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
provided by Plants of Tibet
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]

Stewarcja chińska
(
Polish
)
provided by wikipedia POL
Stewarcja chińska (Stewartia sinensis) – gatunek rośliny z rodziny herbatowatych (Theaceae), występująca we wschodniej części centralnych Chin w prowincjach Anhui, Hubei, Jiangxi, Syczuan, Zhejiang[2]. Rośnie tam w cieplejszych, niższych i zalesionych położeniach górskich (850 – 1450 m).
Morfologia
- Pokrój
- Małe drzewko albo duży krzew, trochę mniejszych rozmiarów niż stewarcja kameliowata. Osiąga wysokość do 9 m[3].
- Pień
- Korowina podobna do kory stewarcji kameliowatej, mniej ozdobna i łuszcząca się. Stewarcja chińska jest najczęściej wielopniowa.
- Liście
- Sezonowe, jajowate o ostrych końcach, całobrzegie lub lekko karbowane i ciemnozielone. Przebarwiają się na kolor żółty, czerwony, a nawet purpurowy.
- Kwiaty
- Miseczkowate, wyrastające pojedynczo, średniej wielkości (4 – 5 cm), barwy białej lub kremowej. Nitki pręcikowe żółto-zielone. Pręciki brązowe. Kwitnienie jest długie i zaczyna się dosyć późno (sierpień).
- Owoce
- Drewniejące, pięciokanciaste torebki.
Zastosowanie
Roślina ozdobna sadzona soliterowo lub koło różaneczników, które mają podobne wymagania glebowe. Ma takie same wymagania, jakie posiada stewarcja kameliowata. Jest od niej mniej mrozoodporna, w Polsce bez szkody przetrzymuje mrozy do – 25 °C[3]. Polecana szczególnie dla województw zachodnich, ale może być uprawiana w chłodniejszych rejonach kraju.
