Style terminal : ovules pendulous. 3. Laukocerasus. 



1. CKEYSOBAIiANirS L. Shrubs or trees. Leaf -blades of an orbicular 

 or obovate type. Cymes axillary. Petals clawed. Filaments distinct or 

 nearly so. Stone of the fruit pointed at the base, ridged. — Cocoa-plum. 



Drupe globular or spheroidal : petals cuneate. 1. C. Icaco. 



Drupe obovoid or oblong-obovoid : petals spatulate. 2. C. pellocarpus. 



1. C, Icaco L. Shrub, when growing on beaches, with radially creeping 

 branches, or a tree sometimes 10 m. tall : leaf -blades broadly obovate to orbicu- 

 lar-obovate, mostly 4-8.5 cm. long, typically retuse: sej^als about 2.5 mm.

 oblong-obovoid, sharp-ridged. — Everglades and adjacent hammocks. {Bah., 

 Cuba, Ant.) 



a. GEOBAIjANUS Small. Shrubs, with underground stems. Leaf- 

 blades more elongate than in Chrysobalanus : cymes terminal. Petals not 

 clawed. Filaments markedly united. Stone of the fruit terete, not pointed at
