Ptilotus decipiens, commonly known as false mulla mulla,[2] is a species of flowering plant in the family Amaranthaceae and is endemic to inland areas of Australia. It is a dense annual plant or short-lived perennial herb with hairy, elliptic to four-sided or egg-shaped stem leaves, and short, densely packed spikes of whitish flowers.
Description
[edit]Ptilotus decipiens is a dense, annual or short-lived perennial herb with many stems, that typically grows to a height of 20 cm (7.9 in) and has stems and leaves that become glabrous with age. The stem leaves are elliptic, four-sided or egg-shaped, 8–35 mm (0.31–1.38 in) long and 5–19 mm (0.20–0.75 in) long, and there are no leaves at the base of the plant. The flower spikes are short, egg-shaped or cylindrical, up to about 25 mm (0.98 in) long and 5–12 mm (0.20–0.47 in) wide and densely packed with whitish flowers with colourless bracts and bracteoles with a prominent midrib. The outer tepals are 3.4–4.5 mm (0.13–0.18 in) longer and the inner tepals 2.5–3.6 mm (0.098–0.142 in) long and there are five fertile stamens.[3][4]
Taxonomy
[edit]This species was first formally described in 1870 by George Bentham who gave it the name Alternanthera decipiens in his Flora Australiensis from specimens collected in Queensland.[5] In 1934, Charles Gardner changed the name Ptilotus decipiens in Enumeratio plantarum Australiae occidentalis.[1] The specific epithet (decipiens) means 'deceiving',[6] alluding to the plant's not looking like other species of "Ptilotus".[2]
Distribution and habitat
[edit]Ptilotus decipiens grows on rocky or gravelly hills[3] in the Central Ranges, Great Sandy Desert, Pilbara and Tanami bioregions of Western Australia,[4] the southern half of the Northern Territory[3] in South Australia[2] and in Queensland.[1]
Conservation status
[edit]Ptilotus decipiens is listed as of "least concern" by the Queensland Government Nature Conservation Act 1992.[7]
