Taxonomic study of Japanese Genus Rosa (Rosaceae)

本研究旨在为日本蔷薇属植物专著的出版提供各种数据。研究结果分组如下：1）发现了特有性状; 2）识别了居群内的变异和地理变异; 3）对Franchet和Savatier描述的种内和种下分类群进行了澄清和选型; 4）补充了Rosa在《日本植物植物群》第2卷b中的手稿（岩月、布福德、大场编），其显著特点如下：1）蔷薇（Rosa luciae Franch.保存（& S）不是'Azumaibara'，而是'Terihanoibara'，2）Rosa wichurae Crep。3）Azumaibara、Moriibara、Yabuibara和Miyakoibara是蔷薇属的种下分类群; 4）接骨木蔷薇Rosa sambucina Koidz是从合花柱组的其它种中分离出来的。列举了日本蔷薇属的所有种名和种下名称。1999年在巴黎召开的蔷薇属分类学国际会议上，就日本蔷薇属分类学的系统问题和新的尝试作了报告。

This study has aimed to provide various data for publishing of a monograph of Japanese Rosa. The results of the study are grouped as follows : 1) finding of the specific characters, 2) recognition of the variations within a population and also geographical variation, 3) the clarification and the lectotypification of the specific and infraspecific taxa described by Franchet and Savatier, and 4) the complementation of the manuscript of Rosa in 'Flora of Japan', vol. 2b (edited by K.Iwatsuki, D.E.Boufford and H.Ohba).The remarkable points are as follows : 1) Rosa luciae Franch. & Sav. are not 'Azumaibara' but 'Terihanoibara', 2) Rosa wichurae Crep. is a synonym of R.luciae, 3) 'Azumaibara', 'Moriibara', 'Yabuibara' and 'Miyakoibara' are infraspecific taxa of R.luciae, 4) Rosa sambucina Koidz is phylogenetically isolated from other species within the sect. Synstylae. All the specific and infraspecific names of Rosa reported from Japan are enumerated. About the systematic problems and a new attempt of the classification of Japanese Rosa were lectured in an international conference of Rosa taxonomy at Paris in 1999.
