142 DWABF AND SLOW-GROWING CONIFERS 



P. Strobus, var. nana, of Beissner. 



May be either var. umbraculifera, Carr., or var. nana, 

 Hort. It is impossible to say which, for Beissner describes 

 another form under the name of var. umbraculifera. This 

 he distinguishes from his var. n^na by its unequal, shorter 

 leaves and smaller habit. But both var. umbraculifera, 

 Carr., and var. nana, Hort, have unequal leaves of similar 

 lengths. 



All that one can say with any certainty is that this 

 bunch of names covers at least three distinct forms — 

 namely: Vars. brevifolia, Loud.; nana, Hort; umbraculi- 

 fera, Carr.; and as the first cannot be traced in cultiva- 

 tion, I have nothing to add to Gordon's description of it 

 already quoted in full above. 



P. Strobus, var. radiata. 

 Syn. : var. nana, Hort. 



Buds. — Ovoid; acuminate apex; scales appressed; dark 

 brown; about | inch. 



Brancklets. — Annual growth about 2 inches; slender; 

 oak-brown; densely crowded; shght pubescence at base 

 of leaf-sheath. 



Leaves. — In fives, in dense tufts at ends of branchlets, 

 and also growing fairly thickly up the stem, all pointing 

 up or at right angles — not drooping. Irregular in length — 

 mostly about 3 inches, but usually some considerably 

 shorter on summit of tuft, and occasional whorls of minute 

 leaves — luider | inch — half-way down the branchlets. 

 Leaves three- sided, outer very dark green; two inner very 

 glaucous blue-white. Very slender, but stiffer than those 

 oivsLT. umbraculifera. Margins serrulate. Sharp-pointed. 

 This makes a roundish or globular shrub, very dense and 

 compact. I have a specimen about 4 feet by 4 feet. 



P. Strobus, var. umbraculifera, Carr. (" Conif .," ii. 400, 1 867). 

 Buds. — Ovoid; apex acuminate; scales appressed; 

 red-brown; about i^r inch.
