中国山矾科的初步研究(续)

A Preliminary Study on Symplocos of China (Cont.)

This paper is a preliminary study on the morphology, taxonomy and geog- raphy of Symplocaceae, following the system of H. P. Nooteboom and H. Handel-Maz- zetti et E. Peter-Stibal, who divided the genus into two subgenera according to the floral characteristics.  But I disagree with Nooteboom's unduly broad specific concept, and adopt Handel-Mazzetti et Peter-Stibal's concept, which usually treated the species of this family according to their habitats in regions in a relatively narrow sense.  The ge- nus is divided in the present paper into two subgenera, six sections, among which two are new.  Nine new species and three new varieties are described in this paper.  Discus- sions on some taxa are also presented.      The family Symplocaceae consists of 300 species in the whole world.  They are dis- tributed mainly in tropical and subtropical Asia, Oceania and America.  In China there are about 77 species widely distributed in the  south-western and south-eastern parts, with only one species, namely Symplocos paniculata (Thunb.) Miq. extending northward to north-eastern part.
