Umkomasia feistmantelii is an unusually large species of Umkomasia from the Early Triassic of New South Wales, Australia.
Umkomasia feistmantelii is found both with cupules enclosing the large seeds and with cupules open and expandede into a star-shaped form.
Umkomasia feistmantelii from the Early Triassic of Australia may have been produced by the same plant as Pteruchus barrealensis (pollen organs) and Dicroidium zuberi (leaves)[1]
