Tasmanian specimens are mostly from the seacoast, while Mt. 

 Victoria is an inland locality. In a paper"^ I have given very 

 definite evidence of the absolute similarity of many Tasmanian 

 and New South Wales plant forms, and this is an additional 

 example.

 L'Herit. var. alpina, Maiden (E. delegatensis, R. T. Baker). 



I propose to enquire into the position of a " Gum-top Stringy- 

 bark,"! called also, at least in New South Wales, "Mountain 

 Ash." 



The botanical names for it are synonyms.

The receipt of a large number of Gunn's specimens used by 

 Hooker in the preparation of the ' Flora Tasmaniee ' has enabled 

 me to clear up some hitherto doubtful points. 



E. gigantea, Hook, f., Lond. Journ. Bot. vi. 479, is " Stringy- 

 bark colonorum." It is in Fl. Tas. (i. 136) described in practi- 

 cally the same words, and it is called "Stringy-bark Gum." The 

 specimens quoted are Gunn 1095, 1104, 1106, 1965, 1966. 



In Part ii. (p. 59) of my "Critical Revision," under E. obliqua, I 

 have quoted the remarks of Hook.f. about Gunn's 1095 from Lake 

 St. Clair. The specimens labelled 1095 which have been seen by 

 me are, however, nearly typical obliqua from Lake St. Clair. It 

 will be observed that Hook. f. looked upon these specimens as a 

 variety of his E. gigantea.
