Cruiptera, a new Juglandaceous winged fruit from the Eocene and Oligocene of western North America

1991-01-01

Abstract excerpt

Propeller-like samaras from the Eocene and Oligocene of Oregon and from the Eocene of Washington and Wyoming have characters of internal nutlet morphology, sepal and bract configuration diagnostic of the Juglandaceae. These fruits, given the new generic name Cruciptera, consist of a globose unilocular nutlet with incomplete primary and secondary septa, four free epigynous sepals, and four elongate wings that radia...
