Riccia sahyadrica
Riccia sahyadrica is a species of liverwort described from the Western Ghats of Peechi-Vazhani Wildlife Sanctuary of Kerala. Its name is derived from the Malayalam word "Sahyadri" for the Western Ghats. It is characterized by the photosynthetic region confined to the lower half of the thallus. In "Riccia" members, the photosynthetic region is on the upper half of the thallus. Only one other species, "R. caroliniana" from northern Australia, is known with this feature.
