Basionym: Boehmeria formosana Hayata var. fuzhouensis W.T. Wang (1981b) 403. ― Type: H.H. Chung 2798 (holo F; iso K, UC), China, Fujian, Fuzhou, 28 July 1935 .

Boehmeria platyphylla D.Don var. stricta sensu Chen et al. (2003) 171, non Wright. – See Note 2.

Leaves narrowly elliptic to narrowly ovate, 7–18 by 1.8–4 cm, length 4–4.5 × width, margin with 15–25 shallow teeth, 0.5–2 by 3–6 mm. Fruiting perianth, broadly rhomboid to subspherical, 1–1.5 by 1–1.2 mm, not or scarcely laterally flattened and without marginal rim, base broadly rounded.

Distribution ― South-eastern China.

Habitat & Ecology ― Shaded and disturbed places, e.g., by roadsides, recorded from limestone; 350 m altitude.

Notes ― 1. This variety is distinctive in its leaves very narrowly elliptic-ovate with teeth relatively few broad and short and its fruiting perianth without a marginal rim and with a broadly rounded base. It is restricted to part of the range of the typical variety and apparently rare, only four collections seen. Four additional collections seen from Zhejiang were somewhat intermediate with leaves ovate-attenuate rather than linearelliptic-ovate, and fruiting perianth slightly flattened with slight marginal rim.

2. Var. fuzhouensis was recognised by Chen et al. (2003: 171) under the name B. formosana var. stricta , with the later published epithet fuzhouensis in synonymy. However, although the description in Chen et al. (2003) conforms to var. fuzhouensis all the syntypes of var. stricta (described as B. platyphylla D.Don var. stricta C.H.Wright by Wright (1899: 487)) conform to the typical variety and var. fuzhouensis is therefore the earliest name for this taxon.
