Medicosma glandulosa is a species of shrub or small tree in the family Rutaceae and is endemic to far north Queensland. It has elliptical to egg-shaped leaves and flowers that are white with red tips or cream-coloured, borne singly or in small groups in leaf axils.

Description
Medicosma glandulosa is a tree that typically grows to a height of 10 mm. The leaves are arranged in opposite pairs or in whorls of three or four and are elliptical to narrow egg-shaped with the narrower end towards the base, 23–120 mm long and 10–40 mm wide on a petiole 3–10 mm long. The flowers are arranged singly or in small groups up to 7 mm long and are sessile or on a pedicel up to 1.5 mm long. The sepals are 1.5–2 mm long and glabrous and the petals are white with red tips or cream-coloured, 2.5–3.5 mm long and glabrous apart from a few hairs on the tip of the lower surface. Flowering occurs in most months and the fruit is a follicle 4–5 mm long.
