The alternate leaves of Amellus asteroides are spathulate (spoon-shaped) to narrowly obovate (paddle-shaped). The leaves are sessile, i.e. without stalks. They have a dense covering of silky grey hairs on both surfaces, contributing to the dull grey-green leaf colour. The slightly recessed leaf midrib is visible on the upper surface. Leaf margins are entire (Manning, 2007; iSpot).
