v2 EUCALYPTS CULTIVATED IN THE UNITED STATES. 
In the Southwest it has made a fairly rapid growth, but does not give 
promise of reaching a great size. The trees are inclined to be tall 
and slender, with little foliage near the ground. (Pl. XXXV.) The 
bark of the lower part of the trunk is dark gray, rough, and partially 
persistent, but from most of the trunk it flakes off in patches. The 
bark of the branches is smooth and light colored. The twigs are often 
conspicuously angled. The leaves are scattered, nearly lance-shaped, 
and about the same color on each side. The flowers are of medium 
size, in clusters of 4 to 16, on scattered stalks. The flower-bud cover- 
ings are conical. The seed cases are nearly spherical, or the shape of 
the broad part of an egg. The round form, resembling that of a pill, 
suggested the specific name p7lularis. 
Climatic requirements.—The Blackbutt grows along the coast of 
southeastern Australia, and to some extent on inland mountain slopes. 
In America it grows quite thriftily at and near the coast, but does 
not thrive in the dry, hot interior valleys, enduring neither very high 
nor very low temperatures. 
Uses.—The strong and durable timber of the Blackbutt is used in 
Australia for house carpentry, for bridge and ship building, for tele- 
graph poles, and for railway ties. Its slender growth makes it espe- 
cially suitable for telegraph poles. It is considered one of the best 
all around timbers furnished by any Eucalypt. Fence posts of this 
timber are reported to last twenty years. The tree is an excellent 
honey producer, the honey from it being reported to be of an especially 
good quality. 
_ Eucalyptus piperita. 
WHITE STRINGY-BARK. 
Characteristics. —The trees of this species attain a considerable 
height and are commonly erect and quite shapely. The grayish bark 
of the trunk is fibrous and persistent. The leaves of the adult trees 
vary in shape from a broadly lance-shaped and very unequally sided 
to a narrowly lance-shaped and quite straight leaf. The young seed- 
lings are clothed with distinct hairs. The flowers are of about medium 
size, in compact clusters of 6 to 12. The flower-bud coverings are 
cone-shaped or taper-pointed. The seed cases are the shape of the 
broader part of an egg or are nearly spherical. 
Climatic requirements.—This tree makes a fairly rapid growth near 
the coast and in cool inland situations, but does not endure dry, hot 
climates, and will not tolerate heavy frosts. 
Uses.—The timber is readily split and is used for fencing and gen- 
eral building purposes. It is one of the species eligible for planting 
for a forest cover on mountain sides where it is not too dry nor sub- 
ject to too heavy frosts.
