larly cymose: peduncles terminal or rarely and tardily somewhat lat- 

 eral ; pedicels elongated, unequal, erect; the lowest often more or less 

 distinctly axillary : sepals oblong-lanceolate : capsule exceeding the 

 calyx, acutish, dark and shining ; seeds very smooth. — Edinb. Phil.

 James, Cat. 181. — A variable species marked by its long dark- 

 colored acutish capsule and very smooth seeds. It is widely distributed 

 from Maine to Arctic America, and from Alaska (Siberia) southward 

 along the Rocky Mountains to Colorado and on the Pacific slope to 

 San Bernardino, Parish. The commoner form has acute sepals and 

 leaves varying imperceptibly from flaccid and spreading to erect and 

 somewhat pungent. (Var. fi of Torr. & Gray, Fl. i. 185. S. stricta, 

 Richardson, etc.) The typical form with spreading leaves and " very 

 obtuse " sepals is comparatively rare. The following, although the 

 best marked varieties, are connected by innumerable puzzling inter- 

 mediate forms. 



Var. lseta, Wats. Low, smooth or somewhat pubescent, 1-4 

 inches in height, usually very glaucous, densely leafy at the base : 

 leaves carinate, lanceolate-subulate to linear, rather rigid, erect, 2-6 

 lines long, shorter than in the type, narrower than in the following. —

 Hook. 1. c. i. 96. S. longipes, var. 8, Torr. & Gray, Fl. i. 185.— 

 Arctic America to the Rocky Mountains of Montana and Wyoming 

 to Gaspe, Allen. (Siberia.) A very similar form has been found on 

 the coast of New Brunswick, Fowler. The variety peduncularis of 

 Fenzl is a boreal form somewhat intermediate between this variety 

 and the next, and indefinitely characterized by still more elongated 

 pedicels. 



Var. Edwardsii, Wats. Low, smooth or pubescent : leaves 

 lanceolate to ovatedanceolate or even ovate, shorter than in the type : 

 stems usually but 2-3-flowered ; the lower peduncles axillary, much 

 longer than the others. — Bibl. Index, 113. S. Edwardsii, R. Br.
