【摘要】 对二色锦鸡儿(Caragana bicolorKom.)与云南锦鸡儿(C.franchetianaKom.)的鉴别特征进行了研究,认为云南锦鸡儿小叶较大(5～9 mm×3～3.5 mm),针刺较长(4～8 cm),花萼一般呈黄褐色,近纸质,萼齿狭三角形,长3 mm,约为萼筒的1/3,而二色锦鸡儿的小叶较小(3～8 mm×2～4 mm),针刺较短(2～3 cm),花萼一般呈深褐色,近革质,萼齿狭披针形,长约为萼筒的2/3或与萼筒近等长。支持赵一之将吉隆锦鸡儿(C.gyirongensis Ni)归并入云南锦鸡儿,同时将产于西藏林芝及云南德钦一带的粗刺锦鸡儿(C.crassispina Marq.)降为云南锦鸡儿的变种,对其做了新组合。更多还原

【Abstract】 The diagnostic characters of Caragana bicolor Kom.and C.franchetiana Kom.are discussed.The two species can be distinguished by the former having smaller leaflets(3～8 mm×2～4 mm),persistent petiole and rachis on long branch(spinelike) 2～3 cm,calyx leathery,dark brown,teeth narrowly lanceolate,2/3 or nearly as long as tube,while the latter having larger leaflets(5～9 mm×3～3.5 mm),persistent petiole and rachis on long branch 4～8 cm,calyx papery,yellowish brown,teeth narrowly tri-angular,3 mm long,1/3 as long as tube.The reduction of C.gyirongensis Ni to synonymy of C.franchetiana Kom.is supported,and a new combination,C.franchetiana Kom.var.crassispina(Marq.) Zhao Y.Chang et F.C.Shi,is made for those plants with stout spinelike petiole and rachis from local Yunnan and Tibet of China.更多还原
