Primroses, approximately 1000 species from the family Primulaceae, are mostly distributed in subalpine to alpine areas and attract attention due to their high ornamental value. However, they have been increasingly threatened by human activities and climate change in recent decades. China harbours 535 primrose species from 12 genera, most of which are endemic. In this study, we established a distribution database of the primroses in China, then explored the geographic pattern of the richness of primrose species in relation to environmental factors and evaluated their conservation status.
