120 DWABF AND SLOW-GROWING CONIFERS 



P. excelsa, var. diffusa. 



Buds. — Very small — under \ inch; conical, acute; dark 

 crimson-brown. 



Branchlets. — Very crowded and overlapping, pointing 

 out and forward at a narrow angle ; orange-brown ; annual 

 growth J to 1 inch ; thin and flexible ; pulvini and grooves 

 sUghtly marked. 



Leaves. — Pectinate: those below pointing down and 

 slightly forward; those above appressed and pointing 

 directly forward ; upper side of branchlets and buds almost 

 concealed by leaves. Leaves soft, thin, flexible ; i to | inch ; 

 sUghtly incurved, uniform, flattish, light yellow - green ; 

 tapering sUghtly to both ends. 



A form akin to var. pumila, but distinct enough to be 

 separated from it. Grown as var. diffusa at Kew, where it 

 has made a dense, close-growing, but widespreading bush, 

 18 inches by 4 feet. 



P. excelsa, var. Sargenti. 



Syn. : var. ivana, Hort. aHq. 



Buds. — Small, conical; red-brown, shghtly resinous; 

 about tV inch. 



Branchlets. — Fine and very crowded; pointing forward 

 at angle of 45 degrees. Shining pale yellow. Annual 

 growth 1 inch. 



Leaves. — Arranged irregularly. Pectinate or radial, in 

 latter case few beneath. All point forward and out at 

 same angle as branchlets. Rather thin, but round; small 

 — A inch, and uniform; apex abrupt, blunt, and soft. 

 In winter the leaves occasionally become tipped with 

 yellow. 



This form was sent to me by Professor C. S. Sargent, and 

 is one of two forms grown at the Arnold Arboretum under 

 the name of var. nana. From the specimen branches 

 sent to me, its f oKage appears very distinct, and I cannot 

 identify it with the description of any recorded form.
