looks more like a fern

A fern indeed.. probably best if people do at least a a little research in regards to what defines an acacia or mimosa... this way the thread won't become cluttered with other random species and we can get down to identifying acacias

..obviously legumes are in the right general ballpark so I think members can be forgiven for posting them here .. (as the differences can be subtle to the lay observer)

Lupis Arante, your tree looks similar to Acacia Cincinnata.. but some more photo's would be good.. especially of the phyllode shape.. it could also be Acacia Disparrima

Acacia Cincinatta will have minor nerve anastomy between the three prominent veins.. while Acacia Disparrima's veins are longitudinal.. its hard to tell from your photos, but it looks like some nerve anastomy is present.. and the way one of the prominent veins is confluent with the phyllode margin suggests probably Cincinnata.. though it is less common than Disparrima..you'll know for sure by its pods as Cincinnata's are coiled while Disparrima's are straight slightly curved

a lot of the wattles up in that area look very similar.. I'd suggest having a look at Wattles of greater Brisbane region ..

So this is 90% Acacia Prominens, but it is so far away from natural habitat I can't be sure. I'm in melbs.
Where it grows, it is by itself in what looks to be a garden bed out the front of a factory that has long since been converted into a yard - in an industrial area. So I'd say he was part of a landscaping jobby.
Anyway the winds we had the other night cleaved a hefty limb off the side. A gift
I commandeered what feels like 2kg of phyllodes, flower tops, twiglets etc.

This tree has been away from his homies for so long, a fish out of water.

Thank you for the fantastic resource Acacian.

I do have one more ID which I seem to be having a fair amount of difficultly with.

Thanks again for all your help!

Those are seed pods that I have never seen on an acacia before, if they are actually pods.

Acacia maidenii in NSW seem quite different from the Vic species, much thicker phyllodes not papery, rougher fissured bark not smooth however seedpods are the same. The ones in NSW have closer resemblance to a.melanoxylon, from Vic!

Almost 100% sure these are maidenii..

Lupis Arante, your latest photos are probably Acacia Disparrima.. note the shape of the pods. should have numerous longitudinal veins non anastomosing

And DreamTripper .. interesting maidenii if it is one.. I thought maidenii had more of an acute apex but my understanding is that its a highly variable species.. even just within NSW.

I also wouldn't rule out Acacia Melanoxyn as the ones up here are also differen't to those in victoria .. and again, its also highly variable within NSW. Certain strains of melanoxyn (eq in the new england area heading east) have smoother and lighter grey trunk bark, as well as narrower/more acute phyllodes .. which can lead to being mis-identified as maidenii... it doesn't always live up to its name "blackwood".

It just finished flowering where I live.. so one can tell the difference from the dead flowers still present on many.. but my observation is that some trees further south flower earlier than up here; so depending on which area of NSW you are in you may also be looking at a melanoxyn that finished flowering some time ago. Pods are coiled with melanoxyn too which makes it even more confusing.

Hope your well

Ah didnt know that! I previously thought melanoxylon had much straighter pods and that was how they could be differentiated, now I am leaning towards melanoxylon because of the rough bark..I wonder if they hybridize as some of the young ones have almost the exact same growth structure as my friends in Vic that is a confirmed maidenii yet the seed mother again looks vastly different and more like a melanoxylon in my previous pic.. Thats not to say that is where they came from but the distribution around that full grown tree suggests as much. The plot thickens..

See attached for example of the growth structure..

I'm unsure whether you get hybridization between the differen't sections.. I don't see why they wouldn't .. but I am young in the school of acacia.. a juvenile acacian and they like to surprise me.. Very thick plot when acacia is involved .. we can be sure of that!

Hey guys,
Found those in northern NSW. Anyone knows what it might be?
Thanks

Yes that is a.blanka.

Acacian, you are a legend. I am struggling to find much information about the alkaloid content of this species. My guess would be it has little to none or there would be much more information. Can anyone elaborate on information gathered about a.disparrima? Has anyone done a regent test to see if trace amounts are identified/ anyone done an extraction?

Thanks again everyone!

I think that pretty much anything within section juliflorae (rod flowers) is worth a test.. Nerve's are a hint too

And I'd say your guess may well be wrong as many acacia's are untested.. they are a pretty juvenile area of research. also keep in mind that some researchers may not be vocal about their findings in care of the trees. if your gonna test it just prune some twigs and phyllodes they will be a good enough indicator.

does the tree draw you in? thats really what it comes down to I think..

good luck

You recommend doing an A/B on some twigs and phyllodes?

I'm not entirely sure what you mean by the tree drawing me in. It did catch my eye and I felt the need to investigate its species... So I guess so?

Yeah I'd do an a/b .. maybe get around 200g of material. yeah that was what I meant ^

I usually use cybs hybrid salt tek, thats based on 50g of material. Do you think that would give an accurate measure? Or have a way to extract the alkaloids in order to decrease plant material to 50g? Sorry for so many questions, you are an incredible source of knowledge. Thank you very much.

Well the thing is their yield may be significantly lower than other well known yielding acacias so using the amount of material you normally would with a high content plant like confusa(?) may behave much differently and yield next to nothing (or not!)..

Using around 150-200g of material means that if it is a lower yielding species then you will still obtain some extract.. if you only used 50g of material that only had say 0.2-0.3% alkaloids you won't yield much even if it is active and may make the assumption it has nothing in it... and with an active phyllode species 0.2-0.3 is no big deal as its not so harmful to harvest a few more phyllodes.

think of it as a more concrete way of knowing its yield.. or a "safeguard".. if the yield is active but negligable then try testing it at other times of year or in differen't weather conditions and if its not worth using in any of those conditions then you will know its not worth pursuing .. but still worth admiring

Wow, I hadn't really though of it that way... Thank you for the new outlook.

So would cybs salt tek still be viable with increased plant material amount? or should I be looking for a new tek?

One I would like some help with.. it was found growing on the border of the warrumbungles. flowered early-mid september so I'm guessing its pods are probably near fully formed now. Had a great character about it (its the sexy one in my avatar)

as far as I gather it is part of section plurinerves.. the apex of the phyllodes was very sharp! similar in appearance to a. venulosa but no anastomy present and the flowers are arranged on longer stalks as opposed to those of venulosa which grow closely along the stems

hi,
sorry about that blank post the other day, phone issues. lets try again.
