Barteria

Shrubs or trees without tendrils; branchlets usually hollow and often inhabited by ants. Leaves alternate or subdistichous, not lobed, elliptic to lanceolate, usually leathery, subsessile or petiole short, often shortly winged and decurrent on branches as a ridge; margin finely crenulate to subentire, set with many small glands; stipules small, caducous. Inflorescences axillary, sessile, either up to 4-flowered fascicles or horseshoe-shaped and 4-9-flowered, or flowers solitary; bracts many, imbricate, brown. Flowers bisexual, large, fragrant, sessile; hypanthium thickish, shallowly cup-shaped. Sepals 5, free, imbricate, large. Petals 5, imbricate, resembling sepals. Corona double: outer one membranous, tubiform, straight or +/- folded, with laciniate margin; inner one low, fleshy, with shallowly lobed margin. Stamens many, nearly hypogynous, arranged +/- in 2 rows; filaments united into a tube in lower 1/4-1/2; anthers 2-thecous, sub-basifixed, oblong-linear. Ovary sessile, placentas 3 or 4, many-ovuled; style single, thick, conspicuous, intruding in stigma; stigma large, hemispherical to obtuse-conical, smooth, entire or distally +/- 3(4)-lobed, often larger than ovary. Fruit coriaceous, perhaps indehiscent but showing 3(4) valve sutures, subglobose, subsessile. Seeds many, ovoid, +/- flattened, arillate; testa crustaceous, minutely pitted.
