Erodiophyllum elderi, commonly known as Koonamore daisy,[2] is a flowering plant in the family Asteraceae and is endemic to Australia. It is a small perennial herb with upright stems and purple daisy-like flowers.
Description
Erodiophyllum elderi is a small, perennial, woody herb with upright, roughly hairy stems to 15–50 cm (5.9–19.7 in) high and 60 cm (24 in) wide. Leaves are bright green, hairy, spear-shaped, 4–10 cm (1.6–3.9 in) long, 2–3 cm (0.79–1.18 in) wide, broadly toothed and tapering to the petiole. The flower heads 5–7 cm (2.0–2.8 in) in diameter, purple or white, disc florets yellow, peduncles hairy, thick, 5–14 cm (2.0–5.5 in) long, bracts lance-shaped, about 1.5 cm (0.59 in) long, hairy, becoming woody and hard as they age. Flowering occurs from winter to early summer and the fruit is a woody achene about 3 mm (0.12 in) long.[2][3]
