Euryops rehmannii leaves may be straight or in-curving and sturdy though needle-like. There is often faint channelling visible on the upper surfaces of the near-cylindrical shapes. The leaf-tips are bluntly pointed, sometimes ending in a mucro or tiny, much thinner protrusion.
The leaves grow scattered or spiralling and sometimes crowded on the upper stem parts (Vlok and Schutte-Vlok, 2015; iNaturalist).
