bicbiro Posted August 22, 2016 Hello, Just wondering if any knowledgeable person could give an id for these two Acacia's. I am interested purely from a knowledge perspective. Thanks for any help in advance. Greg Share this post Link to post Share on other sites
0 communacacian Posted August 22, 2016 Hi Greg, second one looks like acacia acuminata standard or broad phyllode variant, first one unsure, not familiar with the area but im keen to head over there to see all the trees soon! Share this post Link to post Share on other sites
0 cristop Posted August 22, 2016 (edited) The first could be Acacia extensa, but it looks very large for that species. I agree that the second is A. acuminata. I'm thinking you must be somewhere along the eastern edge of the Jarrah forest rather than in the Perth area..

0 bicbiro Posted August 22, 2016 (edited) thanks for your responses. I appreciated it. These are taken on the darling scarp/eastern hills, (exact location not announced for obvious reasons) A friend is adamant the first one is an Acacia acuminata, but i can't find any information that shows the flowers having such a short sessile. I did note the two barks have a similar pattern. Is this any indication? Might be a dum question, but do all A. acuminata variants have curved tips on there phyllodes (Because on the macro level, the first species does not)? Thanks again for your input. Greg.

0 cristop Posted August 23, 2016 I actually found some of the first acacia on a walk by the Canning River today and grabbed some material together with last year's pods from the litter. It is Acacia dentifera. I took it through the electronic key ('Wattle') and confirmed it against written descriptions of certain features. Here is some basic info: https://florabase.dpaw.wa.gov.au/browse/profile/3294 If you submit photos in future try to find pods. With large plants there are usually some old ones in the litter. Also include something in the photos to help with scale (matchbox, pen whatever). All A. acuminata variants have curved phyllode tips and those tips are hairy - at least a little bit. The hairs might run down the margins of the phyllode or they may be restricted to the tip. There are a few other acacias that also have hairy curved tips (e.g. A. assimilis, A. aulacophylla) but these are not flat in cross section like A. acuminata. The other A. acuminata variants, including A. burkittii which is now a species in its own right, are only found in the arid zone. A. longifolia is a weed and you'd be doing the environment a favor if you killed these trees. Not so with A. acuminata. 1 Share this post Link to post Share on other sites
0 bicbiro Posted August 23, 2016 Thanks Cristop. I went back to the site and could not find any pods at all, but good advice. I did get a sample and took a photo of the second acacia for scale. any suggestions what the second acacia is? Share this post Link to post Share on other sites
