Achenes ovoid to nearly orbicular, 0.9-1.6 × 0.9-1.2 mm, almost glabrous or pubescent with straight and hooked hairs; seeds prominent, conspicuous in outline, surrounded except at base by corky tissue. 2n = 28.

Populations of Boehmeria cylindrica are disjunct in South America.

Plants with thick, often drooping, lanceolate leaf blades, more or less pilose or puberulent abaxially, scabrous adaxially, with short petioles, pilose or puberulent stems, and densely pubescent achenes have been called Boehmeria cylindrica var. drummondiana. These plants are found mostly, but not exclusively, in the southeastern United States and are totally sympatric with more typical plants. The above characteristics may or may not occur together, and each grades into the state found in more typical plants through abundant intermediates. Field and experimental studies are needed to clarify the biologic basis of this variation.
