Sections. 



Under E. tetraptera 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. tetraptera belongs. These 

 lithographs give readily an idea of the relative width, the distance of the dehiscence-lines and the curvature 

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

 connective ma.y be contrasted. In a similar manner hereafter sections of the Renantheraa, Heterostemones, 

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

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



(These promises were only carried out as below. J.H.M.) 



Mueller proceeds : ' Transverse sections of anthers of various Eucalypts. 

 (Series Normales, diametric augmentation, 28 times.)" Then follows a list of 

 fifty-eight species. 



Under E. populifolia, he says : — 



" The bye-following lithographic plate represents diagrams of anthers (after dehiscence) of many 

 Eucalypts pertaining to Bentham's series Renantherre, Heterostemones (Hemiantherse), Porantherse and 

 Micranthera?, in continuation of the transverse anther-sections (solely of the Parallelantherae) given with 

 E. tetraptera in the second decade. (Diametric augmentation .28 times.") ■ 



Then follows numbers 59 to 105. 



The value of these drawings is greatly diminished by the absence of any key 

 or descriptive matter, whatever. If the section is cut through the centre of the anthers, 

 it may not traverse the centre of the gland or connective. Nor do we know the 

 botanical history of the stamens employed. If a drawing is worthy of presentation, 

 it is worthy of ample description.
