Botany Acacia and Mimosa Identification Thread

[cave paintings]

Snapped a couple pictures in passing of this guy, apologize for poor quality. Never seen this one around before, didn't even notice it til it bloomed over this weekend. Much more of a tree compared to all the bushier kinds normally around. Foliage is very mesquite-like.

..re shanedudddy's first pic in #295, i would say it's Not A. victoriae, based on the seeds and phyllode (of other photos earlier)..the seeds should be noticeably 'mottled' (speckled) and the phyllode has a prominent central vein..i have attached key ID images in the info thread..

it is probably A. alexandri , A. aphanoclada , A. chartacea , A. cuspidifolia , A. dempsteri , A. glaucocaesia , A. pickardii , A. ryaniana , or A. synchronicia ( the ‘A. victoriae group’ ) but i don't have time to go through each one..

the cyclopsy candidate does look like cyclops..it can have variation between more arid forms and more coastal forms..but it is not unlike one form of melanoxylon..a few more photos showing more of tree, plus close-up phyllode, and close-up of seed aril in pod would help..if all flower balls are in pairs is cyclops..it already has suggestion of variability naturalised in sth africa (low after rain) so good luck with experiment..

^ It looks like Acacia Elata to me Seldom.

beautiful, thank you!

Hi I have 2 wattles which I have no idea of what they are. Location is NSW mid north coast. Could someone please offer any ideas? Sorry for the poor focus and thanks in advance again!

Hello! can anyone help with identification of this tree?

this plant looks very similar to what i'v seen on the web, but still i have doubts

it's winter time so i can not post photos of leafs but they are similar to this plant leaf
i guess this is Acacia but which one? is this one good for extracting DMT from its root bark?

 

[nen888]

..cave paintings most recent is Acacia decurrens..(no known alkaloid results)

Seldom has A. elata as WAGE said..that tree can be mild or as heavy as it gets, tryptamine-wise!

and unik..the first is A. melanoxylon..the 2nd really needs flowers and/or pods to have any chance of ID (as is the case for most acacias)
.

Thanks nen, appreciate your help. I'll continue to try and bring my knowledge up to scratch. I've read melanoxylon has little to no alkaloid content. The one in the picture was massive with a trunk like a tree (had to be cut down as it was casting an afternoon shadow on a few solar panels) so a large amount of bark on the trunk and branches. Worth attempting an extraction? A/B with Hydrochloric, Sodium Hydroxide and Naptha? Sorry if this is the wrong thread to be asking these questions.

 

[nen888]

^..unik, this is the site for questions (and hopefully answers)
while i've never gotten much if anything out of melanoxylon (similar to a few other people), i still feel that some trees sometime could..but it can be disappointing to go through a whole process for nought..if the phyllodes are really bitter could be worth it..
also, don't use Hydrochloric acid for acacia A/B..can react strangely..acetic (vinegar) or sulphuric work well..

but it can be disappointing to go through a whole process for nough

I know this part oh so well :/

G'day

One of my mates bought an Acacia about two years ago and it was labeled as a Acacia longifolia sallow wattle, but it looks different to longifolias that I've seen & grown. The picture on the tag seems to be a good match to the plant he has, so I'm wondering if there is a narrow phyllode longifolia or if the plant could have been mislabeled.

The mature phyllodes are 6mm wide and on average 140mm long.

 

[Parshvik Chintan]

wondering if you eagle eyes can confirm my thoughts.
the pictures are from maui.
the top is what i believe to be mearnsii (it didn't have phyllodes, but i read mearnsii is invasive on the islands, and that sucker was everywhere, the flowers seem a match, but the pods don't[?])

the next below it i am fairly sure is kiawe (mesquite).

i had pictures of what i thought was monkeypod, but it looked essentially identical to kiawe without any thorns, flowers, or seed pods.

i also couldn't find any kiawe pods, but i am almost positive in that I.D.


also, i managed to collect rootbark (inner and outer) samples of all three suspects (it was just too easy, they almost all had horizontal roots exposed above ground); but i am not quite sure where to go from here..

can any smart people break it down for me in a way that isn't completely over my head?

 

[acacian]

hey parshvik .. sorry unsure of what species they may be, though the first one is definitely not acacia mearnsii. mearnsii has a bippinate phyllode structure, and the flower globules are much smaller... here's a photo

 

[Parshvik Chintan]

huh... well that stuff grows all over kauai and maui, probably the other islands as well.

when i go back i will make sure to collect lots of samples, as most of those were smaller shrub-like trees, and i collected my rb from a HUGE tree that i am 99% sure was acacia.

it wasn't flowering but i think the only acacia other than mearnsii on the islands are koa, and i am pretty sure it wasn't that (really white bark)

#1

#2

Can anyone give an ID on any of these? I'm unsure if #2 is even an Acacia.

 

[Blackandblue]

Curious about these bad boys ^^ from metropolitan melbourne

 

[Blackandblue]

Is that...a fruiting body? There's a disgusting growth all over the small tree

 

[nen888]

..Parshvik C..the plant that isn't A. mearnsii is actually very interesting indeed..will have a think about it..and yes that's a mesquite lower photo..

mesquite is safe for bio-assay, yes?
