Orbea variegata and vygie friend

This Orbea variegata flower does not reveal leaves in the photo, but rubs against the vygie or mesemb, Delosperma litorale's leaf and flower parts in their garden container.

The flower has five spreading lobes that bulge beyond the triangular around a dish-like central part or annulus. Transversal wrinkling is conspicuous on the lower corolla lobe parts in picture. All visible floral parts have dark brown to maroon, scattered spots on a creamy yellow background. The spots on the lighter annulus are smaller, although everywhere variable in size and shape. The outer corona in the flower centre comprises five spreading, oblong lobes. They surround a smaller inner corona of two-horned, thread-like lobes, the outer ones nearly erect around the inner ones.  

Some of the floral differences in O. variegata flowers may be associated with hybridisation, which appears to be fairly common in the genus that is much favoured by gardeners (Frandsen, 2017; Gledhill, 1981; White and Sloane, 1937; iNaturalist).
