From the back, the Diascia patens flower shows both shine and glaring hairs. The cup part of the corolla has some deeper dark red with gloss than the lobes, somewhat aligned with veins. The rounded lobes are quite pale and debatably pink or something else. The spurs don't show in this photo angle.
The pedicels are here blackish purple for the most part, covered in the sparse, short stubble that continues on the pale yellow-green bracts, the sepals and the stems. The young, delicate bits are probably better protected against herbivore onslaughts by sporting these stubble coverings; sensible albeit not dignified or floral.
In the case of buds and the spent, corollaless flowers the sepals are closed. The star-shape only shows behind the open flower flaunting a corolla (Vlok and Schutte-Vlok, 2015; Leistner, (Ed.), 2000; iNaturalist; Wikipedia; http://pza.sanbi.org).
