Botany Acacia and Mimosa Identification Thread

Thankyou!

Reminder that there is no need to use bark with acacias, and a lot of the species in the wild that are active are now at high risk due to exploitation.

I'm sorry, what? Do you mean one can use any other part of the plant too not just the bark?

.. yes,twig and branch bark are equivalent to trunk bark, and phyllodes are technically an extension of the bark..

Hello, can anyone help me ID this ones?
They grow in the north of Spain, I have seen neither the pods nor the flower.
I was thinking maybe Acacia dealbata and Acacia farnesiana.

your first photo is Robinia pseudoacacia.. or black locust. Beautiful trees.. highly invasive around where I live. My house mate makes beautiful hunting bows out of the timber.. it is a prized plant for that purpose

The second one I am not sure.. I have a ways to go with the subtleties in the bipinnate species of acacia..it looks very similar to Acacia Irrorata..but will look more into some bipinnate species grown internationally

New item by Jack Jones is that confusa

 

[acacian]

Hey cola101

Thats a Eucalypt.. not an acacia.. confusa is not an Australian species so if you are based in oz you won't find it growing unless you grow it yourself. If you google search acacia confusa you will find many images of it to compare with your specimen... its quite different.

Also for future, there is a dedicated thread for Acacia identification in the collaborative research section. [MOD EDIT: moved it!] I'd suggest getting familiar with the differences between Acacia and other species first and foremost as that will greatly help you narrow down your searches... then in the beyond lies the next can of nuanced worms to open

Hey team can anyone help with id of this acacia. Thanks.

 

[acacian]

Hey Aum.. pretty certain it is Acacia longifolia.. will be going to seed right now. The only other contender would be obtusifolia but that is only just about to flower and will go to seed in autumn next yr.. it will usually have red resinous margins on the phyllodes whereas longifolia tends not to. it seems to have some intermediary qualities with obtuse but longifolia is highly variable anwyays so my bet is on that

I would test it as there are desireable varieties

could you get some clearer photos with close ups of phyllodes?

 

[acacian]

Hi, I'm only new here and don't know too much in regards to acacia species although I believe I am slowly but surely learning... I recently came across a couple of acacia I am uncertain about.. can anyone help me out

I think it is Acacia falcata

 

[Aum]

Hey acacian,

Thanks the reply. I was really hoping it was obtuse as I've never managed to find one yet. But if as you say it seeds in autumn then I can't hold out much hope.

I don't have any other photos as I was in a rush. I only stopped by that one quickly cause I'd driven past a couple in that area that all had the reddish tips on the phyllodes and thought I'd better check them out.

I will be back over that way early December so I will check them out more then. There was a nice patch of floribunda that I drove past near there that ill check out too.

 

[nen888]

..there are completely active, dmt containing varieties of A. longifolia (with red tips)...this has multiple confirmations, and these varieties should be actively investigated for seed...Aum, the species you were hoping to find is now so completely fkd up and butchered in the wild in many areas that we've lost valuable diverse seed stock for generations to come, if not forever..i earnestly feel, for its sake, that unless people are collecting seed, it should be left alone to recover..that would be the right thing to ensure a future for it in natural ecosystems.

(This is also the official Nexus policy on the species as reflected in the nexus-wiki page)

 

[Aum]

Hey nen888, I will be back early December to collect some seed and a sample.

Are you saying that red tipped longifolia could be more desirable than the regular phyllode or are the activity levels about the same?

I've never stripped bark or taken more than a sample from healthy acacias, ive planted a couple acuminata in the wild back in the day too, though I appreciate your conservation efforts. And I've looked online for obtusifolia seed before but I think most were out of stock or wouldn't send here. I will grow it myself one day.

 

[nen888]

hi Aum, there are longifolia with 0.3-0.5% DMT, so yes
and yes I get you're a respectful nexian, my comment is more for Australians..
can't find any seed online? that's probably because they've destroyed most of the mother seed trees ..yes it's that serious...
I wish all the other species a much happier and fairer time..

 

[Aum]

Oh wow i didn't know this about longifolia! I only knew of the old thinking that longifolia was around .2 and foribunda could be .3-.5. I will definitely collect some seeds next month. The pods were looking pretty green this week but I'm assuming they'll be okay to havest on my next visit.

Do we know if it's the reddish tip variety that is higher activity or have there been regular phyllode longifolia with reports that high? Or do we still need further investigation.

Yeah that is sad to hear. I see herbalistics has seed still but they no onger send outside aus. I'll have more of a look round online at some point.

Oh also is longifolia a species thats variable from rain or is it fairly consistent? As we haven't been going more than a few days without rain here most of the time of late.

Thanks.

Aum, there are also a lot of longifolia with 0.2, and more with zero - the higher percentage varieties are less common but exist, in a range of at least 200km, and perhaps more than one region.. the new growth can be an indicator..

there has been no adequate genetic studies and seed selection on these acacia species..
plants like tomatoes and broccoli have hundreds of years of European seed selection...potatoes have thousands of years of selection in Peru to give you the perfect chip...nothing remotely resembling this has happened with these acacias...there will be very desirable varieties of a lot of them (not just higher alkaloid, but faster growing)
the work hasn't been done, and a species like the one mentioned has had its wild genetic diversity extremely harmed in the past 20 years...

if you see an interesting tree, collect seed (leaving some for the land)

 

[Aum]

'More with zero' really? Man this can be a bit of a frustrating pursuit at times. Should there be that much variability or are people incorrectly identifying?

 

[Aum]

Has anyone here heard of a thornless variety of mimosa hostilis?

I got some seeds some time back in a trade on a forum that no longer exists. The guy was studying botany but couldn't tell me more about the seeds other than that he'd been told it was a thornless variety.

I don't have any photos to accompany, beside one of the seeds side by side. They look pretty similar.

Id put them away in a draw and forgotten about them but now I'm kicking myself for not sowing sooner.

 

[Aum]

Small bag is the supposed thornless variant

 

[nen888]

'More with zero' really? Man this can be a bit of a frustrating pursuit at times. Should there be that much variability or are people incorrectly identifying?

..this kind of variance is completely usual for many wild plants...the reason many well known European herbs are constant is because they have been selected...
any polyploid plant will have different varieties in preparation for different climatic conditions...
there are forms of obtusifolia with little to no alkaloids...in experience I would say 60% of A. longifolia contains tryptamines...others report more negative findings, but it may well be extraction methodology, or seasonal variation..as far as mis-ID, i've seen cases where supposedly negative results from A. maidenii were actually melanoxylon..

it only takes one or 2 seed suppliers to locate desirable strains, for them to quickly become widely cultivated, as more people collect seed from their initial plantings

But as far as 'frustration' goes, time and again I've stressed in the other acacia thread that if people are looking for instant DMT, they should grow or obtain Mimosa hostillis..the study of acacias is suited to those with a love of the plants themselves, more than an interest in simply tryptamines...

Hear hear!
