446 GENTIANACEAE gentiana 



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, 318, t. 10. Stems nu- 

 merous 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 3 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 S-cleft, but little shorter than 

 the obovate lobes : seeds lanceolate, wingless, with obtuse or acutish edge. 

 Alpine and subalpine in the Cascade and Rocky Mountains. 



G. Gormani. 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 3, 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 lanceo- 

 late, apiculate. Moist subalpine meadows, northeastern Washington to 

 Alaska. 



■^ ■^- -I- Stems either tall or 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 usually, 

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

 G. Menziesii Griseb. Gent. 191. "Stems a foot 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 spathaceous 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 oblong, barely acute or both ends obtuse. Bogs, W. Oregon to Men- 

 docino Co., California." 



G. sceptrum 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 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 cylin- 

 draceous, 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 append- 

 ages : margins of the leaves scabrous : seeds surrounded by a dis- 

 tinct and rather broad wing ovate or oblong.
