Description. Ten Carya specimens show features common to leaflets of extant C. tomentosa . Laminae are mostly obovate, although some are elliptical or ovate and L:W ratios are ~ 2:1. Leaflet size ranges from 5.3–9.9 cm long and 2.2–3.8 cm wide. Bases are mostly symmetrical, although a few are asymmetrical, and most are cuneate. Secondaries are regularly spaced with 45º angles apically and 60º angles basally. Tertiary veins are generally opposite percurrent. Teeth are of one order, uniformly placed 4–5 per cm, and usually occurring along the distal half of the lamina; no teeth or very few small teeth are noticeable basally. Between-teeth sinuses are angular; tooth shapes are straight distally/convex proximally. The principal tooth vein terminates at the tooth apex.

Site occurrence. Scarborough School.

Remarks. Today Carya tomentosa is common in upland sites throughout eastern North America.
