ABSTRACT

Petrocosmea viridis M.Q. Han & Yan Liu, a new tiny and pretty species from Guizhou, China, is described and illustrated. P. virdis was found on damp cliffs in an enormous limestone sinkhole called Dadaihe Tiankeng. It is mostly similar to P. minor in confromation of corolla. The new species differs from the latter with numerous leaves and tiny, light green corolla. In order to compare the two species more accurately, some supplementary and revised description of morphology of P. minor should be added (Cited from Han et al., 2017).
