Type

Northern Somalia, without precise locality, Révoil 104 (P holo.)

Morphology General Habit

Perennial herb or subshrub

Morphology Stem

Stems up to 12 cm long, ascending to erect, glabrous, usually woody and much branched from the base, angle of branching narrow

Morphology Leaves

Leaves linear to oblong, (3.3–)6.6–10.6(–14.8) x (0.5–)0.8–1.6(–2.5) mm, entire, obtuse or apiculate at the apex, attenuate at the base; petiole 0–4.9 mm long, not twining

Morphology Reproductive morphology Flowers Pedicel

Pedicel 15–20 mm long, usually curved near tip

Morphology Reproductive morphology Flowers Calyx

Calyx-lobes 2.4–2.8 x 0.6–0.8 mm, lanceolate to ovate, acute, with narrowly scarious margins, glabrous

Morphology Reproductive morphology Flowers Corolla

Corolla including spur 11.5–12.5 mm long, yellow, eglandular-pubescent; tube 1.2 mm broad at the mouth; palate lanate; spur 7.4–7.8 mm long, straight and continuing with the tube, exceeding rest of corolla

Morphology Reproductive morphology Fruits

Note

N. stenanthum resembles N. ramosissimum in being a small-flowered shrublet, but differs in its longer spur that is continuing with the tube and exceeds the rest of the corolla. In N. ramosissimum the spur is shorter than to almost as long as the rest of the corolla and it forms an obtuse angle with the tube.
