摘要/Abstract

Abstract:

This paper is a preliminary study on the Sabiaceae in aspects of its morphology,

taxonomy and geography. We propose that the Sabioideae and Meliosmoideae as two

new subfamilies of Sabiaceae according to the external morphology, flower structure

and geographical distribution of these two genera respectively.

This paper follows the taxonomic concepts of Luetha Chen on Sabia and C. F.

van Beusekom on Meliosma. We agree with them for their classification of these two

genera above the specific rank. As to the revision work of Sabia by van de Water

and C. F. van Beusekom’s work on Meliosma we disagree for their unduly broad

specific concepts. We rather treat the species of these two genera according to their

habitats in regions on a relatively narrower sense. The genus Sabia of China are

classified into 2 tribes, with 16 species, 5 subspecies and 2 varieties in which 4 sub-

species and l variety are as new combinations, the genus of Meliosma in China are

classified into 2 subgenera with 29 species, and 7 varieties of which 4 varieties are new

combinations.

After examining the affinity of the species of Sabia and Meliosma in China and

its neighboring nations such as Burma, Japan and Bhutan, we found that their migra-

tion initiated from China, as the primitive species of these two genera occured in

northeast and central part of Yunnan, sou theast of Sichuan, north of Guizhou and

west of Hubei, the region may probably be the main origin of these two genera.

As shown in tables 1 & 2, the localities where the species of these two genera den-

sely populate they are from Yunnan, Guangxi, and Guangdong coinciding with the

concepts of C. F. van Beusekom and van de Water about the distribution of exotic

species of these two genera, it may reasonable be pointed out that the center of distri-

bution of these two genera is Yunnan, Guangxi, Guangdong and nieghboring nations,

upper Burma and northern Vietnam. Futhermore, it may be seen that starting from

this center the number of species become less and less as they proceed far and far away

but become more advance in evolution.
