One has to look at many leaves to start recognising the species of some. There may be a genius who can name every leaf observed, but maybe not.

This Pelargonium alchemilloides leaf photo adds information useful to some: pale stubbly hairs, sunken vein lines, pointy zonal markings following the veins, irregular angularity of the lobes, the base of the leaf positioned in the centre, leaf colour and curvature. All of these and more not noticed or mentioned hold clues for the spark to jump when the next leaf of this variable species growing widespread in Africa is seen on another day.
