Abstract

Ligularia shifangensis (Asteraceae, Senecioneae) has been treated as L. liatroides var. shifangensis. Observations of both herbarium specimens (including type material) and living plants demonstrate that L. shifangensis is a distinct species. From L. liatroides it can be readily distinguished by the shape of leaves and involucres, the number and pubescence of phyllaries, and a shorter pappus. The affinity of L. shifangensis may lie with L. tsangchanensis, from which it differs mainly in the shape of involucres, the length of peduncles and a shorter pappus.
