1>. Cusickii Greene 1. c. More or less pubescent and glandular: leaves 

 broadly to narrowly lanceolate, entire, or dentate toward the apex, usually 

 obtuse, 1-2 inches long, narrowed below to a winged petiole : scapes 3-4 

 inches high, few-flowered: bracts of the involucre narrowly lanceolate, 1-2 

 lines long: lobes of the calyx lanceolate, acute, but little longer than the 

 tube : corolla- lobes dark purple with yellow base and a dark purple line 

 at the mouth of the tube: stamen tube less than a line long, almost black : 

 anthers yellow with a black stripe through the centre : capsule ovoid, acute, 

 scarcely surpassing the calyx, 5-valved from the apex. Dry hillsides, eas-

 rounded at apex, glabrous, rather thick, smooth, entire, narrowed at base 

 to a winged petiole an inch or less long; flowers purple, about 5 lines wide, 

 lobes orbicular or nearly so, notched, with a very short claw 2 lines long, 

 tube exceeding the calyx by 2 lines; funnelform above the calyx; calyx- 

 lobes 1% lines long and subulate lanceolate, barely acute, equalling the 

 tube of the calyx ;jpod nearly spherical; pedicels of the lateral flowers about 

 a line long, the terminal one 2 to 6 lines long; bracts oblong to ovate lan- 

 ceolate, entire or toothed at apex, 1 to 6 lines long ; base of plant covered 

 with the dead sheaths of former leaves. Marshy places at Ketchum Idaho. " 



Var. minor Jones 1. c. " Leaves an inch long or less, elliptical ob-
