Cyathea brunoniana is a majestic plant which is fast disappearing from its natural habitat. The tree ferns mostly grow in warm humid environment in shady forest floor. Cyathea brunoniana is reported from some places of North East India including Assam, Arunachal Pradesh, Manipur, Meghalaya, Mizoram and Sikkim from time to time but not from Tripura.
