ABtES ENGELMANNI, A. EXCELSA. 69 



but less so than in A. Henziesii. Cones small, from 2 to 2£ 

 inches long." 



Habitat. — The slopes of the Rocky Mountains from New Mexico 

 to the head waters of the Columbia and Missouri Rivers, occupying 

 in Colorado a belt between the limits of 8,000 and 12,000 feet 

 elevation. 



Introduced into England in 1864. 



The foregoing particulars are taken from a description of the tree 

 by Dr. Engelmann, published in the Transactions of the Academy of 

 Science of Philadelphia, and reprinted in the Gardeners' Chronicle for 

 1863, p. 1,035. 



Since its introduction into Great Britain, Abies Engelmanni has proved 

 perfectly hardy. The young plants are distinct, having their branches 

 horizontal and stiff, very thickly covered, especially on the upper side, 

 with robust rigid sharply-pointed slightly-recurved leaves, more distinctly 

 quadrangular than those of any other American species. In colour, 

 the foliage is rather a deep green with much less glaucescence than 

 is seen in A. Menziesii, to which it appears to be nearly allied. 



The specific name was given by Dr. Parry, an American botanist, 

 in compliment to Dr. Engelniann, its discoverer, also a botanist and 

 physician of St. Louis, Missouri, U.S., and author of several valuable 

 papers on the North American Coniferse. 



Abies Engelmanni glauca differs from the type only in the 

 colour of its foliage, in which the natural green of the species is 

 merged by glaucescence into a bluish-grey. A strikingly beautiful 

 tree. 



This variety is the most ornamental of all the American Spruces; 

 its remarkable colour and regular outline render it one of the best 

 of Conifers for the lawn. 



Abies excelsa. — The common or Norway Spruce. Being more 

 frequently planted in this country for purposes of utility than for 

 ornament, its fine proportions are not often seen to advantage; 

 it is, however, under conditions favourable to its development, 

 one of the handsomest of Conifers for the decoration of the 

 park and landscape. When standing singly, and till it has reached 

 its maturity, its lofty trunk is feathered with branches from the 

 base to the summit, the lower ones decumbent by the weight of 

 their numerous branchlets, those higher up being horizontal, while
