    Abstract

    A critical revision of Tectaria (Tectariaceae) from Bangladesh is presented here for the first time based on herbarium collections and field surveys. Eleven species are recognized in Bangladesh, including two narrowly distributed species (T. chattagramica and T. heterocarpa) and nine E & SE Asia-widespread species (T. decurrens, T. fuscipes, T. herpetocaulos, T. impressa, T. ingens, T. multicaudata, T. polymorpha, T. simonsii and T. vasta). The confusions involving species recognition and the application of names in previous literatures are clarified. To facilitate the recognition of species, we provided a key to species and photos for all except T. simonsii. In addition, for each species the diagnostic characters, citation of representative specimens from Bangladesh, brief information on local habitat, abundance and geographical distribution, and notes on affinities are provided.
