Wikipedia definition
2. CryptogamA cryptogam is a plant (in the wide sense of the word) that reproduces by spores. "Cryptogamae" means hidden reproduction, referring to the fact that no seed is produced, thus cryptogams represent the non-seed bearing vascular plants. Other names, such as "thallophytes", "lower plants", and "spore plants" are also occasionally used.
