Petiole purplish red, ca. 1 cm, glabrous or villous, narrowly winged; leaf blade elliptic to obovate-elliptic, 5.5-10.5 × 2.5-4.5 cm, papery, abaxially yellowish green, appressed pubescent, and densely villous along midvein, adaxially green and glabrous, secondary veins 7-11 on each side of midvein and raised on both surfaces, base broadly cuneate to rounded, margin sparsely serrate, apex abruptly acute to acuminate. Flowers solitary. Pedicel 0.5-3 cm, pubescent or glabrescent, thickened toward apex; bracteoles persistent, ovate, long ovate, ovate-lanceolate, broadly ovate, or subcordate, 2-2.5 × 1-1.3 cm, leaflike, apex abruptly acute, acuminate, or long acuminate. Sepals ovate, long ovate, ovate-lanceolate, broadly ovate, or subcordate, 1-2 × ca. 1 cm, leaflike, outside glabrous or basally sparsely pubescent, apex abruptly acute. Petals white, broadly obovate, 2.5-3 × 1.5-2 cm, outside gray sericeous, apex rounded. Stamens 1.5-2 cm; filaments basally connate, distinct parts sparsely villous. Ovary conical, tomentose; style ca. 1 cm, glabrous. Capsule conical, 1.5-2 × 1-1.5 cm, tomentose, apex rostrate; columella abortive. Seeds obovate in outline, planoconvex, 6-9 × 4-5 mm, margin narrowly winged. Fl. May-Jul, fr. Sep-Nov.

Diagnostic Description
provided by Plants of Tibet
Stewartia sinensis var. sinensis is close relative of Stewartia sinensis var. acutisepala, but differs from the latter in its 0.5-1 cm (vs. 2-3 cm) pedicle, bracteoles and sepals ovate, apex abruptly acute (vs. long ovate to ovate-lanceolate, apex acuminate to long acuminate).
Distribution

Stewartia sinensis is occurring in Anhui, Fujian, N Guangxi, Guizhou, Henan, Hubei, Hunan, Jiangxi, S Shaanxi, E Sichuan, NE Yunnan, Zhejiang of China.
Evolution
provided by Plants of Tibet
Sequences of the internal transcribed spacers of nuclear ribosomal DNA were used to estimate the phylogenetic relationships within Stewartia (Li et al., 2002). Results indicated within Stewartia the New World and the Old World formed well-supported clades. Within the Old World lineage, Stewartia pseudocamellia, S. monadelpha, and S. sinensis formed a clade.

Stewartia sinensis
provided by wikipedia EN
Stewartia sinensis, the Chinese stewartia,[1] is a species of flowering plant in the camellia family Theaceae, native to central and eastern China. It is typically a small deciduous tree or large shrub, commonly growing to about 9 m (30 ft) tall.[2] It is highly regarded horticulturally for the combination of its attractive, cinnamon-colored peeling bark, numerous cup-shaped, fragrant white flowers to 10 cm (4 in) in midsummer, and generally intensely red autumn (fall) foliage. The species also has an attractive multiple-branched growth habit and low maintenance requirements.
In its native forests, S. sinensis has been known to achieve a maximum height of 20 m (66 ft) tall by 7 m (23 ft) broad[3] but it generally does not achieve these proportions in cultivation, where competition for sunlight is less of a concern. This has led to its recommendation for use where larger trees are inadvisable, e.g. under power lines.[4][5][6] When not grown in forested settings, S. sinensis generally takes the form of a multiply-branched, large shrub.
Preferred growing conditions for S. sinensis are similar to those of the more commonly cultivated and closely related Japanese stewartia (S. pseudocamellia), though the latter is somewhat more cold-tolerant. Stewartia sinensis prefers full sun to part shade and moist, well-drained slightly acid soil in a protected location, but may be grown as a specimen tree in climates that do not test its cold-tolerance. It is hardy to USDA zone 5, but it has been suggested that young trees may be more susceptible to cold than older specimens, and should thus be protected during very cold temperatures until they reach mature sizes.[7]
In the UK Stewartia sinensis has gained the Royal Horticultural Society’s Award of Garden Merit.[1][8]
