Diascia cordata flower from another angle

In this photo the Diascia cordata flower shows the base of its pedicel positioned in the leaf axil. The two spurs are visible on the left close to the calyx lobes, while the corolla lobes are to the right.

The spurs of Diascia flowers contain a kind of oil produced by the plant as so-called pollination currency. This oil is sought by bees of the Rediviva genus for feeding their larvae. At least eight species of these bees have co-evolved with various Diascia flowers, plant and insect serving each other in longstanding, mutually beneficial survival relationships. The oil in exchange for pollination economics works well, because the female bees have long forelegs equipping them for oil extraction from Diascia flower spurs (Manning, 2009; Pooley, 1998; iNaturalist; Wikipedia).
