Introduction to Pteridophytes: Pteridophytes constitute a significant and important group in the plant kingdom. Pteridophytes, also known as ‘vascular cryptogams’ and ‘ferns and fern allies’, comprise about 12000 species of vascular plants that do not produce flowers or seeds, reproducing instead via the production of spores. This means that their leaves originated from the emergences of the stem surface, and therefore are more similar to moss leaves than any other leaves of pteridophytes and seed plants. 3. ... anceinclassifyingpteridophytes,fortheshape,size,arrange-mentandvenationofleaves(andevenpresenceorabsence … The diversity increases at tropical and subtropical latitudes.
