A Pachypodium namaquanum leaf has an about straight midrib apart from some gentle curving and maybe a twist at its tip. This contrasts strongly against the elaborately undulating but entire margins that seem to writhe and curl along the slightly upturned lateral blade halves. The elliptic blades are thick, dull grey-green and hairy, the hairs star-shaped.

The pale yellow or creamy midrib is thick near the base and bulging from the lower leaf surface, tapering markedly in its upper part. Parallel, spaced lateral veins ascend to the margins from the midrib.

The deciduous leaves spread in a few rows around the flowered top. They are present during the winter growing season, concurrent with the commencement of flowering (Frandsen, 2017; Le Roux, et al, 2005; Eliovson, 1990; Wikipedia).
