CATALOGUE. 229 



leafy stem, 1^-2° high, simple or branched; leaves varying from linear to 

 oblong-lanceolate, 2-8" in width and 1^-4' long, with a long attenuate acu- 

 mination, strongly 3-nerved, the floral ones more or less dilated at base and 

 exceeding the flowers, which are either axillary along nearly the whole 

 length of the stem or clustered at the summit, where alone the tips of the 

 bracts are conspicuously colored. Only on stream-banks ; Truckee and 

 Ruby VaUies and in the East Humboldt Mountains, Nevada ; 4-6,500 feet 

 altitude ; July-September. (809.) 



Castilleia paevifloea. Bong. Gray, I. c, 336. Perennial ; pilose- 

 pubescent or hirsute nearly throughout, scarcely hispid ; leaves for the most 

 part 3-cleft or laciniately pinnate, the floral ones more or less dilated and 

 nearly always colored ; calyx deeply cleft both above and below, the seg- 

 ments either emarginately 2-lobed or deeply bifid with the lobes oblong or 

 linear ; lip of the corolla very short. — The most common and a rather vari- 

 able species ; stems 3-20' high, usually numerous, simple or branched ; 

 the lower leaves usually, and sometimes nearly all, entire and linear ; spike 

 usually short and dense, sometimes elongated ; the color of the floral leaves 

 varies from deep-red to flesh-color and yellow, rarely green ; the galea often 

 scarcely exceeds the calyx, or may be exserted 5-6". From Washington 

 Territory to Colorado, Arizona, (Ives,) and Southern California. Very fre- 

 quent on mountain slopes, from the Washoe Mountains to the Wahsatch ; 

 5-10,000 feet altitude ; April-August. (810.) 



Castilleia pallida, Kth. Vermont and New Hampshire, and 

 throughout British America from Labrador to the Great Bear Lake, and 

 Behring Strait; southward in the mountains to California, Northern 

 Arizona, and Colorado. Found from the Truckee to the East Humboldt 

 Mountains, Nevada, and in the Uintas and Wahsatch; 6-10,000 feet alti- 

 tude; June-September. The floral leaves in the specimens are mostly 

 entire, broadly oval and often rounded at the apex, not unfrequently conceal- 

 ing the flowers ; the galea varies much in length, scarcely exserted from the 

 calyx or 4-6" long ; bracts usually dull-scarlet rather than ochroleucous, 

 which color was met with only in Utah. It would not appear from these 

 specimens that any constant length of galea gives ground for a variety 

 miniata. (811.) 



Var. With the floral leaves narrower and lobed, the lower leaves 

 linear or lanceolate ; color ochroleucous or shades of red. Truckee Valley,
