摘　　要：描述了采自浙江仙居菊科Asteraceae紫菀族Astereae的一新种——仙居紫菀Aster xianjuensis Y.F.Lu,W.Y.Xie&X.F.Jin.该种形态上接近于匙叶紫菀A.spathulifolius Maxim.和琴叶紫菀A.panduratus Nees ex Walp.,不同前者之处在于叶片背面近无毛,茎中下叶片基部楔形下延成柄,总苞片外面被腺毛,与后者的不同在于茎中下部叶片基部楔形且下延成长柄,总苞片2层,外面密被腺毛与疏柔毛.此外,还附有浙江紫菀属分种(变种)检索表.Aster xianjuensis, a new species of Astereae within the family Asteraceae from Xianju County, is described with illustrations. This new species is similar to A. spathulifolius and A. panduratus, but differs from the former in having leaves nearly glabrous abaxially, caulin leaves base cuneate and attenuate into a long petiole, involucres densely glandulose on outer surfaces. It differs from the latter in having caulin leaves base cuneate and attenuate into a long petiole, involucres 2-seris, outer surfaces densely glandulose and sparsely pilose. Observations of the indumentum of leaf abaxial surfaces, stems and involucres under SEM （Scanning Electron Microscope） showed conspicuously different among the new species, A. spathulifolius and A. panduratus as well. A key to all taxa of Aster from Zhejiang is provided for identification.
