Paleobotany and the Evolution of Plants
First, cycadeoid ovules are small (up to 3 mm long), unlike the much larger seeds
of the medullosan pteridosperms. Although debatable, the nucellus of cycadeoid
ovules is said to be fused with the integument except in the apical region.

New Organic Architecture: The Breaking Wave
The frond-borne pollen organ of some Paleozoic seed fern has been postulated
as the progenitor of the Mesozoic cycadeoid cone (Delevoryas, 1968a, 1968b).

Based on the microstructures of the laminae and petiole, the plant organs found
in the nodules appear to be most comparable to members of the Cycadeoi- dales
and suggests that at least one species of cycadeoid provided browse for ...
The prototype of an entomophilous flower probably developed while the early

We cannot quite ignore the view stressed by Gupta, that Homoxylon
