ABSTRACT
Liverworts and mosses are small, low-growing plants, which constitute the phylum bryophyta. Bryophytes, which are phylogenetically placed between vascular plants and algae, form a unique division in the plant kingdom. There are more than 22,000 members of mosses (Bryophyta) in the world. About 2850 bryophytes are reported to have medicinal value. They are now increasingly used for diverse purposes including pollution control and as new sources of pharmaceuticals.
