Type
Type not indicated
Morphology General Habit
Perennial (rarely shrubby) herb with well-developed rootstock, often mat-forming; stems procumbent or trailing, rooting or not (rarely erect in pyrophytic forms), up to 80 cm long, subglabrous to densely whitish pubescent, often densest (or only) in a broad band
Morphology Leaves
Leaves obovate (more rarely elliptic or broadly so), largest 1.2–5(–6) × 0.6–2(–2.8) cm, apex broadly rounded to retuse with a small triangular tip, on both sides glabrous to sparsely pubescent with ± curled hairs, often only along midrib and veins with glabrous lamina (more rarely uniformly pubescent or densely so), margin distinctly crisped-ciliate (rarely not)
Morphology Reproductive morphology Flowers
Flowers in condensed axillary cymes with 1–3 flowers, not condensed towards tip of stems; peduncle 3(–12) mm long, branches up to 1 mm long, puberulous; outer bracts up to 1.2 cm long; inner bracts and bracteoles linear, up to 7 mm long, often with glands
Morphology Reproductive morphology Flowers Calyx
Calyx 8–12(–18 in fruit) mm long, glabrous to puberulous, often with glabrous tube or only hairy on veins; teeth distinctly ciliate (rarely not), 5–10 mm long, longer than tube or same length
Morphology Reproductive morphology Flowers Corolla
Corolla with almost symmetrical limb (tube sometimes slightly curved), white, pale blue to blue or mauve to violet, tube usually paler, puberulent, 10–19 mm long of which the linear tube 4–8 mm, the throat 3–7 mm and the limb (2–)3–5 mm; lobes oblong, erect or recurved in lower lip
Morphology Reproductive morphology Flowers Androecium Stamens
One pair of stamens sometimes reduced to staminodes (see fig 141 in Fl Rwanda 3: 454 (1985)); free part of filaments 2–4 mm long, with scattered hairs throughout or glabrous upwards; anthers 1–2 mm long, muticous or with minute spurs
Morphology Reproductive morphology Fruits
Capsule (8–)10–14 mm long, shorter than calyx (rarely same length)
Morphology Reproductive morphology Seeds
Seed 2–3 mm long
Figures
Fig 28: 1-10, p185
Ecology
Montane bushland and grassland, Acacia and Combretum wooded grassland and bushland, grassland on black cotton soil (sometimes fireswept), secondary grassland and bushland, eroded areas, roadsides, old cultivations; (900–)1100–2500 m
Note
Usually easily distinguished from D. multicaulis and D. nagchana by its obovate leaves and larger flowers. But in areas where the three meet in man-made secondary habitats intermediate forms occur. See also notes after the preceeding species.
