Botany Acacia and Mimosa Identification Thread

Growing logs with advice and results.
Migrated topic.
Trying to keep these plants hidden will make collaboration hard between people who want to regen these areas. Call me "The protector of the north".

Another point on Floribunda people.. YOU CAN CLONE IT!! One of the few Acacia that you can.. ITS MADE FOR AUSSIES! Spread the word.

Viva Floribunda !
 
Hi Everyone SWIM is new here and hoping for some Acacia Obtusifolia ID help from NSW in the land down under.
Signed up the other day and have been researching for countless hours. In that time and the research SWIM has done on DMT he has a growing appreciation for plants and trees that he never had before :d

SWIM spent a couple hours searching one location today and had no luck as the ones he thinks he found were too sparse and seemed young. He read that these are becoming rare? So he left them.

So on his way home he decided to take a chance and turn off and check a spot and right away SWIM found them! He really hopes this is it because he happened to stumble across a number of fallen/broken examples. As it was fallen and parts dying SWIM removed as much of the bark as he thought he needed. It is not flowering but hoping this doesn't affect the content and can use it?
Here are some pics. Cheers :thumb_up:





As SWIM has not obtained all his tools is there anything he should do as far as storing/drying prep etc.
Thanks again
 
Hi Hazey82, welcome to the Nexus.

I haven't ID's your pic yet.

Are you looking for someone to ID an Acacia Obtusifolia, or do you believe you have an Obtusifolia (of the more than 1000+ species of acacia) which you want confirmation of?

Just wondering, is Obtusifolia a species of Acacia you are specifically looking for, or do you know of the many abundant other species that are also active?

Obtusifolia is a species that has just recently been unethically harvested in national park area.
I'd be more incline to leave it until the seed have ripened, then go for the small twigs and leaves in a sustainable manner
 
In the first instance looking for ID confirmation of what my pics are. I believe it to be Obtusifolia as it hasn't flowered yet therefore its not Longifolia as I know they are very similar. I'm very open to other active species in NSW but from my research I only came up with Obtusifolia and Maidenii with Maidenii being inconsistent in its active content?

Thanks

..i had started to get an uncomfortable feeling about some of the recent requests to ID obtusifolia..these were confirmed when a few days ago i saw the worst case of destruction of this species in a nature reserve/national park i have ever witnessed..in it's native environment it is neither common enough or fast enough growing to withstand this assult..in a pristine environment every single large tree, around 50 of them, (based on growth rates, at least 30-40 years old, some more) had been completely stripped, ringbarked, left to die with phyllodes still there...the waste, ignorance, greed and disregard for the future of the trees or environment were stunning..all mature trees left dead or dying, where are the seeds going to come from?

i will be going into this more in the acacia info thread soon..

in the meantime, i'd like the various new members who made obtusifolia ID requests to post their perspectives on ethics, sustainability and environment..


someone out there knows who did this..

they have killed the hand that feeds them..and seriously affected an ecosystem which needs these trees..

this post doesn't really convey the sadness and shock i am currently experiencing..
and i am very concerned at the unintended harm a thread like this may be having on wild environments..

obtusifolia is in trouble...for it's own future generations, and for those who would like it to keep growing in undamaged native environments in new south wales..

this happened sometime in the past few weeks..
seeing it was one of the saddest days in my life..

That is really disturbing to hear. Obtusifolia isn't exactly easy to grow. I have two that i've been growing for almost 9 months now and they are barely 6" tall. Contrast that to the several A.Maidenii I've grown from seed which happily grow around 1m a year and Floribunda which is very prevalent and certainly active, there just isn't the reasoning to do that sort of thing. Exctractions are prefectly successful from twigs, phyllodes, fallen branches etc. There is more than enough material free floating around.

I've often throught about planting many of the seedlings i've established out in the bush but for this very reason I've stopped short. I haven't even had the heart to clip my own trees.

I personally cant fathom the destruction of trees in their native environment. People need to watch their own grow from seed to fully comprehendand just how long an established tree takes to mature. There are some species I can't even get to grow like A.Confusa. Sadly people like this are motivated by monetary gain, not ecology, spirituality or the journey.

The main difference between A.longifolia_var_longifolia and A.Obtusifolia, are the tips (apex) of the phyllodes.

Longifolia is pointed
Obtusifolia is blunt (or "obtuse")
 
Hello and good day, I just went out to the mountains here in sinai and found this tree..I hope it is an acacia..

What do you think about?

Seems to have a similar growth structure to the desert acacia pictures nen has posted before but you could probably narrow it down easily enough by geographical region as there doesnt look like many of them there!
Could do with a close-up of the phyllodes.
Have to say its defensive spikes are superb.

I found it in the southern of Sinai, near to Dahab, (south of the st. caterine monastery) where is also the famous burning bush of moses. south sinai is full of this trees...

in the part of the world you are in, you probably see the following mimosaceae...there are 4 native acacias around there, and then quite a few introduced (mostly australian) species brought in years ago for reforestation/desert reclaiming.
Acacia tortilis
Acacia saligna
Acacia raddiana
Acacia victorae
Acacia salicina
Faidherbia albida
Leucaena galauca
Leucaena leucocephala
Loranthus acaciae
Vachellia gerrardii
Vachellia farnesiana

which one of those have the most dmt in it?
the tortilis is the one i saw so far till now
 
Hi nexians and acacians!

I went for a bit of nature stroll this afternoon and thought I'd be on acacia watch and try and sharpen my viewing and ID skills. It was in a conservation park adjoining a local suburb in SE QLD and was also under weed management. I found a few different acacia species and took some photos and carefully took a few little branch tips with phyllodes to help with ID. I also just did a web search on the conservation park and found a local council PDF that listed the species in the park. 5 acacia species were listed and through viewing my photos and some online sleuthing I've narrowed it down to what I think are acacia longissima and acacia disparrima. The first three photos is what I think is longissima.

The last is what I think is disparrima.

I would love to hear some other acacian nexians opinions on these, I quite enjoyed the walk amongst the trees!

Edit: Just to add, I would only be taking phyllodes from the acacia longissima (a few reports of 0.2% tryptamine in the phyllodes), there was plenty of them I found on my walk (or what seems to fit their description) and could easily harvest small amounts from a variety of them to hopefully sustainably harvest and not cause any lasting damage to them. Please correct me if there is a better way to go about this, or even if I should just leave them alone if it's better for them in the long run but from what I can gather from my research, harvesting phyllodes in modest amounts shouldn't cause any harm to the trees right?

I went for another walk today in the conservation park from my above post in SE QLD to explore a bit further and see if I could spot more acacia longissima and found some more mature specimens (at least what I think to be longissima) at around 3-4 metres tall. Again I took a few samples of tips of branches to see if I could get some help with ID's. Unfortunately there wasn't any seed pods but the phyllodes and flowers seem to fit the description. Please find some photos attached below.

I know seldom and nen have some experience with this one if you guys want to throw in your opinions. Merry xmas guys!

Hello Forum ok i went out again in the Sinai dessert and found a other tree which looks to be an acacia but i cant find exactly which one. I found online many pics with trees or acacias and flower like that yellow one but not sure which tree that should be... hope to found an acacia and a good one to make some tests on it ;)

The whole tree

similar to it are this acacias.

Acacia Flava

Acacia gerrardii Benth

and this one which looks for me also for the seed pot the most similar to my pictures

Vachellia farnesiana

Ok the last time i found this Acacia Tortilis, like here at the first picture you can not see it easy but at the down right site nearly to the corner you can see a bark coming out the sand...

i get a piece of it
IMG-20141226-WA0002.jpeg


Cut it in parts
IMG-20141226-WA0004.jpeg


Take of the root
IMG-20141226-WA0006.jpeg


And made smaller pieces for the grinder

and now im hoping to get out some results from the bark, ill take the outer and inner rootbark.

lets hope :)
 
At least a lot of Acacias exude a sugary substance . Ants like it . I've read about them liveing off / with the help of ...... and i think even in symbiosis with Acaias in africa .

I had what i think was an Acacia Maidenii in my apartment . Ants discoveed it and made a nest in the roots and lived there just off the drops from the shoulder of the leaves that it exuded ........ and ...... they cut mini holes in some of the leaves and ate the sugary substance that came out . It didnt seem to harm the tree .
 
I can't be of much help with the ID but I can surely share my experience with ants, plants,and symbiosis... One of my large Banisteriopsis caapi plants which I keep outside became inhabited by black ants and did little to no harm. They were feeding and living off of the sugar liquid it secretes from the underside of leafs, making them both stronger because of it. Ants would protect the plant, and plant would feed the ants.
Definitely a neat relatonship.
