This species is characterized b}' its brick-red bracts and calyx. 

 Grows in big clumps in meadows, up to an altitude of 2000 m. 



Montana: Wolf Creek, July 24, 1897, Rydberg & Bessey, 4.^6^. 



* Castilleja sulphurea. 



Perennial, with a short more or less branched caudex ; stem 3-5 

 dm. high, striate, finely puberulent or the upper portion slightly vil- 

 lous, simple ; leaves lanceolate or the upper ovate, 4-5 cm. long, 

 entire, acute, finely puberulent, 3-5-ribbed, light green ; bracts 2-3 

 cm. long, broadly ovate, obtuse, entire, or with a few small teeth on 

 the side above the middle, 3— 5-ribbed, puberulent, light yellow with 

 a greenish base : calyx about 1.5 cm. long, about equally cleft before 

 and behind and cleft about 2-3 mm. at the sides; corolla greenish, 

 tinged with red, 2.2-2.5 ^^^- ^o'^g' the galea about three times as long 

 as the lip which is deeply 3-cleft. 



In color and general habit it most resembles C. hitea Heller, but 

 differs in the form of the leaves and bracts and in the pubescence. 

 C. lutea is densely villous, its leaves are cleft into linear-lanceolate 

 segments and its bracts are more or less lobed or cleft. The leaf-form 

 is that of C. rhexifolia, described above, from which it is easily dis- 

 tinguished by the color of the bracts and the form of the corolla. 

 Grows on wooded hillsides, at an altitude of about 2000 m.

 broader. The pubescence is villous.
