Ochnaceae

Ochna serrulata, copyright Bernard Dupont.
Belongs within: Malpighiales.

The Ochnaceae are a pantropical group of relatively small trees bearing flowers with deciduous petals (Kanis 1978). Ochna and related genera bear indehiscent drupelets whereas other taxa produce many-seeded capsules.

Characters (from Kanis 1978): Small to medium-sized trees. Leaves alternate, stipulate, simple. Inflorescences lateral and/or terminal, thyrsoid or paniculate, with many bracts at base; pedicels jointed. Flowers regular, bisexual or polygamous; sepals 5, free or more or less joined at base, imbricate, persistent; petals 5, free, contorted, deciduous; staminodes absent or 5–many; stamens 10 or 5; ovary superior, either of five free carpels with one ovule each or three fused carpels with many ovules; styles fused. Fruit either of drupelets or a many-seeded capsule.
