It may be that the specimen represented in fig. 433 belongs to Cardiocarpus indicus, though this is a mere guess: my belief is that OttoTcaria is a cupular organ that enclosed the base of a seed borne on a Pteridosperm. There is little doubt that as additional data are obtained it will be found that Pteridosperms played no inconsiderable part in the vegetation of Gondwana Land. Strobilites. Schimper and Mougeot.

The type-specimens are long and narrow spikes or loose strobili, 8—16 cm. long and 2—2-6 cm. broad; a stout axis bears spirally disposed bracts 8—10 mm. long attached by a slender decurrent pedicel expanded distally into a fan-shaped laciniate lamina with a convex upper 1 Feistmantel (79) B. p. 30; (81) A. p. 59, PI. xxx. fig. 14; (82) B. p. 43, PI.
