 Fruit a small oblong or globose drupe or nut, the exocarp often waxy. Seed 

 erect. Endosperm none. Cotyledons plano-convex. Radicle very short. 



Two genera and 35 species of wide geographic distribution.

Shrubs or small trees with entire, dentate or lobed, mostly resinous dotted leaves, our 

 species usually dioecious. Staminate atueuts oblong or narrowly cylindric, expanding be- 

 fore or with the leaves. Stamens 4-8. Pistillate aments ovoid or subglobose; ovary sub- 

 tended by 2-4, mostly short, deciduous or persistent bractlets. Drupe globose or ovoid, its 

 exocarp waxy. [Ancient Greek name of the Tamarisk.] 



Besides the following species, another occurs in the Southern States and 2 on the Pacific coast.
