442 Conifera—L tbocedrus. 
10. LIBOCEDRUS. 
Handsome evergreen trees with imbricated scale-like leaves 
and moneecious flowers. Fruit oval, consisting of 4 leathery or 
ligneous valvate unequal scales. Seeds winged, 1 or 2 at the 
base of each scale. Species few, from New Zealand and South- 
Western and North-Western America. The name is from 
libanos, incense, and cedrus, the cedar, in allusion to the 
odoriferous wood. 
1. L. dectirrens, syn. Thiga Craigicna or Corrigiana and Th. 
guydntea of English gardens.—This is a very beautiful and dis- 
tinct evergreen tree of compact erect habit, with a remarkably 
stout trunk. It is generally known under the latter name, but 
unless this genus be merged in Thija, this is its proper position, 
on account of the difference in its fruit from that of the true 
Arbor-Vites. The branchlets are numerous, alternate, and 
plaited, or flattened laterally. Leaves bright rich glossy green, 
small linear and seale-like, quadrifariously imbricated, acute at 
the free apex, with long decurrent base, persistent and clungated 
on the older branches. The glandless decurrent leaves and 
columnar habit readily distinguish this from all its allies. 
Fruit ovate or oblong, erect, smooth. Seales furnished with a 
small recurved prickle just below the apex. A native of the 
Sierra Nevada Mountains of California, where it attains a height 
of 120 to 140 feet. 
2. L. Chilénsis.—-A handsome tree, growing 60 to 80 feet 
high in its native country. Branches compressed, spreading 
and pendulous. Leaves oblong-trigonous, appressed, obtuse, 
glaucous green. Fruit ovate, composed of four woody scales. 
This ornamental specics is a native of the Andes of Chili, and 
rather tender in this country. 
3. DL. tetrdyona.—tThis is also a South American species, 
extending from Valdivia to Magellan’s Straits, and ranging 
“according to locality from a dwarf bush to a lofty tree 120 feet 
or more in height. With us it is a shrub of compact pyramidal 
growth, with spreading depressed branches. Branchlets tetra- 
vonal, densely clothed with small ovate scale-like obtuse pale 
ercen leaves, imbricated in four rows. Fruit consisting of 6 
coriaceous scales in three pairs. This is a somewhat hardier 
species than the last. 
L. Doniana is an exceedingly beautiful species from New 
Zealand, but it will not bear our Winters.
