In this photo the olive-green to greyish white upper stems of Adenium swazicum can be observed. The leaves are clustered at stem tips, i.e. they are deciduous, new growth appearing annually only at the tips.

The stems of the summer impala lily are smooth, apart from roughness at the nodes from where old leaves had fallen.

This species is suffering somewhat from habitat degradation caused by various human activities.  But being hardy and poisonous, early in the twenty first century it is still only classified as at low risk (Smith and Crouch, 2009; Onderstall, 1984).
