I got a report from some Indian friends who got nothing from Nilotica. Again and again, it is the same old story, many of these species may contain tryptamines, but seasonally or just depending on the individual tree itself.
I went out walking yesterday in forest near Frankston, near Melbourne and would have seen what appears to maybe three variants of Longifolia. Some have light green, thin and pliable phyllodes, with little anastomisation, what is the strain I am used to seeing. Other trees have longer, thicker, dark green phyllodes, with a finer anastomisation. Others have shorter, Sophorae like phyllodes, but are darker green, and more leathery and the phyllodes have more evident anastomisation than Sophorae.
Unless, I am mistaken are there are three different species here (which I can't see what they would be), but they are all growing in the same area together as one big stand.
So I got some samples of the shorter, leathery green phyllodes, but bodged up the test!
I will need to go back and find out for sure about this species, as for Melbourne people it would be great to work it out and show them a relatively common tree they can just pick phyllodes from.
I have got 0.2% out of Longifolia, but it was from up north, and it came out as a powdery white crystal. The effect was quite light, but having a look at the tighter and finer anastomisation of these trees I found yesterday, I am more hopeful of a better result!
re: melanoxylon, my results are the same as Nen's, next to nothing from the bark.
The phyllodes keep speaking to me, but their taste is so awful, so you couldn't use it in a brew. Back in the day, you would always hear about "Black Wattle", which could be Melanoxylon or Mearnsii, which people in places like the Ottways, say their old mate is extracting from.
Thing is with Mearnsii as well, it appears there is an incredible amount of variation in this species. You can really see how little botanical classification work has been done on these bi-pinnate wattles and how much more needs to be done!
I think I have posted in here before about getting 1% clear crystal from Mearnsii around N.E. Victoria, not 10 kilometres from the EGA site! That was in April as I recall, but then I went back and tested the same tree in winter - nothing! Tested a lot of similar trees around April as well - nothing!
As for Longifolia var Sophorae, there have been reports of people extracting from this species and getting good yields, especially from around Melbourne, apparently the strain of which is a transplant from the South Coast of N.S.W.
