浙江天名精——浙江菊科旋覆花族一新种

Carpesium zhejiangense (Asteraceae,Trib. Inuleae),a New Species from Zhejiang

描述了采自浙江西北部菊科旋覆花族一新种——浙江天名精Carpesium zhejiangense.新种与金挖耳C.divaricatum接近,区别在于前者高60~100 cm,下部茎生叶大,长15~20 cm,宽6~10 cm,总苞较小,直径3~6 mm,花冠外面无毛.基于ITS和trnL-trnF两个片段的聚类分析也证明了新种与金挖耳最为接近,但应作为独立的种.

Carpesium zhejiangense Y.L. Xu, H.W. Zhang et Y.F. Lu, a new species of Asteraceae from north-western Zhejiang, is described with illustrations. This new species is morphologically similar to C. divaricatum, but differs in having 60-100 cm tall stems, larger lower cauline leaves(15-20 cm long, 6-10 cm wide), smaller involucres(3-6 mm in diam.), and glabrous corollas. The phylogenetic analysis based on ITS and trnL-F also demonstrates that it is a distinct spceies and closely related to C. divaricatum.
