Ammobium alatum, commonly known as the winged everlasting,[1] is a species of perennial herb in the daisy family Asteraceae and is both a native and an introduced species in south-eastern Australia. It has prominently winged stems, most of its leaves at the base, and heads of yellow florets surrounding by papery, white involucral bracts.
Description
Ammobium alatum is a species of perennial herb, occasional an annual, that typically grows to a height of Шаблон:Cvt with winged, woolly-hairy, usually much-branched stems. Most of its leaves are at the base of the plant and are narrow egg-shaped to narrow triangular. The basal leaves are Шаблон:Cvt long and Шаблон:Cvt wide on a petiole Шаблон:Cvt long. There are a few sessile, bract-like leaves on the stems. The flowers are Шаблон:Cvt wide with bright yellow florets that become darker with age, the corolla about Шаблон:Cvt long. The florets are surrounded by papery, white involucral bracts Шаблон:Cvt long with jagged edges. Flowering mainly occurs from November to April and the cypselas are linear, wrinkled and dark brown with an awn up to Шаблон:Cvt long.[2][3]
Taxonomy and naming
The genus Ammobium and Ammobium alatum were first described in 1824 Robert Brown in Curtis Botanical Magazine.[4][5] The name Ammobium is from the Greek words, ammos ("sand") and bios (" life"), describing the genus as growing in sand,[5][6] and the specific epithet alatum is from the Latin alatus meaning "winged"[7] in reference to its winged stems.[8]
Distribution and habitat
The winged everlasting often grows in disturbed environments such as on roadsides and agricultural land, and sometimes on riverbanks where the seeds have been carried from disturbed areas. Records of this species in natural habitats are from eucalypt forests in plateau and rocky cliffs in northern New South Wales, from river banks in the upper Snowy River in Victoria, from the Northern Tablelands and North West Slopes of New South Wales and from south-east Queensland.[3] Robert Brown found it "growing plentifully near the shores of Port Hunter (or the Coal River) in New South Wales" in 1804.[5] The species is naturalised in South Australia, The Australian Capital Territory and Tasmania, and in places outside its natural distribution in New South Wales.[9]
