The She Oak

I have walked past this group of trees a hundred times or more and although I have stopped to look at their impressive size it never occurred to me to take a closer look. This is Casaurina equisitifolia or the ironwood tree (she oak, beach oak, beach she-oak, whistling tree, horsetail she oak, horsetail beefwood, horsetail tree, Australian pine, ironwood, whistling pine to name but a few).
Several thousand miles from its native land, it must have been planted by a mariner or perhaps somebody from one of the consulates that existed here on Symi a hundred or so years ago.
