Well Artme, I took an approximately 20 mile x 20 mile region near your tree and produced that list. You sure ruled out those species fast!

How about this list!!!

I looked this up and was quite excited as it is not a common tree. However when I spotted the stand I was quite certain that the
trees had been wrongly identified. The leaves did not have the appearance of A. bidwillii. A. bidwillii has a feathery leaf. These trees
have short leaves about 30mm long and slightly less narrow, They have the typical appearance of many wattle leaves like Sydney
golden wattle and blackwood in that they have prominent veins, and are a fairly deep green.

The trees are native to this area, are about 6-8metres tall, have a dense bark about 10mm plus in thickness and the timber is very light
in colour (which is pale yellow) with no differentiation between sapwood and heartwood. The timber is dense. Seed pods are about 60mm long
and 30mm wide with a double row of seeds. They are quite flat pods. These trees are about 100-120 years old according to the property owner.

I didn't get photos but will try to in the next few days. I will also ask about flowers and find out who identified the trees in the first place.

Any idea from the brains trust??

Hi Artme:

The Acacia bidwillii is as you describe. Acacia sutherlandii also is a bit like that in the bark and pale wood. Both are central / northern Qld species from my experience ,... both with pale woods (ie no noticeable dark heartood), very prone to green stain fungal attack during drying. Wood is heavy when wet. BUT, as you say, both have ferny leaves not phyllodes (eg like blackwood).

As you probably know ferny leaves are the true leaves of Acacias and with some (eg blackwood) they change from ferny leaves in juvenle trees to the familar flat leaf (called a phyllode) of mature older trees.

Here is a link to turning some corkbark wattle wood.. but seems like not a good wood to me.

There is another dryland Acacia with a corkybark like those above, A coriacea now A sericocarpa ( see http://plantnet.rbgsyd.nsw.gov.au/cg...a~sericophylla) BUT this one with a pale sapwood, thick spongy bark and long strap like leaves, and dark heavy heartwood.

Another one that grows in the Kimberly with a corkybark is Acacia suberosa but it also has ferny leaves.

So I reckon its a watlle species from your description but which?

Thanks Euge!!!

Trees are certainly no a. Sericophyla. I have not had a chanc to get back and take photos as we are off OS next week.

I figure when I come back I might wait until the trees flower again so that will give an extra pointer.

The boys slabbed a couple of lengths and stored it on the mezzanine floor at the club. I wasn't about to get a ladder to climb up and have a look!

I am told the pieces cut nicely and the grain is interesting and pleasant but not spectacular.

A mystery yet to be solved!
