Explanation:
The seedless vascular plants or the pteridophyte forms one phylum of the plant kingdom. The pteridophyte kingdom can be classified into three groups: the Sphenophytes, the pteridophytes and the Lycophytes.
The Lycophyte group contains about 1000 living species as it is the most primitive group of vascular plants.
