Morphology Reproductive morphology Flowers Corolla
Corolla 4–11 mm long, blue
Morphology Reproductive morphology Flowers Androecium Stamens Anthers
Tube 0.8–2 mm long, shortly pubescent on the back or rarely glabrous; 2 lower anthers each with a tuft of hairs and a hyaline appendage at the apex
Morphology Reproductive morphology Fruits
Capsule with inferior part 2.4–6 mm long and valves 0.6–1.2 mm long

Note
The collections from Somalia are fairly large-flowered and belong to subsp. fervens which also occurs in Ethiopia, Kenya, Tanzania, Zimbabwe, Mozambique, Comoro Is., Madagascar and Réunion. Subsp. recurvata (E. Wimm.) Thulin, with calyx-lobes recurved in fruit, is known from Uganda, Kenya, Tanzania, Dem. Rep. Congo, Burundi, Zambia, Zimbabwe, Mozambique and Angola.
