长萼木通属——木通科一新属

ARCHAKEBIA——A NEW GENUS OF LARDIZABALACEAE FROM CHINA

缺瓣牛姆瓜Holboellia apetala Q.Xia,J.Z.Suen et Z.X.Peng在一系列特征上与牛姆瓜属Holboellia植物不同,不应隶属于该属,而代表了一个未被描述过的新属——长萼木通属。新属在茎、叶、果实和花的大部分特征上与木通属Akebia相似,但花萼特征又与野木瓜属Stauntonia接近,其系统位置介于这两个属之间,并偏于前者。

The monotypic genus Archakebia from China is described as new. The genus shares many characters with members of the genus Akebia, except sepals 6, lanceolate or linear, which are common in members of the genus Stauntonia.
