Primulina guarouba, a new endemic cave-dwelling species of Gesneriaceae from northern Guangxi, China

Nordic Journal of Botany 2024: e04295

ABSTRACT:Primulina guarouba, a new species from the limestone area of northern Guangxi, China, is described and illustrated. According to the maximum likelihood (ML) and Bayesian inference (BI) analysis, it nests in a strongly supported clade (BP=99%) that includes P. cordifolia, P. repanda and P. huangii. Of these, P. guarouba is similar to the P. cordifolia in morphology, but it is easily distinguished from the latter by some of the distinct characters in leaf blade, peduncles, bracts, calyx, corolla, pistil.

Keywords: Didymocarpoideae, flora of guangxi, limestone flora, Primulina cordifolia
