Ammobium alatum
Ammobium alatum, commonly known as the winged everlasting, 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 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 long and wide on a petiole long. There are a few sessile, bract-like leaves on the stems. The flowers are wide with bright yellow florets that become darker with age, the corolla about long. The florets are surrounded by papery, white involucral bracts 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 long. Taxonomy and naming. The genus "Ammobium" and "Ammobium alatum" were first described in 1824 Robert Brown in "Curtis Botanical Magazine". The name "Ammobium  is from the Greek words, ammos" ("sand") and "bios" (" life"), describing the genus as growing in sand, and the specific epithet "alatum" is from the Latin "alatus" meaning "winged" in reference to its winged stems. 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. Robert Brown found it "growing plentifully near the shores of Port Hunter (or the Coal River) in New South Wales" in 1804. The species is naturalised in South Australia, The Australian Capital Territory and Tasmania, and in places outside its natural distribution in New South Wales.
