very elastic, scentless, and possessing all the qualities of the best 

 samples of that substance.

Leaves lanceolate, flat, acuminate. Flowers very fragrant, in com-

 inserted in the tube ; anthers acuminate, converging, extended 

 at the point into a thread. Styles scarcely any. Follicles re-

A tall elegant tree, with a branching head ; yielding a most copious 

 supply of white coagulable milk. Leaves roundish-ovate, cuspidate, 

 with parallel transverse streaks, very shining, rather stiff, stalked. 

 Peduncles 1-flowered or many-flowered, slender, long, axillary, or in 

 the forks of the twigs. Flowers white. It is probable that this 

 plant, which is very abundant in Cuba, might prove a valuable source 

 of Caoutchouc, as the milk gushes out at the smallest wound, and 

 readily thickens. It is however said, I know not upon what authority, 

 to be so poisonous as to be used by the West Indian natives to en- 

 venom their arrows. Jacquin mentions nothing of it, and in Lunan's 

 compilation the juice is merely said to be acrid.
