Doneggia complura G.W.Rothwell

Original diagnosis/description

Characters of the genus as those of the family. Sporangia borne on the lobes of laminar pinnules. Numerous sporangia per sorus, attached to an expanded receptacle region below a vein. Sporangia oblong with a bluntly rounded tip and a short, broad stalk; round or oval in transverse section. Spores radial, trilete, subtriangular in polar view.


The generic name Doneggia is proposed in honor of Professor Donald A. Eggert, University of Illinois at Chicago Circle, for the significant contributions he has made to our understanding of pteridophyte structure and evolution.
