Berkheya macrocephala flowerheads

The yellow flowerheads of Berkheya macrocephala grow on erect, sparsely leaved peduncles. They are large, about 10 cm in diameter. The specific name, macrocephala, is derived from the Greek words kephale meaning head and makros meaning long, later on the word meaning includes large, borrowed widely into other languages. It refers to the large flowerheads.

The long, narrow ray florets taper at both tip and base, spreading around a many-flowered disc. The involucre comprises 8 mm broad bracts, its margins and tips spiny. Flowering happens from before midspring to after midsummer (Pooley, 1998; iNaturalist; https://www.worldfloraonline.org).
