Abstract: A new species of Alseodaphne in the Lauraceae, A. huanglianshanensis H. W. Li & Y. M. Shui, is described and illustrated. It was collected from an alt. 840-1300 m tropical broad_leaved secondary forest on the Huanglianshan Mountain, SE Yunnan, China. In habit, the new species is very similar to A. yunnanensis Kosterm. from the same area, but differs by having leaves narrower, oblong or oblanceolate_oblong, 5-13×(0.8-)1.2-2.8 cm, almost not foveolate on both surfaces, peduncles and fruit stalks glabrous and densely greyish white verruculose. The new species is also very similar to A. hainanensis Merr., but differs by having leaves oblong or oblanceolate_oblong, chartaceous, acute or acuminate at apex, hardly foveolate on both surfaces, glabrous, lateral veins 7-8, fruit stalks 5-7 mm long, densely covered with greyish white linear verrucae.
