 of great beauty. Native to British Columbia and New 

 Mexico, strictly pyramidal, very slow in growth. 



P. excelsa (Norway Spruce). A well-known

compact, broadly conical form with short branches 

 and foliage.

most fascinating of pygmy trees, low, irregular, cush- 

 iony in form, apparently tortured by ages of ele- 

 mental hardship. Brown branches and light green 

 foliage. Growth particularly lovely in spring. 



P. excelsa nana (Dwarf Norway Spruce). Very 

 dwarf form with dense horizontally spreading 

 branches.

The same characteristics as the Norway Spruce ex- 

 cept the branches are irregular and pendulous.

 lines on the upper surface. Very hardy. Requires
