MIMULUS. 



M. glutinosus is Diplacus glutinosus in Bay-Reg. Bo* # 2, 3, and 4 make the 

 genus Eunanus in Bay-Reg. Bot., and M. exilis is Mimetanthe pilosa, Greene. 



3. Eunanus. 



Miniulus Austinae, Greene. Near M. mephiticus, but odorless and scarcely viscid, 

 1-3 inches high, much branched, leaves spatulate 6 lines long or more, entire with 3-5 

 parallel veins: calyx teeth nearly equal: corolla yellow, throat purple dotted, tube long 

 and slender, limb broad: pod attenuate, greatly surpassing the calyx. Modoc Co. 



M.Cusickii, Greene. A foot high or less, simple or branched; leaves broadly-ovate, 

 very acute, entire sessile, 1 inch long or longer: calyx teeth very unequal, acute: corolla 

 red-purple, tube slender, limb rotate, nearly regular, 6-10 lines broad. Or. and Wash. 



5. Eumimulus. 



According to Greene Mimulus luteus is a South American species quite distinct 

 from our species which has borne this name, and should be known by the name given to 

 it long ago by an eminent French botanist; viz. 



M. guttatus, D. C. A very variable species, of which two varieties described by 

 Greene are the most common; var. grandis, Greene, a stout perennial 2-5 feet high 

 with round stems, usually simple above the decumbent base; the stem leaves orbicular 

 to round-ovate, and those from the base petiolate and sometimes lyrate; the flowers an 

 inch or more long, light yellow with red dotted throat, in racemes a foot or more in 

 length: var. insignis, Greene, probably always annual, less than 2 feet high, the flowers 

 with red dotted calyx and corolla with large, dark red spots. But there are too many 

 intermediate forms to make these names worth much. 



M. arvensis, Greene. Annual, erect, simple, quadrangular sterns, 1-2 feet high or 

 more: lower leaves coarsely toothed and pastate or lyrate, the floral soft-hairy beneath: 

 calyx 3-4 lines long, purple dotted, nearly truncate, becoming in fruit 6-8 lines long: 

 pod compressed, nearly orbicular. 



M. subreniformis, Greene. Slender, 2-6 inches high: leaves 2-5 lines long, reni. 

 form, with remote teeth, purplish beneath, roughish above, with short white hairs: corolla 

 little exceeding the calyx, yellow with dark dots. Shasta Co. 



M. marmoratus, Greene. Decumbent, annual, 4-8 inches long, sparsely hairy: 

 stem acutely angled: leaves ovate, reniform, toothed, red beneath, 6-9 lines long: calyx 

 mottled, 4-5 lines long: corolla an inch or less in length, with slender tube and ample 

 limb, the middle lobe large, hairy, with a red spot and dots. Knight's Ferry. F. W. 

 Bancroft. 



M. deflexus, Wat. Slender, 2-3 inches high: leaves linear or broader, entire, less 

 than 6 lines long: pedicels longer, spreading or reflexed: calyx slightly angled, nearly 

 equally toothed, less than 3 lines long: corolla 6-8 lines long, upper lip deep purple,
