Type: Kenya, Ribe [Ribi] to Galla country, Wakefield s.n. (K!, holo.)
Morphology General Habit
Aromatic perennial soft-wooded shrub or herb to 2 m tall
Morphology Stem
Stems scandent, quadrangular, branched, subglabrous below or with adpressed retrorse hairs, becoming pubescent or densely so above with patent glandular and eglandular hairs and pale or reddish sessile glands
Morphology Leaves
Leaves ascending or spreading, petiolate; blades ovate to elliptic, 8–13 × 4–10 cm, crenate to serrate, apex acute to acuminate, base cuneate, shortly attenuate at petiole, almost glabrous or sparsely pubescent with hairs restricted to veins and margins; petioles 20–70 mm long
Morphology Reproductive morphology Inflorescences
Inflorescence terminal or axilliary, with flowers solitary, spirally arranged, but sometimes opposite at the base of the inflorescence, up to 10 mm apart; bracts linear, 2–8 mm long; pedicels 8–13 mm long
Morphology Reproductive morphology Flowers Calyx
Calyx 5 mm long with long eglandular hairs and shorter glandular hairs on the base and teeth margin and with pale or reddish sessile glands; fruiting calyx (6–)8–11 mm long, tubular, constricted above nutlets with lobes dilating slightly and with the pedicel attached excentrically behind posterior lip; throat bearded, truncate; posterior lip ovate, acuminate to spinescent at apex, curving upwards, not or shortly decurrent; lobes of anterior lip lanceolate, subulate to spinescent at apex, median longer than lateral
Morphology Reproductive morphology Flowers Corolla
Corolla blue or bluish, 9–20 mm long, with scattered hairs and pale or reddish sessile glands; tube 5–10 mm long, strongly sigmoid; posterior lip much shorter than anterior; anterior lip 4–10 mm long, deeply cucullate, horizontal, enclosing stamens
Morphology Reproductive morphology Flowers Androecium Stamens
Staminal filaments fused
Morphology Reproductive morphology Fruits
Nutlets brown, broadly ovoid, slightly flattened, 1.5 mm long, minutely roughened with darker raised areas, producing a small amount of mucilage when wet.
Ecology
Openings and margins of closed evergreen forest; variable 450–2200 m depending on locality
Conservation
Least concern; (EOO 1.33 × 106 km2, 14 collections from 11 localities; AOO 429763 km2 with cell width 231.776 km, number of cells 8, 4 subpopulations based on adjacent cells; 4 subpopulations based on Rapoport distance)
Note
This species represents an intermediate between Plectranthus and Pycnostachys. Specimens from Uganda and Coastal Kenya ( K 7) and Tanzania ( T 3) have shorter corollas (less than 14 mm) than those from the rest of the range.
