安徽老鸦瓣新模式的指定与补充描述

Neotypification and Additional Description of Amana anhuiensis(X.S.Shen) D.Y.Tan & D.Y.Hong(Liliaceae) from Anhui,China

通过对Amana anhuiensis主模式的存放地中国科学院植物研究所标本馆(PE)的查找及向原作者证实,确认该种的模式已不存在。在对模式产地的野外调查过程中,发现仅有这一种老鸦瓣分布,且其花期及果实成熟期植株的一些重要形态性状与原描述不符或在原描述中没有提及,这些性状不仅在个体间比较稳定,而且在种的划分上具有重要价值。它们是:鳞茎皮黄褐色,薄纸质,内侧被绵毛;第1叶自基部向上3/4处最宽;苞片狭披针形;花被片内侧基部具黄绿色斑块;内轮3枚雄蕊比外轮3枚长,花粉黄色,雌蕊花柱与子房近等长。朔果近球形,果喙长10 mm左右。为此,我们指定了该种的新模式,并对其形态特征进行了补充描述。
