Overview

Thelypteris triphylla is a species of the Aspleniaceae family that is widespread in India (West Bengal, South India, Sikkim, Assam, Arunachal Pradesh), Sri Lanka, Myanmar, Thailand, Malaysia, China, Japan, Taiwan, the Philippines, and  Australia. Currently, the presence of Thelypteris triphylla in the population is small. Urbanization, overcrowding and road construction are thought to be the cause of the destruction of this plant's natural habitat.
