For E. tessellaris, see Plate 156, Part XXXVIII. The juvenile leaves are narrow, 

 the flower buds clavate and decurved. The chief similarity is in the fruits, which 

 much resemble each other in size and outline, but they are otherwise very different. 

 One can readily crush the fruits of E. tessellaris between the fingers, as their walls are 

 papery like those of E. clavigera and its allies; those of E. trachyphloia are much more 

 strongly built. The trees are very dissimilar in appearance, E. tessellaris having tessel- 

 lated bark (and smooth upwards) as its name denotes, while that of E. trachyphloiahas 

 a flaky fibrous bark throughout, with a yellowish cast. 



4. With E. dichromophloia F.v.M. 



Its real systematic place should be next to E. dichromophloia, from which it can be distinguished in 

 rougher bark, in thinner less elongated leaves of a darker green above, and dull paleness beneath (therefore 

 not of equal colour on both sides), with recurved edge, in the want of stomata on the upper page of the 

 leaves, in the calyces of less polished smoothness, in smaller fruits with perhaps never or only rarely four 

 valves, and in the absence of any appendage to the fertile seeds. (" Eucalyptographia." under 

 E. trachyphloia.) 



For E. dichromophloia, see Plate 165, Part XL. Its affinity to E. trachyphloia is 

 not as close as Mueller thought it was. E. dichromophloia has a red timber, and a 

 reddish, flaky bark. The juvenile foliage of E. dichromophloia is described at Part 

 XLI, p. 3. 



The affinity of E. trachyphloia is with the Yellow Barks. E. eximia, peltata, 

 Watsoniana, and trachyphloia are Yellow-barks ; all have barks fibrous-flaky and more 

 or less yellow, and timbers palish in contrast to reddish, such as that of E. corymbosa. 

 These Yellow-barks are more stringy than those of the generality of those of the Blood- 

 woods (which are more flaky) ; in this respect they display affinity to 'the Peppermints 

 and even to the Stringybarks. The following table shows some of the characters 

 contrasted, so far as it is possible, to contrast species so closely related : — ■
