Angianthus preissianus, commonly known as common cup-flower, salt angianthus[2] or salt cup-flower,[3] is a species of flowering plant in the family Asteraceae, and is endemic to southern Australia. It is a prostrate to erect annual herb with narrowly elliptic leaves, compound heads of 5 to 100 yellow flowers, and egg-shaped achenes without a pappus.
Angianthus preissianus is a prostrate to erect annual herb that typically grows to a height of 1–8 cm (0.39–3.15 in), usually with several stems from the base, sometimes glabrous or hairy. The leaves are narrowly elliptic to more or less linear, sometimes succulent, 5–12 mm (0.20–0.47 in) long and 1–2 mm (0.039–0.079 in) wide. The flowers are yellow and borne in compound heads of 5 to 100 pseudanthia, the heads 4–10 mm (0.16–0.39 in) long and 4–11 mm (0.16–0.43 in) wide. There are conspicuous involucral bracts at the base of the compound heads, and one or two bracts 1.6–2.3 mm (0.063–0.091 in) long at the base of the pseudanthia. Flowering occurs from September to January, and the achenes are egg-shaped, 0.5–0.8 mm (0.020–0.031 in) long and about 0.3 mm (0.012 in) in diameter without a pappus.[2][3][4][5][6]
