Popis:	The genus Swertia in South India is revisited based on field and herbarium studies. A brief history of the genus, detailed descriptions, photo plates, nomenclature, distribution and key to the identification of south Indian species are provided. Seven names viz ., Swertia beddomei , S . trichotoma , S. affinis , S. lawii , S. minor, Ophelia elegans and O. umbellata are lectotypified. A new species, Swertia raveendrae , endemic to South India is also described here. The new species is similar to S. lawii but differs by its cordate-orbicular leaves, dense paniculate cymes, small (0.3–1 cm long), ovate-elliptic bracts and the calyx not exceeding the corolla in bud.
