To understand this species it is necessary to compare the explana- 
tions given under S. brachycarpa and S. desertorum. As I have 
already explained under S. glauca, the names S. glaucops and S. 
glauca villosa And. cannot be used for those forms which are 
named S. glaucops by Batt and also by RypBERG, who keeps

1906, he distinguished them in the key by the following charac- 
ters: “Leaf-blades oblong or linear-oblong; bracts obovate; shrub 
depressed,” S. pseudolapponum, and “‘leaf-blades oblanceolate 
or obovate-lanceolate; bracts oblong; shrub not depressed,”
