'''''Strophanthus''''' is a genus of 35-40 species of [[flowering plant]]s in the family [[Apocynaceae]], native mainly to tropical [[Africa]], extending to [[South Africa]], with a few species in [[Asia]], from southern [[India]] to the [[Philippines]] and southern [[China]]. The name (''strophos anthos'', "twisted cord flower") derives from the long twisted threadlike segments of the [[Corolla (flower)|corolla]], which in one species (''S. preussii'') attain a length of 30–35 cm.

Strophanthus (Greek, twisted cord and flower, alluding to the corolla-segms.). Incl. Roupellia. Apocynaceae. Shrubs, often scandent, glabrous or more or less hairy, with persistent or deciduous foliage, suitable for the warmhouse: lvs. opposite, rarely ternate: infl. terminal, often at the ends of short branches, corymbose, many- or few-fld. or reduced to solitary fls.: fls. mostly showy; sepals 5, imbricate, sometimes foliaceous; corolla funnelform or campanulate, tube cylindrical, long or short, mouth with paired appendages alternating with the lobes which are 5, acuminate and produced into very long filiform tails; disk none: mericarps 2, follicular, oblong or fusiform, divaricate.—About 40 species, Trop. and S. Afr. and Trop. Asia.
