to Dr. Richardson, it is the most northerly tree that came under 

 his observation on the Coppermine River, within 20 miles of 

 the Arctic Sea, growing there 20 feet high. There are the fol-

Abies alba glauca, Plumbly, Mr. Dimsdale's Silver Spruce. 

 Syn. Abies alba argentea, Hort.

 Abies alba prostrata, Hort. 

 A dwarf bush, seldom growing more than 3 or 4 feet high, 

 but very dense, and with a very neat appearance. 



Abies alba minima, Knight, the Hedgehog-formed White

 Syn. Abies alba echinoformis, Hort. 

 Picea alba echinoformis, Carriere.

Syn. Pinus Alcockiana, Parlatore. 



, } bicolor, Maximowicz. 



Picea Alcockiana, Carriere. 



Leaves solitary, six lines long and half a line broad, curved
