Figure 6. Casuarina cunninghamiana cones and male flowers. The cones (top left) are from a tree in Ruskin and are similar in size and shape to those shown in the diagram (Wilson and Johnson, 1989). The seeds are smaller than those collected from C. equisetifolia. The young developing cones (above, left) were produced on an old tree in Ruskin; the male flowers (above, right) were produced on a tree in Fort Pierce in late February, 2008.
