Family Ochnaceae

Trees and shrubs , rarely herbs. Leaves alternate, simple , rarely pinnately compound , petiolate ; stipules entire or sometimes lacerate , persistent or caducous ; leaf blade margin dentate , serrate or rarely entire; veins pinnate. Inflorescences terminal or axillary , cymose or racemose, rarely 1-flowered. Flowers generally bisexual , actinomorphic or more rarely zygomorphic, bracteate ; pedicels articulated. Sepals (2-4) 5(10-15), free or more rarely united , imbricate or valvate . Petals (3-) 5(-8), mostly free, clawed to sessile, contorted or imbricate. Stamens 5-10 or numerous ; filaments generally free and persistent, or anthers sessile; anthers basifixed , longitudinally dehiscent or poricidal ; staminodes present or not, sometimes persistent, awl-shaped , spatulate , or petaloid , sometimes connected into a tube . Gynoecium (2 or) 3-5(-15) -carpellate, gynophore present or rarely absent; ovary superior, entire or deeply lobed , generally long styled; placentation basal, axile or parietal , rarely laminar ; ovules 1 or 2 or numerous per locule; stigma entire or sometimes shortly divided at apex. Fruit fleshy or non-fleshy, generally a septicidal capsule, rarely a nut with accrescent sepals or a drupe, or separating into up to 15 blackish drupelets on a colored accrescent receptacle. Seeds endospermic or non-endospermic, winged or not; germination phanerocotylar or cryptocotylar ; embryo usually straight, more rarely curved .

About 27 genera and ca. 500 species: tropical zones, mainly in the Neotropics; three genera and four species (one endemic) in China.[1]

Genus Ochna

Small trees or shrubs . Stipules small, intrapetiolarly united , deciduous; leaf blade simple , margin generally serrate, rarely entire; secondary veins curved upward, especially near margin, not joining in a submarginal vein . Inflorescences branched, sometimes corymbose . Sepals (4 or) 5, completely enclosing floral bud, margins entire, often accrescent and colored in fruit, persistent . Petals 5-12, yellow or rarely orange or white, contorted. Stamens numerous , 2- or more whorled ; filaments short or elongate , persistent; anthers poricidal or more rarely longitudinally dehiscent . Ovary deeply lobed , 3-15-locular; ovule 1 per locule; style gynobasic , slender; stigma generally slightly lobed. Drupelets 3-10(or 15), black, inserted on accrescent receptacle. Seed non-endospermic; embryo straight or curved.

About 85 species: mainly in tropical Africa, a few species in tropical Asia; one species in China.[2]
