AFFINITIES. 



1. With E. odorata, Behr. 



Mueller (in " Eucalyptographia ") says E. odovata perhaps nearest approaches 

 to E. largiflorens {bicolor). 



This species runs into odorata, and in extreme forms I doubt if it is possible 

 to separate them. Usually the leaves of E. hicolor are dull-coloured, but this is not 

 an infallible guide. The fruits are usually smaller, sometimes much smaller, 

 and more cylindrical than those of E. odorata. The fruits of E. bicolor are sub- 

 cylindrical or ovoid, while those of odorata are more hemispherical. E. bicolor 

 has usually short filaments and blunt opercula. E. bicolor is usually found on flats 

 liable to floods ; E. odorata prefers drier situations. 



2. With E. hemiphloia, F.v.M. 



The likeness of E. bicolor to E. hemiphloia, F.v.M., var. microcarpa, Maiden, 

 when herbarium specimens are alone available, is often very striking and sometimes 

 deceived Mueller. The timbers at once separate them, that of E. hemiphloia being 

 pale and that of E. bicolor being red. The variety microcarpa has clean limbs, 

 while E. bicolor has rougher ; the former has erect branches, while those of the 

 latter are drooping or scrambling. The leaves of var. microcarpa are green, while 

 those of E. bicdlor are more glaucous, and with the intra-marginal vein further from 

 the edge. The fruits of var. microcarpa are often slightly angled at the calyx, and 

 less sessile. 



3. With E. microtheca, F.v.M. 



The habit, foliage, bark, and timber of the two species are often very 

 similar. The fruits are very difterent ; the valves of those of E. microtheca being 

 exserted. Both timbers are red, bvit where they grow together the timber of 

 E. microtheca is reputed less durable, softer and more faulty than that of E. bicidor. 

 The bark of E. bicolor usually covers the branches move than in the case of 

 E- microtheca.
