The pale yellow to orange or pinkish red flowers of Hermannia rudis grow solitary or in small clusters at or near branch tips, often on a long enough stalk to nod.
The large, coarse-surfaced sepals are pinkish red to yellow. They are about flat, rounded but with pointed tip and ridged along their midribs.
The rounded, spirally arranged petal tips flare around a narrow corolla opening, protruding only partly and variably from its calyx covering. Flowering happens from late autumn to mid-spring (Burman and Bean, 1985; Bond and Goldblatt, 1984; Andrew, 2017; iNaturalist; http://fernkloof.org.za).
