the leaves short (8 mm. or less long), not narrowed at the base. 

 Corolla yellow or ochroleucous. 5. P. Parryi. 



Corolla purple. 6. P. Hallii. 



Beak much shorter than the width of the galea; lip ascending; lower primary 



divisions of the leaves 8-30 mm. long, usually narrowed at the base. 

 Plant 1-2 dm. high; bracts ovate, all shorter than the flowers. 



7. P. Canbyi. 

 Plant 3-6 dm. high; bracts linear, oblong, or lanceolate, the lower equalling or 



exceeding the flowers. 8. P. siifolia. 



Galea not produced into a distinct beak, but often with two lateral teeth near the apex. 

 Leaves pinnately divided or lobed. 



Leaves divided to the midrib or nearly so into narrow, acute, dentate or serrate 



or incised divisions. 

 Galea distinctly arcuate; stems 2-15 dm. high (except in P. scopulorum, which 



often is only 1-2 dm. high). 



Galea toothless; plant 4-10 dm. high; lip not reaching the tip of the gatea. 

 Corolla pale yellow; spike elongate, 6-30 cm. long; bracts lanceolate, 



usually produced and exceeding the flowers. 9. P. bracteosa. 

 Corolla tinged with purple; spike 3-10 cm. long; bracts ovate, short- 

 acuminate and about half as long as the flowers. 



10. P. montanensis. 

 Galea with two lateral teeth. 



Plant tall, 3-15 dm. high; corolla sordid yellow, 3-3.5 cm. long; lip 



almost reaching the tip of the galea. 11. P. Grayi. 



Plant lower, 1-4 dm. high; corolla purple, 2-2.5 cm. long; lip not reach- 

 ing the tip of the galea. 



Leaves divided to the midrib, i. e., rachis not winged; divisions 



incised. 12. P. cystopteridi folia. 



Leaves not quite divided to the midrib, i. e., rachis winged; divisions 



merely dentate. 13. P. scopulorum. 



Galea scarcely arcuate, nearly straight, except the hood-like rounded apex, 



usually toothless; plant less than 1 dm. high. 

 Spike verj dense, densely lanate; lower lip almost equalling the galea. 



14. P. lanata. 

 Spike laxer, sparingly if at all lanate; lower lip of the corolla much shorter 



than the upper. 

 Corolla 18-22 mm. long; lower lip 5 mm. long; galea merely tinged 



with purple. 15. P. Oederi. 



Corolla about 12 mm. long; lower lip of the corolla about 3 mm. long;
