An African species with an erect habit and densely hairy. First described by Choisy as Argyreia abyssinica and sometimes apparently recorded as Convolvulus echioides Hochst. ex Choisy, both names now considered synonyms. Choisy described the species from Ethiopia and Roberty (1952) succinctly recorded it “from Eastern Tropical Africa” (Afrique tropicale orientale), although it is not mentioned by Verdcourt (1963) in the Flora of Tropical East Africa. The specimens recorded in our database, i.e. the two isotypes and another collection possibly also studied by Choisy, are all from northern Ethiopia. GBIF also lists records from Cameroon, Chad and Senegal that need to be confirmed.

DESCRIPTION (from: Baker and Rendle, 1905): Stems stout, woody, hollow, erect, nearly 2 ft. long and 2 lin. thick at the base, densely hairy. Leaves ovate or the lower smaller ones more or less oblong, ascending, entire, acute or the lower obtuse, 1 1/4–3 in. long, 3/4–1 1/2 in. broad, greenish and hairy above, whitish and more densely hairy beneath; petiole very short. Flowers in dense heads from the axils of the upper leaves on ascending peduncles, 1–2 in. long, mixed with persistent lanceolate very hairy foliaceous bracts, reaching 1 1/4 in. long. Sepals ovate-lanceolate to lanceolate, apex acuminate, the outermost nearly 8 lin. long by 2 1/2 lin. broad, the innermost 6 lin. long by 1 1/2 lin. broad, densely covered on the back with long yellowish hairs. Corolla campanulate-funnel-shaped, 1–1 1/3 in. long, and about as broad, tube and throat deep red-purple, limb yellow, silky outside. Fruit and seeds not seen.
