Description
editMentha diemenica is a small, prostrate, perennial herb with underground spreading stems and leafy, erect, ascending branches to 15 cm (5.9 in) high. The branches are covered with occasional to thickly recurved hairs. The leaves are arranged in opposite pairs, aromatic, mostly oval-shaped, 6–20 mm (0.24–0.79 in) long, 4–12 mm (0.16–0.47 in) wide, lower surface has short, upright, scattered hairs, margins entire or sparsely toothed, apex rounded or almost pointed and the petiole 0–3 mm (0.00–0.12 in) long. The purple or rarely white flowers are usually borne in clusters of 3-8 at the end of branches in the leaf axil, lobes pointed or widely pointed, outer surface thickly covered with short hairs and long hairs on the margin. The corolla is 4–7 mm (0.16–0.28 in) long with four petals extending 2–3 mm (0.079–0.118 in) beyond the ribbed calyx tube that is covered in spreading hairs. Flowering occurs from late spring to summer and the fruit is a mericarp, obovoid-shaped, dry, segmented and about 1 mm (0.039 in) long.[3][4]
