The term bryophyta is used as a collective name to represent a group of plants that includes the mosses (musci), hornworts and liverworts (Hepaticae) growing predominantly in amphibious environment.
Pteridophyta claim a special position as the first land plants. They are also called vascular cryptogams as they possess xylem and phloem. Pteridophytes are nick named as ‘botanical snakes’ as they evolved after bryophytes (botanical amphibians).
