times attaining a height of 120 or even 140 feet ; and a 

 trunk of 7 feet in diameter is not uncommon. It rises 

 from 80 to 100 feet without a limb. "This tree much 

 resembles Callitris quadrivalvis in its foliage. It has 

 probably been confounded with TJuija gigantea, of 

 Nuttall, from which, however, it can be distinguished by 

 the folia ore alone; the long, decurrent bases of the leaves

being characteristics of the Libocedrus." Dr. Bigelow 

 says : " This tree is only to be found at an elevation of 

 some four or five thousand feet above the level of the sea, 

 in the Sierra Nevada Mountains of California." 



Although very beautiful in appearance, we are afraid to 

 recommend it for general cultivation, notwithstanding it 

 does well on our grounds in a suitable border. The leader, 

 and occasionally the side shoots, are injured during the 

 winter on account of the late succulent growths which 

 this species is liable to make, and which is the bane of 

 these rapid-growing, half-hardy Conifers. To cultivate it 

 successfully, a slow growth should be encouraged, and the 

 soil must always be well drained. Our own specimen 

 fruited freely the past season, and we were thereby enabled 

 to prove its distinct character. 



3. L. Doniana, Endllcher. Syn. Thuja Doniana, 

 Hooker. Leaves small, adpressed, imbricated in four 

 rows, acute, light glaucous or pale green color. Branches 

 ascending and incurved, with numerous, compressed 

 branchlets. Cones small, obovate or ovate, terminal, and 

 solitary; with 4 ligneous scales in opposite pairs, each 

 producing a solitary, winged seed. 



From the northern portion of New Zealand, where it 

 attains a medium height, and occasionally forms a large- 

 sized tree. This rather new species greatly resembles our 

 Arbor Vitres ; but, being of recent introduction, we cannot 

 speak of its hardiness in this country, especially in the 

 Northern States. At the South, we judge it could be ac- 

 climated, but with us its hardiness is questionable. In
