232; see text Primulina is a genus of flowering plants in the African violet family Gesneriaceae.

It includes 232 species native to southern and north-central China and northern Vietnam.

[1] The species are mostly calciphilous, and typically grow in the extensive limestone karst regions of China and Vietnam.

[3] In 2016 five species were moved to the genus Deinostigma,[4] which was merged into Metapetrocosmea in 2022.

[5] A phylogenetic study published in 2023 concluded that the southernmost three species of Primulina, endemic to the Langbiang Plateau in southern Vietnam, constitute a separate genus which was named Langbiangia.
