乔木，高9-15枝、叶无毛，干后颜色苍暗。叶厚纸质，狭长椭圆形或披针形，长9-17厘米，宽2-4厘米，顶部渐尖，基部楔形，下延，全缘，中脉在叶面凸起，但中央裂槽状凹陷，侧脉每边13-16条，纤细，支脉几不可见，两面近于同色或二年生叶的背面略带苍灰色；叶柄长1-2厘米。雄穗状花序三数穗排成圆锥花序，有时单穗腋生，花序轴被稀疏短柔毛；雌花序2-4穗聚生于枝顶部；雌花通常3朵一簇，花柱长1-1.5毫米。果序轴粗4-6毫米，很少达10毫米；壳斗近圆球形，或高过于宽，顶部突然狭窄并稍伸长如乳头状，高15-30毫米，宽15-28毫米，全部包坚果，很少包着坚果绝大部分，壳壁上部厚达2毫米，下部达4毫米，小苞片阔三角形或四边菱形，近顶部的为长三角形，覆瓦状排列，顶部的弯向凹陷的壳斗口部，中部以下的常与壳壁离生且稍扩展；坚果扁圆或圆球形，径14-24毫米，栗褐色，果脐凹陷，深0.5-1毫米，口径13-16毫米。花期7-9月，果次年8-11月成熟。
产福建西南部、广东、广西、贵州东南部、云南东南部。生于海拔150-1 200米山地杂木林中，湿润地方较常见。模式标本采自香港。
壶壳柯及其变种金平柯和沙坝柯三者与厚斗柯近缘，其间的区别或在于叶背是否被毛，或在于壳斗是否全包坚果，或在于小苞片的形状（鳞片状或短线状）。
分布于广西东北部和贵州东南部的其叶片宽达6厘米，嫩叶及嫩叶背面中脉基部两侧有甚稀疏而早脱落的细柔毛。树皮暗黑褐色，不开裂，内皮淡紫褐色，脊棱不甚突出，材身的槽棱较圆滑，木材淡茶褐色或略带暗紫色，颇坚实。

Quercus elizabethiae Tutcher, J. Bot. 49: 273. 1911; Pasania elizabethiae (Tutcher) Schottky; Synaedrys elizabethiae (Tutcher) Kudo.
Trees 9-15 m tall; branches and leaf blades glabrous. Petiole 1-2 cm; leaf blade narrowly oblong to lanceolate, 9-17 × 2-4 cm, thickly papery, concolorous to ± glaucous abaxially, base cuneate and decurrent on petiole, margin entire, apex acuminate; secondary veins 13-16 on each side of midvein, slender, evident; tertiary veins abaxially inconspicuous. Male inflorescences 3-many in a panicle, sometimes solitary in axils of leaves; rachis sparsely pubescent. Female inflorescences 2-4 congested at apex of branches; cupules usually in clusters of ca. 3. Infructescence rachis 4-6(-10) mm thick. Cupule subglobose, 1.5-3 × 1.5-2.8 cm, usually enclosing nut, apically abruptly narrowed and slightly elongated into a nipple, wall apically ca. 2 mm thick and basally to 4 mm thick; bracts imbricate, broadly triangular to rhomboid, apical ones incurved. Nut depressed globose to subglobose, 1.4-2.4 cm in diam., wall ca. 1 mm thick; scar 1.3-1.6 cm in diam., concave. Fl. Jul-Sep, fr. Aug-Nov of following year.
* Mixed mesophytic forests, frequent in moist places; 100-1200 m. SW Fujian, Guangdong, Guangxi, SE Guizhou, SE Yunnan
