152 DWABF AND 8L0W-GB0WING CONIFERS 



P. Douglasi, var. dumosa, Carr. (" Conif .," ii. 258). 

 Syn. : var. Monstrosa, Beiss. (ii. 419). 



Raised by Andre Leroy, of Angers, France, and de- 

 scribed as an ugly, bushy, diffuse, monstrous form with 

 irregular thick branches, the branching irregular, declining 

 or nearly pendant, and very narrow, crowded, short, thin, 

 twisted leaves — some 4 to 6 mm. long, others at ends of 

 branchlets up to 20 mm., making a widespreading bush 

 not more than 2 metres high. 



This variety, which resembles a " witches' -broom," 

 remained dwarf, and at more than fifteen years of age was 

 about 4 feet in height. 



P. Douglasi, var. argentea compacta, Hans ex Beiss. (ii. 419). 



Described as a compact bush of beautiful silver-grey 



foliage; raised by Hans of Herrnhut from Colorado seed. 



P. Douglasi, var. pygmaea. 



Syn.: var. globosa, Sargt. ("Arnold Arboretum 

 BuUet.," No. 18, 1918), (not Beiss.). 



Buds. — About tV inch; cylindrical; pointed; Hght brown. 



Branchlets. — Glabrous; light brown; annual growth 

 I to f inch. 



Leaves. — Narrow — about ^V inch and from J to | inch 

 long; light yellow-green. 



This is the smallest form I have seen, and according to 

 Sargent it is one of the slowest-growing dwarf conifers in 

 the Arnold Arboretum Collection. It seems smaller and 

 more compact than either of Fletcher's dwarf forms. 



P. Douglasi, var. Fletcheri. 



Buds. — About J inch; narrow; ovate; pointed; red. 



Branchlets. — Annual growth about IJ inches; smooth; 

 shining; grey-brown; with occasional slight short scattered 

 pubescence. 



Leaves. — J to | inch; nearly radial; crowded; narrow; 

 soft; rather sharper pointed than the type; pale yellow- 

 green. Two stomatic bands beneath; not very white.
