濒危植物都支杜鹃雄蕊数目描述的修正

通过对都支杜鹃5个种群（包括模式产地）的雄蕊数目进行统计、对馆藏标本进行查询和对模式标本采集人进行采访，修正了现有文献对都支杜鹃雄蕊数目（一个关键鉴别特征）的描述——应是12~15枚，而非10枚；本文还对同地点栽培的都支杜鹃和云锦杜鹃的形态进行观察，发现都支杜鹃与云锦杜鹃诸多形态特征差异显著，支持都支杜鹃是一个独立的“好种”。

A Revise of Stamen Number to an Endangered Plant:Rhododendron shanii Fang

We corrected the stamen number(a key identification feature) of Rhododendron shanii from 10 to 12-15 through surveying the stamen number of R.shanii from five populations(containing typical locality), investigating plenty of specimens and interviewing the man who collected the type specimens. We also compared the morphology of R.shanii with R.fortunei which were planted in the same location, the result showed that there were many differences between the morphology of these two species, proving that R.shanii is an independent ‘good species’.
