China lectotypification new synonymy taxonomy Yunnan Eudicots

Abstract

Thalictrum semiscandens (Ranunculaceae) was described from Lushui County in northwestern Yunnan, China and has been almost totally overlooked since its publication. Based on a critical examination on herbarium specimens (including type material), we demonstrate that it is conspecific with T. trichopus, a species widely distributed in southwestern China (Sichuan and Yunnan). We therefore reduce T. semiscandens to the synonymy of T. trichopus herein. Lectotypification is proposed for T. trichopus.
