From Categories: → Plants → Other Trees → Select a local species.. Click the: "? Can't Find It" [button] → Select a global species..
Then → Duboisia myoporoides
– there it is – again in other words from the NatureMapr categories of Plants > Other trees and then there in the global list of taxa.
May i suggest you set your own identification and i will delete my identification (i don't moderate North Coast NSW so can't confirm the ID – i do agree with your ID anyways ! ) .
