Thread: Ironbark, but which? Google powerless.

Any idea of the flowers, the habit of the tree, where it grew?

There are flow chatrs available for identifying species using all factors. I think state forestry departments may be able to help in that regard.

Locale and soil type where the trees grow is very important. In the MIA, for instance, the original soil maps were drawn up using the vegetation as the guide to soil type. Over the years they have proven to be remarkably accurate maps.

better pic of the wood.

there are now a lot of crossbreeds of ironbark that help to confuse the issue.

Artme: no idea, bought it at a club function. AFAIK ironbarks are not native of SA, could be a street tree but do not think it could be Mugga.

Carl, I tried but flash photos are even worse, maybe tomorrow. The colour of that photo is reasonable, though, just a bit pale because of the grey sky.

Sounds and looks like E. Crebra to me. Here is a pic of a tree I had:

and here are some pics of the wood......

Thanks Mark, that seems to be a perfect match. Looks like it darkens with age, then, a possible reason for the different description given for the wood by the various sources. Much obliged.

Carl, several times you have mentioned that there are a "lot of cross breds about".

Just wondering how accurate this is and what evidence you have.

Another question is "Why would this be so?"

i know a guy here that has a stand of what the glubberment call a pure stand of mugga iron bark and he is or was paid by them to leave the trees alone because there are not many PURE stands of mugga left , and was told that most are now cross bred with others , '
i believe the same is true of "callies ironbark ".
why i don't know ,

See a couple of references below and references therein, particularly Griffin et al 1988

I just googled "eucalyptus natural hybridization"

Will we have extermination camps to ensure "the purity of the race" next?

Thanks for the references, Michael.

Hit a snag. Tested a piece in a bucket, and it floats. E. crebra should sink (1090 dry and this is still rather green). Any suggestions? Could the urban environment (more water?) do that to a genuine ironbark? Or is it a mongrel? Just a day on the shed floor and it has actually become darker, the sapwood is a light brown now. Bordo's picture is still as close as it can get, though.

Was sample that floated sapwood? Sapwood is much less dense

No, I purposefully cut out a piece of the heartwood to test it.

Mugga is a beautiful tree and as far as I know ther are still large pure stands in several parts of NSW. Ther is quite a bit around Temora and out near Rankins Springs. There were stands around the Dubbo area too.
