CATALOGUE. 223 



stems numerous from a shrubby base, ascending, 4-8' high ; leaves oblanceo- 

 late, mostly acute, entire, sessile with a narrowed base, the lowermost some- 

 what spatulate and short-petioled, 1-2' long by 2-4" wide; the secund 

 racemes short and rather leafy at base, with 1-4-flowered peduncles ; sepals 

 ovate or oblong-lanceolate, more or less acuminate, sometimes slightly scari- 

 ous and erose upon the margin ; corolla 8" in length, purple, dilated upward, 

 somewhat bilabiate ; anther with confluent lobes, dehiscent to the middle, 

 glabrous but hirsute-ciliate upon the margins ; sterile filament flattened toward 

 the apex, glabrous. — From the West Humboldt Mountains to Monitor Valley, 

 Nevada, and in the Wahsatch and Uintas; 6-7,000 feet altitude; June, 

 July. (788.) 



MiMULUS Lewisii, Pursh DC. Prodr. 10. 370. Puberulent and some- 

 what viscid-pubescent, erect ; leaves amplexicaul, oblong or rarely ovate, 

 acute, subdentate or denticulate, 5-7-nerved ; peduncles longer than the 

 leaves ; teeth of the dilated tubular calyx short, acuminate ; corolla large, 

 l-lf in length, deep rose-color, the throat spotted with yellow, lobes not 

 reflexed; anthers included, glabrous. — Stems 1-3° high, with leaves 2-3' 

 long; musky; growing on the banks of mountain streams. Distinct from 

 M. cardinalis, which is a Californian species, villous, with ovate erose-dentate 

 leaves, reflexed corolla-limb and subexserted villous anthers. The latter 

 probably occurs in the Sierras of Western Nevada, but 28 Anderson from 

 near Carson City has glabrous anthers and is a doubtful specimen. Rocky 

 Mountains of British America (latitude 66°) and Southern Montana ; Wind 

 River Mountains, Wyoming ; Cascade Mountains, Oregon. East Humboldt 

 Mountains, Nevada, and in the Wahsatch and Uintas ; 7-8,000 feet altitude ; 

 July, August. (789.) 



MiMULUS LUTEUS, L. DC. Pwdr. 10. 370. Glabrous or viscid-puber- 

 ulent ; stem ascending or erect ; leaves mostly erose-dentate, orbicular, ovate, 

 or somewhat oblong, the lower long-petioled and often sublyrate, the upper 

 sessile or cordate-amplexicaul, about 7-nerved, shorter than the peduncles ; 

 calyx ovate, becoming inflated, with ovate teeth, the upper one largest ; tube 

 of the dilated yellow corolla twice longer than the calyx, the lower lip 

 bearded. — ^Very variable ; stem 3'-4° high, somewhat stoloniferous at base ; 

 corolla 6^18" in length. On the western coast from Unalaska to California ; 

 Utah and Colorado. Frequent on the banks of mountain streams through 

 Nevada and Utah ; 5-6,000 feet altitude ; May-July. (790.)
