There are 4 divisions: 
1. Psilophyta 2. Lycophyta 3. Sphenophyta and 4. Pterophyta
1. Psilophyta:
Psilotum comes under psilophyta. 
2. Lycophyta (Club moss or spike moss)
3.Sphenophyta (Horse tail)
4.Pterophya (Ferns or Filicophyta)

Dear student
Pteridophytes (ferns and lycophytes) are free-sporing vascular plants that have a life cycle with alternating, free-living gametophyte and sporophyte phases that are independent at maturity. The body of the sporophyte is well differentiated into roots, stem and leaves
Good Luck
