中国菊科一新种——香紫菀北大核心CSCD

该文描述了在中国福建北部山区茫荡山发现的菊科(Compositae)紫菀属(Aster L.)一新种——香紫菀(A.artemisiaodorum X.X.Su,S.P.Chen&L.Ma sp.nov.)。基于2个核基因(ITS、ETS)和1个叶绿体基因(trn L-F)片段构建的系统发育树显示,香紫菀具有独立性,与白舌紫菀A.baccharoides(Benth.)Steetz]互为姐妹类群,但该种形态与白舌紫菀相差较大,其全部叶两面无毛、总苞筒状、头状花序1.0~1.8 cm、舌状花5~8朵以及全株具芳香气味等特征。形态特征分析与系统发育分析均支持该新种成立。模式标本现存于福建农林大学标本馆。

Aster artemisiaodorum (Asteraceae), a New Species from China

This paper describes a new species of Aster L. of Compositae, A. artemisiaodorum X.X.Su, S. P. Chen & L. Ma sp.nov., found in Mangdang Mountain, mountainous area of Northern Fujian, China. The phylogenetic tree constructed based on two nuclear genes (ITS, ETS) and one chloroplast gene (trnL F) fragments showed that this species is independent and is a sister group with A. baccharoides, but its morphology is quite different from that of A. baccharoides (Benth.) Steetz. It has the characteristics of hairless on both sides of all leaves, racemose tube, 1-1.8 cm head inflorescence, 5-8 tongue flowers and aromatic smell on the whole plant. The results of morphological characteristics and phylogenetic analysis support the establishment of this new species and should be reported. All the type specimens were preserved in the Herbarium of College of Forestry, Fujian Agriculture and Forestry University.
