Northern parts of California, in the Sierras, and also at 

 low altitudes in valleys, in Trinity and Siskiyou counties. 



M. inconspicuus, Gray. 



From glabrous to puberulent-glandular, 2 — 12 inches 

 high, simple or freely brandling from the base: leaves ovate 

 to ovate-lanceolate, entire or sparingly toothed, 3 — 5-nerved, 

 |~1 inch long, sessile by a broad base or tapering to a 

 short petiole: pedicels equaling the flowers, in fruit becom- 

 ing much longer: corolla 3—5 lines long, the limb small, 

 ochroleucous or "yellow or rose color:" calyx oval, 3 — 6 lines 

 long; teeth nearly equal, minute or very short, or ovate-tri- 

 angular and conspicuous. — Pac. R. Rep. IV. 120, and 1. c. 



From the banks of the Columbia to the Lower Californian 

 peninsula. As here accepted a variable species, and one 

 which were perhaps better re>tricted to the original plant 

 with calyx appearing truncate by the minuteness of the teeth. 

 The northern plant, ranging from Modoc County, California 

 (Mrs. Austin), to Washington Territory (Prof. ' E. W. Hil- 

 gard, 1882, and Suksdorf, 1883, No. 203,) is glandular, has 

 narrow, always petiolate leaves and very small flowers. Mr. 

 Suksdorf's specimen in the herbarium of Dr. Gray is erro- 

 neously put along with M. rubellus, from which the calyx- 

 teeth, connivent and nearly closing the oriiice, readily dis- 

 tinguish it. This peculiarity of the calyx marks all our 

 middle Californian, even the largest forms, and ought per- 

 haps to be taken for the good character of a new species. 

 However, I know the original M. inconspicuus only by a few 

 calyces kindly furnished me by the author of the species 5 

 and so, do not venture to propose distinctly here, the separ- 

 ation which I have little doubt needs to be made. The 

 flowers in the plant of middle California are neither red nor 

 yellow, but only yellowish, or dingy white; paler than any 

 other Mimulus known to me. 



M rubellus, Gray. 



Very minutely and rather sparingly glandular-puberulent,
