Phaseolaster elliptica, commonly known as the sticky daisy bush,[2] is a shrub in the family Asteraceae and is native to New South Wales and Queensland in eastern Australia. It has scattered, sticky leaves and white flowers in summer and autumn.
Description
[edit]Phaseolaster elliptica is a shrub that typically grows to a height of 2 m (6 ft 7 in) and has scattered, curved, elliptic leaves 20–115 mm (0.79–4.53 in) long, 5–38 mm (0.20–1.50 in) wide on a petiole up to 12 mm (0.47 in) long. The upper surface of the leaves is sticky and the lower surface is a paler green. The heads or daisy-like "flowers" are arranged in loose groups on the ends of branches on a peduncle up to 12 mm (0.47 in) long and are 11–26 mm (0.43–1.02 in) wide. Each head has 8 to 23 white ray florets surrounding 8 to 30 yellow disc florets. Flowering occurs between November and May and the fruit are bristly achenes.[2]
Taxonomy and naming
[edit]The species was first formally described as Olearia elliptica by Augustin Pyramus de Candolle in 1836, who published the description in his 17-volume treatise, Prodromus Systematis Naturalis Regni Vegetabilis.[3][4] The specific epithet (elliptica) is a Latin word meaning "a defective circle" or "an ellipse".[5]
In 1993, Peter Shaw Green described two subspecies of O. elliptica that were accepted by the Australian Plant Census: O. elliptica subsp. elliptica in eastern Australia and O. elliptica subsp. praetermissa, which is endemic to Lord Howe Island.[6] In 2020 Guy L. Nesom placed the species in the newly-described genus Phaseolaster as P. elliptica after Olearia had been found to be polyphyletic, and raised subsp. praetermissa to a full species as P. praetermissa.[7]
Distribution and habitat
[edit]The species occurs from Berry northwards along central and eastern New South Wales to the Queensland border.[2] It is found in areas of annual rainfall of over 900 mm in the Sydney Basin.[8]
Use in horticulture
[edit]Sticky daisy bush adapts readily to cultivation, preferring acidic soils in part shade or sun.[9]
