番荔枝科糠秕鳞杜氏木群及其近缘种的修订(Ⅳ)——形态描述、地理分布及标本索引(英文)

REVISION OF DUGUETIA FURFURACEA GROUP AND ITS ALLIES OF ANNONACEAE (IV)——The morphological descriptions, geographical distributions and list of exsiccata

文章第一作者有幸参加了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.该文报告的是作者对番荔枝科杜氏木属(Duguetia St.Hilaire)中糠秕鳞杜氏木群(D.furfuracea group)及其近缘种(共16种,现修订至12种)的系统修订专著连载的最后一部分,给出了与糠秕鳞杜氏木群亲缘的里德杜氏木(D.riedeliana)、小叶杜氏木(D.microphylla)及柳叶杜氏木(D.salicifolia)的详细形态描述、地方名、应用价值及地理分布.对它们的分类界定和相互亲缘关系也作了讨论:里德杜氏木产巴西东北至东南沿海,与其余二种易于区别,而小叶杜氏本与柳叶杜氏木均同产巴西东南部沿海狭窄的区域里,形态特征亦十分相近,是否为同种还有待进一步研究,此外,文中还提供了一个世界上25余个标本馆所藏的糠秕鳞杜氏木群及其近缘种的标本索引.

The detailed morphological descriptions, local names and uses, geographical distributions of following three species, namely. Duguetia riedeliima. D. mtcrof/tylla and D. salicifolia which belong to the allies of D. furfxracea group in the Sect. Duffttetia of the genus Duguetia of Annonaceae are given. D. rieielima. widely distributed in NE to SE costal areas of Brazil, can be easily distinguished by morphological characters from the other two species, while D. microfhflla and D. salicifolia. restrictly distributed in SE costal area of Brazil, come very much close each other. Wether they are distinct or conspecific remains problematic. Additionally, a list of exsiccata is presented: see appendix A-B.
