Leptospermum emarginatum

Leptospermum emarginatum is a shrub that typically grows to a height of 1.5–4 m (4 ft 11 in–13 ft 1 in). It has rough bark that is shed in stringy strips on the larger branches and smooth bark on the younger stems. The leaves are aromatic, narrow egg-shaped to lance-shaped with the narrower end towards the base, mostly 20–30 mm (0.79–1.18 in) long and 2.5–7 mm (0.098–0.276 in) wide with a small notch at the tip. The flowers are borne in groups of up to five on short side shoots, each flower 7–9 mm (0.28–0.35 in) in diameter. The floral cup is dark-coloured, glabrous, 2–3 mm (0.079–0.118 in) long, tapering to a pedicel 3–4 mm (0.12–0.16 in) long. The sepals are triangular, 1–1.5 mm (0.039–0.059 in) long, the petals white, 3–4 mm (0.12–0.16 in) long and the stamens 2.5–4 mm (0.098–0.157 in) long in groups of about five. Flowering occurs from November to January and the fruit is a woody, hemispherical capsule 3.5–5 mm (0.14–0.20 in) wide that falls off the plant after the seeds are released.[2][3][4]

Leptospermum emarginatum was first formally described in 1822 by Johann Heinrich Friedrich Link from an unpublished description by Heinrich Wendland and the description was published in Link's book Enumeratio plantarum Horti regii botanici berolinensis altera.[5][6] The specific epithet (emarginatum) is from Latin meaning "notched".[7]

The twin-flower tea-tree grows along river banks and rocky creeks in coastal areas south from the Grose River in New South Wales to near Heyfield in Victoria.[2][3]
