Abstract
The confused species, Isoetes sahyadriensis Mahab., was apparently based on a mixture of two species in the area. It is lectotypified here from the only surviving authentic material, which is an immature plant, and epitypified in the sense of the reticulate-spored small species of India with complete velum. Suggested synonymy of the four distinct species known India is given.
