Trinity Beach, north end.
One tree. Terminalia muelleri is common here on the rocky coast. T. arenicola is absent here but common on sand on the edge of the beach all along this coast. I have now encountered four of these hybrid trees in different places on this coast.
The last photo shows T. arenicola [left], T. arenicola x muelleri [mid] and T. muelleri [right].
Shrub .5 to 2 meters tall. Male and female flowers on separate spikes on same plant.
