Its growing in south east queensland
Its from a tree over 10m tall.
It has a small thick straight seed
Little round ball flowers
80% of the leaves have a red resiny colour to the outside of the leaf and a lot of them are very insect damaged.
It has about 5 longitudinal viens, not very prominent and vey little anastomosing.
I have noticed a few small possible suckers around some of the trees

not sure what you've got there.. but the red resinous edges is a good sign. should test it

Acacian I have plowed through every web ID site it is doing my head in.
I have a smaple that I am going to give a run today, I was just hoping maybe for an idea before I got stuck into it.
I have tried quite a few plants lately some I knew were not maidenii and a few I knew that were. And all have been with nil results. Getting a bit disheartening, just hoping maybe someone knew before I dive in again.
Never the less if I ID or I get some positive results Ill keep it posted here.
Cheers

"Acacia longispicata is one of the taxonomically 'difficult' group of species that also includes A. concurrens , A. crassa , A. leiocalyx and A. tingoorensis . These species constitute part of the 'A. cunninghamii group' (see A. concurrens )."

I've never been able to ID between these species or spent much time on them.

Your best bet would be when they are in flower... a couple of them would likely contain DMT in small amounts at certain times of the year, and I believe there are positive alkaloid tests for Concurrens out there, as they are also in the section Julliflorae with Anastomising veins.

You are best off doing the testing of the trees, when you find DMT, reverse engineer your results, then take your samples to the Brisbane Herbarium if you really want to make sure of its ID.

Nobody has really cracked the code of the SE QLD wattles as far as I know!

Thanks Choco, I have a pretty hard time IDing them as well.
Im not sure on your ID. If you have a look at the ball flower in the first photo I think it counts that ID out.
I thought it might be a Melenoxylon, but the seed pods don't match, second photo, especially as I could locate what I thought of as suckers. But not so.

oh yeah, didn't see the flower.

Could be implexa. it is quite a common one.

Thanks again Choco, been down that road as well, the seed pods (pic2) dont match and what they call pruinose(ing) does not occur on this tree. Im not trying to be difficult I do appreciate your help, but like I said to acacian I have been trying to ID it for a couple of days and using my mothers ( a horticulturist) books on the local acaias and some come close but then something will throw it out again. What I cant find anywhere is the red resin colouration on the outside of most of the leaves.
Thanks again C

Take it to the Brissy Herbarium, it only costs a little to get them to ID it.

Thing is, these trees often create unusual strains, which are not in the botanical textbooks.

I'd say it is a strain of Implexa.

test 200 grams of fresh phyllodes and let us know what you get out of it!

yeah it does look a lot like implexa.. flowers are much more yellow than the usual creamy white. hybridisaiton gets so confusing

have you extracted from implexa choco? its one i've had my eye on for a while but havent gotten around to it yet

Ill make this quick as Im not sure this is the place for this.
I had quite a bit of this tree as we have had huge winds lately and there was a fair bit laying around
Prelim result...
400g of branch bark
Did 2 citric acid boils(pH4) x 1.5hr each
150ml of xylene to defat
150g sodium hydroxide in 1L into soup x 700ml (pH13-14) very nice black soup.
3 x 300ml shellite pulls. I have decided to use sheltie as im saving what naphta I have. And as I dont know how to identify good goo yet, after some suss results I am just going to go for the crystals till I am more experienced with knowing what I have.
First 2 pulls came out very milky with the 3rd pull a lot clearer.
there was a lot of suspended white stuff after the first 2 which took a long time to settle out.
After quite a few attempts lately I am reserving judgement.
Cheers for the help guys

Yeah, you always have to wait until it dries to see... looks can be deceiving.

btw, defatting is unecessary. a big waste of time. its just an old tradition that people do because some dude in 2003 said it was necessary, but if you do tests you will find it doesn't make a difference.

dunno why you use xylene when you can use tolune, it is found in some hardware stores in capital cities (try some mitre 10 stores)

also, shellite in Australia is SHITE atm, I swear it worked well five years ago!

>have you extracted from implexa choco?

Yeah, years ago. nothing. but a lot of these acacias are seasoanal.

Choco, what do you use instead of sheltie

Toluene. best for testing too as shellite will often just pull almost nothing. zippo lighter fluid works better! (or generic $2 shop variant)

So whats the difference between Xylene and toluene? Whts the end product of toluene?

Toluene is less toxic. Toluene pulls a good which then crytallises into a opaque crystal.

Thanks for that.
Do you evap or freeze??

you can't freeze precipitate with toluene.. or xylene. it must be evapped

Thnks again Acacian

Right so I have poured the shelite and it has left some brown crystally stuf and some ice looking stuff. Bith completely separate. I have it draining upside down in the freezer now. As when I pulled it after already draining it its started to look sweaty and turn to liquid again
Any tips on what to do after I have drained it updise down and the freezer perspiration starts to liquify?

Ok so I think I have a positive id on this one. I should have included a picture of the tree.
But Im 99% sure its an acacia harpophylla, common name- brigalow. And there are a few crystal formations after the clean up last night
