224 BOTANY. 



Var. Flowers small, 3-6" in length ; stems 2-10' higli ; mostly depau- 

 perate specimens.-It is difficult to draw a line of distinction between M. 

 luteus and M. glahratus, and so far as North American specimens, at least, 

 are concerned, there can be but one species. Even the same plant may show 

 reduced flowers at the base and large well-developed corollas above. M. pro- 

 pinquus, Lindl, is probably the same. M. Jamesii is more distinct in its habit 

 and will doubtless be retained, though at one time referred to M. glahratus.

 feet altitude ; June-September. (791.) 



Var. ALPINTJS, Gray. Stems 3' high from a decumbent or creeping base, 

 1-3-flowered ; leaves mostly sessile, somewhat entire.— Collected by Parry

MiMULUS PEiMULOiDES, Benth. DC. Prodr. 10. 372. Glabrous or 

 sparingly pilose, stoloniferous ; stem 2-4' high, somewhat winged; leaves

 peduncles few, (1-2,) elongated, 1-2' in length ; calyx tubular, 3-4" long, 

 but shghtly dilated in fruit, the teeth short and equal ; corolla yellow, 4' in 

 length. — A pretty subalpine species. Cascade and Blue Mountains of "Wash- 

 ington and Oregon Territories ; Cahfornia. East Humboldt Mountains, Ne- 

 vada ; 8,000 feet altitude ; August. Collected also by Anderson near Carson 

 ■City. (793.) 



MiMULUS FLOEIBUNDUS, Dougl. DC. Pwdv. 10. 372. Viscidly pilose ; 

 stems slender, 2-18' long, diflfusely branching at the base, ascending; leaves 

 petioled, 3-18" in length, ovate, dentate or denticulate, the lower subcordate, 

 somewhat pinnately 5-7-nerved ; peduncles axillary to nearly every leaf, soli- 

 tary, slender, mostly exceeding the leaves ; calyx ovate, 5-angled, with short

 longer than the calyx. — Washington Territory to California. Truckee Val- 

 ley and East Humboldt Mountains, Nevada, and in the Wahsatch ; 4,500- 

 6,000 feet altitude ; July-September. (794.) 



MiMULUS MOSCHATUS, Dougl. DC. Prodr. 10. 372. Stem viscidly 

 woolly, branching from the base, prostrate or suberect ; leaves on short peti- 

 oles, ovate, acute, dentate, pinnately nerved, viscidly pilose ; peduncles 

 usually a little shorter than the leaves, solitary ; calyx tubular, becoming 

 ovate, the teeth lanceolate, acuminate, somewhat unequal ; corolla-limb yel-
