Tree 30-45 ft. high. Leaves 1-3 dm. 1., broadly or narrowly obovate- 

 elliptical or oblong, usually narrowed at the base, usually with a nerve on 

 each side of the base parallel with the margin ; petiole 3-5 cm. L, glands 

 at apex disk-like. Bracts much longer than the petioles, 6-15 cm. L, 

 linear-spathulate, narrowed petiolar towards the base, the petiolar part 

 longer than the blade, at length dropping off. Anthers 3. Ovary glabrous, 

 ovoid, acuminate. Capsule 3 '5 cm. high, about 7' 5 cm. in diam., endo- 

 carp hard, wooden, thick, exocarp thin. Seeds globular, about 2'5 cm. in 

 diain. Pharmacosycea jamaicensis Liebm. (in Bidensk. Selsk. Skrift. ii. 

 331 (1851) ) is referred by Urban (Symb. Ant. vi. 99) and Pax I.e. to this 

 species. We have not seen the specimen which was collected by Oersted 

 near Kingston. Liebmann's description contains no reference to flower 

 or fruit. 



The timber of this tree is of no service in building, being of a soft 

 brittle nature. The kernels of the nuts in the raw state are delicately 

 sweet and wholesome ; they are produced in great abundance, and, when 

 ripe, they burst from the pod and fall to the ground. When roasted, they 

 are equal, if not superior, to chestnuts. By compression they yield a very 

 sweet and fine-flavoured oil. The cotyledons are emetic and purgative.
