Cutting the specimen transversely in half revealed a peripheral lining of quartz crystals and a central unmineralized cavity filled with apparent original material including a matrix of thin whitish threads that might be trichomes or fibers, surrounding brown ellipsoidal structures resembling seeds (

. Assignment of the Wagon Bed specimen to this family cannot be absolutely confirmed because the distinctive parietal placentation seen in the London Clay and Clarno specimens is not preserved. However, the overall morphology of the fruit (four-valved, angled capsule, coupled with seeds embedded in a fibrous matrix) closely resembles that of the London Clay and Clarno taxa, although the Wagon Bed specimen is closer in size to the Clarno species.
