lata Hook．f.& Thoms., C．theobromina Dunn，C．hedysarifolia DC．和C．dissecta Baker的系统位置进行了

讨论，提出了新见解；(2)过去一些作者或不承认C．trifida Hook．，C．pimpinellifolia Hook.,C．oligophyl-

la Hook．，和Clematopsis lineariloba Hutch诸种，或进行降级，作为种下分类群处理。本文作者在研究了有

关标本之后认为上述4种有明显区别特征，均应成立；(3)对裂叶铁线莲Clematis parviloba Gardn．&

Champ．的5个变种，短毛铁线莲C．puberula Hook．f.& Thoms．的4个变种和丝铁线莲组sect．Naraveli-

opsis Hand.-Mazz．的20个种做出新的分类安排；(4)归并了subsect．Potanimianae W．T．Wang，C．heynei

M．Johnson，C．petelotii Gagnep．以及其他几个学名；(5)描述了2新亚组，4新系，3新种和3新变种；(6)

做出了3个新等级，4个新组合。
