A.Obtusifolia Identification

Migrated topic.

Hello Everyone!
I am a new member of this forum but I have been surfing through these topics for a good couple of months now. AFOAF used the search function more than once but wasn't able to get 100% satisfaction from what he found.
he has been trying to find some DMT containing acacia obtusifolia in northern NSW (Bellingen-Coffs Harbour-Byron Bay) but has been having problems identifying those trees he thought could be A.Obtusifolia.
here I am posting some pictures of little young shootings AFOAF found around the area, hope someone can help him out! :)

PS: AFOF noticed the bark on the trunk and older branches was grey.

Update: AFOF found a new tree of acacia in the Byron Bay area near a beach and even though does not really look like Obtusifolia he is wondering if anyone knows what species it could be. The phyllodes are not as smooth as Longifolia but not as long and "corrugated" as the photos he has seen of Obtusifolia. He also noticed that the lower branches were dry and holding those curly dry thingies that he assumes were holding the seeds after flowering. He placed one in a photo if that could help identification.

Thanks to anyone replying :)

Hi Bushwalker77,
I'm in a similar area to you (just south of Coffs) and have been researching the local acacias for about a year now. The ones in your photos look like A.Sophorae, a sub-species of Longifolia (some scattered reports on active yield).
I've noticed that Obtusifolia tends to like a bit of altitude, so heading into the hills (and up the mountains) seems to be more rewarding. Some specifics to look for in the Obtuse (aside from white pipe-cleaner shaped flowers) are the blunt phyllode tip, irregular phyllode edge and red resinous margin. Bark is generally a greyish colour too. The 'curly dry thingies' are seed pods and Obtuse seed pods are similar to those Sophorae as they are more elongated (less curved-twisted, and thin) as say Longifolia. I find keeping a couple of file photos on my phone to make comparisons with when out in the bush helps heaps.
I'm sure your hunt has progressed somewhat since this post and love to know how you're going,
Flux
 
I dont know about acacia identification but I was just gonna suggest if you haven't yet, you should get some ehrlich reagent, do a mini-extraction with a small amount of the plant material and use the reagent on the resulting product.. if it changes to pink/purple color, thats a good sign there are tryptamines, so you can investigate the plant further.
