生长于中国云南泥灰岩悬崖上以前被误认为秋海棠叶石蝴蝶的新种——金毛石蝴蝶(苦苣苔科石蝴蝶属)

摘要
报道和描述了发现于中国云南的新种,金毛石蝴蝶。金毛石蝴蝶被发现与黑眼石蝴蝶一起生长在磨盘山常绿阔叶林中潮湿的泥灰岩悬崖上。新种几十年前被苦苣苔科植物爱好者培养,并使用秋海棠叶石蝴蝶这个名字几十年,它的斜生钟状花冠筒与秋海棠叶石蝴蝶确实相似,但可以从以下特征进行区分,新种花丝中部覆有金黄色羊毛状柔毛;开花初期,花色为报春花黄色,然后变为白色。
Petrocosmea chrysotricha M.Q.Han, H. Jiang & Yan Liu, a new species from Yunnan, China, is described and illustrated. Petrocosmea chrysotricha was found growing with P. melanophthalma on damp marlstone cliffs in evergreen broad-leaved forest on Mopan Shan. The new species has been grown for decades by Gesneriad enthusiasts under the name P. begoniifolia for decades and it is indeed similar to P. begoniifolia in its oblique campanulate corolla tube, but differs by having flaments covered with golden lanate indumentum in the middle part and by having primrose yellow flowers at the beginning if anthesis, then turning white.
