A new species of Orchidaceae, Phalaenopsis zhanhouana , from Xichou County, Yunnan, China, is described and illustrated. The novelty close to P. taenialis wilsonii stobartiana but differs them by having a distinct, fleshy anterior callus with deeply lobed apex at the base labellum lateral lobes reflexed facing outward.

Orchidaceae stands as one of the "flagship" groups in global biodiversity conservation, attracting significant attention from researchers China. Previous studies have focused on taxonomic diversity, neglecting integration phylogeny and functional aspects. Here, we leveraged a large dataset distributions, evolutionary relationships, traits orchids China to analyze geographic patterns species richness (SR), weighted endemism (WE), phylogenetic diversity (PD), (PE), (FD), (FE). Furthermore, analyzed deviations between PD (or FD) SR (PDdev, FDdev), well PE FE) WE (PEdev, FEdev), taking into account climatic environmental variables. We also delineated priority protection survey areas orchid plants Our results revealed that SR, WE, PD, PE, FD, FE for generally exhibited similar trends. However, there were notable inconsistencies geographical PDdev, FDdev, PEdev, FEdev, which might be related different responses these four deviation metrics. pinpointed six conservation China, i.e., southeasterrn Xizang, western Yunnan, central Yunan, Karst area at border Guizhou Guangxi, Guangdong Taiwan Island. In addition, identified certain orchids, encompassing southeastern Xizang other crucial locales. These findings will guide future research efforts aimed safeguarding rich
