Camellia sasanqua, Subgenus Camellia, Sect. oleifera, Chang Hung-ta and Bruce Bartholomew (1984). Camellias, p.38: Camellia sasanqua Thunb., Fl. Jap., 273. 1784. [Description] This species is very close to C. oleifera only the leaf blades are smaller and slightly thinner, leaf apices obtuse, margins serrulate; sepals glabrous; styles shorter. This species is possibly a geographic variety of C. oleifera. [Distribution] Japan, occasionally cultivated in China. [Synonym] Thea sasanqua (Thunb.) Cels, Cat.

Flowers are white, but may be pink or red in cultivated forms, fragrant, 5.0-7.6 cm in diameter, borne at the tips of shoots and additionally in leaf axils; bud set may be abundant. Perules 8-10, drop as the petals unfold, more or less pubescent on the outside, inside glabrous. Petals 7-8, oblanceolate to obovate, 3.0-3.7 cm long, 1.4-2.4 cm wide, (wild forms) cleft at the tip 3-5 mm, outside of outermost petals sometimes slightly villous, inside glabrous, essen-tially free, not connate or adnate with the androecial column. Androecium glabrous, 1.1-1.6 cm long, widely spreading, free, or outer ones fused up to 3 mm, approximately 100 anthers. Gynoecium 1.1-1.5 cm long, 3 styles, mostly glabrous, range from 10%-85% basal fusion, ovary densely tomentose. Blooming season: autumn to early winter. Capsules irregularly globose to pear-shaped, 1.4-2.6 cm long and 1.3-2.2 cm in diameter, villous or partially glabrous at maturity, 3 locules, rarely 2 or 4, each locule with 1-3 seeds, pericarp wall 1-2 mm thick. Leaves variably elliptic, apex acute or variously acuminate to occasionally cuspidate, base cuneate, 2.6-63 cm long, 0.9-3.2 cm wide (often larger in cultivars), serrulate, teeth spaced 2-6 mm apart, upper surface smooth, hirsutulous along the midrib, lower surface smooth, with a few hairs along the midrib. Petioles 4-6 mm long. Shrub or small tree with a single trunk up to 30 cm in diameter, 10 m tall, stems light brown or tan in color, young shoots heavily villous, older branches gray and smooth. Distribution: Southern Shikoku, Kyushu and islands south of Kyushu, Japan; Specific locality: Shikoku Island near the town of Matsuyama, Japan.
