tip, shorter than the broadly ovate lobes: seeds lanceolate, acuminate, 

 wingless. On the highest mountains, Washington to California and the 

 Rocky Mountains. 



G. Parryi Engelm. Trans. Acad. St. Louis ii, 218, t. 10. Stems 

 numerous from the crown of a somewhat woody root, 10-15 inches high : 

 leaves glaucescent, thickish, ovate, varying to oblong-lanceolate, 9-18 lines 

 long, most of the pairs with somewhat sheathing base; the upper 2 or 3 

 pairs involucrate around the 1-5 flowers, concealing the calyx and some- 

 times almost equalling the bright blue corolla: lobes of the calyx small, 

 moderately or much shorter than the campanulate tube : appendages in 

 the sinuses of the corolla narrow, deeply 2-cleft, but little shorter than the 

 obovate lobes: seeds lanceolate, wingless, with obutse or ac itish edge. 

 Alpine and subalpine in the Cascade and Rocky Mountains. 



G. Gormaiii. Stems erect, 10-18 inches high : lowest leaves small, 

 with connate-sheathing base; the middle ones broadly ovate to nearly or- 

 bicular, with very short sheathing base, about an inch long, shorter than 

 the internodes, the uppermost one or two pairs cordate or subcordate and 

 involucrate around the usually solitary flower: calyx-lobes only 2, broadly 

 ovate, acute or acuminate, longer than the tube : corolla bright blue, an 

 inch long, nearly campanulate, its broadly *ovate lobes short-acuminate: 

 appendages in the sinuses very short, nearly entire: seeds oblong or lan- 

 ceolate, apiculate. Moist subalpine meadows, northeastern Washington 

 to Alaska. 



•*-•*- •*- Stems either tall gr low, many-leaved flowers not involu- 

 crate : style manifest. 



Corolla oblong-campanulate, with broadly, ovate lobes more or 

 less narrowed at base and the intervening plaits entire : calyx lobes usu- 

 ally from ovate to lanceolate, equalling or longer than the tube. 



G. MenziesiFGriseb. Gent. 191. "Stems afoot or less high slender : 

 leaves from narrowly oblong to lanceolate (inch and a half or less long), 

 somewhat 3-nerved : flowers one or two, short-peduncled or sessile: calyx 

 according to Grisebach spatbaceous and the lobes obsolete, in our speci- 

 mens with oblong-lanceolate foliaceous lobes (5 lines long) equalling the 

 turbinate-oblong tube : corolla an inch long ; its lobes 3 lines long and wide ; 

 its plaits truncate and obscurely -3-crenate : seeds ovate-lanceolate or ob- 

 long, barely acute or both ends obtuse. — Bogs, W. Oregon to Mendocino 

 Co., California." 



G. sceptrnm Griseb 1. c. Stems erect, 2-4 feet high, simple, or 

 short branched above, few to several-flowered : leaves ovate to oblong- 

 lanceolate indistinctly 3-7-nerved : calyx-lobes unequal, lanceolate to 

 ovate-oblong: corolla 1-2 inches long, its lobes nearly 4 lines long and 

 wide, its plaits truncate or with barely rounded entire summit: seeds nar- 

 rowly lanceolate with scarious acumination. Western Oregon to British 

 Columbia. 



G. Orfordii. Stems slender, 1-2 feet high, several from a thick per- 

 ennial root: leaves linear-lanceolate, 3 nerved, 1-3 inches long, below T re- 

 duced to connate-sheathing bracts : flowers on rather stout peduncles : 

 calyx- lobes linear-lanceolate, acuminate 5-6 lines long, longer than the 

 tube: corolla blue finely specked within, an inch or more long, its short 

 lobes acutish; appendages in the sinuses rounded: seeds minute cylindra- 

 ceous, not appendaged. Port Orford, Oregon, Oct. 1892 Joseph Howell. 



+* ++ Corolla funnelform, with ovate lobes not narrowed at base: the 

 plaits extended into conspicuous laciniate-toothed or cleft appenda- 

 ges : margins of the leaves scabrous: seeds surrounded by a distinct 

 and rather broad wing' ovate or oblong.
