756 MISCELLANEOUS NOTES ON EUCALYPTUS, I., 



Hooker says, "in some varieties the young branches have a 

 fine glaucous bloom upon them . . . Lake St. Clair." While 

 Gunn's 1095 from that locality is non-glaucous, some of Gunn's 

 1100, collected by Hooker himself from Marlborough, (on the 

 Upper Derwent near Lake St. Clair) and which are E. radiata, 

 Hook, f . (non Sieb.) No. 4 (partim) are glaucous and are doubt- 

 less the specimens he had in mind. 



The loose branch of fruits of " E. giganteus^^ figured at fig. 4, 

 Plate 7, of Part 2, of my " Critical Revision," were depicted 

 from the same Kew herbarium sheet that contained the foliage- 

 specimens indicated, and are E. ohliqua var. alpina. 



Gunn's 1104 came from Black River, Circular Head, and is 

 typical E. ohliqua. 



Gunn's 1106 came from Sassafras Valle}^, and is typical E. 

 ohliqua. 



Gunn's 1965 and 1966 came from Arthur's Lakes and are my 

 variety alpina of E. ohliqua. In other words, they are E. radiata. 

 Hook, f., No. 4 (partim). They are doubtless the originals of 

 the drawing of Plate xxviii. of Hooker's Fl. Tas,! 



Of these four synonyms, therefore, E. gigantea, Hook, f., really 

 belongs to E. ohliqua, in spite of Hook. f. including two trees 

 under that name in F\. Tas. 



E. radiata, Hook, f., is founded on error, and the name should 

 be dropped. 



It is a question whether the "Stringybark Gum" or "Mountain 

 Ash" is a variety or a distinct species. Hooker, most Tasmanians 

 Avhom I have consulted, and I look upon it as a form of E. 

 ohliqua. Mr. Baker considers it to be a distinct species (E. 

 delegatensis). I am well acquainted with the tree in the field, 

 have a very large series of specimens, and I have an open mind 

 on the subject. It is probably a hybrid, E. ohliqua and E. 

 coriacea being the parents. 



The affinity of this form to E. Risdoni, Hook. f. var. elata, 

 Benth., is undoubtedly close, and Hooker's confusion of speci- 

 mens is readily accounted for. Indeed, at one time I held the 

 view that E. Risdoni, its var. elata, and my E. ohliqua var. aljnna
