What are Pteridophytes?
The pteridophyte is derived from two words; Pteron, meaning feather in Greek, and phyton means herb. So, this name was originally given to those plant groups that had well shaped feather like leaves. These plants carry no flowers or seeds. Therefore, they are also called Cryptogams, simply because their means of reproduction are secret. A cryptogam, Cryptogamae scientifically is a plant (in the broad sense of the word) which reproduces by spores, without flowers or seeds.
“Cryptogamae” taken from Greek, that is, kryptos meaning “hidden” + gamae meaning “to marry.” The hidden reproduction refers to the fact that cryptogams represent the non-seed – bearing plants without the production of seeds. We are in reality the first developed group of plants with a vascular tissue network for water and food transport. They ‘re found mostly in dark, damp areas. They cover ferns and horse-tails. The ferns are mostly used as ornamental plants.
