Type: Kenya, Trans-Nzoia District: S Cherangani, Symes 293 (EA!, holo. K!, iso.)
Morphology General Habit
Perennial suffrutex 0.2–0.6 m tall with several stems arising from a woody rootstock, not reported to be aromatic
Morphology Stem
Stems erect or ascending, rarely decumbent, quadrangular, purplish above, with few leaves but also producing more leafy sterile shoots, pubescent with glandular or eglandular hairs, these sometimes retrorse, and with yellowish sessile glands
Morphology Leaves
Leaves spreading, slightly succulent, shortly petiolate or sessile, often folded along midrib on drying, sometimes with fascicles of younger leaves in axils of blades; blades narrowly trullate, elliptic or obovate, 1.5–2.5(–4) × 0.3–1.5 cm, with leaves of sterile shoots up to 4 cm long, entire, subentire or shallowly crenate, apex rounded or obtuse, base attenuate, densely pubescent, with yellowish sessile glands; petiole 0–3 mm long
Morphology Reproductive morphology Inflorescences
Inflorescence lax with 6–10-flowered verticils 15–30 mm apart in fruit; cymes sessile or with a very short peduncle, 3–5-flowered, dichasial at first branch and sometimes producing two lateral condensed cincinni; bracts lanceolate, 2 mm long, erect above forming an inconspicuous terminal coma, deciduous as buds start to develop, more rarely ovate to 5 mm long, deflexed and persistent until fruiting; pedicels 3–5 mm long, ascending, shortly flattened, distally curved
Morphology Reproductive morphology Flowers Calyx
Calyx 3–4 mm, sparsely pubescent, with red and yellowish sessile glands, purplish; fruiting calyx 7–8 mm long, shortly tubular and with pedicel attached excentrically behind posterior lip; throat truncate, densely villose; posterior lip obovate, shortly apiculate at apex, curving upwards, decurrent; anterior lip 4-lobed, lateral lobes deltate, median lanceolate, longer than lateral
Morphology Reproductive morphology Flowers Corolla
Corolla white to purple, 14 mm long, with scattered red glands or hairs on lobes; tube 5–7 mm long, sigmoid; posterior lip much shorter than anterior; anterior lip 7–9 mm long, finally horizontal, deeply cucullate, enclosing stamens
Morphology Reproductive morphology Flowers Androecium Stamens
Staminal filaments fused
Morphology Reproductive morphology Fruits
Nutlets dark brown, with dark gland dots, broadly ovoid, slightly flattened, 1.5 mm long, smooth, producing copious speckled mucilage when wet
