Pelargonium desertorum flower showing its stigma

The five-branched, purplish stigma of the Pelargonium desertorum flower in picture is noticeable, while not one anther is present on the white, shrivelling filaments around the style base. This means that the flower is getting old, having lost its anthers. Pelargonium flowers may have up to ten stamens. In this species up to seven of them are usually fertile.

A couple of silvery margined, hairy sepals are present behind the corolla, dull olive green down their strongly recurved, inner surfaces.

The pair of white upper petals have reddish purple markings, spaced and spotty down the centre of their lower parts. The three nearly oblong lower petals that are unmarked here may sometimes have a small purplish patch right at the base, or only a diffuse purplish tinge (Williamson, 2010; iNaturalist; www.namibrand.com).
