* Pedicularis ctenophora Rydb. Bull. Torr. Bot. Club, 24: 292. 



Like P. co)itorta, but the corolla purplish, the calyx more gibbous 

 above, purple-striate and more or less villous at the base, and the 

 bracts larger. Grows on mountains, at an altitude of about 2500 m. 



Montana: Lima, 1895, Rydberg, 278^. 



Wyoming: Big Horn Mts., 1898, Tweedy. 



Washington: Mt. Stewart, 1883, T. S. Brandeg-ee, 1026. 



* Pedicularis Hallii. 



Perennial, from a short rootstock, glabrous up to the inflorescence ; 

 stem 1-1.5 dm. high, almost leafless; basal leaves numerous, deeply 

 pinnately parted into oblong-linear divisions, which are finely crenate- 

 serrate ; bracts deeply dissected ; calyx more or less villous ; corolla 

 nearly 2 cm. long, purple, the galea falcate with a conical beak, 

 without teeth, the lip very broad, crenulate, about half as long as 

 the galea. 



Nearest related to P. Parrxi, with which it has been con- 

 fused. The form of the leaves and of the corolla is almost the same 

 in the two, but the color of the corolla of P. Parryi is ochroleucous 

 or yellow, and the calyx, in all specimens seen by me, glabrate. Most 

 specimens labeled P. Pariyi from Montana and northern Wyo- 

 ming probably belong here. The characters in Gray's Synoptical 

 Flora (2^: 306), "or the inflorescence slightly pubescent," proba- 

 bly refer to this species. I have dedicated this to Dr. Charles H. 

 Hall, who is one of its collectors. Grows on high mountains, at 

 an altitude of about 3000 m.
