Rhytidocaulon Piliferum
Rhytidocaulon is a plant genus in the family Apocynaceae, first described in 1962. It is native to northeastern Africa and the Arabian Peninsula ;Species # ''Rhytidocaulon paradoxum'' P.R.O.Bally - Ethiopia # ''Rhytidocaulon piliferum'' Lavranos - Somalia # ''Rhytidocaulon richardianum'' Lavranos - Somalia # ''Rhytidocaulon subscandens'' P.R.O.Bally - Somalia, Ethiopia # ''Rhytidocaulon tortum'' (N.E.Br.) M.G.Gilbert - Arabia ;species with undetermined affinities ;Taxonomy Phylogenetic studies have shown the genus to be monophyletic, and most closely related to the genus ''Echidnopsis'' which inhabits the same region. Marginally more distantly related is a sister branch comprising the genus ''Pseudolithos'' and the widespread ''Caralluma'' stapeliads of North Africa.P. Bruyns, C. Klak, P.

Apocynaceae
Apocynaceae (from ''Apocynum'', Greek for "dog-away") is a family of flowering plants that includes trees, shrubs, herbs, stem succulents, and vines, commonly known as the dogbane family, because some taxa were used as dog poison Members of the family are native to the European, Asian, African, Australian, and American tropics or subtropics, with some temperate members. The former family Asclepiadaceae (now known as Asclepiadoideae) is considered a subfamily of Apocynaceae and contains 348 genera. A list of Apocynaceae genera may be found here. Many species are tall trees found in tropical forests, but some grow in tropical dry (xeric) environments. Also perennial herbs from temperate zones occur. Many of these plants have milky latex, and many species are poisonous if ingested, the family being rich in genera containing alkaloids and cardiac glycosides, those containing the latter often finding use as arrow poisons. Some genera of Apocynaceae, such as '' Adenium'', bleed clea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
