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(英文)

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.WangM.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.WangM.J.Warnock)和粗距蓝翠雀花(D.caeruleum Jacq.ex Camb.var.crassicalcaratum W.T.WangM.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。
