218 HEPTANDRIA MONOGYNIA. Jouesilt. 



Female. Calyx as in the male. Corol none. Stamens 

 none. Germ superior, conical. Style longer than the 

 calyx. Stigma headed. Pericarp none, the calyx now 

 enlarged, and contracted at the mouths serves for one. 

 It is five-sided, each angle being armed with two or three 

 rows of conical, headed, very glutinous glands. Seeds 

 one, nearly cylindric, &c. as described by Gosrtner. 



It makes most excellent, impenetrable fences, and when 

 fairly caught in its trammels, it is no easy matter to be 

 extricated, the prickles beinjr so numerous, strong, crook- 

 ed, and sharp. Both Konig and myself were so situated a- 

 mongst the Vandalore hills near Madras, and hence he 

 named it T. horrida, not at that time suspecting it to be 

 Pisonia aculeata. 



Plants received from the West Indies into the Botanic 

 garden at Calcutta, do not in any respect difier from our 

 East Indian one, which grows common in forests, hedges, 

 &c.
