Leucochrysum albicans, commonly known as hoary sunray, [2] is a flowering plant in the family Asteraceae. It is a small perennial with grey leaves, white or yellow flower-heads and is endemic to Australia.
Leucochrysum albicans is an upright, tufted perennial to 45 cm (18 in) high. The leaves are linear to oblong or broadly egg-shaped, woolly, 2–10 cm (0.79–3.94 in) long, 1–9 mm (0.039–0.354 in) wide, light grey and crowded near the base of the stems. The flower heads 2–4 cm (0.79–1.57 in) in diameter, borne singly on a slim peduncle 7–15 cm (2.8–5.9 in) long. The outer bracts brown, inner bracts white or yellow in rows, triangular to narrow-elliptic shaped with a woolly lamina at the base. Flowering occurs in spring and summer and the fruit is an achene 3 mm (0.12 in) long and covered with feathery-like white bristles. [3] [4] [5] [6]
The species was first formally described by botanist Allan Cunningham in 1825 in Geographical Memoirs on New South Wales and gave it the name Helichrysum albicans. [7] In 1992 Paul Graham Wilson changed the name to Leucochrysum albicans in the journal Nuytsia . [8] [9] The specific epithet (albicans) means "whitish". [10]
In the same edition of the journal Nuytsia, Wilson described three varieties and two subspecies, albicans and alpinum of L. albicans. [9] In 2010 Neville Grant Walsh transferred von Mueller's Helipterum incanum var. alpinum to Leucochrysum as L. alpinum in the journal Muelleria , including L. leucochrysum subsp. alpinum as a synonym. [11] In a 2015 edition of Muelleria, Walsh raised the rank of de Candolle's Helipterum incanum var. tricolor to subspecies as L. albicans subsp. tricolor. [12]
The names of the two subspecies have been accepted by the Australian Plant Census:
Hoary sunray is a widespread species found growing in moist, rocky alpine locations in woodlands and grasslands on nutrient poor soils in New South Wales, Victoria, Queensland and Tasmania. [3] [4] [5] [15] Subspecies tricolor mainly grows in grassland or grassy woodland at altitudes between about 100 and 900 m (330 and 2,950 ft) in disjunct populations in Tasmania, Victoria and south-eastern New South Wales, although it has not been recorded this century in Victoria. [17] [18] [19] [20]
Subspecies tricolor is listed as "endangered" under the Australian Government Environment Protection and Biodiversity Conservation Act 1999 , [20] the New South Wales Government Biodiversity Conservation Act 2016 [19] and the Victorian Government Flora and Fauna Guarantee Act 1988 . [18] A National Recovery Plan has been prepared. [21]
