Otostegia integrifolia, more commonly known as Abyssinian rose, a plant belonging to the family Lamiaceae, is endemic to Ethiopia, in the dry evergreen woodlands of the Tigray, Gondar, Wollo and Gojjam regions, North Shewa, Kaffa and Hararghe regions, as well as in the dry and moist agroclimatic zones of the district known as Dega, at altitudes of 1,300—2,800 m. above sea-level.It also grows in Yemen, northwest of Mukalla. In Ethiopia, O. integrifolia is commonly known by its Amharic vernacular of tinjute = ጥንጁት (alt. sp. Tindjut). Since this plant is endemic, those local scientists can clearly answer your question.

Otostegia integrifolia now synonym with Rydingia integrifolia (Benth.) Scheen & V.A.Albert.
