SCROPHULARIACEiE. 449 



== Leaves -S-S-nerved at the haso, from denticulate to saliently and irregularly or doubly dentate, 

 sometiiivc's incised, mostl}' petioled. 



M„ nasutUS, Grekne. Quite glivlirous, or lierbnge minutely pubescent ; larger forms a 

 foot or two liigli, erect, with 4-angled stout stem, corolla and fruiting calyx each half to two- 

 thirds inch long, and rounded leaves one or two inches in diameter; exiguous forms abound- 

 ing with the same (mostly flowering earlier or when drier), diffuse, delicate, thin-leaved, 

 reduced to a span or so or even an inch or two high, with rounded leaves from half-inch to 

 a line or two broad, fruiting calyx fi'om 5 to 3 lines long, and very small hardly exserted 

 corolla : leaves chiefly orbicular or round-ovate and lower subcordate : calyx broadly ven- 

 tricose-ovate in fruit, conspicuously pointed by the triangular-lanceolate projecting upper 

 tooth : c(^rolla commonly with a crimson-purple spot on the lower lip. — M. nasutas & M. 

 microplii/llus, Greene, Bull. Calif. Acad. i. Ill, 112, excl. syn. M. li/ratus, &c. J\I. luteus, var. 

 depatiperatns, in part, of p. 277. — Common from S. California to Brit. Columbia, and east- 

 ward into Nevada, along streams and in canons, often growing with M. l-uteus. 



M. nudatUS, Curran. Minutely pubescent and viscidulous, glabrate in age, diffusely 

 branched from the very base, a span or two high, with stems and sometimes foliage purple- 

 tinged : leaves ovate to lanceolate, from denticulate to strongly and acutely dentate, taper- 

 ing into a margined petiole (both together seldom inch long), u])per much surpassed by the 

 filift)rin at length divergent peduncles : corolla half to three-fourths inch long, with ample 

 limb (I)right yellow) : fructiferous calyx oblong-ovoid in fruit, then half-inch long or more 

 and gibbous, with closed mouth; the short triangular teeth nearly equal and alike, but four 

 closely inttexed upon the slightly projecting uppermost. — Greene, Bull. Calif. Acad. i. 114, 

 name not well chosen, except for the (chiefly fruiting) specimens described. M. dentatiis, 

 Gray, in Pacif. R. Rep. iv. 120, partly (leafy and floriferous), not Nutt. — California in the 

 Sierra Nevada, near Murphy's, Blijelow, and on Table Mountain, Mrs. Ames. Also Kelsey 

 Mountain in Lake Co., Mrs. La ijiic- Curran. 



= = Leaves not nervo.se but laciniately dissected, narrow. 



M. laciniatus, Gray, p. 277. Glabrous or nearly so, a span to a foot high, slender : leaves 

 spatulate-lanccolate or narrower in outline, from 3-5-cleft to irregularly once or twice pin- 

 nately parted into narrow small lol)es : corolla 2 to 4 lines long, narrow, hardly twice the 

 length of the calyx, pale yellow : fructiferous calyx 2 or 3 lines long, gibbous-campanulate 

 with acute base, little inflated; the triangular short teeth only slightly unetjual. — M. 

 Eisenii, Kellogg, Proc. Calif. Acad. vii. 89. — Sierra Nevada, in Mariposa Co., California, 



. recently collected by Congdoit, Mrs. Laijnc-Cmran, Meehan, Ike. 



++++++ Small-flowered, very minutely glandular-puberulent or glabrou.', but viscidulous, and 



when much so musk -scented : calyx campanulate-oblong, hardly at all unequal-sided at maturity 



or ventricose, I)ut nearly tilled by the oblong capsule; the shoi't-tnothed orifice as if truncate and 



mod(!ratcly oblique; the upper and two lateial at length triangular-subulate teeth a little shorter 



than (he two larger and rounded-obtuse more united lower ones! 



M. alsinoides, Bougl., p. 277. — British Columbia to N. California, first coll. by Menzies. 



Runs down to the e.xceedingly tiny specimens of Scouler, &c. (var. minimus), while the 



larger are even a foot long, and some of the (5-nerved at base) leaves are two inches long, 



including the petiole. Nuttall distributed this species under the name of M. tenelhis. Now 



that its peculiar characters are indicated it cannot be mistaken. Yet it had been confounded 



with some other species, and with M. Pn/siJ'rra>, Greene, 1. c. Suksdorf remarks that the 



peduncles carry the capsules as closely as possible to the rocks. 



•H- ++ ++ ++ Small-flowered, or sometimes rather large-flowered for a small plant: calyx not gib- 

 bous nor manifestly oblique at orifice; the teeth equal or nearly so, and erect in fruit; corolla 

 from yellow or rarely white to rose or crimson-red. 



^ Fructiferous calyx more or less ovoid and ventricose, somewhat narrowed at the orifice, (he 

 short teeth disposed to connive: plants low and erect or ascending, glabrous or barely viscidu- 

 lous-pubcrulent, with erect or ascending fructiferous peduncles. 



a. Leaves all or all but the lowermost sessile by a broad obscurely 3-nerved base, entire or occa- 

 sionally denticulate; mature fructiferous calyx much ventricose and plaited-angled, 4 to 6 lines 

 long: corolla rose-purple or pink, sometimes "white." 

 M. inCOnspicUUS, Gray, p. 278. Occurs here and there from middle to .southern parts 

 of California. Well-developed plants a span to a foot high, essentially glabrous; corolla in
