About Prostanthera linearis R.Br.
Prostanthera linearis, commonly known as narrow-leaved mint-bush, is an erect, faintly aromatic shrub that usually grows 1 to 3 meters (3 feet 3 inches to 9 feet 10 inches) tall. Its leaves are hairless, ranging from narrowly egg-shaped to linear, and measure 15 to 45 millimeters (0.59 to 1.77 inches) long and 2 to 3 millimeters (0.079 to 0.118 inches) wide. Each leaf grows on a stalk (petiole) that is less than 2 millimeters (0.079 inches) long. The flowers grow in the axils of leaves near the ends of branchlets, with 2 to 3 millimeter (0.079 to 0.118 inch) long bracteoles at their base. The sepals are 5.5 to 6 millimeters (0.22 to 0.24 inches) long, forming a tube 2 to 3 millimeters (0.079 to 0.118 inches) long with two lobes; the upper lobe is 2.5 to 3 millimeters (0.098 to 0.118 inches) long. The petals are 8 to 12 millimeters (0.31 to 0.47 inches) long, white, and often tinged with pinkish-mauve. This species grows in eucalyptus forest, frequently near streams, in sandy or gravelly clay soils. It is found in Queensland, Australia, and along the New South Wales coast from Sydney south to Milton.
