摘要

Acer duplicatoserratum var. duplicatoserratum, var. chinense, A. ceriferum, and A. linganense are distributed in China and Taiwan. Their taxonomic delimitations are obscure because the criteria used to distinguish among these taxa, mainly the degree of pubescence in leaf and petiole, is highly variable within the group. However, further examination of specimens from China led us to resolve the taxonomy in detail. Acer ceriferum and two varieties of A. duplicatoserratum show continuous variation in pubescence, which may reflect alack of divergence between them. Also, some specimens of ^. linganense come from locations near to Zhejiang Province of eastern China, and represent the same characteristics as the plants of A. ceriferum. The only vegetativemorphology is the degree of leaf pubescence, which is highly variable. We could find no other characters that clearly distinguish pubescent taxon from the rest. Therefore, it is not sufficient for taxonomic splitting of these taxa. Acer duplicatoserratum, described by Hayata from Taiwan, is found to be synonymous with taxa from Eastern and Central China known as A. ceriferum and A. linganense. Geographically, A. duplicatoserratum occurs in mountain regions of Jiangsu, Anhui, Zhejiang, Hunan, Shaanxi, and Hubei extending into the west of Hubei and rarely into north and central part of Taiwan. Pubescent individuals mainly grow in peripheral populations, western Hubei and Taiwan.
