Sub-category: Aster family
Syn. Bidens coronata. An annual herb up to 50 cm tall. Ray florets are yellow with red or purple flecks; disc florets are yellow. The plants are zoochorous; their seeds will stick to clothing, fur or feathers, and be carried to new habitat. This has enabled them to colonize a wide range, including many oceanic islands.
Grows in sandy soil in open woodlands.
