellow-flowered. We here describe a further purple-white-flowere...

Abstract: The Ledebouria sandersonii and L. cooperii species complexes are studied on the Steenkampsberg, Mpumalanga. Four new species of Ledebouria, two belonging to the L. sandersonii species complex and two belonging to the L. cooperii species complex are described. Their ecology and alliances are discussed.

A new species of Bulbine, B. decastroi (Asphodelaceae subfam. Asphodeloideae), with grass tuft-like leaves, is described from north-central Mpumalanga province, South Africa. Bulbine decastroi is a substrate (peatland) specialist. The species is illustrated and compared to B. capitata.

A new genus Occultia (Scilloideae, Asparagaceaae), is described from Malawi and Mozambique. One of the species on which this genus is based, was originally described as Hyacinthus. The genus is clearly separated from Ledebouria and closely related genera in characters of the flowers and the fruits. In Occultia tepals are united for 1/3 to ½ their l...

Efforts to broaden and improve the genetic stock from which horticultural material of Kalanchoe (Crassulaceae subfam. Kalanchooideae) is made available globally are ongoing. Apart from making small, lightweight , highly floriferous material-both single-and double-flowered-available to the in-and outdoor plant trades, work is also underway to select...

The identity of the little-known Kalanchoe lubangensis R.Fern. (Crassulaceae subfam. Kalanchooideae) is clarified. An amplified description is provided for this endemic species from southwestern Angola, aspects of its ecology are discussed, and it is illustrated. Kalanchoe lubangensis is compared to K. brachyloba Welw., a likely close relative. The...

Abstract The conservation of the unprotected and largely unfenced areas where the Albertina Sisulu Orchid occurs would quickly become degraded due to increased pressure from the rapidly urbanising peri-urban fringe which surrounds the population. While work continues to try and secure some form of formal protection, the duties of caring for the gre...

Brachycorythis conica subsp. transvaalensis Summerh. was first collected in Pretoria in 1918 and described in 1955. Only three subsequent collections had been made in the six decades since its description despite the range centering on the most populous and well-explored part of South Africa. In 2007 a large population of over 100 individuals was r...

The Critically Endangered Albertina Sisulu Orchid remains at only four known locations and numbers less than 150 individuals globally. After its re-discovery in 2007 much research has been initiated to study the biology of the species in a bid to understand and better conserve the species. Chronological history of the species, public awareness, pol...

Discussion around whether WOSA should consider translocation as a means to save orchid colonies from destruction by development activities is presented, guidelines for such translocations are also proposed.

Brachycorythis conica (Summerh.) Summerh. subsp. transvaalensis Summerh. (B.c.t.) was first discovered in 1918 and was named in 1955 by V. Summerhays from a type locality in Pretoria (Summerhays 1955). Since its first discovery the species was recorded only a further 15 times until 2007, when it was rediscovered at a locality in Krugersdorp (McMurt...

Background: Ledebouria Roth (Hyacinthaceae: Hyacinthoideae) is a largely African genus with, more or less, 40 species occurring in South Africa. The species was first collected in December 1990 by R. Archer [Archer, R.H. 503 (PRE)] and remained un-identified. Subsequently, N. Hahn also collected the species in 1992 [N. Hahn 444 (ZPB)] and, upon fai...
