2* Taller. 

 S. Lyallii, Wats. Very finely puberulent or quite smooth : stems 

 numerous from a much branched matted base, leafy : leaves thin, nar- 

 rowly oblauceolate, acute, only 1— If inches long, 2 lines broad: inflo- 

 rescence considerably branched in the type : calyx varying with a^e 

 from subturbinate to inflated campanulate, 4 lines long: petals dark 

 purple, bifid with subentire lobes : anthers large, purple. — Proc. 

 Am. Acad. x. 342. — Cascade Mts., Lat. 49°, Lyall ; Sierra Co., Cal., 

 Lemmon ; Summit Camp, Cal., Kellogg. This doubtful species is to 

 be distinguished from some forms of & Douglasii only by its smaller 

 flowers, more leafy habit, and darker petals. All the specimens at 

 hand, including the type, are diseased and apparently sterile, the ova- 

 ries remaining undeveloped, and the anthers having been attacked by 

 a fungus ( Ustilago anther arum), to which their large size and dark 

 color are probably due. 



S. Douglasii, Hook. Finely pubescent, scarcely viscid : stems 

 very slender, usually decumbent and geniculate at the base : leaves 

 remote, long, linear to narrowly lance-linear, attenuate to each end, 

 spreading, 2-3 lines long, 1-2 lines wide : flowers borne mostly in 

 3-flowered, long-peduncled cymes : calyx oblong or obovate, rather nar- 

 row at the base ; the ends of the teeth surrounded by an ovate obtuse 

 inflexed membrane : petals white or pink, 2dobed ; segments obtuse ; 

 claw moderately auricled ; appendages oblong, obtuse : capsule nar- 

 rowly cylindrical, 5 lines long; teeth recurved ; stipe 1^ lines long. — 

 Fl. Bor.-Am. i. 88 ; Torr. & Gray, Fl. i. 190; Wats. Bot. King Exp.

 Cucuhalus Douglasii, Eat. Man., ed. 7, 266. — Wahsatch Mts., Utah 

 to Central California, northward to Montana and Brit. Columbia ; 

 June to September. A common and polymorphous species, of which 

 the following are the chief varieties ; all of them tending to intergrade 

 with the type, and separated from it and each other by no constant or 

 important floral character. 



Var. multicaulis. Grayish-tomentulose and less glandular : the 

 leaves more approximate, narrowly lanceolate or oblong, taper-pointed, 

 erect: stems more rigid. — S. multicaulis, Nutt. in Torr. & Gray, 

 Fl. i. 192. S. Drummondii, var. Torr. & Gray, Fl. i. 675. — 

 "Oregon," Nuttall ; Washington, Yakima Co., Brandegee (655 in 

 part); Klickitat, Howell; Spokane Co., Suhsdorf, Ramm ; N. Idaho, 

 Spalding, Sandberg (342) ; Montana, Scribner, Canby. 



Var. Macounii. Minutely pubescent, somewhat glandular above : 

 leaves distant, long and narrow, short-pointed, tapering very gradually
