Type
Type: Congo-Kinshasa, W slope of Ruwenzori Mts, Butahu Valley, Stuhlmann 2301 (B†, holo.)
Morphology General Habit
Coarse often strongly aromatic shrubby perennial herb or shrub to 5 m tall, erect (rarely scandent); stems glabrous to densely puberulous (rarely velutinous)
Morphology Leaves
Leaves sometimes purplish tinged; petiole up to 17 cm long, upper often subsessile; lamina ovate to cordiform or broadly so, largest 14–43 × 11–32 cm, apex drawn out into an acuminate to cuspidate tip, base cuneate to cordate, margin grossly and irregularly dentate with larger and smaller teeth, the larger teeth up to 2 cm long and often toothed again, glabrous to densely puberulous along veins, glabrous or subglabrous on lamina
Morphology Reproductive morphology Inflorescences
Panicle ± contracted to rather open, purplish, 10–40 cm long, puberulous to pubescent, without capitate glands; primary bracts green or purple, ovate-elliptic or broadly so, from leaf-size down to 6 × 3 mm near apex, entire or lower toothed, puberulous or sparsely so along veins, no glands; secondary bracts elliptic, 2–20 × 1–7 mm; pedicels 1–9(–12) mm long, puberulous
Morphology Reproductive morphology Flowers Calyx
Calyx purplish, puberulous or densely so and with scattered to dense short-stalked capitate glands (rarely without), sometimes also with long pilose hairs; ventral and lateral lobes linear-lanceolate, 9–20 mm long, tapering gradually or slightly spathulate, dorsal narrowly oblong, 10–22 mm long, 2–4 times wider and slightly longer than the rest
Morphology Reproductive morphology Flowers Corolla
Corolla pale blue to brilliant royal blue, mauve to violet or purple, upper lip usually paler and often with dark streaks, 25–52 mm long, with purplish glandular hairs all over; tube 5–12 mm long; lower lip 17–40 mm long, lobes ovate, 4–13 mm long. Filaments, style and stigma white to mauve; anthers grey to black, 4–9 mm long, glabrous or hairy; staminodes up to 1 cm long, filiform, puberulous
Morphology Reproductive morphology Fruits
Capsule 25–45 mm long, the valves 3–5 mm wide, glandular-puberulous or densely so, ± scattered non-glandular hairs
Morphology Reproductive morphology Seeds
Seed 3–4 mm long
Figures
Fig 25, p160
Ecology
Wet montane evergreen forest, bamboo forest, usually in wet places along streams, forest edges and clearings; 1200–2600 m
Note
There are several reports of mass-flowering of this species, but even in years where most plants do not flower occasional flowering plants can usually be found. Sidwell (l.c.) uses B. kirungae as the valid name for this species and treats B. cicatricosa as an insufficiently known species because the description of the calyx indumentum (subglabrous) doesn’t fit with the material seen by her. But among the East Congo (Kivu) material at BR there are several collections with a rather sparsely hairy calyx. No plant fitting the original description of B. cicatricosa has been recollected near the type locality. Mildbraed presumably saw the type in Berlin prior to describing var. kivuensis, but the possibility that the two taxa are not the same species clearly exists. Points in favour of them being conspecific are the short calyx and hairy – but not glandular – capsule.
