Abstract

In the course of an investigation of Carboniferous fructifications and their contained spores, three species of the genus Cordaianthus were studied. The pollen grains from all three species were identical; they consisted of a central body possessing a triradiate scar on the proximal surface, and surrounded by a bladder, which assumed different configurations, depending upon the orientation of the grain. The form genus, Florinites, is probably conspecific with the pollen of Cordaianthus.
