Unfortunately PlantNET has not updated Platylobium formosum, which is now regarded as coastal only. Platylobium formosum does not occur in Victoria, so VicFlora only covers Platylobium montanum and Platylobium parviflorum. The article I used when checking the ID is: Thompson, I.R. (2011), A revision of Platylobium (Fabaceae: Bossiaeeae). Muelleria 29(2): 164-165
My ID was based on your ID of a similar plant in the same area: http://canberranaturemap.org/Community/Sightings/Details/3361806 . Should that also be P. monatum?
