LXI. PASSIFLORE^. 



This natural order in Angola does not exhibit the brilliancy and 

 beauty of the flowers of the American species, but rather resembles 

 the Cucurbitaceas {Bryonia), and is chiefly represented by the genus 

 Adenia ; one of them, A. lohata Engl., furnishes an edible fruit 

 and also supplies an anthelmintic decoction. Most of the species 

 are erect herbs or tall shrubs. A species of Opliiocaxdon bears 

 fruits as large as a pigeon's G:g^, which are eaten raw or used for 

 making lemonade. Welwitsch was convinced that the genera or 

 subgenera found in the interior of Natal, such as Tryphostemma, 

 etc., are also to be found in the interior of Mossamedes.

Engler in his Bot. Jahrb. xiv. p. 388 (1891), and Harms in Engl. & 

 Prantl, Nat. Pflanzenfam. iii. 6«, pp. 80, 81 (1893), treat Basanantlie 

 as a section of Trypliostemma Harv.; the former genus, however, dates 

 from 18 March 1859, while the latter was not published before the 

 latter part of the same year.
