Abstract
The leaf Pachypteris crassa (Halle) nov. comb. and its pollen organ, Pteruchus petasatus 8p. nov., are described. They are placed in the Corystospermaceae (Pteridospermae), and the limits of the family are discussed with regard to the other ‘Mesozoic pteridospermae’. Information is brought forward on the pollen morphology of the corystosperms.This publication has 1 reference indexed in Scilit:
