Endemic and rare species of BerberisLinn.and their protection value in Guizhou province

为更好的掌握和保护贵州特有及珍稀植物资源,作者调查了贵州省小檗科小檗属特有植物7种,分别为二色小檗(Berberis bicolor H.Léveillé)、毕节小檗(B.guizhouensis T.S.Ying)、平坝小檗(B.pingbaensisM.T.An)、永思小檗(B.tsienii T.S.Ying)、威宁小檗(B.weiningensis T.S.Ying)、梵净小檗(B.xanthocla-da C.K.Schneider)和紫云小檗(B.ziyunensis Hsiao&Z.Y.Li),以及珍稀濒危植物1种,即二色小檗,该种被《中国物种红色名录》收录,建议优先保护;同时将粉叶小檗(B.pruinosa Franchet)和贵州小檗(B.cav-aleriei H.Léveillé)移出贵州特有植物行列。文章描述了贵州小檗属特有和珍稀植物的保护价值及其分布产地,并整理出贵州省小檗科小檗属植物新名录(共44种1变种),分析其目前存在的问题。

Seven endemic species of Berberis Linn. belonging to the family Berberidaceae, which are Berberis bicolor H. Leveille, B. guizhouensis T. S. Ying, B. pingbaensis M. T. An, B. tsienii T. S. Ying, B. weiningensis T. S. Ying, B. xanthoclada C. K. Schneider and B. ziyunensis Hsiao ＆ Z. Y. Li, were reported in Guizhou province. B. bicolor H. Ieveille, recorded in China Species Red List, is regarded as rare and endangered species and should be pro- tected as a high priority. B. pruinosa Franchet and B. cavaleriei H. Leveille were excluded from the checklist of Guizhou endemic plants. The medicinal value and distribution area of the endemic and rare species of Bereeris Linn. in Guizhou province were also described. A new checklist of Berberis Linn. in Guizhou province, including 44 species and one variety, was given in this paper; moreover, the problems existing in the genus were analyzed and discussed.
