600+, see list Cyrtandra (Neo-Latin, from Greek κυρτός, kyrtós, "curved", and ἀνήρ, anḗr, "male", in reference to their prominently curved stamens)[2] is a genus of flowering plants containing about 600 species,[3] with more being discovered often,[4] and is thus the largest genus in the family Gesneriaceae.

[5] These plants are native to Southeast Asia, Australia, and the Pacific Islands, with the centre of diversity in Southeast Asia and the Malesian region.

[5] The genus is common, but many species within it are very rare, localized, and endangered endemic plants.

[4] The species can be difficult to identify because they are highly polymorphic and because they readily hybridize with each other.

[3] The plants may be small herbs, vines, shrubs, epiphytes, or trees.
