    Abstract

    A new species of the genus Gentianella, G. devendrae sp. nov., from the cold desert of Ladakh in northwest Himalaya, India is described and illustrated. The species shows morphological resemblance with Gentianella azurea, but differs from the latter in having always dwarf habit (plants never more than 2 cm high), veins on all the leaf blades reticulate, yellow and scabrous margins of leaves and calyx lobes, apex of corolla lobes sub-acute to acuminate and sinus between lobes acute, bluish white to blue colour of corolla, seeds variously shaped, membranous with glandular surface. The new species is described and illustrated here as G. devendrae.
