Pteridophytes (Ferns)

Abstract

Pteridophytes (vascular cryptogams or ferns and fern allies) comprise about 12 000 species of primitive vascular plants; they do not produce flowers or seeds and reproduce instead via spores. They occur in most terrestrial habitats and also in some aquatic communities. Some species are very beneficial to humans, but the group also contains important species of weeds.

Keywords: pteridophyte; fern; fern ally; vascular cryptogam; plant; botany
