best developed specimens half-inch long ; the orifice of the calyx repandly 5-toothed, the 

 broad teeth with or without a small apiculation ; in 



Var. acutidens [M. acutidens, Greene, Bull. Calif. Acad. i. 117), the calyx-teeth more 

 salient and narrowly subulate, and leaves mostly denticulate. — Southern part of the Sierra 

 Nevada in King's River Mountains, Dr. Eisen. 



Var. latidens has the triangular-ovate and acute calyx-teeth rather conspicuous in 

 anthesis, and more so in fruit. — On the flanks of Monte Diablo, Brewer, Greene, and Chollas 

 Valley, San Diego Co., Orcutt. 



b. Leaves all contracted below into a petiole or petiole-like base, move or less 3-nerved, sparingly 

 denticulate: fructiferous calyx less ventricose and plaited, 3 or 4 lines long, and with more dis- 

 tinct ovate-triangular teeth : corolla yellow, or rarely the limb pinkish. 



M. Pulsiferse, Gkay, p. 277. — California, from Sierra Co. to Washington Terr. Varies 

 from obscurely to distinctly viscidulous-puberulent. Corolla light yellow. 



= = Fructiferous calyx campanulate to cylindraceous, little ventricose. 

 u. Leaves ovate and slendev-petioled, mostly denticulate, hardly at all nervose: corolla yellow: 

 low plants, either viscidulous or clammy-haired. 



M. peduncular is, Dougl. Erect, slender, viscid-puberulent or pubescent (not at all vil- 

 lous), a span or two high : leaves with blade only quarter or half inch long, usually much 

 surpassed by the filiform (inch or two long) spreading or divaricate peduncles : teeth of the 

 narrow and nearly glabrous calyx very short : corolla golden yellow, half-inch long and its 

 limb as broad. — Benth. Scroph. Ind. 49, in Pr.odr. wrongly referred to the next species. — 

 Sandy banks of the Columbia River, Washington Terr, and Oregon, Douglas, Sulcsdorf (who 

 indicated the excellent characters of the species), Mrs. Barrett. Also on the Kooskooskie, 

 Gei/er (part of his 474), and John Day River, Howell. 



M. floriblindus, Docgl., p. 278. Erect or soon diffuse and spreading, villous with slimy- 

 viscid hairs, somewhat musk-scented : leaves mostly dentate, little surpassed by the (half or 

 three-fourths inch long) ascending or spreading peduncles : calyx-teeth triangular, acute, a 

 third or a quarter of the length of the campanulate tube : corolla light yellow, small. 

 6. Leaves lanceolate-oblong, with several-nerved base, closely sessile: corolla light rose-color. 



M. Parishii, Greene. Erect and stout, a foot or two high, very villous with slimy viscid 

 hairs, leafy to the top : leaves an inch or two long, dentate or denticulate with salient teeth : 

 flowers mostly short-ped uncled : corolla small, little surpassing the short triangular teeth of 

 the cylindraceous calyx (this when fructiferous 5 or 6 lines long) : seeds oblong-oval, with a 

 smooth close coat. — Bull. Calif. Acad. i. 108. — Southern California, from San Bernardino 

 and Los Angeles Co. to below San Diego, Parish, Nevin, Oliver, Orcutt. 



c. Leaves narrow or small, sessile or nearly so by a tapering base; lateral ribs or nerves obscure 

 or none : low or slender plants, erect. 



1. Corolla rather large (half-inch long), conspicuously bilabiate, lower lip more or less bearded. 

 M. bioolor, Haktweg, p. 278. Viscid-pubescent : stems a span to a foot high, several- 

 flowered : corolla golden yellow with the upper lip white (not the lower as stated in the 

 original and in our description) : calyx rather strongly ribbed or angled, the teeth acute : 

 leaves dentate or denticulate. 



M. montioides, Ghat, Proc. Am. Acad. vii. 380, mainly. Glabrous, hardly viscidulous, 

 half-inch to a span high, simple or at length much branched from base : flowers few on fili- 

 form peduncles : corolla with narrow and well-exserted tube, ample throat and limb yellow 

 and purple-spotted : teeth of the narrow calyx very short and obtuse : leaves thickish, 

 spatulate to linear, obtuse. — M. rubelhis, var. latiflorus, Watson, Bot. King Exp. & p. 278, 

 M. barbatus, Greene, in Bull. Calif. Acad. i. 9, who has well taken up the species under 

 its original name in Bull. 1. c. 115. — Known only in W. Nevada and adjacent border of 

 California. 



2. Corolla small even for the small plants, little exserted, only 2 or 3 lines long, and limb not over 

 2 lines wide: throat beardless or nearly so: calyx-teeth short, triangular, mostly obtuse: pla- 

 centae of the thin-membranaceous capsule in age disposed to split in two at apex or to be 

 bipartible. 



M. Suksdarfii. An inch to barely a span high, at length much branched at base, ob- 

 scurely puberulent-viscidulous, the whole herbage and especially the fruiting calyx often
