PTERIDOPHYTES Pteridophytes in the broad interpretation of the

term are vascular plants (plants with xylem & phloem) that reproduce & disperse via spores, because they produce neither flowers nor seeds, they are refered to as CRYPTOGAMS.

The 305 genera & 13,000 species of pteridophytes found throughout the world.

The pteridophyte includes Clubmosses,SPike-mosses, Quilworts,Horsetails,Ferns.

INTRODUCTION

Most pteridophytes are decorative. They are grown for the unusually beautiful foliage, often compact and graceful appearence.

They broadly divided into CLUBMOSSES, HORSETAILS, FERNS.

Pteridophytes are most commonly found in damp or humid and shaded enviroment

ornamental pteridophytes

Clubmosses are a group of plants in Lycopodiophyta, which are the most ancient group of land plant.

The clubmosses are structurally similar to the earliest vascular plants, with small scale like leaves,homosporous spores born in sporangia at the base of leaves, branching stem and generally simple form.

A low growing variety with small leathery fronds. The name of the genus is from greek means

WING.

PterisFAMILY-

PTERIDACEAE

The ornamental pteridophytes are very important for us;

FRAGRANCE –Many ornamental plants are chosen because they appeal to the sence of smell,in addition to their visual appeal.

CLEAN AIR-Without plants we couldnot have clean air to breath because plant create oxygen during photosynthesis.

Keeping ornamental pteridophytes has been shown to improove the air quality to remove the house air pollution like tobacco & other.

CONCLUSION

Ornamental pteridophytes are used in landscapes and throughout the home to beautify the

surroundings.
