Lobostemon is a genus of flowering plants belonging to the family Boraginaceae. Its native range is South Africa. The majority of species are limited to the winter rainfall area of the country, from Springbok to Mossel Bay. In Afrikaans these species are known as agtdaegeneesbos, or loosely translated, bush that will heal in eight days. As this name suggests, many species have medicinal properties. This is best known from Lobostemon fruticosus, which is used for treating wounds, blood poisoning, ringworm, skin diseases and syphilis.

The leaves of Lobostemon glaucophyllus are lanceolate or oblanceolate in shape and possess hairs that are similar in length. The inflorescence is cymous, with a large number of flowers per cyme. The flowers are small (rear petals less than 17 mm long), bell-shaped and fused below to form a corolla tube; the 5 sepals are lanceolate, similar in width; and unfused to each other; the 5 petals are predominantly violet-blue and hairless on the outside. The 5 stamens are shortly fused to the petals above the staminal scales (less than 5 mm); staminal scales occur well below the entrance of the throat of the corolla tube and are well developed and possess lateral lobes. Styles are hairy. Lobostemon glaucophyllus flowers mainly from July to November. It is widespread, occurring from Nieuwoudtville in the north to Franschoek in the south and as far as Gamka Mountain Nature reserve in the east. It frequently occurs on granitic soils towards the southern reaches of its distribution range, but also occurs in the more limey soils of the Sand Plain Fynbos as well as sandstone soils of the Mountain Fynbos vegetation.
