yeah i got no idea if its obtus, but im pretty sure its not long or maid for these reasons not longifolia cause 1 it has a defined trunk, most longs have loads of branches round the bottom of the trunk. 2 the young phyllodes are very bright green with red tips, and older phyllodes very dark green and leathery, basically all long phyllodes are the same green, and not as hard and leathery. and 3 because the leaves are not separated in that nice equal fashion like longifolia is. the young leaves were smooth and laminated like, but the older dark green ones were very leathery and rough. it could be maidenii, but my only guesses as too why it wudnt be are 1 the bark was smooth, whereas most maidenii's are fissured, the phyllodes were not straight, and had red tips, both things maidenii's dont have, and again the phyllodes were leathery unike maidennii. oh, and the majority of the phyllodes have obtuse ends, whereas long and maid have pointy ones. im probly being a wishful thinker cause i want it to be obtus. if i knew more about obtus i could probably bring up a few reasons why its not obtus. ive read those ages loads of times, but seeing a real-life tree is what helps me the most. i dont wanna get my hopes up incase i fail. but i took a branch and got as much bark as i could from it (800g fresh) and did an extraction on it. it looks promising, but ill know in a few days. keep your fingers crossed
