On this dry slope it is more likely to be implexa. It is difficult to tell the two species apart, except for flowering time (in Canberra around summer for implexa; around winter for melanoxylon) or if they are seeding ( pinky red fleshy appendage wrapped around the seed in melanoxylon and white appendage folded on itself at the base of the seed in implexa). Also melanoxylon is found usually im moist siteslike moist stream banks, implexa on dry sites.

Acacia melanoxylon is also found on high, dry sites around Canberra. It might be useful to compare bud development in Autumn and Spring The funicle colour can fade and if weathered it is hard to tell. I might get the identifications wrong but I think the leaf shape is different for the local species too.

The funicle colour may fade but there is a big difference in how it is arranged on the seed.

I will have to take more notice. There are still a few melanoxylon seeds around and I should be able to find implexa.

Mike, your images of the melanoxylon seed funicles (3343866, 4204113) are also very helpful.

It looks like Acacia melanoxylon to me. There are too many differences. The leaf shape especially is not normal for Acacia implexa. Both species occur in the area. I have an Acacia implexa growing in my back yard and it is nothing like this plant.

There don't seem to be any photos of A. implexa seed on CNM but Flora of the ACT gives a good description:
white funicle in few folds at one end - A. implexa
seeds encircled by double fold of bright red funicle - A. melanoxylon
white funicle in few folds at one end - A. implexa
seeds encircled by double fold of bright red funicle - A. melanoxylon

Sorry Betty
The seed in photo 4 looks like one from Acacia melanoxylon. I've cropped the photo to blow up the seed and added it back. Also see:

As well as my other work, I'm a moderator for Tuggeranong Hill.
