    Type
    Type: Ethiopia, Mt Kubbi, Schimper 418 (K!, holo.; B, BM!, BR, G, GOET, HAL, HBG, JE, L, M, MPU, OXF, P, S, UPS, Z, iso.)
    Habit
    Erect perennial herb or undershrub, up to 60 cm tall.
    Stem
    Stems sparsely branched, pubescent, glandular, viscid
    Leaves
    Leaves dense on the distal part of the stems, oblong to elliptic, (5–)15–55 mm long, (3–)4–14 mm broad, cuneate at base, apex obtuse, margins crenate, pubescent, ± glandular
    Inflorescences
    Inflorescence spicate, the flowers spreading; bracts somewhat divaricate, similar to leaves, glandular-pubescent; pedicels 2–5 mm
    Calyx
    Calyx green, 10–15 mm, unequally 5-lobed to 1/3 (lateral clefts) or 2/3 (median clefts) of its length; lobes ovate-oblong, acute to obtuse, median one or both lobes with small irregular lobes on one margin, glandular-pubescent
    Corolla
    Corolla lemon yellow, often with reddish veins, tubular; tube straight, 15–23 mm, glandular-pubescent outside and inside, expanding above into 5 lobes; lip of 3 lobes, rounded, deflexed, 7–8 mm, margins erose, dorsally glabrous; galea 7–8 mm, hairy at the top
    Stamens
    Stamens attached to the top of the corolla tube; filaments 4–5 mm, with small scale-like papillae along the length; anther ± 3 mm, at right angles to the filament, bearded along the anther suture, acute at apex
    Gynoecium
    Ovary oblong, ± 5 mm; style ± 30 mm, curved distally, puberulous; stigma clavate
    Fruits
    Capsule ovoid, 10–12 mm long, 5–7 mm in diameter, short to long villous to ± glabrescent
    Seeds
    Seeds 1–2 mm long, broadly winged.
    Note
    Molau (op. cit.) recognizes two subspecies based on the length of the corolla, and the length:width ratio of leaves. Whereas the length of the corolla tube mostly holds true in Flora area, the leaf length:width ratio is variable. I have followed Molau in the treatment of the subspecies, as subsp. macrophylla is found only in a small part of the Flora area (Ruwenzori and Virunga Ranges of Uganda) extending to Congo-Kinshasa and Rwanda.
