 seeds obovoid very acute at base, smooth or slightly areolated, less than a 

 line long ; coma at length reddish. * )regon to Alaska.

 low and slender stemmed, more or less cespitose plants, usually some- 

 what shreddy at base 



*>■ Leaves rather broad; flowers large, rose-purple; style shorter than 

 the petals. • 



E. rigidum HaussKn. Bot. Zeitschr, xxix, 51. Stems decumbent, 4-8 

 inches long, glabrous and rather glossy at base, glandular-pubescent 

 above : leaves 8-16 lines long, the upper more or less attenuate, lanceolate to 

 nearly obovate, acute, entire, cuneately narrowed into short winged petioles, 

 glabrous and very glaucous, firm wjth mosHy inconspicuous lateral veins: 

 lowers rather few in the axils of the reduced upper leaves which are often 

 adnate to the base of the peduncles; wvary more or less densely white 

 pubescent; calyx cleft nearly to the base; petals 7-10 lines long; stigma very 

 large, its surface jjilose-papillate ; seed smooth. Eastern base of the 

 Coast range, Josephine Co , Oregon. 



Var. canescens. Trel. Sp. Epilob.83. Densely velvety-canescent through- 

 out. With the type.

E. suffruticosnni Nutt T. & G. El. i, 488. Stems woody and intricately 

 much branched at base, a span high, minutely canescent throughout or at 

 length glabrate below: leaves numerous, less than 10 lines long, mainly 

 opposite, broadly lanceolate, acutish, entire, narrowed below but hardly 

 petioled, thick, with inconspicuous veins : flowers rather few, in the axils of 

 the scarcely reduced upper leaves ; calyx-tube broadly funnel-form ; petals 

 3-4 lines long ; capsule an inch long, short-stalked : seeds a line or more 

 long; coma long and very dingy. Oregon to northwest Montana and the 

 Yellowstone Park. 



* * Stigma more or less 4-cleft in the larger flowers, usually sub- 

 entire in the smaller; capsule prominently ribbed, rather short and 

 few-seeded ; seeds beakless, very broad and blunt, usually abruptly 

 contracted above the base, areolate or low-papillate ; coma pale, fall-

 glandular-pubescent above, and rather firm veinless leaves. 



E. paniculatum Nutt. 1. c. 490. Stems rather slender, 1-4 feet high, 

 loosely dichotomously branched, mostly white glabrate below : leaves 

 1-2 inches long, chiefly alternate and fascicled in the axils, lanceolate or 

 linear-lanceolate, often folded along the midrib, acute, rather sparingly 

 denticulate, tapering to a slender winged petiole, gradually passing into 

 the smaller bracts above : flowers rather remote towards the ends of the 

 ascending branches, erect : the bracts often carried up on the peduncle ;
