Leaves membranous, ovate, slender-petioled, acuminate or acute at the apex, rounded or narrowed at the base, 3-nerved, coarsely dentate, i'-s' long, sparingly pubescent with scattered hairs; petioles often as long as the blades and much longer than the pistillate flower-clusters; sepals of the pistillate flowers lanceolate, nearly equal; achene ovate, acute, i" long. In swampy, shaded situations, often on old logs, New Brunswick to western Ontario and Minnesota, Florida, \JiS- Louisiana, Nebraska and Kansas. Ascends to 3000 ft. in Virginia. Also in Japan. July-Sept. 4. BOEHMERIA Jacq. Stirp. Am. 246. pi. 157. 1763. 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 dioe- cious 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: Boeh
