Under E. telraptera in " Eucalyptographia " Mueller writes : — 



! ' The bye following lithographic plate presents transverse anther-sections of many Eucalypts 

 pertaining to Bentham's series Normales (Parallelantherse) to which also E. tetra/ptera belongs. These 

 lithographs give readily an idea of the relative width, the distance of the dehiscencc-lincs and the curvature 

 of the valves peculiar to the anthers of the various species: and thus at a glance the size and form of tho 

 connective may be contrasted. In a similar manner hereafter sections of the Rcnanthcraj, Heterostemoncs, 

 Poranthcne and Micrantherse will be provided, to be followed by full drawings of the anthers of many 

 different species of aD the series, side by side."
