It was subsequently described by Bentham in B.Fl. iii, 228, and later 

 illustrated in the " Eucalyptographia " by Mueller, but the flowers and fruits arc 

 reduced in size in that work. 



The conical operculum is less in diameter than the winged and reddish 

 calyx-tube. 



The anther is long, shaded purple in colour (which is unusual), with a gland 

 at the top, and the crimson filament at the base.
