Vailia is a monotypic genus of flowering plants belonging to the family Apocynaceae. It just contains one species, Vailia mucronata Rusby[1]
It is native to Bolivia, Ecuador and Peru.[1]
The genus name of Vailia is in honour of Anna Murray Vail (1863–1955), an American botanist and first librarian of the New York Botanical Garden.[2] The Latin specific epithet of mucronata means sharp-edged, from mucro, sword-point or edge.[3] Both the genus and the species were first described and published in Bull. Torrey Bot. Club Vol.25 on page 500 in 1898.[1]
