Bur-daisy

Calotis cuneifolia, commonly known as bur-daisy or purple burr-daisy, is an annual to short-lived perennial herb in the daisy family (Asteraceae) native to Australia, particularly the inland regions of New South Wales, Queensland, Victoria, and South Australia. It grows as a small, sparsely branched plant typically 10 to 40 centimeters tall, with slender erect stems arising from a basal rosette. The leaves are wedge-shaped (cuneate) to spathulate, toothed at the apex, gradually narrowing to a sessile or stem-clasping base. Solitary daisy-like flower heads are borne on long peduncles and consist of mauve to purple ray florets surrounding a yellow disc. The fruits are flattened achenes crowned by two stiff, barbed awns derived from the modified pappus, which form a small burr that readily attaches to wool, fur, and clothing for dispersal. It occupies open woodlands, grasslands, and disturbed roadsides on a range of soils.
