Ridges in young fruits often terminate only a few mm apart, resulting in hollow enclosures protecting the exterior inner cupule. | Cupule sparsely covered with simple, short, curled thorns set in 3-5 lines. | Cupule sparsely covered with woody, branched, curved spines. | Cupule sparsely covered with woody, branched, curved spines. | Cupule covered with tufted, erect, simple thorn-like structures. |

| 4. Acorn shape (ripe), position | Acorn globose, sessile and solitary. | Irregularly globose, sessile and clustered (sometimes fused). | Globose, stalked and solitary. | Irregularly globose or bilobed, semi-stalked to sessile and solitary. | Asymmetrically depressed subglobose, sessile solitary or in pairs. |

| 8. Nut shape, size and scar (l × w) | Rectangular and flattened at the base, 2.5-2.9 cm × 2.3-2.4 cm, scar 2.3-2.5 × 2.3-2.4 cm. | Ovoid, emarginate, concave at the bottom, 1 cm × 1 cm, scar 0.2-0.3 × 1 cm. | Ovoid and asymmetrically compressed, 2-3 cm × 1 cm, scar unreported. | Ovoid, asymmetric and slightly curved, 3 × 1.5 cm, scar unreported. | Asymmetrically depressed subglobose, 3.5-4 cm × 2-3 cm, scar basal 1 cm diam. |
| 9. Leaf shape, size (l × w) | Elliptic, with cuneate base and acute apex, (11)13-17(19) × (2)3.5-5(6) cm. | Obovate, obovate-oblong, oblong or lanceolate, 7-17 × 5-7 cm. | Elliptic, oblong or obovate, 10-25 × 3.2-6.3 cm. | Lanceolate or oblong, 10-20 × 3-6 cm. | Oblong, elliptic or obovate, 10-20 × 3.5-8 cm. |
