TWO NEW SPECIES OF EUCALYPTUS. 459: 
at 4,400 feet above sea-level, and known as Willow Gum. 
The species flowers in December. 
Seedlings—Hypocotyl erect, terete, red, glabrous, up to 
2°3 cm. long. 
Cotyledons obtusely quadrilateral to orbicular-reniform, 
entire, about 3 mm. long, 5 mm. broad, upperside green, 
underside red to reddish-green, glabrous; petiole about 3 
mm. long. 
Seedling foliage opposite, entire, glabrous, oblong- 
lanceolate to elliptical-lanceolate, petiole 1—2 mm. long; 
midrib prominent on underside, lateral veins fairly distinct, 
and arranged at angles of from 40—60 degrees with the 
midrib. On seedlings 5 inches high the second pair of leaves 
were elliptical-lanceolate, and up to 2 cm. long by 8 mm. 
broad, while the sixth pair were elliptical, and 2°5 cm. long 
by 1 cm. broad. 
This species is named in honour of the late Sir Thomas 
Livingstone Mitchell, Surveyor General, who collected 
many native plants, and was the second explorer to pass. 
Mount Buffalo. 
Affinities. 
1. With HE. vitrea R. T. Baker. From this it differs 
somewhat in its leaf venation, for the prominent, almost 
parallel veins of EK. vitrea are not represented in this new 
species. The pedicellate hemispherical fruits of E. vitrea 
are also different; the operculum of that species is shorter 
and more obtuse, while the peduncle is very much larger. 
The bark of the new species is smooth and white, that of 
EH. vitrea being fibrous over the greater part of the trunk, 
2. H. nitida Hook. f. From this it differs in its more 
globular fruits, pointed instead of obtuse buds, and is an 
umbrageous tree, while E. nitida is only a tall shrubby 
plant.
