- Type
- Type: Arabia, Gorab & Ghunsudam, Forsskahl s.n. (C, holo.)
- Note
- Haines & Lye: “in East Africa only known from a very young specimen from northern Kenya.” They do not cite this specimen. The species is otherwise known from drier northern Africa and from Senegal to Somalia, so it is possible that it does occur in our area; as there seem to be no authenticated specimens, I place it in ‘species of uncertain occurrence’.
