The population in this area appears to consist wholly of plants with hairy phyllodes. This is a rarely seen occurrence for A. aculeatissima (see VicFlora entry). I've checked other NatureShare records and hairy phyllodes occur only in the northern Pyrete but not in surrounding areas (eg. Brisbane Range, Riddells Creek, Whittlesea, Kilmore, Blackwood - all of which have glabrous phyllodes).
New species record for this collection. Found in the area burnt in last year's January wildfire. Large sheathing bracteole visible in second pic. As a result of this observation and analysis of herbarium samples, the VicFlora entry was updated to include "Leaves (with) margins, at least toward base, usually with irregularly spaced, small tooth-like outgrowths."
New species record for this collection. Found in the area burnt in last year's January wildfire. This record is possibly an example of cleistogamy or apomixis in this species, with many plants flowering at this time too.
