Description

Family Theaceae

Shrubs or trees , evergreen or rarely deciduous, usually bisexual , rarely dioecious (Eurya) or androdioecious (Ternstroemia) . Stipules absent. Leaves simple , alternate, petiolate or rarely sessile; leaf blade secondary veins pinnate, margin usually serrate or rarely entire . Flowers axillary or subterminal , solitary or sometimes to 3(-10 or more) in a cluster or raceme , pedicellate or subsessile . Bracteoles 2-8 or rarely more, persistent or caducous , sometimes undifferentiated from sepals. Sepals 5(or 6) or rarely more, persistent. Corolla white, red, or yellow; petals 5 or rarely more, basally connate or rarely distinct , adnate to androecium. Stamens numerous , in 1-6 whorls; outer filaments basally ± connate; anthers dorsifixed or basifixed , 2-loculed, laterally and longitudinally dehiscent . Gynoecium 3-5-carpellate. Carpels connate or rarely incompletely connate to nearly distinct. Ovary superior, rarely half inferior, 3-5-loculed, placentation axile or rarely nearly basal; ovules 2-5(to ca. 100) or more per locule; styles distinct to basally connate, rarely completely united . Fruit a loculicidal capsule or indehiscent and drupaceous or baccate , with 1 to many seeds per locule; pericarp woody, leathery, or fleshy ; columella persistent or ± degenerating. Seeds globose , semiglobose, compressed oblong , ovoid , or reniform , winged or wingless; testa bony, leathery, or sometimes with a fleshy red outer layer or sarcotesta (in Anneslea and Ternstroemia), smooth or honeycombed ; hilum umbilicate or linear ; endosperm present or absent; embryo large or small; cotyledons fleshy or thin.

About 19 genera and 600 species: tropical and subtropical Africa, tropical America, E, S, and SE Asia, SE North America, Pacific islands; 12 genera (two endemic) and 274 species (204 endemic) in China.

The greatest species diversity of Theaceae is in S China and adjacent SE Asia.

The two subfamilies of Theaceae used here are sometimes treated as separate families (Theaceae and Ternstroemiaceae) .

Habitat

Ecology: Forested areas have been seriously degraded because of encroaching farming activities, fire and overcutting for wood and charcoal production .[2]
