Information
Shrub to 1 m., flowering mostly on relatively short lateral branches; branchlets glabrous to minutely puberulous with short stiff spreading hairs. Leaves mostly subopposite, but smaller, more obovate and more crowded at the base of lateral shoots; petiole 8–15 mm. long; lamina lanceolate to oblong-elliptic, 5–10 cm. long, 1.5–4 cm. wide, acute or obtuse at the apex, cuneate or rounded at the base, glabrous, with 6–8 pairs of lateral nerves, the lower ones sometimes strongly ascending. Umbels 6–8-flowered; peduncle 3–6 mm. long, puberulous; pedicels 2–5 mm. long, puberulous; bract-limb ovate-triangular, 1.5–2 mm. long, pointed or truncate. Receptacle 1.5–2 mm. long, thinly puberulous; calyx 0.3–0.5 mm. long, broadly toothed. Corolla 3.5–3.8 cm. long, tube red, lobes yellow with purple-brown tips, puberulous on head of bud (lobes), sparsely hairy on tube (the longest hairs on the constriction and basal swelling reddish and deflexed); apical swelling of bud cylindrical, 4–4.5 mm. long, 2 mm. in diameter, with flattened thumb-like appendages from near the top of each lobe giving the form of a crown; basal swelling ovoid-globose, 3.5–4 mm. across, narrowed for 3–5 mm. above; lobes erect, 7 mm. long, the upper expanded part lanceolate, 4–4.5 mm. long, 1 mm. wide, hardened inside and slightly thickened towards the base, spurred outside.

Notes
The strikingly crowned corolla-buds are an unusual feature for species of this genus which have vents, compared to the heads typical of Tapinanthus. M.G. Gilbert has noticed in Ethiopia that A. heteromorphus (A. Rich.) Polh. & Wiens (a close ally of A. musozensis ) tends to have flowers opened by birds squeezing the heads rather than slitting the corolla open through the vents, and similar signals may be given by this species.
