Link to Flora of China description P. bracteata is a crevice species found on limestone rock in E Tibet, SW Sichuan and NW Yunnan. It was once separated into three species, but now P. henrici and P. dubernardiana are considered ssp or variations. Color can vary from pink, yellow or white fading to pink. Similar to the related species P. rockii, it can be distinguished by the leaf shape (attenuate base).
