is a genus in Pacific Asia that is difficult to classify taxonomically. These difficulties arise from (1) considering the presence of oil bodies as anatomical characters for taxonomic differentiation, (2) the wide occurrence of sibling, semicryptic and geographical vicariant taxa and (3) the inevitable need to organize new datasets for molecular genetic revision of the genus. The present study uses an integrative approach, including molecular genetic, morphological, chorological and ecological methods, to understand the taxonomy of the genus in Amphi-Pacific Asia. As a result, a set of new-to-science taxa was revealed, and the suite of morphological features necessary for reliable discrimination of the taxa was revised. These results are based on the study of a large set of 'fresh' collections suitable for molecular analysis and morphological comparison and include data on oil bodies. The most basal branch in s.l. is segregated into a new genus, Asperifolia. Descriptions of the new taxa and the key to in Vietnam are provided.
是一个分布于亚太地区的属,在分类学上难以归类。这些困难源于:(1)将油体的存在视为分类学区分的解剖学特征;(2)同胞种、半隐种和地理替代类群广泛存在;(3)不可避免地需要整理新的数据集以对该属进行分子遗传学修订。本研究采用综合方法,包括分子遗传学、形态学、分布学和生态学方法,以了解泛太平洋亚洲地区该属的分类学。结果,揭示了一组新的科学类群,并修订了可靠区分这些类群所需的形态特征组合。这些结果基于对大量适合分子分析和形态比较的“新鲜”标本的研究,并包括油体数据。广义的该属中最基部的分支被分离为一个新属,即 Asperifolia。提供了新类群的描述以及越南该属的检索表。
