Taking the word " longitudinal " in its ordinary meaning, I do not think it can 

 be fairly used to indicate angles of more than 25 degrees. It will be observed that some 

 leaves, while including the maximum of 25, may go beyond this figure, and thus pass over 

 into another section (Obliquae). 



As it is impossible to follow the measurements of angles without diagrams, Miss 

 Plockton has drawn a number of leaves, with the middle third drawn to scale, showing 

 all the angles referred to in the text that the secondary veins make with the midrib. 

 I regret that it is not possible to reproduce them in the present Part, as that would 

 be most convenient, but they will be reproduced in an early Part (LX). 



The measurements about to be and already quoted have been made by one of 

 my botanical assistants (Mr. R. H. Anderson, B.Sc, Agr.) : I have not altered a figure. 

 But I impress on my readers that they are only approximations. 



In the following lists Coriacese indicates a group of the Renantherse, which 

 includes E. coriacea, and closely-related species. Renantherse indicates all other species 

 of the Renantherse. The terms Cornutse, Corymbosse, and Eudesmiese are self- 

 explanatory. The Angophoroidese indicate those species with papery fruits, as in 

 Angophora. These terms will be further explained when the grand classification of 

 the species is arrived at. 



The majority of species having longitudinal venation belong to the Renantherse 

 (winch includes the Coriacese) in the smaller angles. These are mostly Gums, 

 Peppermints, Stringybarks. In addition we have belonging to groups other than the 

 Porantherae, Gums, Mallees, Boxes.
