M a t e r i a l s t u d i e d. Bracts and fruitlets PA 1420.1,

D e s c r i p t i o n. The bracts are tripartite at the very apex, narrow, up to 10 mm long, 2 mm wide, fruitlets double winged, 3 mm long, 4 mm wide.

D i s c u s s i o n. The bracts and fruitlet associated with the above foliage obviously belong to the same birch foliage as mentioned above. Bůžek et al. (1976) assigned them to the same fossil species as leaves co-occurring in the diatomite of the locality Markvartice.
