| 摘 要： | 报道了樟科油丹属一新种，即黄连山油丹Alseodaphne huanglianshanensis H. W. Li & Y. M. Shui。它产自中国云南东南部绿春县黄连山海拔840-1300 m的热带阔叶次生林中，在体态上与同一分布区内的云南油丹A. yunnanensis Kosterm.十分相似，但叶为长圆形或倒披针状长圆形(5-13×(0.8-)1.2-2.8 cm)，明显较狭，两面几无蜂窝穴，总梗及果梗无毛，密被灰白色小瘤而不同。该新种也与油丹A. hainanensis Merr. 相似，但叶长圆形至倒披针状长圆形，坚纸质，先端锐尖或渐尖，两面几无蜂窝穴，侧脉每侧7-8条，果梗长5-7 mm，密被灰白色条形的小瘤而不同。

| 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.
