8 HARDY CONIFEROUS TREES. 



are likewise more in keeping with those of that species. 

 Though otherwise an interesting cross, the hybrid boasts no 

 striking distinction as an ornamental tree. 



A. Cilicica, Carriere. {^Synonym: — Pinus cilicica^Y^x\2L- 

 tore.) Cilician Taurus. — Though not generally hardy in this 

 country, yet the appearance of specimens that I have seen in 

 widely different localities, causes the tree to be included here. 

 It is much after the style of the common silver fir, but both 

 branches and foliage are more slender and usually less plenti- 

 fully produced. The leaves vary in length, according to their 

 position on the branches, being shortest above, and largest 

 and usually curved on the under sides. Not generally to be 

 recommended. 



A. COncoBor, Lindley and Gordon. Colorado White 

 Fir. (^Synonyms : — Pinus concolor, Parlatore; Picea concolor 

 Murray ; P. lasiocarpa, of gardens.) Colorado, Utah, and Ari- 

 zona. 1 85 1. — Although much confusion has existed between 

 this and other allied species, yet the present conifer is easily 

 distinguished by the irregular leaf arrangement, and by the 

 upper and under sides of these being nearly the same colour 

 — hence the specific name concolor^ of similar or like colour. 

 The leaves vary according to position from 2 to 2\ inches in 

 length, are of a greyish-white hue, changing as they grow old 

 to a soft, pale green. The cones, which are usually produced 

 singly, are about 4 inches long, and the seeds larger and 

 weightier than those of the nearly allied A. grandis. 



As an ornamental tree, the present species must be con- 

 sidered as a decided acquisition, the general outline being 

 symmetrical, but without the accompanying stiffness which so 

 readily distinguishes several members of this family. The 

 spread of branches in young and healthy trees being wide 

 in proportion to the height, warns intending planters that 

 sufficient space should be given for perfect development. In 

 fairly exposed situations it would seem to thrive best, and, 

 considering that on low-lying ground it has suffered from 

 frost in spring, the elevated positions are to be recommended.
