Gomphocarpus R. Br.

Gomphocarpus is an African-Arabian genus with ca. 20-25 species (Goyder & Alexander 2001). It has often been included in a broadly circumscribed genus Asclepias (e.g. Knees 2000). However, molecular studies have demonstrated that Asclepias s.str. only includes species from the New World (Fishbein & al. 2011).
A single variable species, G. fruticosus (L.) R. Br. (syn.: Asclepias fruticosus L.), is sometimes grown as an ornamental (Knees 2000, Jäger & al. 2008) and has been recorded as an escape in Belgium.
