Coniferce Fitzroya. 443 



11. FITZRCYA. 



Evergreen trees with imbricated scale-like leaves. Flowers 

 monoecious. 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. Patagonica. 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. THtTJA. 



Evergreen trees or shrubs with compressed branchlets and 

 imbricated often tuberculate scale-like leaves. Flowers monoe- 

 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 Vitse, though the 

 Eastern species, or at least some of the forms, are usually known 

 in gardens under the name of Thuja. The principal difference 

 is in the scales of the fruit, which are shield-like and tubercled 

 in Biota, or the Chinese Arbor Vitse. The generic name is from 

 Ovov, an odoriferous tree used for incense. 



1. Th. gigdntea, syn. Th. Menziesii, and Th. Lobbii of English 

 gardens. This is a very ornamental fast-growing tree, attaining 

 a gre,at 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 Vitse. 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
