 therefrom have grown to be beautiful small trees, of about twenty 

 feet in height, with innumerable branches and branchlets spreading 

 in every directions, with extremities often pendulous, and crowded 

 with beautiful, dark green, glossy foliage. Flowering time in the 

 botanic garden March and April, the fruit ripens in September, Oc- 

 tober, and November.

 firm and glossy, obtusely serrulate, from one to five inches long, 

 and from one to two and a half broad. — Stipules filiform, cadu- 

 cous. — Flowers numerous, small, greenish yellow, collected in little 

 axillary fascicles. — Scales of the corol small, and shorter than the

 fleshy receptacle, two-celied, with one ovulum in each, attached from 

 the base to the bottom of the partition. Style scarcely any. Stigma 

 two- cleft, divisions short and recurved. — Drupes spherical, the size 

 of a cherry, polished, of a lively yellow, one-celled. Pulp soft, gela- 

 tinous and sweet, Nut obovate, considerably flattened, a little ru-
