In Cameroon it is found in the Mount Kupe and the Bamenda Highlands. Its natural habitats are forested valley slopes in submontane forests at elevations of 950 to 1,600 m. It is threatened by habitat loss due to logging and clearance for agricultural land.

The species was first described as Acioa johnstonei by Arthur Clague Hoyle in 1932. In 1979 Ghillean Prance and Frank White placed the species in genus Dactyladenia as D. johnstonei.
