Petrocosmea purpureomaculata sp. nov. and P. wui sp. nov. (Gesneriaceae) from Yunnan, China with additions to P. coerulea and P. parryorum

Abstract

Province, China, are described and illustrated. Petrocosmea wui was previously misidentified as P. coerulea due to its shield-shaped leaf base, but can be distinguished by several salient characters. Petrocosmea purpureomaculata is most similar to but distinguishable from P. parryorum. Additions and revisions of previously published descriptions of P. coerulea and P. parryorum, are also provided.

“…Most species of this genus grow on damp limestone walls, and can be found in the limestone areas on and around the Yunnan‐Guizhou Plateau. A number of new taxa have been described in recent years, and there were nearly 70 species in this genus by December 2022, most of which were discovered from hidden niches and caves in previously underexplored island‐like limestone areas (Qiu et al 2015, Yang et al 2019, Cai et al 2022, Han et al 2022, Tang et al 2022, Xu et al 2022). This is the result of nearly 20‐year exploration of plant diversity in limestone areas in China (Duan et al 2021).…”
