context_page_description: Prostanthera howelliae is a flowering plant in the mint family Lamiaceae and is endemic to New South Wales and Queensland. It is a small shrub with narrow stems, aromatic, hairy leaves and violet-coloured, tube-shaped flowers.
context_section_description: Prostanthera howelliae is an erect or spreading, virgate shrub which grows to a height and spread of 0.3–1.5 m (1–5 ft) with its branches densely covered with short hairs. The leaves have a fragrant odour when crushed, and are narrow egg-shaped, 2.5–10 mm (0.1–0.4 in) long, 0.5–1.5 mm (0.02–0.06 in) wide with their edges turned under. The leaves have a very short stalk, sometimes a maroon tinge and are covered with short, cone-shaped hairs.
  
  The flowers are arranged singly in leaf axils with two bracteoles at  their base, the bracteoles leaf-like, linear in shape, about 1.5 mm (0.06 in) long and remaining on the plant after flowering. The tube formed by the sepals is 4–5 mm (0.16–0.20 in) long, with the tubular part about 2 mm (0.08 in) long. The petal tube is 8–10 mm (0.3–0.4 in) long, pink to purple-mauve and spotted inside the tube. As with many other prostantheras, the petal tube has two "lips" with the upper one having two lobes and the lower one three lobes. Flowering occurs in spring.
