4. With E. saligna 8m. 



E. resinifera " is allied in the fruit and foliage to E. saligna, differing chiefly in 

 the pedicellate flowers and large operculum " (B.F1. iii, 246). The plates of E. saligna 

 (Plates 99 and 100) Part XXIII can be referred to. The buds of E. saligna have usually- 

 shorter opercula and they are often sessile. The fruits of E. saligna have a thin rim, 

 and the finger-nail can be passed between it and the valves. 



E. saligna is a smooth-barked, straight tree of gullies ; E. resinifera is a fibrous- 

 barked tree of drier situations, shorter in the trunk, and with a larger head. 



5. With E. Stuartiana F.v.M. 



E. resinifera is allied " in the fruit to E. Stuartiana, from which it is readily 

 distinguished by the venation of the leaves as well as by the operculum." (B.F1. iii, 

 246.) 



The plates of E. Stuartiana (Plates 101 and 102, Part XXIV) can be referred 

 to. The juvenile leaves of that species are sessile or stem-clasping, and almost circular, 

 the opercula are short, often hemispherical ; the fruit is less domed. 



E. Stuartiana occurs at higher elevations and not in the coast districts, which 

 E. resinifera frequents. E. Stuartiana has a sub-fibrous white bark like a shorn sheep; 

 that of E. resinifera is very different. E. Stuartiana has a pale-coloured weak, non- 

 durable timber, the antithesis of E. resinifera in these respects. 



6. With E. tereticornis Sm. 



See Bentham's remarks, quoted under E. siderophloia var. rostrata. 



It has already been hinted (p. 208) that in the operculum E. resinifera and 

 E. tereticornis may resemble each other a good deal, but their relations will be better 

 understood when E. tereticornis is dealt with in Part XXXI. 



E. tereticornis is a somewhat erect smooth-barked species; E. resiniiera has a 

 mors spreading head, and is fibrous-barked. The timber of E. tereticornis is more 

 interlocked.
