Morphology Reproductive morphology Inflorescences
Cymes 1–3(–several)-flowered, pubescent; peduncle 2.4–4.5 cm long; pedicels c. 0.5 cm long; bracts c. 2–3 mm long, linear
Morphology Reproductive morphology Flowers Calyx

Morphology Reproductive morphology Flowers Corolla
Corolla white or pale pink, sometimes with darker centre, 8–12(–20) mm long

Note
This is a very variable species that has been subdivided in various ways into infraspecific taxa (see Verdc. in Kew Bull. 12: 344–346, 1957). The Somali material may perhaps be placed in var . aschersonii (Engl.) Verdc., but var. abyssinicus (Hall. f.) Rendle is an older name for this, as d in Cuf., Enum.: 739 (1961).
