Caption: Spinningtop conebush seed. Close-up of a seed (left) from a spinningtop conebush (Leucadendron rubrum) seed head (right). The seed (black) is suspended from a parachute of fine hairs called a pappus. The hairs help the seed to catch the wind when released from the seed head. The seeds can be dispersed many kilometres on the wind. Conebushes are indigenous to South Africa. Plants may be either male or female. The male plant has small narrow flowerheads, while the female plant (pictured) has large green cone-shaped flower heads, that later change to a copper colour.
