Gyrocheilos taishanense: A new species of Gesneriaceae from Guangdong, China
Phytotaxa 478 (2): 216–224
ABSTRACT
Gyrocheilos taishanense G.T. Wang, Yu Q. Chen & R.J. Wang (Gesneriaceae) from south China is described and illustratedwith photographs. It is morphologically similar to G. microtrichum W.T.Wang, but it is distinguished by its glabrous orsparsely hairy pedicels, zygomorphic calyx with hairs in unequal length, and slightly bilobed adaxial corolla lips. Molecularphylogenetic analysis based on nuclear ITS and plastid trnL-F sequences strongly supported this new species as sister to aclade comprising the previously described Gyrocheilos species (100% posterior probability and bootstrap support). The newspecies is evaluated here as Least Concern (LC) according to the IUCN Red List Categories and Criteria.
