3. Mimulus parryi A. Gray, Amer. Acad. Arts and Sci. Proc. 11: 97. 



1876. 



Eunanus parryi Greene, Calif. Acad. Sci. Bui. 1: 104. 1885. 



Near Littlefield, northwestern Mohave County, about 2,000 feet 

 (Maguire 5003, 5005). Virgin River region, southwestern Utah and 

 northwestern corner of Arizona. 



4. Mimulus bigelovii A. Gray, Amer. Acad. Arts and Sci. Proc. 11: 96. 



1876. 



Eunanus bigelovii A. Gray, U. S. Rpt. Expl. Miss. Pacif. 4: 

 121. 1856. 



Mohave County, from Fort Mohave to Boulder Dam, 500 to 2,300 

 feet, open sandy places, February to April. Nevada, northwestern 

 Arizona, and southern California. 



This small plant, with its disproportionately large, beautifully 

 colored flowers, is well worth cultivating. 



5. Mimulus dentilobus Robins, and Fern., Amer. Acad. Arts and Sci. 



Proc. 30: 120. 1895. 



Mimulus parvulus Woot. and Standi., Contrib. U. S. Natl. 

 Herbarium 16: 171. 1913. 



Santa Rita Mountains, Pima County, 4,500 feet {Thornber 505, 

 etc.). Southern New Mexico, southern Arizona, and Sonora. 



Thornber's specimens correspond to the descriptions of M. dentilobus 

 in the character of the pubescence, but seem otherwise more like M, 

 glabratus. 



6. Mimulus glabratus H. B. K., Nov. Gen. et Sp. 2: 370. 1818. 

 Sacaton (Pinal County), Chiricahua Mountains, and near Bisbee 



(Cochise County), 1,300 to 5,500 feet, June. Michigan to Manitoba, 

 south to Texas, Arizona, and Central America; South America. 



Most of the Arizona specimens belong to var. fremontii (Benth.) 

 Grant {M. geyeri Ton*.), distinguished from the typical form by having 

 nearly orbicular leaf blades, these cuneate to subcordate at base, with 

 the margin entire or merely denticulate. The specimen collected at 

 Sacaton doubtless grew from seed brought down the Gila River from 

 farther east. 



7. Mimulus guttatus DC, Cat, Hort. Monsp. 127. 1813. 



Mimulus prionophyllus Greene, Leaflets 1: 190. 1905. 



Apache, Navajo, and Coconino Counties, south to Cochise and 

 Pima Counties, 1,300 to 8,000 feet, abundant in springy places and 

 along brooks, March to September, type of M. prionophyllus from 

 Willow Spring, Apache County {Palmer 527). Montana to Alaska, 

 south to northern Mexico. 



A conspicuous plant with showy yellow flowers, sometimes used for 

 salad and greens. 



Several forms, closely related to M. guttatus and represented by 

 specimens collected in Arizona, are regarded by Pennell as specifically 

 distinct (see footnote 39, p. 799, Pennell, pp. 4-6). These are: M. 

 unimaculatus Pennell, type from Sierra Ancha, Gila County {Harrison 

 7892); M. cordatus Greene, from the Chiricahua Mountains and from 

 near Tucson; M. puberulus Greene, from the Lukachukai Mountains,
