New isolated location of this potentially significant weed

User's notes

A single small plant, growing beside an animal footpad on the ridge south of Swamp Bog Creek, Naas valley, Namadgi NP. This plant has sticky seeds, so it is probably growing from a seed carried by an animal, because this new weed in Namadgi NP is currently mainly growing along the roadside (Naas valley fire trail) where it has been spread by vehicles. This plant destroyed.
