36 Rydberg: Rocky Mountain flora 



purple, glabrous or short-villous in the inflorescence ; leaves nar- 

 rowly linear, 2-6 cm. long, i -3 mm. wide, glabrous or the lower 

 sparingly white-villous ; bracts brownish, 1-2 cm. long, 3-cleft 

 with lanceolate lobes, white-villous with short hairs; calyx 12—15 

 mm. long, deeply cleft below, less deeply so above, its lobes lance- 

 olate, about I mm. long; corolla 2.5-3 cm. long, at last strongly 

 curved, greenish with yellow margins; galea 12—15 nim. long; 

 lip about 3 mm. long, with linear-lanceolate lobes. 



This species is related to C. cognata and C. linariaefolia. 

 From the former it differs in the color of the bracts, different 

 pubescence and the more arching corolla, from the latter in the 

 color of the bracts, the lower habit and the smaller corolla. It 

 grows in meadow land with alkaline soil.

Castilleja magna 



Perennial ; stem a meter or so high, glabrous and shining, 

 angled; leaves lanceolate, 4-6 cm. long, glabrous, 5 -ribbed and 

 reticulate, more or less acuminate ; inflorescence short and dense ; 

 bracts ovate, entire, tipped with crimson, as well as the axis of the 

 inflorescence viscid-ciliate ; calyx about 2.5 cm. long, cleft half- 

 way down both above and below, its lobes lanceolate, acuminate, 

 4-5 mm. long ; corolla 4-5 cm. long, greenish, tinged with 

 crimson and with crimson margins ; galea fully 2 cm. long ; lip 

 about 3 mm. long, its lobes lanceolate. 



This species somewhat resembles C. rhexifolia, but is a taller 

 plant, with smaller bracts and much larger corolla. The latter is 

 of about the size of that of C. Siiksdorjii, \wh\.ch. however is a much 

 smaller and more pubescent plant and has narrow leaves.
