The gum trees (eucalypts) on our property are many! And often hard to identify as my only book that covers trees has no photos and some minimal descriptions of leaves. This is, I believe, a ghost gum. Its white trunk and branches are so vivid against the rest of the green and brown that it is outstanding to see. This one was highlighted by sunshine, but at night in the moonlight I can see why this is their common name.
I think this is a candlebark gum. I've read that these were given their name by early settlers because in bushfires the curled bark (that hangs down in long strips) looks like candles when it burns.
Stringybark - again named for how it looks, I would say. The younger stringybarks are not as rough but this one is older and wiser.
We also have peppermint gums and ironbarks, plus a few other varieties that I can't yet identify. One day I'll find a decent book!
