Petrocosmea forrestii, leaf rosette

Petrocosmea is a genus of the family Gesneriaceae, the African violet family. Most of the species within this genus are endemic to high-altitude areas in Western China,[1] although some are native to other parts of Asia.[2] It is a rosette forming genus that generally grows on wet mossy rocks or forests.[1][2]

The genus was discovered in China by Augustine Henry and was first described in 1887 by Daniel Oliver (Prof. of Botany, University College, London).[2]


The genus contains around 25 species. The species listed below are taken from The Plant List as of February 2013,[3] unless otherwise indicated.

A new species Petrocosmea cryptica J.M.H.Shaw was described in 2011, long known in cultivation but mistakenly identified as P. rosettifolia.[5] A further eight names were considered "unresolved"; they may be extra species or synonyms of existing species:[3]
