ABIES 19 



although many of them were sent out, not as var. nana, 

 but as var. Hudsonica. Of seven specimens in my 

 possession obtained from different sources, I note only one 

 that appears to be in any way distinct ; this I received as 

 var. globosa nana; it is making a thicker, rounder head, and 

 its leaves are slightly darker above; but underneath, its 

 leaves, like those of every other specimen I have seen, are 

 blue-white like those of A, balsamea. Since writing this, 

 I have received further confirmation from Messrs. Den 

 Ouden and Sons, of Boskoop, who have grown these forms 

 for many years. They say: " We also cannot see any 

 difiPerence between nana globosa and Hudsonica. Over 

 twenty years ago we used to get Abies Hudsonica from 

 Belgium, and it was quite distinct. Unfortunately we no 

 longer have it." 



The following description is taken from specimens in 

 gardens received under both names. Buds, small, globose ; 

 shiny red, resinous. Branchlets: annual growth about 

 I inch, smooth grey-yellow; small scattered pubescence. 

 Leaves pectinately arranged in about three ranks at right 

 angles to branchlet; flat; curved J to J inch, usually 

 wider from centre to apex ; upper side, shiny dark green, 

 grooved and slightly convex; under side, raised green 

 midrib separating two blue -white sunken stomatic 

 bands. Resin canal marginal. A small spreading shrub, 

 rarely 2 feet high; branches very numerous, forming a 

 compact, tight, rather fiattish head. Carriere records 

 a specimen planted at Chateau Balene in 1838. Twenty 

 years later it was 15 inches high and 5 feet diameter. 



A. balsamea, var. prostrata, Carr. (i. 218). 



Syn. : Picea balsamea, var. prostrata, Knight (" Syn. 

 Conif.," 39, 1850). 



A very low-growing dwarf form with numerous wide- 

 spreading, scattered branches, otherwise like var. Hiid- 

 sonica. Professor Sargent ( ' ' Arnold Arboretum Bulletins, ' ' 

 18, 1918) says that near the timber line of the White Moun-
