Mimulus gratioloides sp. nov. 



A low, branched annual of more or less reddish color, gener- 

 ally less than i dm. high, somewhat viscid puberulent especially 

 above. Leaves oblong-lanceolate, sessile, about i cm. long, sinu- 

 ate-dentate : pedicels slender, in fruit i 5-20 mm. long ; calyx 7- 



8 mm. long, cylindraceous in fruit : lobes subequal, short, broadly 

 ovate, acute, ciliate on the margins ; corolla yellow, about i cm. 

 long and 3 mm. broad, only slightly bilabiate : throat beardless. 



This species is nearest related to M. rubellns and the specimens 

 from Colorado referred to that species may belong here. M. 

 gratioloides differs, however, in the smaller yellow corolla and the 

 acute calyx-lobes. It grows in exposed places among rocks and 

 gravel at an altitude of about 2300 m.

Pedicularis lunata sp. nov. 



A perennial, perfectly glabrous up to the inflorescense, with a 

 rather stout, but simple rootstock : stem about 4 dm. high, slightly 

 striate and purplish: leaves alternate, dark green, 5-12 cm. long, 

 pinnately divided to near the midrib ; segments linear or linear- 

 oblong, crenate : spike i 5-20 cm. long, rather lax ; bracts pecti- 

 nately divided with prolonged endlobes, the lower often equal- 

 ing the flowers in length, slightly arachnoid villous : calyx about 



9 mm. long ; its teeth broadly lanceolate, about 3 mm. long : cor- 

 olla pinkish, over 2 cm. long ; its tube about twice as long as the 

 calyx, strongly curved ; galea strongly arcuate, produced into a 

 rather long beak and almost crescent-shaped ; lower lip almost 

 meeting the beak of the upper, very broad, indistinctly 3-lobed 

 with large rounded lateral lobes. 



The very broad lower lip, and long-beaked galea suggest 

 somewhat P. contorta and P. etenopJiora, but the corolla-tube is
