These three species were recorded for Queensland by Ferd. Mueller 
and F. M. Bailey but are unrepresented in herbaria by specimens actually 
collected in Queensland territory. Both these authors were in the habit 
of recording species that occurred in neighbouring States and which 
they considered must extend over the border and would sooner or later 
be found in Queensland territory.
