This Adenium swazicum, the summer impala lily has curiously produced its flowers mainly among and even below the leaves. The plant was photographed in January in the Kruger National Park. The flowers are sometimes a bit paler, the leaves a little wider than seen on this plant.
Yellow and whitish lichen have settled on the stems, cohabiting amicably, not parasitising.
A. swazicum is normally found growing in sandy soil among the grass on brackish flats of the Lowveld (Smith and Crouch, 2009; Onderstall, 1984).
