Cyrtandra (plant)

Cyrtandra (New Latin, from Greek κυρτός, kyrtós, "curved", and ἀνήρ, anḗr, "male", in reference to their prominently curved stamens)[1] is a genus of flowering plants containing about 600 species,[2] with more being discovered often,[3] and is thus the largest genus in the family Gesneriaceae.[4] These plants are native to Southeast Asia, Australia, and the Pacific Islands, with the centre of diversity in Southeast Asia and the Malesian region.[4] The genus is common, but many species within it are very rare, localized, endangered endemic plants.[3] The species can be difficult to identify because they are highly polymorphic and because they readily hybridize with each other.[2] The plants may be small herbs, vines, shrubs, epiphytes, or trees. The genus is characterized in part by having two stamens, and most species have white flowers, with a few red-, orange-, yellow- and pink-flowered species known. Almost all species live in rainforest habitats.[3]
