in grassy woodland, approx 2 m tall; first photo shows fruits and leaves; I don't know this species; there is a range of non local Australian species growing in the reserve nearby which are recruits from Federal Highway plantings.
Natureguy, I think your id is correct - I think it is the same specimen that Max recorded before and Tapirlord id-d as M. parvistaminea. The ACT Census of Vascular plants lists the species as Exotic Australian; ALA records not necessarily reflect natural occurrence; see for instance ALA records of Acacia baileyana.
