PRINCIPAL SPECIES OF EUCALYPTS GROWN IN AMERICA. 53 
Eucalyptus botryoides. 
BastaARD MAHOGANY. 
Characteristics.—The tree reaches a fairly large size (75 to 150 feet 
high when fully grown), making a vigorous growth when young. 
(Pl. XI.) It is consequently a handsome tree during the early years 
of its growth, and when fully grown is very stately in appearance. 
(Pl. XII.) The bark of the stem of the young tree is quite smooth, but 
that of the lower part of the trunk of the adult trees is rough, com- 
monly persistent, and of a dark-gray or brownish color. The bark of 
the branches and of the young trees flakes off, leaving a smooth 
ereenish or yellowish surface. The leaves are horizontally placed and 
are rather large and thick, having a dark-green, shiny upper surface, 
with a much paler under surface, the veins spreading like the parts of 
afeather. The flowers are stemless, above medium in size, in close 
clusters of 4 to 10, on rather stout, flattened stalks. The seed cases 
are cup-shaped or goblet-shaped, of rather large size, in compact 
clusters. (See Pl. LI.) 
Climatic requirements.—This species thrives in a coast region, but 
is not suited to regions having a dry climate. In Australia it seems 
to prefer moist, sandy situations close to the seacoast, and, according 
to Baron von Mueller, will thrive in a soil containing stagnant water. 
In California it grows successfully in quite a variety of situations within 
50 miles of the coast, having been quite extensively planted about 
Santa Barbara and Montecito, where it does well. 
Uses.—This tree is one that can be used as a forest cover for low- 
lands in moderately humid regions where heavy frosts do not occur. 
On account of the nature of the foliage it is useful as a shade tree 
in many situations. The timber is called *‘swamp mahogany” and 
‘*bastard mahogany” in Australia, where the colonists of different 
sections hold it in differing degrees of esteem. Mr. Maiden thinks the 
latter may be due to a confusion of names. Mr. Bailey and Baron 
von Mueller both report the timber to be valuable, while Mr. Maiden 
speaks of it as ‘‘an inferior hard wood, both on the score of strength 
and durability.” Baron von Mueller and Mr. Bailey report the timber 
as tough, hard, and durable, useful for beams in large buildings, knees 
of boats, for posts, for the parts of wagons, and for shingles. The 
wood is of a reddish color and close-grained. Baron von Mueller 
states that posts formed of it are very lasting, no decay having been 
observed after fourteen years of use. 
Eucalyptus calophylla. 
Characteristics.—This is a moderate-sized tree, differing considera- 
bly in appearance from most other Eucalypts. (Pl. XIII.) The bark 
is rough, and grayish or brownish in color. The broad leaves are
