To recapitulate, these drawings illustrate the three groups — 



1. Longitudinales (0-25°). 



2. Obliquse (30-55°). 



3. Transversa- (50-90°). 



- leaking generally, the Transversa have the lateral veins closer to one another than is the case 

 of the other two groups. 



On the other hand, in the diagrams, the Longitudinales and the Obliquse and the Transversa are 

 sometimes shown, for clearness, with the veins further apart than they really are. 



The abruptness between the width of the lateral veins in Plate 245, fig. 2 (50°) and in fig. 3 (50-55°) ■ 

 is diagrammatic. 



The figures of E. maculata (50-55°), E.fieifolia (65-75°), E. corymbosa (80°) are fair average examples 

 of the width between the lateral veins in the Corymbosse. 



In the Transversa, although the lateral veins are usually closer together than in other sections, 

 they are further apart than shown in most of the diagrams of 50 to 90°. Thus, E. robusta, E. botryoides, 

 E. saliyna, E. resinifera, are referred to by most writers as being close to the Corymbosa, which include 

 most of the Transversa. Of these species I -how facsimiles of leaves in the " Eucalyptographia," and it 

 will be found thai E. robusta is 45-60°, E. botryoides 50-65°, E. salujna 50-70°, and E. resinifera 65-75°. 



The following species, which also do not belong to the Corymbosa, have also venation more or less 

 belonging to the e : — 



E. tetraptera, 30 50 ; /;'. propinqua, 50 ; E brachyandra, (•"> 55 ; E. Spenneriana, 45-50°; 



E. ten ellan . 55 60°.
