130 DWABF AND SLOW-GBOWING CONIFEES 



between the pulvini; branchlets nearly all fasciated into 

 cockscombs. 



Leaves. — Mostly radial, pointing forward at acute angle; 

 about J to I inch long ; fine and thin, but stiff and sharp- 

 pointed. Light yellow-green with about three stomatic 

 lines on each side. 



A curious seedling form which I found, and now about 

 ten to twelve years old; a tiny bush, 7 by 5 J inches, and 

 incUned to make a perfectly shaped cockscomb-like head. 

 It is very distinct, every branchlet being fan or comb 

 shape. 



P. Schrenkiana, Fisch. 



Introduced in 1840 from West Central Asia — Thian- 

 Schan and Altai Mountains. It seems to be a geographical, 

 form of P. excelsa, differing from it chiefly in its domed 

 shape, brown buds, radial leaves, and smaller cones with 

 rounded scales. 



P. Schrenkiana, var. globosa, Schelle (Beiss., ii. 243). 



Beissner records in the Botanic Garden at Tiibingen a 

 compact globular form twenty-five years old, about 5 feet 

 in diameter. 



P. Sitchensis, Traut. 



Syn. : Abies Menziesii, Lindl. 

 The Sitka spruce of North-West America grows to 

 200 feet in its native habitat, and more than half that in 

 Europe (a tree in my own garden is 106 feet). The httle 

 plant hereunder described I found growing in good soil, 

 and so far it shows no sign of attempting to become 

 arborescent : 



P. Sitchensis, var. microphylla. 



Buds. — Minute — about xV inch; ovoid; scales ovate 

 and obtuse. 



Branches. — Few, ascending and irregular, bearing 

 branchlets in occasional crowded whorls.
