450 SUPPLEMENT. 



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 (^/- acutidens, Gxeene, 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, more or less 3-nerved, sparingly 

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

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



M. Pulsiferee, GRAY, p. 277. California, from Sierra Co. to Washington Terr. Varies 

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



= = Fructiferous calyx campanulate to cylindraceous, little ventricose. 



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

 low plant?, 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 bv 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 Prodr. wrongly referred to the next species. 

 Sandv banks of the Columbia River, Washington Terr, and Oregon, Douglas, Suksdorf (who 

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

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



M. floribundus, DODGL., 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. 



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

 M. Parishii, GREEXE. 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-peduncled : 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. 10S. Southern California, from San Bernardino 

 and Los Angeles Co. to below San Diego, Parish, ^ T ei-in, Oliver, Orrutt. 



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

 or none: low or slender plants, erect. 



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

 M. bicolor, HAP.TWKO, 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. rnontioides, GRAY, 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. rule/Ins, var. /atiflorns, Watson. Bot. King Exp. & p. 278. 

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

 its original name in Bull. I.e. 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 

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



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

 bipartible. 



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

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