﻿Fig. 70. — Cycadeoidea dacotensis. 

 Ideal view of emergent bisporangiate strobilus just previous to unfolding of the fertile microsporophylls 

 and matuiation and shedding of pollen. The bracts on the left are shown as usually eroded away 

 evenly with the surface of the surrounding armor. Based on the various sections and strobili 

 described in Chapter VII. About natural size. Compare with the restoration of an expanded 

 bisporaugiate strobilus of C. inijens, 6gure 54. and with the plan of the same. Plate IV A.
