Trees to 10 m tall. Branchlets of current year sturdy, lenticellate, glabrous. Petiole ca. 3 cm, base ca. 4 mm thick; leaf blade elliptic to ovate-elliptic, 25-30 × 8-10 cm, leathery, concolorous, abaxially covered with minute scalelike trichomes, base broadly cuneate and symmetric, margin entire, apex acute and oblique; secondary veins 12-16 on each side of midvein, adaxially slightly impressed, abruptly curving apically, obscure near margin; tertiary veins subparallel. Female inflorescences ca. 3; cupules solitary, scattered on rachis. Infructescence ca. 15 cm, rachis lenticellate, glabrescent, base 0.9-1.4 cm thick. Cupule subglobose, 3.5-4.5 cm in diam., completely enclosing nut, wall 4-6 mm thick and ± woody when dry; bracts subulate, 6-10 mm, woody and multiangular, base 4-8 mm in diam., apex shortly pointed. Nut subglobose but flat at apex, 2.5-3.5 cm in diam., wall ca. 4 mm thick; scar covering more than 3/4 of nut, convex. Fr. Jun-Aug.

Moist places in broad-leaved evergreen forests; circa 1500 m. SW Yunnan [NE India, NE Myanmar]

The nuts were originally described as being separate from the cupules except for the basal part, but the authors found a considerable portion of the nut to be adnate to the cupule.
