Medicosma elliptica is a shrub or tree that typically grows to a height of 7 mm (0.28 in) with glabrous branchlets.

The flowers are arranged singly or in small groups in leaf axils and are sessile or on a pedicel up to 1 mm (0.039 in) long.

The petals are white, 4.5–5.5 mm (0.18–0.22 in) long, densely covered with flattened hairs on the back, and remain on the fruit.

[2][3][4] Medicosma elliptica was first formally described in 1985 by Thomas Gordon Hartley in the Australian Journal of Botany from specimens collected in the Bulburin State Forest in 1978.

[5][6] Bulburin medicosma grows in mountainous terrain on steep, rocky hillsides in vine forest with hoop pine (Araucaria cunninghamii), brush box (Lophostemon confertus) and Moreton Bay fig (Ficus macrophylla), in an area previously logged for hoop pine.
