RANGE. 



It is" found in Tasmania, and in the highlands of north-eastern Victoria and 

 south-eastern New South Wales. 



It is recorded from the following localities : — 



Tasmania. — The Hainilton-Ouse District (L. Rodway). 



Victoria. — Dargo High Plains (Dr. Heber Green). 



New South Wales.— Snowy Mountains, elevation of 5,000 feet (W. Baeuerlen); 

 Mount Kosciusko, on hill-sides, elevation of about 6,000 feet (J.H.M.). 



AFFINITIES. 



1. With E. coriacea A. Cunn. var. alpina. 



It is no doubt often passed over as a small E. coriacea A. Cunn., var. alpina, 

 but the perfoliate juvenile leaves and the venation of the mature leaves at once separate 

 them. E. coriacea has reniform anthers. 



2. With E. Gunnii Hook. f. 



This is the species with which E. Perriniana has so long been confused and with 

 which it has closest affinity. 



As regards the leaf base, we have various stages of (1) the auriculate, and (2) 

 amplexicaul, through the (3) connate to the (4) absolutely perfoliate. 



All four forms are seen in E. Perriniana, and the first two forms in E. Gunnii 

 Hook. f. It remains to be seen if the last two forms (3) and (4) do not occur in 

 E. Gunnii. So far I am not always able to separate specimens of E. Perriniana showing 

 only (1) and (2) from E. Gunnii, but the immature bud of E. Gunnii has a peculiarly 

 pointed operculum and the line of demarcation with the calyx-tube a raised rim. 

 The fruit of E. Perriniana appears to be smaller as a rule, and uniformly more 

 hemispherical, and the rim thinner than that of E. Gunnii. 



Figure 11, Plate 83 of my " Critical Revision of the genus Eucalyptus," exhibits 

 the perfoliate leaves of E. Perriniana and not E. cordata as stated. The record of the 

 locality should be near Hamilton, Tasmania. Mr. L. Rodway informs me he was with 

 the late Mr. R. D. Fitzgerald when he collected it.
