Pelargonium coronopifolium flower
Author: Ivan Lätti

The Pelargonium coronopifolium flower is two-lipped. The bigger upper lip has only two petals, the lower lip has three but they are smaller. The five petals are white, pink or purple with darker or white markings (in the case of coloured petals) near the lobe bases of the upper pair, sometimes both colours together. Some white can be spotted in picture on the upper petal bases.
The petals are described as having a teardrop-shape, narrowly clawed at the base, where ear-like protrusions are sometimes present (Bond and Goldblatt, 1984; iNaturalist; Wikipedia).
