Strophanthus
''Strophanthus'' is a genus of flowering plants in the family Apocynaceae, first described as a genus in 1802. It is native primarily to tropical Africa, extending to South Africa, with a few species in Asia from southern India to New Guinea and southern China. The genus name is a compound of the Greek words στρόφος (''stróphos'') "twisted cord" and ἄνθος (''ánthos'') "flower", in reference to the Corolla (flower), corolla lobes which, in some species - notably ''S. petersianus'' (see below) - resemble long twisted ribbons or threads and can reach a length of 30–35 cm. This trait, in addition to colouring involving combinations of bright pinks, purples and oranges, combine to make the flowers among the most ornamental in the plant kingdom. The genus includes vines, shrubs, and small trees. The leaf, leaves are opposite or whorled, simple broad lanceolate, 2–20 cm long, with an entire margin. Several African tribes used ''Strophanthus'' as the principa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
