Boehmeria cylindrica is a deciduous and usually dioecious growing plant. The plant grows to be half a meter to one meter in height with opposite leaf arrangement. Spike-like hairs are in the leaf axils. Leaves are ovate in shape and 6-8 centimeters in length and 3-4 centimeters in width. Flowers are green or greenish white in color and the flowers appear from the axils of the upper leaves. Small, oval shaped seeds are covered in small hook-like hairs. Once mature the seeds are dark brown. The inflorescences resemble spikes and can be from 1-3 centimeters in length. Male and female flowers typically grow on separate plants. Male flowers are more prominently distributed among the spikes in bunches. The female flowers are less continuously distributed along the spikes.
Some of the synonyms and intraspecific taxa are: Boehmeria austrina Small, Boehmeria cylindrica (L.) Sw. var. drummondiana (Weddell) Weddell, and Boehmeria cylindrica (L.) Sw. var. scabra Porter.
