摘要:
描述了自甘肃南部发现的葡萄属一新种,文县蘡薁Vitis wenxianensis W.T.Wang。此新种与特产浙江的三出蘡薁V.bryoniifolia Bunge var. ternata(W.T.Wang)C.L.Li有很近的亲缘关系,二者可能是由蘡薁V.bryoniifolia Bunge 衍生而出的一对姊妹群。基于上述认识,将三出蘡薁由变种提升至种的等级,但由于存在一个于1871年发表的种名V.ternata Baker,因此,必须为三出蘡薁拟定一新名。
Abstract:
A new species of the genus Vitis L.,V.wenxianensis W.T.Wang,is described from southern Gansu Province,west China. In having 3sect leaves,it is closely related to V.bryoniifolia Bunge var.ternata(W.T.Wang)C.L.Li,an endemic of Zhejinag Province,East China,differing in its smaller leaves with all segments not divided,minutely denticulate at margin,and densely whitishvelutinous abaxially. In the latter,the leaves are larger,up to 6 cm long and 6.2 cm broad,and the segments are all conspicuously dentate at margin,brownpubescent abaxially,and the lateral segments unequally 2lobed. According to the author’s speculation that these two related taxa might be a pair of sister groups derived from the same species,V.bryoniifolia,in this paper,the latter variety is elevated to specific rank,and for this species a new name must be given owing to the presence of a species name,V.ternata Baker,which was published in 1871 from Brazil.
