摘要

Summary During the course of compiling Flora of Wenzhou , several peculiar specimens collected from the region of Wenzhou in Zhejiang Province , cannot be classified into any species previously reported in Zhejiang Province . Based on further specimen investigations and morphological comparisons , those specimens were identified as Ampelopsis aconitifolia Bge . ( Vitaceae) , A . aconitifolia Bge . var . palmiloba ( Carr .) Rehd . (Vitaceae) , Neottia japonica (Bl .) Szlach . (Orchidaceae) , Ziziphus mauritiana Lam . (Rhamnaceae) , which were first recorded in Zhejiang Province . Meanwhile , two genera , Neottia Guett . (Orchidaceae) and Ziziphus Mill.(Rhamnaceae),werealsofirstrecordedinZhejiangProvince.Inaddition,A.aconitifoliaandN.japonica were first reported in East China . The voucher specimens of all the four species were deposited at the herbarium of WenzhouUniversity(WZU) ,andtheduplicatespecimensofA.aconitifolia,A.aconitifoliavar.palmilobaand Z . mauritiana were also preserved at the herbarium of Zhejiang Institute of Subtropical Crops , Zhejiang Academy of Agricultural Sciences . n These newly recorded plants enrich the content of flora in Zhejiang Province and provide fundamental materials for investigation of their geographical distributions in China .%该文报道了分布在浙江省的2个新记录属和4个新记录种植物.2个新记录属分别是鸟巢兰属( Neottia Guett .)(兰科Orchidaceae)和枣属( Ziziphus Mill .)(鼠李科 Rhamnaceae).4个新记录种分别是乌头叶蛇葡萄( Ampelopsis aconitifolia Bge .)，掌裂草葡萄[ A . aconitifolia Bge . var . palmiloba (Carr .)
