Division Cycadophyta: Cycads

Internally, cycad stems are similar to those of seed ferns—a thick cortex containing secretory ducts surrounds a small amount of manoxylic (parenchymatous) wood.
Unlike seed ferns, cycad foliage leaves do not bear ovules.
Cycads produce seed cones and pollen cones, each on separate plants.
Seed cones are variable, with those of Cycas revoluta usually considered the most relictual.
Although Cycadophyta was a much larger group with many more species in earlier times,currently, it contains 9 or 10 genera and approximately 100 species.• They are almost all tropical with an unusual distribution; some occur in Cuba and Mexico, others in Australia, still others in southeast Asia or Africa.
