one-lipped limb, is very striking, rendering the fresh speci- 

 mens impossible to be confounded with those of any other 

 species. 



E. angustatus. 



Stemless: leaves linear, an inch or more in length, entire: 

 calyx with a narrowly contracted throat and ample folia- 

 ceous, spreading, subequal teeth, longer than the tube, cor- 

 olla as in the next species, except that the tube is very slen- 

 der and the limb less regular; upper lip considerably ex- 

 ceeding the lower: capsule short-ovate, acute, not compres- 

 sed but roundish, the thickness almost equalling the length; 

 a pair of lateral sutures manifest, but no angles: seeds few, 

 large, favose-pitted or -reticulate. — E.Coulteri, var angustatus, 

 and Mimulus tricolor, var. angustatus, Gray, 1. c. 



In the mountains from Mendocino County to Plumas and 

 southward to Fresno; collected by Bolander, Clarke and 

 Eisen. A strongly marked species in the characters of the 

 calyx and capsule. The last named organ appears to liber- 

 ate its seeds by separating from the axis at the base. This 

 may be the case in all these species. 



E. tricolor. 



Stem 1 — 2 inches high, and branching: leaves oblong-lan- 

 ceolate, entire or with some scattered serratures, an inch or 

 more long : corolla more than an inch long, very showy, light 

 and dark purple and yellow; the tube slender, gradually 

 widening into the funelforni throat; limb J inch broad, the 

 lips nearly equal, but the upper slightly larger: capsule ob- 

 long-ovate, obtuse, slightly gibbous, compressed, both edges 

 acute: seeds obovate. — Mimulus tricolor, Lindl. Journ. Hort.
