Paraphlomis caloneura (Lamiaceae), A New Species From Guangxi, China

Abstract— Paraphlomis caloneura , a new species from Guangxi Zhuang Autonomous Region, China, is described and illustrated. Molecular phylogenetic analyses based on two nuclear ribosomal DNA regions (ITS and ETS) and three plastid DNA markers ( rpl32-trnL , rps16 , and trnL-trnF ) revealed that the new species is sister to P. hirsutissima . Both species are found in the limestone forests and are geographically close to each other, but P. caloneura can be easily distinguished from P. hirsutissima by its oblong or ovate-oblong and adaxially densely hispid laminas with broadly cuneate to cordate bases, densely hispid petioles, and slightly 2-lobed margins of upper corolla lips.
