A new species of Viola (Violaceae): Viola ramiflora K. O. Yoo

Abstract

A new taxon, Viola ramiflora K. O. Yoo (Violaceae), from Jeju-do is described and illustrated. V. ramiflora shares several characteristics (pale purple flowers; triangular-ovate, ovate, or oblong leaf blades; winged petioles) with the related species V. hirtipes, V. japonica, V. phalacrocarpa, and V. seoulensis. However, this new species has branched cleistogamous and chasmogamous peduncles and oblong-ovate cleistogamous bracteoles.
