Epacris obtusifolia

Epacris obtusifolia, commonly known as blunt-leaf heath,[2] is a species of flowering plant from the heath family, Ericaceae, and is endemic to eastern Australia. It is an erect shrub with few stems, crowded, oblong to elliptic leaves and tube-shaped white or cream-coloured flowers arranged along the stems.

Epacris obtusifolia is an erect shrub, usually with few stems, that typically grows to a height of 0.5–1.5 m (1 ft 8 in – 4 ft 11 in) and has softly-hairy branchlets. The leaves are oblong to elliptic, 3.5–11 mm (0.14–0.43 in) long and 1.0–3.1 mm (0.039–0.122 in) wide on a petiole 0.5–2 mm (0.020–0.079 in) long, the base wedge-shaped and the tip blunt. The flowers are arranged along up to 150 mm (5.9 in) of the stems, on a peduncle up to 1.5 mm (0.059 in) long. The sepals are 3.9–7 mm (0.15–0.28 in) long, the petals white or cream-coloured, and joined at the base to form a cylindrical or bell-shaped tube 4.8–14.2 mm (0.19–0.56 in) long with lobes 1.6–4 mm (0.063–0.157 in) long. Flowering occurs throughout the year with a peak from July to January.[2][3][4][5]

Taxonomy

Epacris obtusifolia was first formally described in 1804 by James Edward Smith in his Exotic Botany.[6][7] The specific epithet (obtusifolia) means "blunt-leaved".[8]
