Abstract

A new species of Gesneriaceae, Primulina titan, is described and photographed from northern Guangxi, China. It resembles P. hunanensis,but can be distinguished by combined morphological characters of leaf,bract, corolla, stamen and pistil. We found only one population with approx.800 mature individuals at the type locality. This species is provisionally assessed as vulnerable [VU D1] using IUCN criteria.
