Picea amabilis, Loudon, Arb, Brit. iv. 2342 (in part), f . 2247, 



A tree, often two hundred and fifty feet in heightj or at high altitudes and in the north usually 

 not more than seventy or eighty feet tall, with a trunk from four to six feet in diameter, in thick forests 

 often naked for one hundred and fifty feet, or in open situations densely clothed to the ground with 

 comparatively short branches sweeping down in graceful curves and furnished with elongated lateral 

 pendulous hranchlets. Until the tree is about one hundred and fifty years old, when, in favorable 

 situations, it may be one hundred and twenty-five feet high, the bark of the trunk is thin, smooth, and 

 pale or silvery white, and on old trees it becomes near the ground from an inch and a half to two 

 inches and a half in thickness, and is irregularly divided into comparatively small plates covered with 

 small closely appressed reddish brown or reddish gray scales. The winter branch-buds are nearly 

 globose and from an eighth to a quarter of an inch in thickness, with closely imbricated dark lustrous 

 purple scales thickly coated with resin. The branchlets are stout, clothed for four or five years with 

 soft fine pubescence, light orange-brown during their first season, dark purple in their second, and 

 ultimately become reddish brown. The leaves are flat, deeply grooved, and very dark green and 

 lustrous on the upper surface and silvery white on the lower, with broad bands of about six rows of 

 stomata occupying the space between the prominent midrib and the recurved margins, resin ducts 

 close to the lower side and hypoderm cells forming an interrupted border under the epidermis on both 

 surfaces and on the edges ; on sterile branches they are obtuse and rounded and notched or occasion- 

 ally acute at the apex, from three quarters of an inch to an inch and a quarter in length, from one
