New branchlets glabrescent, leaf buds pubescent. Leaf blade elliptic, 8–18 × 4–6.5 cm, glabrous on both surfaces, base cuneate. Flower 3.5–4.5 cm in diameter. Pedicel 7–15 mm long, glabrous. Sepals 3–5 × 4–8 mm, outside glabrous, inside sericeous. Petals outside glabrous, inside sericeous or glabrous. Ovary glabrous. Style apically 3-lobed, glabrous. Fruit 3–4 cm in diameter; pericarp 0.5–2 mm thick. Fl. October to December, fr. June to October.

Camellia gymnogyna has larger flower and fruit which can be distinguished from other tea plants that bear similar glabrous ovary and apically three-lobed style, such as C. costata and C. leptophylla S. Ye Liang ex Hung T. Chang

Camellia gymnogyna has most recently been assessed for The IUCN Red List of Threatened Species in 2015. Camellia gymnogyna is listed as Least Concern.
