Abstract

Parnassia farreri is characterised by the petals with long-ciliate petal claw and the broad spatulate staminodes with shallow crenations distally. A sympatric and poorly-known taxon, P. yui, is recorded only from the type collection that morphologically similar to P. farreri. Based on field investigations, examination of herbarium specimens (including the types) and analysis of protologues and distributions, P. yui is hereby reduced to a synonym of P. farreri. Field and anatomy photographs and an updated morphological description of P. farreri are provided. Parnassia farreri is preliminarily designated as Least Concern according to the IUCN Red List guidelines.
