Huernia namaquensis responding to sun

Not only perceived in a different light, these Huernia namaquensis flowers lack the purple spots. Sunlight emphasises the presence of the central bowl or broad tube of the corolla within which the components of the corona appear like mechanical engineering parts for some mythical machine.

The surface papillae upon the pale corollas are hardly visible, less so than the dull white, straight vein lines converging into the lobe tips. The secondary lobe tips or teeth are short, but sharply pointed in the dips or sinuses. In botany, a sinus is a space or indentation between two lobes or teeth, usually on a leaf, in this case upon the corolla margin of the flower.

The flowers face outwards, close to the ground, the roughly erect green stems behind them (Williamson, 2010; White and Sloane, 1937).
