Order XLVI. ASCLEPIADE.E. 



A very large order of the warm regions of the world, some genera reaching 

 temperate zones. In Socotra there are twelve genera, only two of which have 

 a general distribution in both the old and new worlds ; all the rest are old world 

 species. Four of these range through Africa and tropical Africa, two of them 

 reaching Australia ; one, Ectadiopsis, is restricted to tropical and south Africa, 

 and one, Glossonema, has this African distribution with an extension into Arabia ; 

 one, Boucerosia, is characteristic of the dry plains in the northern hemisphere 

 from Spain to India, one, Echidnopsis, is an Abyssinian genus, and two are 

 endemic. 



1. ECTADIOPSIS. 

 Ectadiopsis, Bentb. in Bentb. et Hook. Gen. PI. ii. 741. 



A small genus of some five or six species, inhabiting east tropical and south 

 Africa. Three of the species are Socotran, two being endemic, and probably 

 the third also.
