| 摘 要： | 报道了在广西岩溶洞穴发现的苦苣苔科Gesnenaceae小花苣苔属Chiritopsis一新种——灵川小花苣苔C．lingchuanensis Yah Liu＆Y.G.Wei。本种因聚伞花序花稀疏，花冠白色，明显二唇形，上唇比下唇短3倍以上，退化雄蕊3而与羽裂小花苣苔C.bipinnatifida W .T．Wang相近，区别在于前者叶不裂，雄蕊被短柔毛。本种在叶形上还与小花苣苔C.repandaw T.Wang相近，不同在于后者花冠不明显二唇形，上下唇近等长，雄蕊无毛，退化雄蕊2。灵川小花苣苔的分布范围狭窄，目前仅见于一个岩溶洞穴的近洞口段，具明显的洞生习性。

| Abstract: | A new species of Gesneriaceae, Chiritopsis lingchuanensis Yan Liu & Y. G. Wei, which was found to grow in a karst cave in Lingchuan County, Guangxi, China, is described and illustrated. The new species is similar to C. bipinnatifida W. T. Wang in having cymes lax-flowered, the corolla white, distinctly 2-lipped, the posterior lip three times shorter than the anterior one, and the staminodes 3, but differs by having leaves undivided and stamens pubescent. The new species is also similar to C. repanda W. T. Wang in the leaf shape, but differs in its corolla indistinctly 2-lipped, the posterior lip subequal to the anterior one, stamens glabrous, and the staminodes 2. |
