Abstract

A new species, Lysimachiafenghwaiana G.Hao & H.F.Yan (Primulaceae), from Hunan Province, China, is described and illustrated. This new species belongs to Lysimachiasubgen.Lysimachiasect.Nummularia and is morphologically similar to L.crista-galli and L.carinata, but is distinctive in its leaf shape and arrangement of flowers. It can be further distinguished from L.crista-galli by the absence of calyx lobule spur, and from L.carinata by the black glandular striates in the corolla lobes, rather than punctate.

Keywords: Ericales; central China; flora; morphological features; taxonomy.
