Eucalypti generis species novae. I. 53 
and an entirely smooth white bark. Juvenile leaves lanceolate, sym- 
metrical, tapering to a very short petiole and to a fine-pointed apex. 
Equally green on both sides. Strictly opposite; penniveined, the lateral 
veins very fine and anastomosing, the principal lateral veins making an 
angle of about forty-five degrees to the midrib. Entirely glabrous, and 
the twigs reddish and terete. 
The opposite-leaved character is retained for a considerable period, 
the leaves becoming thicker, narrower and longer. | have leaves, still 
in the opposite stage, 3 inches long and Le inch wide. In this stage 
the foliage resembles that of E. amygdalina (particulary the type Tas- 
manian form) or of E. linearis a good deal. It is seen to have a trans- 
lucent margin and to be full of oil dots, emitting a peppermint odour 
when crushed in the warm hand, Mature leaves up to 6 inches 
long and !/, inch broad, tapering very graduaily into a fine apex. At 
the base it tapers less gradually into a petiole of perhaps 1 inch. Tex- 
ture thickish, the midrib alone conspicuous. Buds nearly ovoid when 
ripe, with a hemispherical or slightly pointed operculum. Calyx tapering 
into a short pedicel which may be absent. Peduncle may be !/, inch. 
Usually three to seven in a head. Flowers opening in longitudinal 
parallel cells. Fruits smooth, usually barely */,, inch in diameter, sub- 
cylindrical, rim rather prominent, domed, the valves (indifferently 3 or 4) 
moderately well exserted. Bark very smooth and white. Timber pale- 
coloured, fissile, probably of no specical merit. 
Hab. — On the tops of the highest hills (cirea 4000 ft.) in fissures 
of granite rocks around Wallangarra, occurring on both sides of the 
New South Wales-Queensland border (J. L. Boorman; July 1904). 
Affinities. — This tree belongs to the viminalis-Gunnii series. From 
E. Gunnü and its forms it is separated by the broadish juvenile leaves 
of the latter. At the same time some specimens of var. maculosa of the 
latter have juvenile leaves intermediate in width. From E viminalis it 
is separated by its uniformly multi-flowered character, the absence of 
ribbons on the bark, the narrower juvenile foliage and other characters. 
Its nearest affinity appears to be E. Smith R. T. Baker, from which 
it appears to be sharply separated by the markedly smooth bark of the 
new species. I separate the two trees mainly on that ground, the bark 
of E. Smithii being almost an lronbark. The timber also of E. Smithü 
appears to be darker.

Juvenile leaves not seen in the youngest stage, but seen when 
still opposite. Medium lanceolate and acuminate, 4—5 inches long and 
1'/, broad, with petiole of 1/, inch. The midrib often pink. Intramarginal 
vein at some distance from the edge, the lateral veins roughly parallel 
and forming part of a delicate anastomosing arrangement. Texture thin: 
margin undulate. | have seen no sign of glaucousness so far. Twigs
