Perennial stingless herbs (some tropical species shrubs or even trees), with opposite or alternate petioled 3-nerved leaves, distinct or connate stipules, and small monoecious or dioecious flowers, glomerate in axillary spikes or heads, the fertile clusters sometimes leafy at the summit. Staminate flowers mostly 4-parted or the calyx of 4 distinct sepals, usually with a rudimentary ovary. Pistillate calyx tubular or urn-shaped, 2-4-toothed or entire, enclosing the sessile or stalked ovary; stigma subulate, papillose or pubescent along one side. Achene enclosed by the withering-persistent pistillate calyx. [In honor of Georg Rudolph Boehmer, 1723-1803, Professor in Wittenberg.]

About 50 species, mostly natives of tropical regions, the following of eastern North America. Type species: Bochmeria rami flora Jacq.
