What are the spurs on a diascia flower?

The two spurs found on the back of a Diascia flower (from which it gets the common name twinspur) contain a special oil, which is collected in the wild by at least 8 species of bees of the genus Rediviva. The bees appear to have coevolved with the plants, as the females have developed unusually long, hairy forelegs with which they collect the oil from Diascia spurs to feed their larvae (and sometimes to line their nests with). The spurs vary in average length from 5.3 millimetres (0.21 in) to as much as 13.9 mm (0.55 in), mainly between species (although those of D. capsularis can vary widely between populations); the bees' forelegs vary similarly. The spurs of Diascia longicornis are about 25 mm (0.98 in) in length, but the existence of a suitably equipped pollinator, Rediviva emdeorum, with forelegs of the same length, was only confirmed in the 1980s. Rediviva longimanus has also been observed pollinating D. longicornis in the Western Cape.
