Cycas Lecture by Dr. Anupama Goyal.

Cycas is an evergreen , palm like small tree. It grows in xerophytic habitats. The sporophytic plant body of Cycas is differentiated into roots, stem and leaves. The roots are of two types : Normal tap roots and coralloid roots. The leaves are also of two types i.e. dimorphic . The assimilatory leaves or foliage leaves and Scale leaves . The asexual reproduction takes place by the formation of sporangia and spores . The sporangia are arranged on the lower side of the microsporophyll in definite groups called sori. Sexual reproduction occurs by the formation of antheridia and archegonia.
