Marianthus bicolor, commonly known as painted marianthus,[2] is a species of flowering plant in the family Pittosporaceae and is endemic to the southwest of Western Australia. It is a low, erect, spreading shrub or climber with narrowly elliptic leaves and white to cream-coloured flowers with maroon or purple striations flowers arranged in branched clusters.
Description
[edit]Marianthus bicolor is a low, erect, spreading shrub or climber with reddish purple new stems. Its adult leaves are narrowly elliptic, 26–45 mm (1.0–1.8 in) long and 5–12 mm (0.20–0.47 in) wide on a short petiole. The leaves are thick and both surfaces of the mature leaves are covered with a waxy bloom. The flowers are borne in branched clusters on a peduncle 15–20 mm (0.59–0.79 in) long, the sepals egg-shaped, thickened and wavy, up to 1.5 mm (0.059 in) long and yellow on the outer surface. The five petals are narrowly spatula-shaped, 10–14 mm (0.39–0.55 in) long and up to 3.5 mm (0.14 in) wide, white to cream-coloured with maroon or purple striations. Flowering mainly occurs from December to March.[2][3]
Taxonomy
[edit]This species was first formally described in 1839 by Alois (Aloys) Putterlick in Novarum Stirpium Decades.[4][5] In 1860, Ferdinand von Mueller transferred the species to Marianthus as M. bicolor in his Fragmenta Phytographiae Australiae.[6] The specific epithet (bicolor) means "two colours".[7]
Distribution and habitat
[edit]Marianthus bicolor grows in mallee in valleys, on hills, flats, sandplains and roadsides, and is widespread in the south-west of Western Australia, mainly from the Darling Range to Ravensthorpe.[2][3]
Conservation status
[edit]Marianthus bicolor is listed as "not threatened" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions.[2]
