【摘要】 通过检查藏南翠雀花Delphiniumnortonii的主模式标本 ,发现《中国植物志》、《西藏植物志》和《Flo raofChina》中对该种的鉴定和描述有误。该种的花的退化雄蕊黑褐色 ,属于翠雀亚属的密花翠雀花组subgen .Delphinastrumsect.Elatopsis,而上述几种植物志中长期以来将其置于退化雄蕊为蓝色或蓝紫色的翠雀组sect.Delphinastrum中。这几种植物志中记载的D .nortonii实际上代表一个新种 ,即李恒翠雀花D .lihengianum。D .nortonii略相似于冰川翠雀花D .glaciale,而李恒翠雀花与蓝翠雀花D .caeruleum近缘。本文对D .nortonii这一相当稀见的种进行了详细描述并提供了主模式照片更多还原

【Abstract】 Examination of the holotype of Delphinium nortonii has shown that the description on this species in the Chinese floristic works, such as the Flora Re ipublicae Popularis Sinicae, Flora Xizangica and Flora of China, was derived from a misidentification, and thus is not correct, and that the plants from Xiza ng previously referred to the species in these works actually represent a very d ifferent species, i.e. D. lihengianum. D. nortonii, which has flowers wi th black_brown staminodes, should be a member of Delphinium subgen. Delphi nastrum sect. Elatopsis, and may be somewhat related to D. glaciale, w hile D. lihengianum, which has flowers with blue staminodes, should be a mem ber of Delphinium subgen. Delphinastrum sect. Delphinastrum, and may be closely related to D. caeruleum. D. nortonii is likely a very rare s pecies, known only from its type locality, Kampa Dzong in Yadong County, S Xizan g, China. A detailed description of this species is given and its holotype is ph otographed.更多还原
