Description

Olearia canescens is a shrub that typically grows to a height of up to 2 m (6 ft 7 in). It has scattered elliptic or egg-shaped leaves, 10–60 mm (0.39–2.36 in) long, 3–21 mm (0.12–0.83 in) wide and more or less sessile. Both surfaces of the leaves are covered with a layer of greyish, felt-like hairs. The heads or daisy-like "flowers" are arranged on the ends of branchlets and are 12–19 mm (0.47–0.75 in) in diameter on a peduncle up to 31 mm (1.2 in) long. Each head has eight to fifteen white ray florets surrounding seven to sixteen yellow disc florets. Flowering occurs from February to August and the fruit is a silky-hairy achene, the pappus with 35–43 long bristles in two rows with an outer row of shorter bristles. [2] [3]

Taxonomy

This daisy bush was first formally described in 1867 by George Bentham who gave it the name Olearia stellulata var. canescens in Flora Australiensis . [4] [5] In 1917 John Hutchinson raised the variety to species status as O. canescens. [6]

In 2014, Andre Messina described two subspecies in Australian Systematic Botany , and the names are accepted by the Australian Plant Census:

Distribution and habitat

Olearia canescens grows in woodland, forest and rainforest in south-eastern Queensland and as far south as the Apsley River and west to the Nandewar Range in New South Wales. [2] [3]
