Box FAMILY. 
Monoecious or dioecious trees, shrubs or perennial herbs, with alternate or 
opposite simple mostly evergreen leaves, the sap not milky. Flowers clustered 
or solitary, regular, bracted, with or without a perianth (calyx). Petals none. 
Staminate flowers with 4-7 distinct stamens, the anthers 2-celled; sometimes 
with a rudimentary pistil. Pistillate flowers with a 2-4-celled (mostly 3-celled) 
ovary, with 2 or 1 anatropous ovules in each cavity; styles as many as the 
ovary-cavities, simple. Fruit a capsule or drupe, its carpels 1-2-seeded. Em- 
bryo straight; endosperm fleshy, or almost wanting. 
About 6 genera and 30 species, only the following and the Californian Simmondsia in North

same spike. Staminate flowers with 4 sepals; stamens 4, opposite the sepals; filaments 
thick, long-exserted; anthers 2-celled, the sacs longitudinally dehiscent. Pistillate flowers 
with 4 sepals or more; ovary 3-celled, the cavities with a partition at the base; styles 3, 
spreading; ovules 2 in each cavity. Capsule of 3 2-seeded carpels. [Greek, thick stamen. ]
