can reach up to 4 metres <strong>in</strong> height. The roots<br />

<strong>of</strong> this species occasionally knot above <strong>the</strong> soil<br />

around mudflats and <strong>in</strong> coastal mangrove<br />

communities (Wightman 1983).<br />

The species name 'ovalis' refers to <strong>the</strong> oval shape <strong>of</strong> <strong>the</strong> leaves. The leaves generally<br />

range between 3 and 7 cm <strong>in</strong> length. If plucked from <strong>the</strong> stem Excoecaria leave stems<br />

will release a small amount <strong>of</strong> milky white fluid called latex. The flowers <strong>of</strong><br />

Excoecaria occur between October and December. The <strong>in</strong>dividual flowers <strong>of</strong> this<br />

species are t<strong>in</strong>y, <strong>the</strong> <strong>in</strong>florescence produced are <strong>in</strong> <strong>the</strong> form <strong>of</strong> spikes up to 3 cm long.<br />

Small mottled brown seeds occur between December and February (Wightman 1983).<br />

While <strong>the</strong> latex <strong>of</strong> Excoecaria is considered to<br />

be toxic and is thought to cause irritation to<br />

eyes (hence <strong>the</strong> common name), it can be used<br />

medic<strong>in</strong>ally <strong>in</strong> <strong>the</strong> treatment <strong>of</strong> some diseases<br />

<strong>in</strong>clud<strong>in</strong>g leprosy and for mar<strong>in</strong>e st<strong>in</strong>gs. The<br />
