It accords well with the description of the species given in the " Eucalyptographia," hence I need 

 not refer to it further here, more especially as I shall have to draw attention to it in distinguishing the 

 varieties. 



The typical form grows from near sea-level to at least 4,000 feet, as on some small streams rising in 

 Mount Livingstone. It is especially found following the river courses, and ascends to its highest elevation 

 without extending to the hills on either side. (See PL 15, Figs. 23 to 31; PI. 14, Figs. 7, 8, 9.) 



Size.— Mueller (" Eucalyptographia ") quotes a Victorian tree up to 320 feet 

 high and with a diameter of 17 feet, and another of 20 feet, but in view of the 

 shrinkage which has taken place in the reputed heights of E. regnans from the same 

 districts, when taken in hand by a surveyor, I recommend that authoritative 

 measurements be sought for. At the same time tbe species attains a very great 

 height; I have personally seen enormous trees. 



Bark. — Rodway, speaking of Tasmania, where the type came from, says (" The 

 Tasmanian Flora," p. 57), " Bark usually smooth and white from the base, but 

 sometimes the trunk coarsely scaly or scaly-fibrous even to the upper branches." 



With a rough persistent bark, at least on the trunk and main branches, that of the smaller branches 

 often smooth and deciduous, and sometimes the whole described as deciduous. ... In New South 

 Wales specimens the bark sometimes said to be quite smooth, probably when the rough bark has been 

 shed. (B.F1. iii. 239, 240.) 



Bark much persistent on the stem and sometimes also on the main branches, outside rather dark- 

 coloured, wrinkled and rough, comparatively solid in texture, though somewhat fragile; through secession 

 leaving the younger bark outside smooth and whitish-grey or almost white, giving off externally wheji 

 rubbed, a flour-like bloom, as does also the bark of E. redunca. (Eucalyptographia.) 



The late C. Walter speaks of " A coast form with rough bark, Port Phillip." 



In New South Wales, most generally the bark is smooth, deciduous, hanging in 

 strips. It is what we know as a Ribbony Gum." The ribbons are best seen on 

 wet, windy days; they then flatten out and are seen to be of great length, like 

 streamers or pennants. 



Notes on the anatomy of the bark of this species by Professor Moeller of 

 Vienna, will be seen in the " Eucalyptographia." 



Seedling leaves.— Usually they are narrow, but they vary a great deal in size 

 and texture,- becoming almost coriaceous in some specimens. As regards the breadth 

 of seedling leaves, we take a few instances almost at random. 



(a) Narrow and broadish; multiflowered. (A. W. Howitt, Wando Vale, Vic.) 



(b) Broadish; in threes. (Sunny Corner, N.S.W., J. L. Boorman.) 



(c) The broadening of the seedling foliage is very common in northern New South 



Wales, and Mr. L. Rodway informs us that broadish seedling leaves are 

 common in Tasmania in this species also. 



Broadish juvenile leaves are figured at Fig. 3a, Plate 118, and Figs, la, lb, lc, 

 2, 11a, lib, Plate 119.
