The twiggy Lycium afrum side-branchlets are stiff, unyielding in contact (which would be ill-advised).
The green-grey leaves are slightly succulent to thinly leathery, sometimes covered in a faint bloom. Some leaves are straight, some curving, the curvature not described as sickle-shaped as they sometimes curve in the direction of one of the blade surfaces, sometimes to one of the margins (Privett and Lutzeyer, 2010; Manning, 2007; Manning and Goldblatt, 1996; Bond and Goldblatt, 1984; iNaturalist).
