Flower morphology of the Geraniales is rather conserved. They are usually perfectly pentamerous and pentacyclic without fused organs besides the carpels of the superior gynoecium. The androecium is obdiplostemonous. Only a few genera are tetramerous (Francoa, Tetilla, Melianthus). In some genera some stamens (Pelargonium) or a complete whorl of stamens are reduced (Erodium, Melianthus). In the genera Hypseocharis and Monsonia there are 15 instead of the usual ten stamens. Most genera bear nectariferous flowers.[1] The nectary glands are formed by the receptacle and are localised at the bases of the antesepalous stamens.[1][2]

23,420 species of vascular plant have been recorded in South Africa, making it the sixth most species-rich country in the world and the most species-rich country on the African continent. Of these, 153 species are considered to be threatened.[4] Nine biomes have been described in South Africa: Fynbos, Succulent Karoo, desert, Nama Karoo, grassland, savanna, Albany thickets, the Indian Ocean coastal belt, and forests.[5]
