Type
Type: Congo-Kinshasa, Ruwenzori [Runssoro], Stuhlmann 2424 (B†, holo.)
Morphology General Habit
Erect or scrambling shrubby herb or shrub to 3(?–5) m tall, often thicket-forming; young branches glabrous or with scattered long glandular many-celled hairs (rarely with fine downwardly directed sericeous hairs)
Morphology Leaves
Leaves with petiole of stem-leaves (4–)6.5–12 cm long; lamina of stem-leaves ovate-cordiform or broadly so, 10–18 × 7.5–15 cm, upwards smaller and narrower, apex acuminate, base of stem-leaves cordate (rarely subcordate) with sinus (0.2–)0.5–1 cm deep, of upper leaves cuneate to subcordate, margin grossly double-dentate with large triangular teeth 0.5–1 cm long, glabrous or with scattered hairs along veins and near margins, with distinct domatia in angles of main lateral veins beneath
Morphology Reproductive morphology Inflorescences
Inflorescence narrow and racemiform when young, an open panicle later, 7–20 cm long; flowers in 3(–5)-flowered cymes or solitary towards tip of branches; bracts white, soon caducous, clasping young partial inflorescences; branches, bracts and pedicels glandular-tomentose with long manycelled hairs and with a fine “undercoat” of non-glandular hairs; pedicels to 6 mm long
Morphology Reproductive morphology Flowers Calyx
Calyx glandular-pubescent or densely so with broad glossy hairs and with a fine nonglandular “undercoat”, 9–18(–22 in fruit) mm long along dorsal lobe which is ± 2 mm longer than the others; lobes linear, 1–1.5(–2) mm wide
Morphology Reproductive morphology Flowers Corolla
Corolla white to pale mauve with light to dark brown throat and yellow patch on lower lip, throat with dense long white hairs on lower lip and two lateral lobes, sparser or absent on dorsal lobes, 20–24 mm long, cylindric tube 1–2(–4) mm long, throat 9–10 mm long; lobes all transversely elliptic, 6–8 × 7–8 mm; papillate area on lower lip semi-circular or divided into two patches
Morphology Reproductive morphology Flowers Androecium Stamens Filaments
Free part of filaments 2–5 mm long and free fused part ± 1 mm, glabrous or longer with a few hairs; anthers 3–4 mm long, spur 1–1.5 mm long
Morphology Reproductive morphology Flowers Gynoecium Stigma
Stigma 1–2 mm long, dorsal lobe present, minute or absent.
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary densely hairy all over
Morphology Reproductive morphology Fruits
Capsule ± 15 mm long, glandular and hairy all over
Morphology Reproductive morphology Seeds
Seed ± 4 × 3.5 mm
Ecology
Podocarpus forest on ridgetops, bamboo forest; (1200–)2500–3000 m
Note
According to Axel Poulsen (pers. comm.) this species flowered gregariously in 1994 on the Uganda side of the Ruwenzori. I have not seen any authentic material of this species but C.B.Clarke (l.c.), who saw the type, annotated Scott Elliot s.n. (BM, K) as the same species. There are, however, some discrepancies between the material seen for this account and Lindau’s original description. He describes the stems as tomentose and the leaves as being ovate and truncate at base. It is most likely that the specimen collected by Stuhlmann consisted only of the apical part of a stem, and the “tomentose” stem thus refers to the indumentum of the inflorescence axes. The description of the “leaf” as ovate with truncate base would also seem to refer to one of the narrow leaves immediately below the inflorescence.
