摘要:

于1999年5月至9月,作者先后访问了K、BM、P和S四个植物标本馆,在查阅他们收藏的铁线莲属植物标本的过程中,发现该属的一些分类学问题:(1)发现过去一些学者分别错误地将Clematis montana var.brevifoliola Kuntze,C.apiifolia var.biternata Makino,C.subumbellata Kurz,C.goudotiana Planch.& Triana,C.insidiosa Baill.,C.kockiana Schneid.和C.longicauda A.Rich.等加以归并,这些均应予以恢复。(2)发现过去发表的subsect.Africanae M.Johnson,C.umbellifera Gagnep.,C.pubescens Benth.,C.rhodocarpa Rose,C.edentata Baker,C.djalonensis Cheval.,C.oliveri Kuntze,C.tibetana ssp.vernavi var.dentata Grey-Wilson,C.yunuanensis var.brevipedunculata W.T .Wang,C.clarkeana var.stenophylla Hand.-Mazz,C.subfalcata Pei ex M.Y.Fang,C.angustifoliola W.T .Wang,C.dasyandra var.polyantha Finet & Gagnep.等学名不能成立,应加以归并。(3)对构成黄花铁线莲组sect.Meclatis的二亚组给出新的特征集要;根据C.sericea B.H.K.ex DC.与C.grossa Benth.的形态区别不大,有时甚至难以区分以及二者的分布区一南一北互相邻接的分布格局,认为二者可能为一对姊妹群,并将其等作为一个种的两个地理变种处理;认为在非洲大陆广布并分布到阿拉伯半岛的C.hirsuta Perr.& Guill.包含4变种;将过去置于C.oweniae Harv.的变种var.jonodii移到此种中,并根据C.inciso-dentata A.Rich.特殊的绵毛毛被和内面无毛的萼片等特征,否定过去一些学者将其归并于C.hirsuta的意见,也将其作为C.hirsuta的一个变种处理。(4)描述了单性铁线莲组sect.Aspidanthera的一个特产马达加斯加岛的新亚组subsect.Insid iosae W.T.Wang和尾叶铁线莲亚组subsect.Connatae的一个特产非洲大陆的新系ser.Grandiflorae W.T.
 Wang以及8新种、1新变种。(5)发现杨宗愈等(1991)报道的秀丽铁线莲C.grata Wall.在我国7省区 (西藏东部、云南、四川、贵州、湖北、湖南、江西)有分布所依据的8号标本均非C.grata,而分别是与此 种相近缘的5个种或变种。(6)发现了伏毛绣球藤C.montana var.brevifoliola Kuntze(原知分布于锡金和印度西北部)在我国西藏、尼泊尔、不丹和缅甸北部,缅甸铁线莲C.burmanica Lace(原知分布于缅甸和 泰国)在我国云南西南部,小木通C.armandii Franch.(原知分布于我国长江流域、越南)在缅甸北部和印 度东北部,以及俞氏铁线莲C.yui W.T.Wang(原知分布于我国云南西北部和西藏东南部)在缅甸北部 的新分布。

Abstract:

( 1 ) Some taxonomical problems of the genus Clematis mainly about misidentifications
are discussed, and some treatments including the reinstatement of Clematis montana var. brevifoli-
ola Kuntze, C. apiifolia var. biternata Makino, C. subumbellata Kurz, C. goudotiana Planch.
& Triana, C. insidiosa Baill., C. kockiana Schneid. and C. longicauda A. Rich., and the re-
duction of subsect. Africanae M. Johnson, C. umbellifera Gagnep., C. pubescens Benth., C.
rhodocarpa Rose, C. edentata Baker, C. stoltzi Engler, C. tibetana ssp. vernayi var. dentata
Grey-Wilson, C. clarkeana var. stenophylla Hand.-Mazz., C. subfalcata Pei ex M.Y. Fang,
C. angustifoliola W. T. Wang, C. dasyandra var. polyantha Finet & Gagnep. etc are given.
(2) The new diagnoses for the two subsections of the sect. Meclatis are provided; C. sericea H.B.
K. ex DC. and C. grossa Benth. are treated as two varieties of one species; and a new classifica-
tion of the infraspecific taxa of C. hirsuta Perr & Guill. is made. (3) one subsection, one series,
eight species and one variety are described as new. (4) The new occurrences of C. montana var.
brevifoliola Kuntze in southern Xizang, China, Nepal, Bhutan and northern Myanmar, C. burmani-
ca Lace in southwestern Yunnan, C. armandii Franch. in Assam, India and northern Myanmar,
and C. yui W. T. Wang in northern Myanmar are reported.
