Hypericum annulatum subsp. intermedium (Nomenclature)
Stems without or rarely with few black glands, sparsely puberulous to glabrous. Leaves without laminar black glands, sparsely and very shortly pubescent to puberulous or glabrous. Sepals short- to long-glandular-ciliate (i.e. cilia shorter to 2 or more times as long as glands), occasionally with some laminar glands black. Petals with few (rarely more numerous) punctiform laminar black glands, rarely red-veined in bud.
Saudi Arabia (Asir), Sudan Republic (S. Red Sea Hills), N. Ethiopia (Eritraea to L. Tana and N. Shoa).
Subsp. intermedium varies north-eastward by decreasing pubescence and increasing glandularity, so that the Sudanese and Arabian plants are glabrous with black-gland-dotted sepals and stems. The Arabian plants also have sepals with short glandular cilia, whereas in the others they are medium to long. The eastern Ethiopian population has more in common with the East African plants and has therefore been included in subsp. afromontanum.
