摘要
自J.Gaertner于1791年建立沙芥属(Pugionium)以来,一些学者先后在蒙古高原发现了本属的另外几个种和变种。但是,对个别种和变种的存在与否以及本属植物在内蒙古的分布一直存在着分歧意见。作者经实地调查及查阅标本以后认为:本属植物共有4种,即:沙芥(P.cornutum(L.)Gaertn.)、斧形沙芥(P.dolabratumMaxim.)、距沙芥(P.calcaratumKom.)及翅果沙芥(P.pterocarpumKom.);另外,作者同意齿冠沙芥(P.cristatumKom.)应与斧形沙芥合并,宽翅沙芥(P.dolabratumvar.platypterumH.L.Yang)应归于翅果沙芥。以上四种沙芥属植物在内蒙古均有分布。
Since J. Gaertner founded a genus Pugionium in 1791, some scholars have discovered several other species and varieties of the genus in the plateau of Mongolia. However, there have been differences of opinion on whether individual species and varieties exist and distribution of the genus in Inner Mongolia. Through on-the-spot investigations and looking up the specimens, the anthors present a revised classification of Pugionium, in which 4 species are recognized, including P. cornutum(L.) Gaertn., P. dolabratum Maxim., P. calcaratum Kom. and P. pterocarpum Kom.; in addition, the authors agree to incorporate P. cristatum Kom. into P. dolabratum Maxim. and P. dolobratum var. platypterum H. L. Yang into P. pterocarpum Kom.. All above-mentioned four species of the genus Pugionium are distributed in Inner Mongolia.
