Live on damp forest floors & dry areas
Become dormant when moisture = scarce
Sporophyte generation has roots, stems, leaves

7. PTEROPHYTA Thick main stem underground = “rhizome” Leaves = “fronds”
Leaflets = “pinnae”
First plant to evolved leaves with branched veins
Sporangia produce spores
Sorus or sori = clusters of sporangia
