fore and behind, the lobes short-bifid: corolla barely exceeding calyx and 

 bracts; galea short, not more than half as long as the tube, twice as long 

 as the lip ; lip slightly ventricose but not callous, the 3 teeth short-oblong, ob- 

 tuse, as long as the ventricose portion. Northwestern Wyoming and ad- 

 jacent Idaho and Montana. 



20. Castilleja pallescens (Gray) Greenman, Bot. Gaz. 25: 266. 1898. 

 Cinereous-puberulent ; stems 2-3 dm. high, usually several from a woody 

 perennial base, simple or sparingly branched above: leaves 3-parted into 

 linear lobes, or the lower entire : bracts similar to the leaves, with dilated base 

 or the upper with shorter, obscurely whitish or yellowish lobes: calyx deeply 

 2 r cleft, the broad lobes merely 2-cleft at the summit: corolla over 12 mm. 

 long; galea broadish, obtuse; the lower lip nearly half as long as the galea, 

 obscurely saccate. Northwestern Wyoming to Oregon and Washington. 



21. Castilleja lineata Greene, Pitt. 4: 151. 1900. Tufted stems rigid and 

 brittle, but not suffrutescent, about 2-4 dm. high from a perennial root, 

 narrowly and not densely spicate; herbage hoary-tomentose : leaves ascending, 

 linear, 3-6 cm. long, entire, or in more robust plants with one or more pairs of 

 linear segments, all strongly 3-nerved and channeled and appearing striate: 

 bracts similar to the leaves, more commonly palmately cleft to the middle into 

 3 linear lobes: corollas greenish and inconspicuous, little exceeding the calyx 

 and bracts, 2-3 dm. long; galea shorter than the tube and the lower, lip very 

 short. (C. linearis Rydb. Bull. Torr. Bot. Club 28: 25. 1901.) Mountains 

 of Colorado. 



22. Castilleja occidentalis Torr. Ann. Lye. N. Y. 2: 230. 1828. Commonly 

 villous with weak cobwebby hairs at least in the dense and short, leafy-bracted 

 spike, often glabrous below; stems short, 8-20 cm. high: bracts comparatively 

 broad, mostly incised or cleft, the tips whitish or yellowish and more or less 

 streaked with red toward the base : calyx equally cleft to or below the middle 

 and again more or less 2-cleft: lip about half the length of the rather broad 

 galea. (C. puberula Rydb. 1. c. 31; 644.) In the alpine regions of our range. 



23. Castilleja sulphurea Rydb. Mem. N. Y. Bot. Gard. 1: 359. 1900. 

 Stems 3-5 dm. high, striate, finely puberulent or the upper portion slightly 

 villous, simple: leaves linear to lanceolate or the upper ovate, 4-5 cm. long, 

 entire or the upper cleft or lobed, acute, finely puberulent, 3-5-ribbed, light 

 green: bracts 2-3 cm. long, broadly ovate, obtuse, entire, or with a few small 

 teeth, 3-5-ribbed, puberulent, yellow or yellowish-green: calyx about 1.5 cm. 

 long, about equally cleft before and behind and cleft about 2-3 mm. at the 

 sides: corolla greenish, 2.2-2.5 cm. long; galea about three times as long as 

 the lip which is 3-cleft or lobed. [C. luteovirens Rydb. Bull. Torr. Bot. Club 

 28: 26. 1901; C. wyomingensis Rydb. (?).] Very common in moist places 

 in the mountains; throughout our range. 



16. ORTHOCARPUS Nutt. 



Annual herbs with alternate leaves and yellow, white, or purple flowers in 

 bracted spikes, the bracts often bright-colored. Calyx tubular or tubular- 

 campanulate, 4-cleft. Corolla very irregular, the tube slender, the limb bi- 

 labiate; upper lip little if any longer than the 3-lobed, 1-3-saccate lower one. 

 Stamens 4, ascending under the upper lip; anther-cells dissimilar, the outer 

 one affixed by its middle, the other pendulous from its upper end, commonly 

 small, sometimes wanting. Style filiform, with entire stigma. Capsule ob- 

 long, many-seeded. 



Corolla yellow; spike dense. 



Pubescent and hirsute; stem usually strict . . . .1. O. luteus. 



Merely puberulent; stem usually divaricately branched above . 2. O. Tolmiei. 



Corolla white, turning rose-purple . . . . . . 3. O. purpureo-albus. 



1. Orthocarpus luteus Nutt. Gen. 2: 57. 1818. Pubescent and hirsute, 

 sometimes viscid; stem strict, 1-3 dm. high: leaves linear to lanceolate, occa- 

 sionally 3-cleft, about equaling the flowers: corolla golden-yellow, about 1 cm.
