Contfere—Fitzroya. 443 
ll. FITZROYA. 
Evergreen trees with imbricated scale-like leaves, Flowers 
moneecious. Fruit small, consisting of 9 scales in three whorls, 
the upper and lower of which are barren, and the intermediate 
one has 2 or 3 winged seeds at the base of each scale. This 
genus was dedicated to Captain FitzRoy, who was the first to 
discover the following species. 
1. F. Patagoénica.—A large tree 100 feet high, or smaller, 
according to the elevation at which it grows. Branches 
slender, spreading, and incurved at the extremities. Leaves 
small, ovate-oblong, flat, obtuse, sessile, in 2, 3 or 4 rows. 
The only species hitherto described, native of the mountains of 
Patagonia, and not sufficiently hardy to withstand our coldest 
Winters. 
12. THUIJA. 
Evergreen trees or shrubs with compressed branchlets and 
imbricated often tuberculate scale-like leaves. Flowers monce- 
cious. Fruit conoid, composed of overlapping scales affixed 
by the base, and destitute of recurved prickles. Seeds usually 
2, with a marginal wing, As thus characterised, this genus is 
limited to the American species of Arbor Vite, though the 
Eastern species, or at least some of the forms, are usually known 
in gardens under the name of Thija. The principal difference 
is in the scales of the fruit, which are shield-like and tubercled 
in Bidta, or the Chinese Arbor Vite. The generic name is from 
Ovov, an odoriferous tree used for incense. 
1. Th. gigantea, syn. Th. Menziésiz, and Th. Lobbit of English 
gardens. This is a very ornamental fast-growing tree, attaining 
a great size in the valleys of the Rocky Mountains. Branchlets 
slender, flexible, and very numerous, compressed, covered with 
scale-like finely pointed leaves, which are of a very bright 
shining green on the upper side of the branches and glaucous 
on the lower side. Leaves destitute of tubercles, persistent 
and changing to brown on the older branches, Fruit almost 
exactly like that of the common American Arbor Vite. This 
is perfectly hardy and greatly exceeds the following species in 
elegance and gracefulness of habit. 
There is so much confusion in the nomenclature of Conifers 
and many of them have so many synonyms, that we do not feel 
quite confident that we have adopted the correct name for the
