‘ 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. /anceolata, 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 15-20 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 1 cm. long; lower lip 3 mm. long, with narrowly 
lanceolate lobes. 
This is probably most closely related to C. Tweedyi and C. 
miniata, but differs in the lower habit, the darker coloration of 
the bracts, the narrow leaves, obtuse calyx-lobes, and usually 
purplish stem.
