Abstract

Primulina malipoensis, a new species from limestone areas around the Sino-Vietnamese border, is described and illustrated. This new species is morphologically similar to P. maguanensis and P. lungzhouensis, but obviously differs from the latter two species by its pale greenish-yellow flowers (vs. purple, with different colour patterns). The phylogenetic affinity, illustration and photographs of this new species are provided in this paper.

Highlights

The recently redefined Primulina Hance has become a species-rich genus within the subfamily Didymocarpoideae of Gesneriaceae (Wang et al 2011, Weber et al 2011, 2013) and its species diversity is still growing due to numerous new species being constantly discovered (e.g. Pan et al 2013, Guo et al 2015, Lai and Wen 2015)
In the P. eburnea complex, geographical isolation has been shown to be a major driver of its diversification and speciation in Primulina (Gao et al 2015, Wang et al 2017)

Summary

Introduction

The recently redefined Primulina Hance has become a species-rich genus within the subfamily Didymocarpoideae of Gesneriaceae (Wang et al 2011, Weber et al 2011, 2013) and its species diversity is still growing due to numerous new species being constantly discovered (e.g. Pan et al 2013, Guo et al 2015, Lai and Wen 2015). During field explorations in 2013, one of the authors (JC) found an unknown species of Primulina near the Sino-Vietnamese border at Malipo County, southeastern Yunnan, China. Flower colour has been used as an important character for the description of new Primulina species (Pan et al 2016, Yang et al 2017).
