Botanical description. Species, E. Baueriana in Walpers' Repertorium ii, 924. 
Suppl. i (1843). 
The original Latin description will be found in Part XIII, p. 120, of the present 
work. 
It may be described in the following words : 
A tree of medium size with rough dark bark on the trunk and ultimate branchlets. With ;i 
rounded head of dense foliage. 
Juvenile leaves from nearly orbicular to broadly lanceolate in shape, dark green on both sides, 
thin, margin undulate, the intramarginal vein at a very considerable distance from the edge, 
venation almost triplinerved at the base, distant from each other, and spreading. 
Mature leaves ovate to nearly rhomboid-ovate, shortly acuminate, margins undulate, venation 
rather distant from the edge, subtriplinerved, venation spreading, rather thin in texture. 
Lamina 2-2J inches long, 1-2 broad, with a peduncle of 3-4 lines. 
Flowers five to seven in the axils of the leaves, the buds tapering gradually into the very short 
pedicels, the opercula conical and pointed, the anthers very broad, truncate, and sometimes 
so widely opened as to almost lose the appearance of pores terminally dehiscing. (Here we 
have evidence of transit between the Eucalypts with truncate anthers and the E. hemipMoia 
group of anthers.) 
Fruits conoid, often widened at the flat, thin rim, capsule sunk. 
Variety. 
Variety cornea Maiden (E. conica Deane and Maiden). 
This variety will be illustrated by a special plate in the next Part (LVIII). 
Intermediate forms between the normal form and its variety have been noted at the 
following places : 
1. Banks of the Lachlan (Cowra district); also Morongle Creek near Cowra. 
2. Tingha and Bolivia. 
3. Acacia Creek, Macpherson Range, and Wallangarra (both on the New South 
Wales-Queensland border). 
It will be more convenient to speak of the form and its variety when the variety 
has been illustrated and described.
