| 摘 要： | 对甘肃锦鸡儿（Caragana kansuensis Pojark.）及其易混种进行了探讨，认为甘肃锦鸡儿与短脚锦鸡儿（C.brachypoda Pojark.）是两个不同的物种。在陕西北部、山西西北部等地被鉴定为甘肃锦鸡儿的类群，实为错误鉴定，其与甘蒙锦鸡儿（C.opulens Kom.）相近，区别在于前者小叶较狭，两面被毛较密，背面干后常发红色，也与白毛锦鸡儿(C.licentiana Hand.-Mazz.)相近，区别在于前者叶柄较长，小叶较长而狭，荚果近光滑。同意赵一之教授的观点，将其作为C.opulens的一个变异类型处理，发表新变种狭叶甘蒙锦鸡儿（C.opulens Kom. var. angustifolia Y. Z. Zhao ex Zhao. Y. Chang et F. C. Shi）。

| Abstract: | A taxonomical note on Caragana kansuensis Pojark.and other confusable taxa is presented in this paper.C.kansuensis Pojark.and C.brachypoda Pojark.should be treated as two distinct species.The plants from North Shaanxi Province,Northwest Shanxi Province and other neighboring areas which misidentified as C.kansuensis Pojark.,in fact,should be a new variety of C.opulens Kom.named C.opulens Kom.var.angustifolia Y.Z.Zhao ex Zhao.Y.Chang et F.C.Shi.The new variety is different from C.opulens Kom.var.opulens by it... |
