except Toxocarpus and the Periplocee), exceedingly minute, globose 
or oblong, attached in fours to the rather soft pale-coloured pollen- 
carriers ; caudicles none or flap-like. Style usually produced beyond 
the dilated part and often exserted beyond the anthers; apical part 
terete or clavate, obtuse, broadly truncate, bilobulate or bifid. 
Follicles acuminate, smooth. Seeds crowned with a tuft of hairs. 
Climbing shrubs ; leaves opposite, often pellucid-dotted, from the presence of 
crystals of lime in some of their cells; flowers small, usually in 3- to many- 
(rarely 2-) flowered cymes, very rarely solitary ; cymes axillary and terminal. 
Distris, Species many, widely spread through the hotter regions of the Old 
World. 
The pollen masses of this genus are exceedingly minute and their true 
structure is somewhat difficult to determine, and so far as I am aware, there is 
not a single published figure of them that is correct.
