Morphology General Habit
Subshrub up to 10–30 cm tall, usually much branched from the base with ascending stems

Ecology
Altitude range 50–1650 m.

Geed riyood (Somali).
Note
For intermediates between B. argentea and B. hochstetteri in southern Somalia, see under the latter. Characterized by being low-grown and branched from the base, often forming a rosette of stems with dark, narrow leaves, and usually having young stems with silvery tinge from dense, appressed hairs. B. argentea is closely related to B. parviflora R. Br. ex T. Anders. with type from Ethiopia, which is taller and has larger, cordate/truncate, green leaves. The two taxa may ultimately prove to be conspecific and if so, the name B. parviflora would have priority.
