中国毛茛科翠雀属的分类学研究（三）：拟澜沧翠雀花、磨顶山翠雀花和粗距蓝翠雀花的名实订正

Taxonomic Studies on the Genus Delphinium (Ranunculaceae) from China (Ⅲ)：The Identities of D. pseudothibeticum, D. motingshanicum and D. caeruleum var. crassicalcaratum

摘要:

通过标本室和野外观察，发现根据云南西北部德钦标本描述的拟澜沧翠雀花（Delphinium pseudothibeticum W. T. Wang& M. J. Warnock）与同样根据德钦标本描述的短角萼翠雀花（D. ceratophorum Franch. var. brevicorniculatum W. T. Wang）属于同一植物，故将前者处理为后者的异名；而根据德钦标本描述的磨顶山“（ 磨顶”应为德钦县羊拉乡茂顶，故“磨顶山”实应为“茂顶山”）翠雀花（D. motingshanicum W. T. Wang & M. J. Warnock）和粗距蓝翠雀花（D. caeruleum Jacq. ex Camb. var. crassicalcaratum W.T. Wang & M. J. Warnock）均与云南西北部颇为常见的宽距翠雀花（D. beesianum W. W. Smith）属于同一植物（磨顶山翠雀花为宽距翠雀花的高大个体），故将磨顶山翠雀花和粗距蓝翠雀花均处理为宽距翠雀花的异名。

Abstract:

Both herbarium and field observations have shown that Delphinium pseudothibeticum W. T. Wang & M. J. Warnock described from Mo-ting (= Mao-ding) Shan, Deqen, northwestern Yunnan, China, is identical with D. ceratophorum Franch. var. brevicorniculatum W. T. Wang, and that both D. motingshanicum W. T. Wang & M. J. Warnock and D. caeruleum Jacq. ex Camb. var. crassicalcaratum W. T. Wang & M. J. Warnock, also described from Mo-ting Shan, are identical with D. beesianum W. W. Smith (D. motingshanicum is no more than a gigantic form of D. beesianum). Delphinum ceratophorum var. brevicorniculatum is currently known only from Deqen, while D. beesianum is a very common species in northwestern Yunnan. Delphinium pseudothibeticum, D. motingshanicum and D. caeruleum var. crassicalcaratum are all synonymized.
