摘 要
描述和报道了发现于中国云南苦苣苔科奇柱苣苔属植物一新种——簇花奇柱苣苔Deinostigma fasciculatumW.H.Chen& Y.M.Shui, sp. nov.。属内新种与多痕奇柱苣苔D.cicatricosum(W.T. Wang) D.J. Middleton & Mich. Möller和弯果奇柱苣苔D. cyrtocarpum(D. Fang & L. Zeng)Mich. Möller & H.J. Atkins相似，都具有深紫色的花和镰状果实，但与他们的区别主要是花序为束状花，花萼萼片（反折，狭披针形，长1.2-1.3厘米），花冠筒（在中部以下明显收缩，外面和喉部以下为白色）。以上三种生长于非石灰岩湿润峭壁附近，具有地理隔离，分布地不同（新种分布在云南东南部，多痕奇柱苣苔分布在广西东部，弯果奇柱苣苔分布在中国广西南部和广东）。

ABSTRACT
A new species of Deinostigma(Gesneriaceae) from Yunnan, China, Deinostigma fasciculatumW.H.Chen& Y.M.Shui, sp. nov., has been discovered and described. In the genus, the new species is similar to D.cicatricosum(W.T. Wang) D.J. Middleton & Mich. Möller and D. cyrtocarpum(D. Fang & L. Zeng)Mich. Möller & H.J. Atkins in dark purple flowers and falcate fruit, but differs from them mainly in theinflorescences with fasciculate flowers, calyx lobes (reflexed, narrowly lanceolate and 1.2–1.3 cm long),corolla tubes (sharply contracted below middle and white outside and below throat). The above three species grow nearby non-limestone wet cliffs and geographically isolated with different distributions (the newspecies in Southeast Yunnan, D. cicatricosumin Eastern Guangxi and D. cyrtocarpumin Southern Guangxiand Guangdong, China).
