<strong>On the specific identity of Chinese endemic species <em>Synotis longipes</em> (Compositae-Senecioneae)</strong>

Abstract

Careful examination of herbarium specimens and observations in the field demonstrate that the morphological features including the stature, the growing style of leaves, the shape of inflorescence as well as the length of peduncles of Synotis longipes are all within the variation range of S. duclouxii, thus S. longipes is morphologically non-distinct from S. duclouxii and should be placed as a synonym of the latter. Color plates, distribution map of S. duclouxii and its related species are provided; the description of S. duclouxii is also revised.
