The fernery has around 30 species which have tremendous medicinal importance. The species include Hansraj (Adiantum venustum) which has been given importance in Ayurveda as well as in the Tibetan system of medicine as a cure for many ailments.
The fernery also displays some prominent edible species of fern like Lingura (Diplazium esculentum), a popular food item in the hills of Uttarakhand which is considered highly nutritious.
Besides this, the fernery also displays many epiphyte, aquatic ferns and popular and interesting ferns like Vishkanya, Mayurshikha, Boston Fern, Lady Fern, Rock Fern, Basket Fern, Ladder Fern, Golden Fern and Horsetail Fern.
