摘要: 报道了产自云南屏边的中国蜘蛛抱蛋属一新记录种——垂花蜘蛛抱蛋（Aspidistra nutans Aver.&Tillich）。该种是2017年发表的新种，采集于越南西北部地区，原文缺少果实描述，现补充描述该种果的形态特征。本种与辐花蜘蛛抱蛋（A.subrotata Y.Wan&C.C.Huang）在形态上相近，但其叶片中脉和侧脉明显突出，花梗近先端向下弯曲，长0.8~4.5 cm，花下垂，常贴生于地面，花被紫褐色，常平展，柱头纯白色（后者叶脉凹陷，花梗直立，长约5 mm，花斜向上开，花被暗紫色，内面具有小乳突，柱头白色带紫色斑点）而显著有别于后者。

Abstract: Aspidistra nutans Aver. & Tillich (Asparagaceae), a new species published in 2017, is reported here as a new record species for China. It was first found in northwestern Vietnam and has now been found in Pingbian, Yunnan Province, China. Its fruit characteristics are described here for the first time. This species is similar to A. subrotata Y. Wan & C. C. Huang, but differs by its midveins and secondary veins being prominent on lamina (vs. veins concave); peduncles 0.8-4.5 cm long, hook-like curved distally (vs. ca. 5 mm long, straight); nutant flowers often flowering in underground or semi-underground position (vs. flowering obliquely upward, face up); perigone lobes smooth, purplish-brown (vs. inside papillate, dark purple); and stigma pure white (vs. white with purple spots).
