Rydberg : Rocky Mountain flora 39 



white hairs ; leaves 1.5-3 cm. long, 3-5-cleft at the middle, densely 

 glandular-puberulent, the body lanceolate, 3-ribbed, the lobes 

 narrowly lanceolate and directed forward ; bract similar to the 

 leaves, tipped with crimson or scarlet ; calyx equally deeply cleft 

 above and below, 18-20 mm. long, its lobes lanceolate, 5 mm. 

 long, acuminate or acute ; corolla about 2.5 cm. long, dark-green, 

 with crimson margin ; galea about i cm. long ; lip 3 mm. long, its 

 lobes lanceolate. 



This species is related to C. Jiispida, C. Bradbiiryi and C. 

 rnpicola. From the first two it differs in the lower habit and 

 viscid or glandular pubescence, and from the last one in the shorter 

 galea. It grows in the mountains among rocks at an altitude of 

 2700-3300 m.

Castilleja ampliflora 



Perennial, cespitose and somewhat woody at the base ; stems 

 3—4 dm. high, usually branched, ascending, puberulent and some- 

 what villous ; most of the leaves entire, lanceolate, 2—3 cm. long 

 with a short and rather dense pubescence; the upper 3— 5-lobed, 

 the middle lobe being broad and the lateral ones small ; bracts 

 3-lobed with a broad rounded middle lobe, crimson, i — 1.5 cm. 

 long; calyx 1.5—2 cm. long, villous, equally cleft above and 

 below, its lobes 3—4 mm. long ; corolla nearly 3 cm. long, more 

 turgid than usual; galea fully 1.5 cm. long; lip 3 mm. long, with 

 lanceolate lobes. 



This is perhaps most closely related to C. Bradtwyi, but the 

 stems are more branched, the corolla more turgid, the leaves more 

 Inclined to be entire, and the galea fully as long as the corolla-tube. 

 It grows at an altitude of 1 150-1350 m.

 entire, toothed or 3-cleft, rose or brownish, puberulent, villous-
