Boehmeria platyphylla D.Don var. cuspidata Wedd.(1856) 365,non B. cuspidata Blume (1857) 216. ― Boehmeria caudigera Wedd. (1854) 199, nom nud. ― Type: Wallich 4585, specimen marked “ U.blanda ” [= Urtica blanda ] (lecto K-WALL;isolecto BR,G; lectotype selected here), Nepal,Nag-arjuhn, 1821. – See Note 1.

Leaf length 1–1.25 × width; marginal teeth 12–20(–25) either side, these all of similar size or progressively wider but not or scarcely longer towards apex, uppermost distal ones at most 2 × length of proximal ones; leaf apex obtuse or broadly rounded in outline excluding terminal tooth, this sometimes only ± twice as long as wide and twice as long as distal marginal teeth, constricted at its base, but usually extremely narrow and tail-like, 10–30 by 1.5–2(–35) mm, length (4–)5–20 × width and (0.1–)0.2(–0.4) × length of rest of lamina. Hairs on fruiting perianth usually ≤ 0.1 mm long.

Notes ― 1. Weddell cites “ U. caudigera & U. blanda, Wallich 4585” which represents two different collections. The one selected here has the number “4585” inserted only in pencil on Wallich’s original label and is not listed in Wallich’s Catalogue, but was selected rather than the one listed in the Catalogue, which is “ U. caudiger a Wall., Mont ad Bumpady, 17 Dec 1821 ”. The latter is less helpful as a type, being of unclear identity somewhat intermediate with B. virgata var. macrostachya .

2. For further taxonomic discussion see under the species as a whole. Over 40 collections clearly referable to this variety have been seen.
