46 A RESEARCH ON THE EUCALYPTS OF TASMANIA 



Remarks. This is now the first definite record of this 

 tree as a species in Tasmania. 



Hooker, in his " Flora Tasmania? " (1859), gives addi- 

 tional data to his original description of K. <jt<!<tf < / 

 (" Lond. Journ. of Bot." VI. 479. 1847)), and in this addi- 

 tional data he includes two other trees besides his original 

 "Stringy-bark" E. gigantea (K. obliqua). The one he 

 mentions under the name of " Stringy-bark Gum " (loc. 

 cit.) growing up to 4000 feet altitude is K. Ddegatensis. 



E. obliqua and K. regnunx grow intermixed at lower 

 elevations, and these are what Hooker evidently refers to 

 in " Flora Tasmania " : " Specimens have been felled 

 in the valleys at the base of Mt. Wellington." Hooker's 

 description of K. gigantea in his classical work must there- 

 fore be regarded as a composite one, and this is well 

 brought out by Maiden in his " Critical Revision of the 

 Genus Eucalyptus " (Vol. I., p. 58), under " K. obliqua," 



This species, K. Dclegatcntit, cannot be included under 

 E. gigantea, for that name belongs undoubtedly to K. 

 obliqua, as shown by the original description of Hookar 

 in his " London Journal of Botany " (1847), and later by 

 Bentham and Mueller. 



Hooker, in his introduction to the genus (" Fl. Tas."), 

 speaks "of a possibility of his having confounded two 

 species in that work the ' Swamp Gum ' and ' Stringy- 

 bark ' under that species." These two are now known 

 as K . rrgnans and K. obliqua respectively the original of 

 his description in " London Journal of Botany " will cer- 

 tainly not match E. Drlrgnh-nxis, for it is not f/i* 

 " Stringy-bark colonorum " as stated by him. 



Again, Hooker's remarks (" Fl. Tas."): "In some 

 varieties tin- //<>/i//t/ hranrln-x have a fine glaucous-pur /i! i 

 bloom in t/irff/, especially in Alpine localities; such is the 

 case with Mr. Gunn's No. 1095, from the banks of Lake 

 St. Clair, where it forms a forest on one side of the lake 

 only, to the exclusion of all other timbers "apply to this 

 species, and not his K . gigantea (E . obliqua), (" Lond. 

 Journ. Bot," 1847). 



The material was first collected for the museum by Mr. 

 C. F. Laseron in 1908, on Mt. Wellington, where it is ? 

 very common tree, occurring chiefly above 2500 feet. This 

 altitude is interesting, as in the original locality from 

 which the species was described Delegate Mt. it occurs 

 at an elevation between 4000 and 5000 feet. 



Mr. L. G. Irby, the museum collector, personally inter- 

 viewed Mr. Stephens, in order to ascertain exactly where
