Cycadeoid

“Cycadeoidea dacotensis. Semi-diagrammatic sketch of a flower (bisporangiate cone), cut longitudinally; one sporophyll folded, and one (at the right) arbitrarily expanded. At the center is the apical, cone-shaped receptacle, invested by a zone of short-stalked ovules and inter-seminal scales. The pinnules of the sporophylls bear the compound sporangia (Synangia). Exterior to the flower are several hairy bracts.” -Gager, 1916
