IV. ATRIPLICEAE. Herbs or shrubs. Leaves opposite or alternate, 
glabrous, or usually pubescent with inflated or stellate hairs. Flowers mostly 
unisexual, monoecious or dioecious, perfect flowers sometimes intermixed 
with the unisexual ones, usually glomerate, the glomerules axillary, spicate, 
or paniculate. “Stamens 1-5. Fruit compressed or obcompressed, included 
in the bracts, these often united and accrescent in age. Seed erect or hori- 
zontal; embryo annular. 
Pubescence of inflated hairs, or wanting; seed vertical or horizontal. 
Bracts of the pistillate flowers usually compressed, never strongly obcompressed. 
Stigmas 4 or 5; leaves and stems glabrous; bracts united to the apex. 10, SPINACTA.
