Acacia Obtusifolia? ID help please

[kindness]

There a bunch of these on a property I know.  Are they obtusi’s?  Would love some feedback.  Plants are located close to where distribution map shows there to be some.  North western Wollemi npTIA

Thanks boss.  Was pretty sure they were.  Some fantastic plants out here!  Huge!  Heaps of old fallen and recently fallen trees.  Landowner also clearing fire trails snaps saplings so spoilt for choice.  
 

was reading recently they mainly press by suckering too which I didn’t know.

 

thanks for your input freakosystem

Shit!  Where did everyone go?  This place is quiet now!  Must be getting old.  I’m pretty sure they are obtusis anyway.... it’s just been a while and I hadn’t found them as big as they are here before .

[wachumacallit]

"Obtusifolia" = obtuse + foliage = blunt-leaved.

To my (inexpert) eyes, the tips of these phyllodes look rather sharp. And long -- A. longifolia?

Keep an eye out for flowers and seed pods, for a positive ID.

Not flowering.  I believe longofolia are flowering now.  Obtusi’s flower dec - feb.  Also Phyllodes are tough to the feel not soft like I believe longifolia are....

 

here’s some more photos... this one is like the ones I used to find I.e very young

Old seed pods

[Freakosystem]

Yes, they are all Acacia obtusifolia.

[teamwhy]

Obtusifolia can grow heaps big. maybe 15 to 20 meters

[kindness]

Yeah, wow! I’d only really found the younger ones that seem to have the thicker wider phyllodes, (to around 2m in coastal hinterland - thousands In regrowth where fkn loggers had been thru). Certainly some old examples here, I’d guess at around 4metres. Quite a bit of the forest hasn’t been logged here so mainly prolific around riparian areas, edges of the forest etc.  

 

These are also toward the extent of Obtusi’s western range and are obviously frost hardy, temps here getting down to -5 in winter.

 

Thanks for your input teamwhy

I don't know if this helps but this was grown from A. Obtusifolia seeds a bought from SAB

[kindness]

Certainly does JR.  I’ve got my eye in now.  Such diverse qualities to the plant.  From the deep dark green thru to almost purple brown then the reds and yellows... all the same type of plant’s phyllodes.  Beautiful!  
 

Your plant is certainly benefiting from a lot of love and water.  Lovely looking plant ❤️

*typo from ego hahahaha to plant!

One of the identifying features that may help you differentiate from the many lookalikes (esp when not flowering) is the reddish leaf margin when held up to the light, which you can see really well in @rottenjonny's 3rd photo. 

Nicely done!

[Strontium Dawg]

Run your finger along the margins of obtusifolia phyllodes. You'll feel a characteristic rough, almost serrated edge in comparison to longifolia which will be smooth as a baby's proverbial.

And yes, you can often see a red crusty outline on them.

[gerbil]

kindness' ones are obtusifolia, rottenjonny yours is a maidenii.
