Acacia Identity

Question

Hi Folks

Could someone help with a definitive identification for this species.

Found in the heart of the Nambucca valley 5 km from the coast in National park (mostly re-growth after fire a about a decade ago).

Sample taken 2 days ago

Some have tentatively identified this as Obtusifolia...(which would be nice to know as there is a lot of it growing :wink: )

kind regards,

Acacia obtusifolia (below)

Acacia_obtusifolia_1.jpg

Acacia longifolia (below)

Acacia-longifolia-branch.jpg

i'm glad you can tell the difference Glaukus.

they look almost the same to me, very hard to tell apart

I did a bit of research on wikipedia (where i got the pics from) which i'm sure you already checked out Flux, and apparently they are both closely related. here is some good info from the site that may help identify both plants.

Acacia obtusifolia can be distinguished by it having phyllode margins which are resinous, it usually blooms later in the year and it has paler flowers than Acacia longifolia

I'm unfortunately no expert, and wish i could do more than post some info of the net.

But i hope this helps anybody reading & U 2 Flux.

^ The reinous margins aren't always apparent on obtusifolia, particularly in winter. They do appear resinous (mine do anyway) during periods of rapid growth.

& obtusifolia normally flowers around December where I am. I've never seen one flower in your zone though, so that might be a key to help with a positive ID.

Thanks Baghdatis, I’d looked at the Wiki sites several times, but it really helps to have the two side by side like that.

Having collected these photos today (from other locations), I have noticed there is no resinous margin and the seed pods posted above are definitely from these trees. Included is a photo of the bark if this helps. I also tried a burn test but no distinct tryptamine smell.

These trees vary from around .5 metres tall to at least 2 metres- some 3

Glaukus & Sally are gonna be the ones who will be able to help you out with this.

Glaukus made the call with longifolia in you first post. (which looks to me to be correct)

And Sally actually grows obtusifolia. (& could even edit a wikipedia post, and i quote. "The reinous margins aren't always apparent on obtusifolia, particularly in winter. They do appear resinous (mine do anyway) during periods of rapid growth")

Seems to me they have more knowledge on this than you can poke a stick at :worship: .

Your new pics of plants, you say vary from around .5 metres tall to at least 2 metres- some 3

Look to me to be the same species as the ones in your first post. (Acacia Longifolia)

Although your third pic (the one next to the seed pods) still has me guessing.

The leaves look much more narrow, and flowers much paler than the rest. - Anyone able to help out?

I went through this list from wikiepdiea https://en.wikipedia.org/wiki/List_of_Acacia_species

The closest thing i could find matching the pics of your illusive friend was.

Acacia suaveolens

Acacia_suaveolens.jpg

Acacia-suaveolens.jpg

But once again unfortunately I'm no expert, just what I'm getting of the net.

I can't say for sure what it is.

Anyone able to help me/us on this one?

Hi folks,

Some new finds today which I suspect to be Obtuse & Floribunda - any thoughts ?post-15456-0-67234800-1437803761_thumb.jpost-15456-0-84352600-1437803766_thumb.j

I can't see enough detail in the second pic to make a guess.

The first is definitely not obtusifolia.

Not sure about the first, but I agree that it's not obtusifolia - could be floribunda though.

The second could be fimbriata.

Sorry for my late input, but yeah no way are they obtusifolia leaves are way to short, narrow and numerous, as the sally and the Dr where saying looks to be floribunda my other guess would be aneure but the flowers are a bit more yellow then the ones you have there,

second pic is a bit fuzzy but the Dr looks to be on the ball with fimbriata but more pics with more detail always helps.

Acacia floribunda

Acacia aneura

Acacia fimbritata

yeah and apparently You are not allowed to use that image extension on this community. WTF?

Thanks Baghdatis,

As I become more familiar with what's in my area, I think A. floribunda and Fimbriata are the call...the former being the more prevalent and having quite deep red bark and very fine twigs that protrude from the main branches (which should serve nicely for a test sample).

Additionally I have another curious specimen which the closest match I can find seems to be A.Binervia (more commonly known as the Coast Myall, which makes sense as it was found in a remote part of the Central Coast). Attached are some images of this significantly tall, slender tree with very flaky bark.

Hi folks,

Latest finds are posted below; I suspect I am getting closer to Obtuse in the first two (small 1-2 metre plants with no flowers or pods to as yet) ...and the rest Maidenii ?

Flux, not sure where you're at, but obtusifolia should be starting to flower right now. If you're seeing flower formation you'd be on the money.

Mid North Coast...and yes I thought they should be about to flower, it's been very warm-but could be even a week or two perhaps ?

Small specimens like those may not flower, which makes it hard. The ones in my yard are about 2m tall and no sign of flowers this year. But in the bush below my house it's yellow fever!

Good to know :) It will certainly make the larger ones easier to spot...going walking up to a spot which is also well documented on GBIF < http://www.gbif.org/species/2980237 >. Have a small test to run on the above Obtuse species (all previous attempts with Longifolia, Floribunda and what I'm suspected to be Longisssima have been negative (other than for learning the ropes)
