 wood Canon and Heber Valley, 1905, Rydberg & Carlton 66^6 ;

Castilleja Vreelandii 



Perennial with a rootstock ; stem usually single, 6-8 dm. high, 

 glabrous or nearly so, shining ; leaves lanceolate, 3-5-ribbed, 

 glabrous or nearly so, 4—6 cm. long, somewhat acuminate ; bracts 

 lanceolate, usually 3-lobed with acute lobes, tipped with crimson ; 

 calyx 2-2.5 cm. long, tinged with crimson, equally cleft, viscid- 

 villous below, puberulent above, its lobes lanceolate, acute, 6-8 

 mm. long ; corolla dark-green with purplish margins ; galea about 

 2 cm. long ; lower lip 2 mm. long, with lanceolate teeth. 



This species is related to C. laiiceolata, but differs in the larger 

 flowers and the broader, almost glabrous leaves. It grows in the 

 mountains from Montana and Idaho to Wyoming and Utah. As 

 the type is regarded the following :

Castilleja purpurascens 



Perennial with a short caudex ; stems several, 1-3 dm. high, 

 glabrous or slightly puberulent, villous above, usually dark-purple ; 

 leaves narrowly linear, finely puberulent, 3—5 cm. long, 2—3 mm. 

 wide ; inflorescence short and dense ; bracts lanceolate, acute or 

 obtuse, the lower usually entire, the upper more or less cleft, 

 tipped with crimson ; calyx i 5—20 mm, long, more or less villous, 

 especially towards the base, equally cleft, its lobes 2-3 mm. long, 

 obtuse; corolla 2.5—3 cm. long, green with crimson margins; 

 galea about i cm. long ; lower lip 3 mm. long, with narrowly 

 lanceolate lobes. 



This is probably most closely related to C. Tweedyi and C. 

 ininiata, but differs in the lower habit, the darker coloration of 

 the bracts, the narrow leaves, obtuse calyx-lobes, and usually 

 purplish stem.
