报道了大花棘豆在河北省的新分布 ,并通过对标本、资料的研究 ,对 De Candolle所建立的大花棘豆的三个种下分类单位进行了修改 .认为大花棘豆应包括二个变种 :分布于西伯利亚与我国河北省的原变种大花棘豆 var.grandiflora和分布于内蒙古自治区及东北地区的变种狭翼大花棘豆 var.leptoptera DC.

The author reports the new distribution O.grandiflora (Pall.)DC.from Hebei Province,and suggests that O.grandiflora (Pall.)DC. should be divided into two verieties,the one in Russia and Hebei Province is O.grandiflora (Pall.)DC.var.grandiflora,another one in Neimonggol and East-North China is O.grandiflora (Pall.)DC. var. leptoptera DC.;
