Lowest pteropsida {fern}| make no seeds or flowers. Ferns make haploid spores at specialized-leave bottoms. Spores drop to ground and grow into gametophytes, which make eggs that cross-pollinate to form new plants. Regular ferns have perennially erect stems, rhizomes with roots, and compound leaves in buds. Ferns have no xylem.
