often is only 1-2 dm. high).

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. cystopteridifolia. 



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.
