134 ON THE EUCALYPTS OF N.S.W., PART VIII., 



moment, their bark immediately distinguishing them. The 

 smooth bark often of a yellow ochre or pale brown colour; hence 

 might be called " Brown-barked Gum." It is known in the 

 Mudgee district as "Slaty Gum," as well as "Black Box," both 

 descriptive names for certain trees.. The buds also are very 

 different, those of the variety of inmctata being ovoid,* and the 

 rim very sharp, with frequently a double operculum, those of the 

 variety of resinifera being conical and even rostrate. 



The fruits of the variety of resinifera have the valves more 

 exserted, and they sometimes have a tendency to be conical.

 in the colony from which we have obtained this species. Fruits 

 very large.

We will allude at length to this species in our remarks under 

 E. viminalis. We add some notes on E. Gunnii. 



Hooker, the author of the species, speaks of it (Fl. Tas. ) as 

 " a very common, but singularly variable small tree." No species 

 of Eucalyptus known to us is more variable; we will endeavour 

 to make clear some of the various forms it assumes. 



Considerable confusion has arisen in regard to E. Gunnii and 

 E. Stuartiana in early sendings from Australia and Tasmania, as 

 some forms in bud only are extremely difficult to discriminate. 



The confusion has even extended to viminalis (see remarks on 

 p. 137 a). 



There need be no further necessity for confusion if the 

 synonymy given in this paper (the outcome, in part, of personal 

 examinations of the Melbourne and principal European herbaria) 

 be noted. 



We would invite attention to a tree, "Hickory" (Lockhart 

 Morton), from Twofold Bay. " One of the largest trees of these
