Description
editOlearia stellulata is a shrub that typically grows to a height of up to 2 m (6 ft 7 in), its branchlets densely covered with yellowish, star-shaped hairs. Its leaves are lance-shaped or narrowly elliptic, 30–75 mm (1.2–3.0 in) long and 6–18 mm (0.24–0.71 in) wide with about 5 to 10 teeth on each side. The upper surface of mature leaves is glabrous, the lower surface densely covered with yellowish, star-shaped hairs. The heads or daisy-like "flowers" are arranged in corymbs or panicles on a peduncle 8–20 mm (0.31–0.79 in) and are 15–25 mm (0.59–0.98 in) in diameter with 8 to 15 white ray florets, surrounding 8 to 15 yellow or mauve disc florets, the ligule 6–10 mm (0.24–0.39 in) long. Flowering occurs from November to January and the fruit is a ribbed achene, the pappus with bristles 3–4 mm (0.12–0.16 in) long.[2]
Taxonomy
editThis daisy was first formally described in 1806 by Jacques Labillardière who gave it the name Aster stellulatus in his Novae Hollandiae Plantarum Specimen.[3][4] In 1836, Augustin Pyramus de Candolle changed the name to Olearia stellulata in his Prodromus Systematis Naturalis Regni Vegetabilis.[5] The specific epithet (stellulata) means "small stars".[6]
Distribution and habitat
editOlearia stellulata is found in Victoria and Tasmania. In Victoria it is apparently confined to the Chapple Vale area in the Shire of Colac Otway and in Tasmania it is widespread and common in forests, sometimes intergrading with O. lirata and O. phlogopappa.[2][7]
