Molecular systematics of Chiritopsis-like Primulina (Gesneriaceae): one new species, one new name, two new combinations, and new synonyms.

ABSTRACT:

Background

The Gesneriaceae genus Chiritopsis, confined almost exclusively to cave or cave-like microhabitats of limestone karsts of southern China, was described to distinguish it from Chirita by much smaller flowers and generally miniature plant sizes in the former genus. However, molecular phylogenetic analyses showed that Chiritopsis is polyphyletic and its species delimitation has been problematic. To understand how many times Chiritopsis-like species have evolved from within the recircumscribed Primulina and to further clarify their species identification, we sampled all but two recently described species of Chiritopsis-like Primulina and reconstructed their phylogenetic relationship based on DNA sequences of nuclear ITS and chloroplast trnL-F and trnH-psbA.
