Botany Acacia and Mimosa Identification Thread

[Trashipeoulas]

Hi Again,

I've found a few more acacias which I've had some trouble identidying. Could you please be of assistance in identifying these lovely trees?

 

[Trashipeoulas]

one more from the discovered trees from this weekend's outing.

 

[Trashipeoulas]

More Acacias. Anyone?

Hello again!!!

I have taken a couple more photos of the suspected A.Floribunda from the last page. Here are a few more pictures (and the original ones... Please let me know if you think it is a A.Floribunda!

The other photos are of another species I found today. I have been looking at lots of photos and believe it may be A.Maidenii. I am not very sure though.

Can you please do your best to ID them for me. Both of the plants are in the North Island of New Zealand!

Beautiful plants!

Thanks in advance for your kind help...

 

[floribunda]

So the first five of those photos I am guessing is A.Floribunda

The next ones starting from the picture with the pen (to give an idea of phyllode size) are what I am guessing is A.Maidenii.

If you can tell me exactly what they are I am going to be uber happy with you all!

Namaste

Sorry to say it isnt floribunda, floribunda. Im not even sute its an acacia, the others are I think and Im guessing they are melanoxylon( wrong bark structure for maidenii)

Trashipeoulas you didnt say where they are but they look like saligna or a variant of a.retinodes however my knowledge of acacia is limited. Have patience Im sure someone will study them when they have time and reply with their opinion when they can.

Thanks DreaMTripper!

Very strange about the non floribunda. I have three store bought small ones that look so very similar to this one! I was under the impression that if there is no centre vein on the leaf/phyllode then it is an Acacia! I obviously have a lot to learn.

Thank you for your help. I appreciate it!

 

[DreaMTripper]

well Im not 100% sure it isnt its just that the phyllodes dont look like an extension of the branches but now I look closely at the last pic it seems to have an acacia look to it so I would wait for someone more knowledgeable to chime in before any conclusions are drawn.

..hi floribunda..for acacia ID photos of the fully developed flowers, and close up of vein structure, as DreaMTripper says, are crucial..and pods (which take a few more weeks-months) nail it (as --Shadow said)
that said , the first tree may actually be an N.Z. naturalised form of A. floribunda..it is usually in higher country there..i would like to see the full flowers, and a close-up of where the phyllode meets the stem, before getting closer to a conclusion..
the second tree is A. sophorae/longifolia..
nice to see them across the tasman sea..thanks

and Trashipeoulas, hi..very nice to see aussie acacias in Europe..
the trees are A. retinodes (or A. provincialis, previously part the same species)
it has had one very interesting results by Nexian testing, and is common internationally..
along with A. longifolia it is naturalised in Spain, Italy, France, and the islands of Greece
.

thank you all the ID input people of the thread..
.


and everyone..please remember to be kind to trees..

Thanks Nen888!

Looks like flowers might slowly be forming on the suspected NZ Floribunda.

I will be sure to upload photos of them when they do.

Do you think there is any point doing an A/B on the phyllodes or would the Longfolia bark be a better bet for research?!?

Big thanks :thumb_up:

 

[DreaMTripper]

Not bark from any wild tree it weakens its defenses significantly, so much so it can and probably will cause a slow death of the tree due to infection.

 

[floribunda]

Of course not. The A.longfolia var has had some big branches chopped off it by the council and there is a lot of bark to be had. Just wondering which would give me more luck out of the potential floribunda phyllodes or the bark!?!

Hopefully I can get some flowering photos soon!

My Acuminata seedlings seem to be coming along quite nicely!

 

[DreaMTripper]

Branch bark is likely to have more alkaloids than the phylodes.

 

[floribunda]

So branch bark from A.Longifolia var Sophorae is more likely to contain some sort of spice than phyllodes from A.Floribunda?

Sorry about these questions. Very new here! I appreciate the help.

 

[DreaMTripper]

Both strains are variable (flori more consistent but that could only be due to the lack of research done on sopho) so noone but the trees could tell you.. Bark generally has higher percentages but there are no guarantees.

Most times I've extracted from A.Floribunda I've had success to some degree. Goo and later some crystals. Branch bark has worked better than the Phyllodes. I've found you need to separate the inner layer from the outer layer of the bark. The inner layer has a red colour to it similar to root bark although you are probably not going to be afforded that luxury unless a larger branch is cut off - which in my case is what happened when it was being cut back from a fence line. That is what seems to hold alks from my experimentation with Flori.

From memory though, most of the success was around ~November. I've tried an extraction from the same tree in one of our winter months and came back with absolutely nothing.

Thanks heaps for the helpful information. Would cybs salt AB tek be a good starting point for both phyllodes and bark on these species?

If this is off topic I can post it somewhere else

Helpful bunch you are!

Cybs salt tek is exactly what I tried. Flori tends to naturally have a lot of plant fats or oils and needs a cleanup for crystals. You'll just end up with pretty nice goo without a mini a/b. Not that there's anything wrong with that!

Today i found out that a acacia that i planted on the ground in a semi-remote area and that i started from seed some years ago (not sure if 3 or more years ago), has survived winters and summers and is doing excellent! Really happy for it and for me cause i was losing hope that i would ever have a green thump for "exotic" acacias.

So my problem now is this: at that time i brought i think 3 packets of acacia acuminata, some narrow and some broad phyllodes, 1 packet of acacia mucronata and i had few acacia longifolia wild collected seeds that i sow too.

IMO the phyllodes feel different and look different too when comparing to longifolia. This is my only point to compare cause i only know from field inspections, longifolia and melanoxylon.

So could this be acuminata broad phyllode variant or is it longifolia?

Thanks
