Figure 7. Casuarina equisetifolia female flowers, cones and nodes. Cones collected from trees in Florida that have typical traits are often larger than shown in the diagram and are blockier in shape. Note the four visible teeth, their color and size, and the overall hairiness of the needle especially at the edges of the teeth. The diagrams are from Wilson and Johnson (1989) and the pictures are of needles and cones collected in Florida.
