[Wikipedia] Leaf & Flower Head Details: Leaves are thread-shaped and terete (round in cross-section, very gradually tapering; the epithet teretifolia means "with terete leaves"). One plant can produce many small yellow flower heads each with 5-7 disc florets but no ray florets. (link added by Mary Ann Machi)
