FLOBULA ADENENSIS. 



Distr. In Asia tropica ! Africa boreali usque ad Cap. Bon. Spei ! 



Hispania ! America tropicali, boreali, et australi ! Australia ! Insulis 



Galapagos ! 



This is an exceedingly variable plant; but even in its most aberrant 



forms the characters of the umbellate inflorescence, exserted stamens and 



style, and the elongated, clavate, ecostate, glandular fruit, can always be 



recognized.

The plant from Aden is so small and strigosely hirsute, with leaves not 

 at all serrated, that it seems almost distinct enough to be ranked as a 

 variety. Judging from his description, Edgeworth seems to have found 

 the normal state of the species.
