Eremophila debilis, commonly known as winter apple or amulla, is a flowering plant in the figwort family, Scrophulariaceae and is endemic to an area extending from north Queensland to near the border between New South Wales and Victoria in Australia. It is a prostrate shrub with lance-shaped leaves and white, rarely deep mauve flowers.
Eremophila debilis is a prostrate shrub with spreading stems up to 1 m (3 ft) long. It has glossy green, elliptic to lance-shaped leaves which are mostly 32–85 mm (1–3 in) long, 8–20 mm (0.3–0.8 in) wide and glabrous usually with 3 or 4 pairs of prominent teeth on the edges.
The flowers are borne singly or in groups of up to 3 in leaf axils on a stalk 3.5–7.5 mm (0.1–0.3 in) long. There are 5 green, lance-shaped, slightly overlapping sepals mostly 7–10 mm (0.3–0.4 in) long. The petals are 8.5–11 mm (0.3–0.4 in) long and joined at their lower end to form a tube. The petal tube is white to pale mauve and, unlike many others in the genus, does not have spots. The petal tube and lobes are mostly glabrous on the outside but the inside of the tube is filled with soft hairs. The 4 stamens are fully enclosed within the tube. Flowering mainly occurs in spring and summer and is followed by rounded, fleshy, white to reddish purple fruits, which are 7–10 mm (0.3–0.4 in) in diameter.
The species was first formally described by Henry Charles Andrews in 1802 who gave it the name Pogonia debilis. The description was published in The Botanist's Repository for New, and Rare Plants.Robert Brown changed the name to Myoporum debile in 1810 and in 1992 Robert Chinnock changed the name to Eremophila debilis. The specific epithet (debilis) is a Latin word meaning "weak" referring to the decumbent stems of this species.
