..so a
quick overview of last few pages, for those who've been away a few weeks..
what we've seen mainly from mid-way p.24-26 is that, there being so many kinds of wattles, identification requires some practice..in both cases where negative results were reported from known
reliable species (
acuminata & floribunda) the plant tested was not the right species..
on p.26 we had a confirmed DMT result from A. floribunda S.E. Qld phyllode from Spice Sailor..and A. longissima (not so common) by Seldom..
..on
p24#468 i looked at
tars (amphoteric resins) which can cause extraction problems, as well as possible salt-form of acacia alkaloids;
p24#470 looked at some more
Asian acacias..
..on
p23 here is a Quick Guide For Newcomers to the thread, and some
African species..
INDEX OF THREAD here p.1 ..

..so, the good news is, firstly for
Growpen, that your photos at the bottom of p.26 ARE indeed almost certainly the 'typical variant' of
Acacia acuminata..it could be good to test the phyllodes and stem/branch bark (if you access any) independently, as the phyllodes of some acuminata's seem to have more ß-carbolines than the stem bark..if, after re-x the extract is still reddy/brown and not fully solid then it probably contains ß-carbs, like the phyllodes sent for testing to endlessness..this particular example (with tetrahydroharman etc.) had shorter and slightly more falcate phyllodes than those in your photos Growpen..looking very promising..
..and
bricklaya, good to hear of your enthusiastic further investigations..that latest tree you've posted photos of is really interesting

as it looks intermediate between A. floribunda and A. maidenii..the two are genetically related and could interbreed..without pods to see and fully developed flowers, i will say it's maybe floribunda..it does have forms like this with longer, larger phyllodes..floribunda is common in coastal regions, east of the dividing range..as
wira said back around
p.10 A. floribunda is commonly planted by councils, in parks or on roadsides in urban areas..
..&
Seldom, keep up the lateral thought..!
..so onwards researchers of the Acacia light..
and respect to the graceful trees..
