The tree that I posted a few pics from here mis-labeled as longifolia has flowered so here's a few pics in case anyone has any ideas as to what it may be.

The flowers are not as pale as these pics indicate.

Hieronymous..what makes you certain it's not A. longifolia?..it fit's within the broad definition (unless i've missed something) ..incidentally many botanists believe var Sophorae should be a separate species (as it once was)
..

one of your pics re-attached below..fairly Longifoliaish to me..

Thanks, most factors seem to be suggesting it is floribunda.
It was a bushy tree perhaps 8ft tall and fairly wide. No basal glands and with the peculiar gap in the phyllodes as if its been purposelessly cut out or eaten by an insect.
Many thin anastomoses and roughly 4 prominent nerves as you can see on the photo.
Is it possible to plant this small branch for it to grow roots and grow into a tree?

Hi All,

I have snapped some pics of several Acacias today.

The first one appears to be A. floribunda except for the lack of flowers for which it is named. Almost all flowers were developed but they were very sparse on the tree. no basal gland, narrow phyllodes, creamy light lemon flowers. The whole tree was infested with galls so perhaps this is the cause of the lack of flowers or perhaps it is not floribunda. Interestingly the small branchlet with the flowers had different sized and shaped phyllodes than the rest of the tree.
Also interesting is that the galls all had hairs like on the branchlets and phyllodes.

The next photos are from the same tree and it represents 99% of what is on the tree. You can see how vastly different the phyllodes are from the previous photo with flowers.

The next ones i believe to be possibly A. mucronata spp. longifolia or floribunda but am not sure.
It has an abundance of rod flowers and the phyllodes are erect and running along the branch. Again no basal gland, rods, narrow long phyllodes.

This last one also required ID but again i am leaning towards A. mucronata or A. floribunda

Any help in whether i am correct or wrong on the above ID's will be greatly appreciated.

..Vitalstatistix..hi..the last one i'd say is A. mucronata.., the 2nd last probably floribunda or a cross between it and mucronata, as you theorise..
the 1st specimen (pics1-3), due to the flower shape, looks like it's in the A. acuminata/burkitti complex..pods would narrow this..

all great and interesting for research looking specimens..

Thanks nen I was starting think the same thing now it's flowered.

There were a few things that seemed out of place.
It was mainly the narrow phllyodes. The endemic longifolias in my area are a lot different to that one - broader phyllodes and a different growth habit, they also have much longer flower rods.

I know longafolias aren't very high in alkaloids but it might be worth investigating, it grows quicker than any Acacia I've ever seen.

Cheers mate
 
Hi all, I'm new here but was just wondering if anyone could tell me what kind of acacia this is and if it might contain any DMT or not. I found it on the banks of the river in Windsor, New South Wales. Any help would be greatly appreciated.

so i am now an acacian-in-training.
i found what i suspect is retinodes, it was found at sea-level (or close to it) unlike every other acacia found thus far.

is my suspicion of retinodes correct? (southwestern maui)

post #413 bit of a delayed response..but yes, A. retinodes..

Gday everyone was after some plants to be identified there is atleast 3 differnt types and was hoping for one of them to be acacia obtusifolia cuttings where taken in an area in nsw where the forsest has been logged an these plants where pushed into piles where the area has been cleared and where going to die i have not cut off living plants as i dont believe in doing it


these first images most resemble the a.obtus but the leaves look way to short compared to other photos

If its from Vic My book suggests a.longifolia due to its prominent 2 main veins and phyllode shape, also the flowers in spikes and the fact is in flower. Could do with a close up to see if theirs a gland near the base..
I am a newb at this hobby however so dont take my guess for gospel!
For keen amateurs I recommend the pocket series by Leon Costermans the'yre nice and portable with good descriptions and illustrations.
 
hey goinpiggen420 ... the ball flowered acacia you have there is acacia myrtifolia... a spermadine alkaloid called acacine was isolated from this plant. don't believe its been bioassayed (at least not formally) ...the second i'm not quite sure. coiled pods suggest could be maidenii? phyllodes don't look leathery enough to be longifolia though don't look quite the right shape for maidenii... perhaps it is a genetic variant of longifolia..anyone?

love the look of myrtifolia... the specimen i came across down in vic had slightly more lemon coloured flowers

aha nice name by the way
