Botany Acacia and Mimosa Identification Thread

[kubizm]

South Aus.
Down the street further I found another 5 trees with similar flowers ,
All the pyhyllodes seemed to look a little different to each other to me.

As far as I can see there are no little hairs.

In that case, I'm pretty sure it's longifolia

..some good ID discussion going on..
with my limited time, let me add:

-Shadow..i think you have (on previous page) Acacia siculiformis..

SweetDreams..looks like may well be A. maidenii dominant (and perhaps a cross as you suggest) ..A. maidenii has a few sub-types (though not officially defined) ..active A. maidenii are very potent plants..
pods here are the key..if twisted/coiled it's maidenii..

ZeroSignal..does look like A. floribunda (mucronata is nowhere near as abundant in flowers)

and above does look like longifolia (kubizm)..

keep up the good work DreaMTripper and -Shadow..

 

[ZeroSignal]

Thanks for the responses, much appreciated. There are documented instances of A. Floribunda in my area (Eastern Victoria,) and it is flowering time for them. This quote by acacian is quite encouraging too:

from what I gather the type of floribunda you want has really creamy white flower rods rather than lemon coloured like you find in a lot of commercial strains. a lot of floribunda down here have more yellowy coloured flowers, though out bush I have observed a couple with the whiter flowers.. unfortunately one which I planned on testing I never found again - it may have died or been cut down... it also had a smooth trunk and grew more tree-like compared to the rough trunked more prostrate commercial varieties found growing in urban areas

if you can get the right strain it sounds like a great tree to work with

I intend to attempt an a/b on the phyllodes and stems of the trees I posted in the next few days, as they're very mature examples and there's quite a lot of them and I'd sooner avoid bark extractions for the sake of the trees. I'll post the results if successful or not, and if it works out favourably I'll look at growing my own. Thanks again.

hey guys , i found this tree today and i need help finding out what it is

 

[--Shadow]

Runner, look's like you're having quite a time finding various Acacias in flower at the moment.... I recently did the drive between Canberra and Sydney and you can literally see hundreds of thousands of Acacia's in bloom right now. (see below)

From you pic, it's hard to tell.... maybe some type of terminalis :? , is it possible to get a better pic of the foliage, including closeup of the leaf stems (pinnae)? (even a ruler in the background can greatly help with ID accuracy)

 

[kubizm]

as for the trees that I posted, what would be the best way to test to see if theres anything in them?
grab a bunch of leaves and twigs?
would be my very first time trying anything like this,
would the best ting to do just follow cybs tek?
cheers all

 

[kubizm]

So I went for a walk today near my new place,
Found a bunch of acacia's and got me excited,
I found the one exactly the same as I posted just before and saw it did have 2 trunks.
I saw a bunch of Acacia Pycnantha,
Here is another one I found, any idea on what it is?

 

[--Shadow]

Hi kubizm,

I even got to work lat this morning as I was photographing a bunch on newly discovered acacia's around my area.. I even found a.dealbata up the backyard of my parents house on Sunday.... I have not noticed it my entire life, but now that I am more 'aware', acacia's keep popping up everywhere.

I would say at least 90% of trees/shrubs you see at the moment (in Oz) with yellow flowers are acacias!


regarding your pic, for more accurate ID the best is to have a closeup of the phyllodes... could you get a better shot?

 

[--Shadow]

Can someone confirm if this is Obtusifolia?

 

[acacian]

do you have any pics of the phyllodes? i believe it does vary a little but the phyllodes look perhaps a little too narrow and lacking in the blunt tips and resinous edges? it definitely looks different to most obtusifolia I've seen

 

[kubizm]

Yeah sure mate.
I'll go for a walk in the next few days and take a bunch,
I remember seeing somewhere on here (I believe) that someone posted a link to a website that helps ID acacia's,
Where you pick like what the bark texture is like, same with the flowers and all that and it helps you narrow it down, like a interactive thing.
Sorry my description isn't the best haha, just wondering if anyone has that link.

 

[acacian]

yeah.. you should be able to narrow obtuse down pretty easily just through analysing the features of the phyllodes and flowers. obtusifolia has much paler flowers than the above photos.. a bit shorter too. and the phyllodes have blunt tips, irregular indenting (twisted sort of like) and red edges.. not sure what the website is sorry

 

[kubizm]

All good, I'll have a lurk around and Im sure I'll find it

 

[DreaMTripper]

This?

I know what you mean.

Have you tried the online wattle key yet?

Wattle2.2

A must have bookmark for your smartphone when out in the field:

Wattle2 Interactive Identification of Australian Acacias:
http://keys.lucidcentral.org/key-server/key.jsp?keyId=100

 

[kubizm]

Haha yes!
I just found it and was about to post the link too

 

[--Shadow]

So I've tried both versions of the Wattle key, but they both keep narrowing down to ONLY obtusifolia :?

Here's a closeup of the phyllodes. If you need anymore measurements or photos let me know and I'll upload.

 

[DreaMTripper]

The anastomisation looks very obtuse-like but the flower arrangement on the branch looks very maidenii-like, the blunt tips are clear in that picture. Possibly a hybrid of both and/or more? I will leave it to the more knowledgable and go and sit on the fence

 

[nen888]

^based on the look of and arrangement of the flower spikes, flowering time & colour, and also the look of the phyllodes (the veins, and lack resinous margins) i'd suggest a madenii x , like DreaMTripper..there may even be some longifolia in there..as i've mentioned in the info thread in the past there are some complexes going on in this group of acacias..pods and seed aril would help clear this up further..it's a nice find..

 

[--Shadow]

Thanks guys.

Yeah, I've got a feeling that hybrids are playing games with me....

For instance, this one below, all my measurements come out as saligna, but the gland looks like its at the apex of the phyllode like sauveolens ... could it be a cross of these two?
