Nemesia fruticans flower colour may also be deeper like this. The upper lip has four similar, oblong and round-tipped lobes that diverge at their tips. Dark vein lines are nearly parallel, petering out before they reach the upper margins. At the base there is a narrow yellow part on the inner pair of these lobes.
On the lower lip the basal yellow part covers a wider area, mainly upon the pair of oblong bulges and ending in a white fringe. The large lower lip is pronouncedly notched at its tip and spreads flatly around the bulge area.
The protrusion on the left of the flower looks like a closed calyx from which the corolla has dropped off. A whitish style still remains attached to the enveloped ovary that is becoming a fruit (Vlok and Schutte-Vlok, 2015; Manning, 2009; iNaturalist).
