Descriptions

Ochnaceae, N. K. B. Robson. Flora Zambesiaca 2:1. 1963

Morphology General Habit
Shrubs, shrublets or perennial to annual herbs, completely glabrous.
Morphology Leaves
Leaves petiolate to sessile; lamina with margin serrate, incrassate; stipules with laciniate margins, longitudinally striate, free, persistent.
Morphology Reproductive morphology Inflorescences
Inflorescence paniculate to racemose and terminal or reduced to solitary flowers in the axils of foliage leaves; pedicels articulated at or above the base.
Morphology Reproductive morphology Flowers Calyx
Sepals 5, quincuncial in bud, green with pale margin, persistent, not enlarging or changing colour in fruit.
Morphology Reproductive morphology Flowers Corolla
Petals 5, white to pink, not unguiculate, deciduous.
Morphology Reproductive morphology Flowers Androecium
Androecium of (2) 3 whorls; outer staminodes ? in a continuous ring or in 5 antisepalous groups or individuals, short, filiform and capitate or narrowly petaloid or sometimes absent; inner staminodes 5, antipetalous, petaloid, free, forming a pseudo-corona; stamens 5, antisepalous, free, with anthers dehiscing longitudinally and short filaments.
Morphology Reproductive morphology Flowers Gynoecium Pistil
Ovary with 3 parietal placentas (or axile at the base), each placenta bearing ? ovules in two rows; style simple, slender; stigma not enlarged.
Morphology Reproductive morphology Fruits
Fruit a capsule with 3 septicidal valves.
Morphology Reproductive morphology Seeds
Seeds ?, small, with punctate testa and abundant endosperm; embryo straight, about half as long as the seed, isocotylous.
