One to few plants observed in single cluster in grassy patch of weedy River Red Gum floodplain woodland. Contextually, the plants are unlikely to have been dumped or rafted, and appear most likely to have established by seed (eg. bird-sown). Construction of a small residential subdivision on heights above occurred c. 2008-2010. The location remains relatively remote, but with adjacent disturbance from informal access as well as a nearby formal path that is as yet unconnected to regional networks.
