- Habit
- Small shrubs with a single haustorial connection, glabrous Small shrubs with a single haustorial connection, glabrous.
- Leaves
- Leaves subopposite, shortly petiolate; nerves few, spreading to strongly ascending, sometimes obscure Leaves subopposite, shortly petiolate; nerves few, spreading to strongly ascending, sometimes obscure.
- Flowers
- Flowers 2–6 in shortly pedunculate axillary umbels; bract shortly cupular, with a small limb, gibbous or spurred dorsally Flowers 2–6 in shortly pedunculate axillary umbels; bract shortly cupular, with a small limb, gibbous or spurred dorsally.
- Calyx
- Calyx cupular to shortly tubular, split by expanding corolla Calyx cupular to shortly tubular, split by expanding corolla.
- Corolla
- Corolla straight to bent in bud, 5-merous, with a short tube, yellow to red, banded green or white; lobes linear-oblanceolate, often somewhat coherent, but without a marked V-split in the tube, reflexed about the middle Corolla straight to bent in bud, 5-merous, with a short tube, yellow to red, banded green or white; lobes linear-oblanceolate, often somewhat coherent, but without a marked V-split in the tube, reflexed about the middle.
- Style
- Style filiform; stigma capitate
- Note
- Closely related to Oncocalyx, but with a very short corolla tube without a V-split on one side; the common species, S. rhamnifolia, has characteristic flower buds bent near the base.
- Distribution
- Two species in east and south-central Africa along the coast and extending into the mountains in drier types of forest.
- Stamens
- Stamen filaments attached at base of corolla lobes, erect and filiform below, upper part sometimes slightly thickened and inrolled at anthesis, with a small tooth on front of the anther; anthers linear, 4-thecous, truncate.
