﻿Nelson : New Plants from Wyoming 205 



r 



dense, 1-2 dm. long, elongating in fruit : flowers blue, sub-verti- 

 cillate, standard glabrous ; bracts minute or wanting ; pedicels 

 5-8 mm. long, stout in fruit : pods villous-pubescent, 2.5-4 cm. 

 long, normally 6-seeded. 



A good species, possibly somewhat local ; abundant in the 



Laramie hills, where it has several times been collected and fre- 



quently observed. It has not been secured elsewhere in the State. 



It loves a moist soil, rich in humus ; is not found on the open plain 



but in aspen or other thickets or even among sage-brush on the 



slopes where snowdrifts accumulate and lie late in the spring. It 



develops early, almost out of the snow-drifts, and begins to show 



its spikes of blue even before the aspens are in leaf. 



Heretofore carelessly confused with L. leucophylhts Dougl. 



under which name I have distributed it as no. 151. 



Type specimens in Herb. Univ. of Wyoming, no. 151, Lara- 

 mie Hills, June 2, 1894, and no. 71, a well-fruited specimen from 

 the same locality by Mr. Elias Nelson, who first called my atten- 

 tion to the marked differences between these specimens and L. 

 leucophylhts. 



Lesquerella cur vi pes. 



Perennial : stems tufted on the expanded crown of the single, 

 long, slender, woody root, numerous (30—60), nearly simple, spread- 

 ing-assurgent, 1 }4~3 dm. long ; finely stellate pubescent through- 

 out : leaves entire, cauline, linear to oblanceolate, tapering gradually 

 into the somewhat margined petiole, 3-6 cm. in length, radical 

 oblanceolate to obovate with margined petioles : flowers unknown : 

 pods ovate, acute, distinctly compressed at summit, gibbously con- 

 vex towards the base, about 8 mm. long, the slender style two-thirds 

 as long: slender pedicels divaricate, 1—2 cm. long, doubly curved, 

 the proximal part upward, the distal downward with ascending tip 

 bearing the erect pod : seeds two in each cell, rarely one or three. 



It most resembles L. montana Nutt. from which it differs in its 

 larger size, more numerous stems, its somewhat veiny leaves, 

 larger, compressed pod and fewer seeds. 



Collected in the northern Big Horn Mountains, on the Dome 

 Lake road, at about 9000 ft., July 19, 1896, no. 2424. 



Lesquerella rosulata. 



Annual, or possibly more enduring, finely stellate pubescent 

 throughout : stems few, 1-2 dm. long, ascending, flortferous one-
