Abstract

Abstract: During our expeditions to Dabashan Mountain in June and September 2006 , Primula mallophylla, a species endemic to Dabashan Mountain , Northern Chongqing, China, was rediscovered. Based on observations and collections from Dabashan Mountain , the description of P. mallophylla is revised and emended. A key to P. mallophylla and its related species is provided, and the chromosome numbers and karyotype of this plant are reported. In addition, the current status of P. mallophylla is assessed according to the IUCN Red List Categories and Criteria .

Key words: Primula

摘要： 2006 年6 月份和9 月份, 作者在对重庆市城口县大巴山地区进行考察时, 采集到了中国特有种川东灯台报春( Primula mallophylla) 的标本, 这是近百年来对该种除模式标本外的再度发现。根据在大巴山观察及采集到的材料, 作者对过去该种的特征描述中存在的一些疑问进行了澄清, 更正和补充了其形态描述; 对历史上混淆的几个种列出了检索表; 报道了该种的染色体数目及核型; 根据国际通用的“红色名录等级及标准”对其濒危等级进行了评估。
