Acorns biennial; cup saucer-shaped to cup-shaped, 5-9 mm high × 10.5-17 mm wide, covering 1/4-1/3(-1/2) nut, outer surface puberulent, inner surface pubescent, scale tips tightly appressed, acute; nut ovoid to subglobose, 9.5-16 × 8-11 mm, striate, puberulent, scar diam. 4.8-7 mm. 2n = 24.

Discussion

Quercus ilicifolia reportedly hybridizes with Q. coccinea, Q. falcata, Q. imbricaria, Q. marilandica, Q. phellos, Q. rubra, and Q. velutina.

The Iroquois considered Quercus ilicifolia very helpful in treating gynecological problems (D. E. Moerman 1986).
