Aspidistra crassifila Yan Liu & C.-I Peng, a new species of the Asparagaceae from Guangxi Zhuang Autonomous Region, China, is described and illustrated.
The new species is similar to A. subrotata Y. Wan & C. C. Huang in the perianth lobes triangular-lanceolate and horizontally spreading, but differs by the perianth campanulate, lobes with appendages at base, stamens 6-8 mm long, filaments enlarged, anthers adnate to perianth tube, connectives extended and upcurved. The chromosome number of the new species was determined to be 2n = 38, and the karyotype was formulated as 2n = 22m+4sm+12st.
A careful study of the literature, herbarium specimens and living plants, both in the wild and in cultivation in the experimental greenhouse, support the recognition of the new species Aspidistra crassifila, which is described herein. Aspidistra crassifila is currently known only from Shiwandashan Mountains, which lie in southern Guangxi. A line drawing, color plates and a distribution map are given for the new species to aid in identification.
描述并图示了中国广西壮族自治区天门冬科蜘蛛抱蛋属的一个新物种——粗丝蜘蛛抱蛋（Aspidistra crassifila Yan Liu & C.-I Peng）。
该新物种在花被片三角状披针形且水平展开方面与万氏蜘蛛抱蛋（A. subrotata Y. Wan & C. C. Huang）相似，但不同之处在于花被钟状，花被片基部具附属物，雄蕊长6 - 8毫米，花丝膨大，花药贴生于花被管，药隔延伸且上弯。确定该新物种的染色体数目为2n = 38，核型公式为2n = 22m + 4sm + 12st。
通过对文献、标本馆标本以及实验温室中野生和栽培的活体植物进行仔细研究，支持对新物种粗丝蜘蛛抱蛋的认定，本文对其进行了描述。粗丝蜘蛛抱蛋目前仅知分布于广西南部的十万大山。给出了该新物种的线条图、彩色图版和分布图，以助于鉴定。
