Characteristics of Ferns and Horsetails
- Megaphylls. Leaves have branching veins of vascular tissue.
- Rhizomes. Asexual propogation of the sporophyte through underground stems.
- Homospory. Haploid spores grow into bisexual gametophytes that produce both antheridia and archegonia. Note: There is an order of aquatic ferns (Salviniales, to which the water fern genus Azolla belongs) that are heterosporous.
