Mrs. R. M. Austin, Butte County, Cal., 1883. A grace- 

 ful species, and, I believe, the only glaucous one. 



M. nudatus, Curran in herb. 



Somewhat glandular-puberulent and the herbage purple; 

 6 — 10 inches high, the stem and few branches terete and 

 rather slender: leaves inconspicuous, 1 — 3 lines wide, a half 

 inch or more long, on petioles of equal length or the upper- 

 most sessile, denticulate: pedicels an inch long, spreading: 

 calyx oblong, not purple-dotted, teeth not very unequal, the 

 orifice closed by the folding of the two lower teeth over the 

 others: corolla J — | inch long, deep yellow; the ample limb 

 bilabiate; the throat strongly bearded: seeds linear-oblong, 

 striate but not reticulate. 



Kelsey Mountain, Lake County, June, 1884, Mrs. Curran. 



A pretty species, the narrow leaves few and inconspicu- 

 ous, the long pedicels nearly divaricate, the large, bright 

 yellow corollas in fine contrast with the purple of all other 

 parts of the plant. 



* * Stems freely branching, often decumbent, diffuse or creep- 

 ing: corollas smaller. 



■+- Annuals; corollas manifestly bilabiate, mostly yellow. 



M. laciniatus, Gray, 1. c. 



Glabrous or slightly pubescent : filiform stems diffuse, a 

 span or less long: leaves an inch or less in length, variously 

 lobed or cleft, sometimes pinnately cleft or parted, on fili- 

 form petioles: pedicels filiform, longer than the leaves: calyx 

 ovate, 2 — 4 lines long, gibbous, the upper tooth largest, pur- 

 ple-dotted: corolla 2 lines long. — M. Eiseni, Kellogg, Proc.
