Aug. 1882; Parish Bros. No. 1465. Collected again in the 

 summer of 1884, by the Rev. J. C. Nevin, and Mr. J. C. 

 Oliver, in Los Angeles County, and by Mr. C. R. Orcutt, on 

 the peninsula of Lower California, in September of the same 

 year. The plant is one of the stoutest and tallest of its 

 genus, but the root is pretty clearly annual. 



Only in respect to the shape and color of the corolla is 

 the species to be associated with 31. Lewisii. It might al- 

 most as well go into the next section. 



§ 3. Simiolus. Stems usually flaccid, the branches mostly weak 

 and decumbent, sometimes creeping and rooting: herbage in most 

 species pcde green, truly viscid in one or two, slimy in m<< uy, fre- 

 quently exhaling the odor of musk: corolla pure yellow or crimson- 

 dotted, not rarely red-purple; the throat usually funnelform-en- 

 larged; the limb varying from personate to nearly regular. — 

 § Eumimulus, Gray, in part. 



Plants inhabiting chiefly the western parts of America, rang- 

 ing from the Aleutian Islands to Patagonia. The bulk of the 

 species, being North American, are herein described. 



* Stems exect, simple or with a few ascending branches; corol- 

 las strongly bilabiate; the lower lip bonded. 



-s- Perennials; large-flowered. 



M. dentatus, Nutt. 



Root fibrous: stem simple, slender, a foot or two high; 

 pubescent with short, pilose hairs: leaves ovate, acute, 

 coarsely serrate-toothed, an inch long on very short petioles : 

 peduncles about equaling the leaves: calyx-teeth triangular, 

 acuminate, subeqoal: corolla golden yellow, an inch or more 

 long with ample throat twice the length of the tube, purple- 

 dotted, strongly bearded to the base in two lines; bilabiate 

 limb an inch broad, its lobes entire and ciliolate: seed ovate, 

 acute, scrobiculate, of a reddish brown hue. — DC. Prod. X. 

 372; Gray, Bot. Cal. I. 567; Bot. Gaz. VII. 112, excl. var. 

 gracilis, which is M. moniliformis, Greene.
