OMG pinnaCLE - you were 100% correct with your original suggestion. I have never before seen Five Minute Grass this dense, lush, lanky and beautiful; it's gob-smacking! I've collected a herbarium specimen (RWP 11952) because I suspect most material from the ACT has a much smaller stature. Michaelb: note that the correct name for Tripogon loliiformis is now Tripogonella loliiformis (see https://biodiversity.org.au/nsl/services/search?product=APC&tree.id=51209179&name=Tripogon+loliiformis&inc._scientific=&inc.scientific=on&inc._cultivar=&max=100&display=apc&search=true.
