番荔枝科糠秕鳞杜氏木群及其近缘种的修订(Ⅱ)——种的描述、地理分布及其相互亲缘关系

REVISION OF DUGUETIA FURFURACEA GROUP AND ITS ALLIES OF ANNONAEAE (I)----- The descriptioris, geographical distributions and relative affinities of the group

杜氏木属(Duguetia St.Hilaire)约80种,全产新热带.它的系统修订系由联合国教科文组织资助的《新热带植物志》(Flora Neotropica)中番荔枝科研究的子课题,本文第一作者有幸参加了该项研究.这里报告的是第一作者于1990年2月至1991年3月在荷兰乌德勒支大学系统植物学研究所进修期间,在 P.J.M.Maas教授指导下完成的番荔枝科杜氏木属中糠秕鳞杜氏木群(Duguetia furfuracea group,为非正式分类学等级)及其近缘种(共16种,现修订至12种)系统修订专著连载的第二部分.它给出了隶属糠秕鳞杜氏木群的叉鳞杜氏木(D.dicholepidota)、莫里杜氏木(D.moricandiana)、马格杜氏木(D.marcgraviana)及具刺杜氏木(D.echinophora)四种的详尽描述、地方名、应用价值、地理分布、分类界定和它们间的相互亲缘关系.短梗杜氏木(D.brevipedunculata)被归并为马格杜氏木的新异名;叉鳞杜氏木与莫里杜氏木不象R.E.Fries(1934,1959)认为那样与马格杜氏木直接亲缘而是与糠秕鳞杜氏木亲缘关系非常密切.

In this part, the detailed escriptions, local names and uses, the geographical distributions, the taxonomic delimitations and the relative affinities of following species, namely, Duguetia dicholepidota, D, moricandiana, D, marcgraviana and D. echinophora which belong to D, furfuracea group in the Sect. Duguetia of the genus Duguetia of Annonaceae are given. D, brevipedunculata is brought into synonymy of D. marcgraviana, D, dicholepidota and D. moricandiana are closely allied to D, furfuracea rather than to D, marcgraviana as being proposed by R. E. Fries (1934, 1959).
