Type
Type: Tanzania, Morogoro District: Uluguru Mts, Kinole, Schlieben 2862 (B†, holo.; BM!, BR!, EA!, HBG!, P!, S!, iso.)
Morphology General Habit
Shrubby herb to 1.2 m tall, basal part of stem creeping; young stems only slightly swollen below nodes, finely sericeous to puberulous
Morphology Leaves
Leaves opposite or in whorls of 3–4 towards apex of stems, dark green above, pale beneath; petiole 1–6 cm long; lamina elliptic to slightly obovate, largest 10.5–20 × 3.5–6.5 cm, apex subacute, concave below the blunt tip, base attenuate, narrowing gradually into petiole; entire to crenate; with 12–15 main lateral veins each side, sparsely sericeous on veins and minutely ciliate
Morphology Reproductive morphology Inflorescences
Spikes quadrangular, 2–4 cm long; peduncle 2.5–5 cm long, sericeous-puberulous; fertile bracts broadly obovate in outline, 8–10 × 8–12 mm, densely pubescent and with long stalked capitate glands, with 3 strong longitudinal veins, no reticulum, apically deeply 3-lobed, lobes triangular, acute to obtuse, sometimes reflexed; bracteoles 5–8 mm long, densely pubescent and with capitate glands in apical 2/3
Morphology Reproductive morphology Flowers Calyx
Sepals acute (lateral obtuse), puberulous towards apex and ciliate, dorsal broadly elliptic, 5–7 mm long, ventral elliptic, 4.5–6.5 mm long, lateral 2.5–3.5 mm long
Morphology Reproductive morphology Flowers Corolla
Corolla pale yellow or yellow with darker orange-yellow centre; tube ± 6 mm long, narrowed above insertion of stamens; limb ± 5 mm long
Morphology Reproductive morphology Fruits
Capsule 6–8 mm long, hairy at apex
Morphology Reproductive morphology Seeds
Seed ± 3 × 2.5 mm.
Ecology
Lowland to montane evergreen forest; 750–1450 m
Note
This was originally thought to be synonymous with C. tridentata, but recent good collections from the Udzungwa Mts with good notes have shown it to be quite distinct. The densely hairy bracts, smaller yellow flowers and smaller fruit separate it. Most significantly the dorsal sepal is 1-veined and 1-toothed pointing to it being closer to C. leucodonta than to C. tridentata.
