中国景天属一些种的订正

本文对国产景天属的6种植物进行了分类订正。归并了7种1亚种和2变种,同时对中国植物志中景天属存疑种Sedum phyllanthum Levl.et Vant.和S.subtile Miq.的范围及其分类地位进行了讨论。根据对S.hsinganicum Chu ex S.H.Fu的模式标本以及S.floriferum Praeger模式标本图和模式产地标本的研究,确认二者所具性状均在S.aizoon L.的性状变异范围内,故予归并。S.onychopetalumFrod.,S.grammophyllum Frod以及S.anhuiense S.H.Fu et X.W.Wang经研究均被作为S.lineareThunb.的异名处理。S.formosanum N.E.Br.在《中国植物志》中被并入S.alfredii Hance,现恢复为独立的种。此外还报道了一个中国新记录种S.hakonense Makino。

NOTES ON SOME SPECIES OF SEDUM (CRASSULACEAE) IN CHINA

Six species of Sedum are taxonomically discussed and revised in the present paper. As a result, names of seven species, one subspecies and two varieties are reduced. Critical comments on and a full synonym of these taxa are presented. The taxonomic status of 5. phyllanthum Levl. et Vant. and S. subtile Miq. , which were treated as doubtful species in Flora Reipulicae Popularis Sinicae(FRPS) Vol. 34(1), is discussed. S. formosanum N. E. Br. , treated as a synonym of S. alfredii Hance in FRPS, is recognized as a distinct species, and it is found to extend westwards to the mainland of China. S. hakonense Makino is recorded as new to China.
