Timber. —A moderately hard, close-grained timber, full of shakes and gum 
veins, and apparently of little economic value. It possesses few of the good 
qualities of E amygdalina, Labill., which is fissile, soft, and easily worked. 
Size. —A medium-sized forest tree. 
Habitat. —Apparently commonest in New South Wales, hut also found in 
Victoria and South Australia. I expect to find it in Tasmania. It is a species 
which requires further investigation, as it is rather unstable. 
Victoria. 
Hills near Mansfield (Strathbogie). 
South Australia. 
“Shrub about 4 feet high, bark ash grey. In Stringybark Forest, 15 miles N.W. of Mt. Gambicr, 
S.A.” (Collector ?)■ 
The venation is not quite so straight as the type originally figured by 
Mr. Baker, but it appears to be closer to E. vitrea than to any other species. I 
have some specimens of E. vitrea from the locality whence the type was gathered 
with even more spreading veins than this particular specimen. 
New South Wales. 
As regards this State, it is apparently confined to the southern mountain 
ranges and spurs of the Blue Mountains. Specific localities are Crookwell, 
Bungendore, Marulan, Wingello, Sutton Forest (Moss Vale), Bullio to Wombeyan 
(18 miles from the latter place), Ilampton-Oberon Road (near Jenolan Caves). 
Departures from the type which one expects to find in a hybrid are :— 
(a) Jenolan Caves, with very narrow leaves. 
(b) Delegate. Broad leaves. 
( c) Berrima, with a preponderance of E. coriacea blood.
