摘要

Ligularia sect. Corymbosae was previously divided into 3 series: Calthifoliae, Retusae and Lapathifoliae. The author places these 3 groups at the rank of subsection based on additional morphological and anatomical studies. Ligularia hodgsonii is placed in sect. Subracemosae I. D. Iliar, because of inflorescence structure. The general inflorescence of L. hodgsonii is a corymb or broad raceme and the heads of the corymb or raceme begin to blossom acropetally, while heads of species of sect. Corymbosaebegin to blossom. basipetally. Ligularia hodgsonii occurs only in Japan and the Kuril Islands and is absent in China. Ligularia dentata is divided into 2 subspecies: L. dentata subsp. dentata and L. dentata subsp. sutchuenensis (Franch.) I. D. Iliar. Plants from south-western and central China, Myanmar and Vietnam are considered as L. dentata subsp. sutchuenensis. This subspecies differs from L, dentata subsp. dentata in its smaller heads (5-8 cm in diam., involucre 0.6-1.5 cm in diam.) and distributionarea.
