Bracts sessile, erect, elliptic-lanceolate, 6–11 mm long, 1–2.5 mm wide
Morphology Reproductive morphology Flowers Calyx
Calyx  ± 5 mm long, hyaline with 5 purplish pubescent ribs, 2–3-toothed
Morphology Reproductive morphology Flowers Corolla
Corolla purplish brown outside and cream inside with 5 orange spots round the throat; tube slender, 10–12 mm long, ± glandular outside, glabrous inside, greatly exceeding the calyx; limb cup-shaped and regular with 5 oblong lobes 1.5–2 mm long with entire, rounded apex

Ecology
Afro-alpine zone, rocky ground with thin soil; ± 3800 m
Conservation
Vulnerable, VU D2 with less than 5 locations and the species has not been re-collected for almost 40 years
Note
Since both collections are from the same altitude and zone, the species is expected to occur in the same zone on Mt Kenya, but there are no collections from there so far.
Distribution
Range: Not found elsewhere Flora districts: U3 T2
