- Casuarina equisetifolia is a deciduous tree that occurs in open, coastal habitats including sand beaches, rocky coasts and sand dunes. Trees can grow to over 100 ft. (30.5 m) in height.
- The reddish-brown to gray bark is brittle and peels. Branchlets resemble pine needles and are very thin, 4-8 in. (10-20 cm) long and gray-green.
- Male and female flowers are present on the same plant and are inconspicuous. Male flowers occur in terminal spikes, while the female flowers are in small, axillary clusters.
- Fruit are tiny, winged nutlets that each contain one seed. The fruits are contained in woody, cone-like structures that are 0.75 in. (2 cm) long.
- Ecological Threat
- Casuarina equisetifolia is native to Australia and southeast Asia and was introduced into Florida in the late 1800’s.
