Leaves are narrow with serrated edges, pointed tips, and covered with hairs that produce a sticky and aromatic resin. Composite flower heads are made up of yellow disk florets, surrounded by a ring of ray florets, held by a green, cylindrical involucre. Seeds from a wind-dispersed puff ball.
River valleys and damp roadsides, including Ajloun, Jerash, Amman, Salt, and Karak.
