Pelargonium crithmifolium fleshy leaf

The soft, fleshy midrib of the Pelargonium crithmifolium leaf is channelled along the upper surface, not all the way down on the petiole. The channelling continues onto the wedge-shaped, flat to curved-in leaf lobes that grow opposite and spaced.

These lobes, angularly toothed (or sub-lobed) and also fleshy to succulent, differ in number, size and their typical asymmetry. If the lesser lobes were fingers, it would mostly be clear where the thumb is.

Leaf size on older plants and during drier seasons will often be inferior to the leaf in picture, its lushness also missing (Vlok and Schutte-Vlok, 2015; Le Roux et al, 2005; iNaturalist).
