Unarmed trees and shrubs, with watery juices and terete branchlets. Leaves alternate, often two- 

 ranked, serrate, penniveined, three-nerved from the base, short-petiolate, persistent ; stipules lateral, 

 free, usually small, caducous. Flowers apetalous, small, monoecious, dioecious, or rarely perfect, 

 in axillary cymes ; calyx five- or rarely four-parted, the lobes induplicate, valvate or slightly imbri- 

 cated in the bud, or in perfect flowers more or less concave and induplicate ; stamens five or rarely 

 four, opposite the calyx-lobes and inserted on their base, occasionally present in the pistillate flower; 

 filaments short, erect ; anthers oblong, attached on the back near the base, introrse, two-celled, 

 the cells opening longitudinally; ovary sessile, rudimentary or wanting in the staminate flower; 

 style central, slightly or entirely divided into two linear fleshy stigmatic branches ; ovule solitary, 

 pendulous from the apex of the cell, anatropous, micropyle superior. Fruit drupaceous, short- 

 oblong to subglobose, crowned by the persistent style ; exocarp more or less fleshy ; endocarp 

 hard ; seed filling the cavity of the nutlet ; testa membranaceous, albumen fleshy, often scanty ; 

 embryo curved or slightly involute ; cotyledons narrow ; radicle incurved, ascending. 



Trema, with about twenty species, is widely distributed in tropical and subtropical regions of 

 the two hemispheres. Two species reach the coast region and the keys of southern Florida. Of 

 these Trema mollis is a small tree, and Trema Lamarckiana, 1 which in Florida has been noticed 

 only on Key Largo, 2 where it grows as a small shrub, is widely distributed over the Bahamas and 

 many of the West Indian islands. 3
