| 摘 要： | 自沙芥属(Pugionium Gaertn.)建立以来,本属先后发表了5种及1变种。但就个别种或变种的存在与否及其分布问题,学术界长期以来一直存在争议。作者经查阅标本及在几种植物的主要分布区进行实地调查,通过对本属植物根、叶的形态解剖学结构及种子特性等方面比较研究,认为:本属植物共4种,即沙芥(P. cornutum Gaertn.)、斧形沙芥(P. dolabratum Maxim.)、距沙芥(P. calcaratum Kom.)和翅果沙芥(P. pterocarpum Kom.)。作者同意齿冠沙芥(P. cristatum Kom.)应与斧形沙芥合并,至于宽翅沙芥(P. dolabratum var. platypterum H. L. Yang)实际上就是翅果沙芥(P. pterocarpum Kom.),应予归并。
