 PLATE 245. 



Obi i quo? (concluded). 

 Fig. 1. 45-60°. E. botryoides (1st Ed., Plate 3; 2nd Ed.. Plate 6, " Research, &c"). See also " Eucalypto- 

 graphia " leaf. 

 Also Macrantherse, Angophoroidese, Corymbosa?. 



2. 50°. Macrantherse, Corymbosse. 



3. 50-55°. E. maculata, Wyong, N.S.W., the lateral veins in this member of the Corymbosse closer 



together than the preceding. 



4. 50-65°. E. botryoides ( ;c Eucalyptographia"). Also Macrantherse. Corymbosa?. (See also fig. 1.) 



5. 50-70°. E. saligna (' Eucalyptographia "). Also Macrantherse, Corymbosse. 



6. 60°. See E. longifolia (1st Ed.. Plate 6, '"' Research, &c"), with the lateral veins further apart 



than shown in fig. 



7. 65-75°. E.ficifolia (fresh leaf). 



PLATE 246. 



Transversa (concluded). 

 Fig. 1. 65-75°. E. resinifera ('' Eucalyptographia,"). 



2. 75°. E. corymbosa (1st Ed., Plate 2; 2nd Ed., Plate 5, " Research, &c"). 



3. 80°. E. corymbosa (fresh leaf). 



4. 85°. E. corymbosa. The most transverse leaf of this species, that could be found. 



[In the diagrams, the middle third of each leaf is alone shown, for the reason referred to at 

 Part LVII, p. 394.] 



To recapitulate, these drawings illustrate the three groups — 



1. Longitudinales (0-25°). 



2. Obliqiue (30-55°). 



3. Transversa? (50-90°). 



Speaking 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.ficifolia (65-75°), E. corymbosa (80°) are fair average examples 

 of the width between the lateral veins in the Corymbosa?. 



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

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

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



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

 belonging to the Transversa? : — 



E. tetrapiera, 30-50°; E. propinqua, 50°; E. brachyandra, 45-55°; E. Spenceriana, 45-50°: 



E. tessellaris, 55-60°. 

 E. punctata and E. Shiressii may be added to this list, and perhaps others. 



Sometimes the transverse venation of a juvenile leaf (e.g., E. acmenioides, fig. 5a, Plate 42), with 

 lateral veins 45-55°, simulates that of the Corymbosse. It belongs to the Renantherse. 



Here I may insert a reminder to read Part XVII, pp. 392 to 408. Thus Longitudinales, p. 394; 

 Obliquye, p. 398; Transversa?, p. 406. The narrowing of a leaf causing a tendency to greater acuteness of 

 the lateral veins, p. 394.
