摘　　要：通过标本采集与鉴定、馆藏及电子标本查阅、文献检索等,对四川凉山州杜鹃花属(Rhododendron)资源及其分布进行调查,发现杜鹃花科(Ericaceae)一新记录种,即桃叶杜鹃(Rhododendron annae Franch.)。该种隶属于露珠杜鹃亚组(Subsect.Irrorata),与同属于该组的露珠杜鹃(R.irroratum)、蝶花杜鹃(R.aberconwayi)、滇西桃叶杜鹃(R.annae subsp.laxiflorum)较为相似。据文献记录,桃叶杜鹃原来仅分布贵州西部和云南东北部,此次发现扩展了其地理分布范围,扩大了开发利用基础。Based on specimen collecting and identification,consulting collections and electronic specimens,searching documents,etc.the resources and distribution of Rhododendron in Liangshan Prefecture,Sichuan Province were investigated,and a new recorded species of Ericaceae,Rhododendron annae Franch.were found.The species belong to the subgroup of Rhododendron irroratum(Subsect.Irrorata),whichwas similar to the other three species of the same subgroup,R.irroratum,R.aberconwayi and R.annae subsp.laxiflorum.According to the literature records,Rhododendron annae was originally distributed only in western Guizhou and northeastern Yunnan..This new finding expanded its geographical distribution range and expanded the basis of development and utilization.
