In habit and to a great extent in anatomy, the Mesozoic cycadophyta for the most part much resemble the recent Cycadaceae.

If, as now seems probable, the Angiosperms were derived from ancestors allied to the Cycads, it would naturally follow that the Dicotyledons were first evolved, for their structure has most in common with that of the cycadophyta.

The fern-like characters so remarkably persistent in the highly organised cycadophyta of the Mesozoic were in all likelihood derived through the Pteridosperms, plants which show an unmistakable approach to the cycadophytic type.
