Abstract

Laportea, comprising ca. 22 species, is a genus of the Urticaceae. Two species were previously recorded in the 2nd edition of Flora of Taiwan. In the course of our botanical inventory, one additional weedy species, namely Laportea aestuans (L.) Chew, was found in the central Taiwan. Morphologically, L. aestuans is closely related to L. interrupta (L.) Chew by sharing ovate leaves. Branched racemes of L. aestuans are distinct from the unbranched racemes of L. interrupta. Laportea aestuans is a species mainly distributed at low elevations in central Taiwan.
