Bruyns Bolus Herbarium Department of Biological Sciences University of Cape Town Rondebosch 7701 Pretoria 2014 S T R E L I T Z I A This series has replaced Memoirs of the Botanical Survey of South Africa and Annals of the Kirstenbosch Botanic Gardens, which the South African National Biodiversity Institute (SANBI) inherited from its predecessor organisa- tions. The plant genus Strelitzia occurs naturally in the eastern parts of southern Africa. It comprises three arbores- cent species, known as wild bananas, and two acaulescent species, known as crane flowers or bird-of-paradise flowers. The logo of SANBI is partly based on the striking inflorescence of Strelitzia reginae, a native of the Eastern Cape and KwaZulu-Natal that has become a garden favourite worldwide. It symbolises the commitment of SANBI to champion the exploration, conservation, sustainable use, appreciation and enjoyment of South Africa’s excep- tionally rich biodiversity for all people.

Based on LM and SEM observations of 56 Apocynoideae species — representing all currently recognized tribes — and eight Periplocoideae, we found strik- ing differences in vessel grouping patterns (radial multiples vs. large clusters) between the mainly nonclimbing apocynoid tribes (Wrightieae, Malouetieae, Nerieae) and the climbing lineages (remaining Apocynoideae and Periplocoideae). The presence of large vessel clusters in combination with fi bers in the ground tissue characterizing the climbing Apocynoideae and Periplocoideae clearly contrasts with the climbing anatomy of the rauvolfi oids (solitary vessels plus tracheids in ground tissue), supporting the view that (1) the climbing habit has evolved more than once in Apocynaceae, (2) the three nonclimbing apocynoid tribes are basal compared to the climbing apocynoids, and (3) Periplocoideae belong to the crown clade.

Manos ABSTRACT. The delimitation of the genus Hoya, with at least 200 species distributed from India and China to Australia, from its closest relatives in the Marsdenieae has long been problematic, precluding an understanding of the evolution and biogeography of the genus. Traditional circumscriptions of genera in the Hoya alliance have relied on features of the flower, but these overlap extensively between clades and may be evolutionarily labile. We obtained chloroplast DNA sequences to infer the phylogenetic relationships among a sample of 35 taxa of Hoya and 11 other genera in the tribe Marsdenieae, namely Absolmsia, Cionura, Dischidia, Dregea, Gongronema, Gunnessia, Madangia, Marsdenia, Micholitzia, Rhyssolobium,andTelosma. Trees were rooted with representatives of Asclepiadeae, Ceropegieae, Fockeeae, Periplocoideae, and Secamonoideae. Hoya and Dischidia form a monophyletic group, but the phylogenetic signal in the chloroplast data analyzed here was insufficient to statistically support the mutual monophyly of the two genera. A monophyletic Hoya, however, must include the monotypic Absolmsia, Madangia,andMicholitzia, a result congruent with their flower morphology.

  • On the Dry Side Central Coast Cactus & Succulent Society September 2017
    ON THE DRY SIDE CENTRAL COAST CACTUS & SUCCULENT SOCIETY SEPTEMBER 2017 SEPTEMBER speaker OF THE MONTH TOM GLAVICH Tom Glavich is a member of the San Gabriel Valley Cactus and Succulent Society as well as most of the LA area clubs. He is a member of the Cactus and Succulent Society Board of Directors and author of the CSSA Journal Beginner’s Guide series of articles. He is also one of the co-chairs of the Inter-City Cactus and Succulent Society show and sale that is held every August at the LA Arboretum. Tom Glavich is a long time grower of succulents, particularly Haworthia and Gasteria. Tom’s presentation on Ha- worthias looks at one of the more popular genera of col- lected African Succulents. They are easy to grow, rela- tively inexpensive and small enough to have a repre- sentative collection. They’re also the subjects of obsessive col- lectors who have thousands of plants. We will look at a brief survey of the forms and then concentrate on the variation in a few species. We will look at recent hybridization work, done in the United States and elsewhere, and discuss basic methods of propagation. At our next meeting, Tom will be selling plants, as well as his book, Beginner’s Guide to Gasteria, Haworthia, Agave and Other Suc- culent Monocots. DON’T MISS Our next meeting!

Chlorocyathus monteiroae. Hooker, Icones plantarum 16, t. 1557 and 1591.] for a specimen collected at Maputo, Mozambique. [Brown, N.E., 1907. Raphionacme monteiroae. In: Thiselton-Dyer, W.T. (Ed.), Flora Capensis, vol. 4. Lovell Reeve and Co, London, pp. 533–534.] sunk the monotypic Chlorocyathus into Raphionacme Harv. However, new information shows that Oliver was correct in regarding Chlorocyathus as different from Raphionacme. The name Chlorocyathus is thus reinstated, and the monotypic Kappia Venter, A.P. Dold and R.L.Verh., which resembles Chlorocyathus closely, becomes a synonym of it. Chlorocyathus will therefore include two species, C. monteiroae Oliv. and C. lobulata (Venter and R.L.Verh.) Venter. Nomenclature, descriptions, distribution patterns, ecology, and a key to the two species of Chlorocyathus are provided. Chlorocyathus is, furthermore, compared with selected African genera of Periplocoideae, and a key is provided to the tuberous-rooted African periplocoid genera. © 2008 SAAB.
