 calyx viscid-pubescent' or villous : herbage often pubescent : leaves linear-lanceolate, 

 mainly entire. — i)(>/«cus hmjijiorus, Nutt. 1. c — From Santa Barbara southward. 

 § 3. EuMiMULDS, Gray. Herbaceous : proper tube of the corolla mostly 

 included in the plicately carinate-angled 5-toothed calyx (the teeth traversed by 

 the strong nerve) : style glabrous : stigma bilamellar, the lobes or lips ovate or 

 rotund an°d equal : placenta remaining united in the axis of the capsule (or partly 

 dividing, in M. rubellus completely), from which the thin and usually membra- 

 naceous valves tardily separate. 



* Larce-fiowered and perennial western species: corolla li to 2 inches long, red or rose-color, 



with cvlindrical body longer than the limb; calyx oblong-prismatic ; the short teeth nearly equal: 



anthers either villous or almost glabrous in the same species: pedicels elongated : capsule oblong: 



leaves several-nerved from the base: seeds with a dull and loose epidermis, longitudinally 



wrinided. 



M cardinalis, Dougl. Villous and viscid, 2 to 4 feet high : leaves ovate, or the lower 



obovate-lanceol'ate ; the upper connate ; all erose-dentate : corolla scarlet, with remarkably 



oblique limb ; upper lip erect and the lobes turned back ; lower reflexed : stamens ex- 



serted. — Lindl. Hort. Trans, ii. 70, t. 3; Brit. Fl. Card. ser. 2, t. p58; Hook. Bot. Mag.

M Lewisii, Pursh. More slender, greener, and with minute or finer pubescence: 

 leaves from' oblong-ovate to lanceolate, denticulate: corolla rose-red or paler, with tube 

 and throat proportionally longer; roundish lobes all spreading: stamens included. —Fl.

 Brit. Fl. Gar'd. ser. 2, t. 210.— Shady and moist or wet ground, Brit. Columbia to Califor- 

 nia along the whole length of the Sierra Nevada, east to Montana and Utah. 

 * * Moderatelv large flowered eastern species, perennial. glabrous: corolla violet, at most an inc> 

 lone with narrow tube and throat more or less exceeding the nearly equal calyx, and personate 

 limb: fructiferous calyx oblong: leaves throughout pinnately vemed: seeds not wrinkled. 

 (Corolla rarely varying to white, not very rarely with the lateral lobes of the lower lip exterior 

 in the bud!) 

 M ringens L. Stem square, 2 feet high : leaves oblong or lanceolate, closely sessile by 

 an auriculate partly clasping base, serrate : pedicels longer than the flower : calyx-teeth 

 subulate, slender: seed-coat rather loose, cellular. — Hort. Ups. 176, t. i. ; Lam. 111. t.523; 

 Bot. Mag. t. 283. — Wet places, Canada to Iowa and south to Texas. 

 M alatus Solander. Stem somewhat wing-angled : leaves ovate to ovate-lanceolate, 

 less acutely serrate, tapering at base into a margined petiole : pedicels shorter than the 

 calyx • teeth of the latter short and broad with abrupt mucronate tips : seed-coat close 

 and smooth. -Ait. Kew. ii. 301 ;.Lodd. Bot. Cab. t. 410; Bart. Fl. Am. Sept. iii. t. 94.- 

 Wet places, W. New England to Illinois, and south to Texas. 



* * * Small- or moderately large-tlowered mainly western species: corolla from yellow or some- 

 thnes partly white to browh-red or crimson ; the throat broad and open: seeds with a thm and 

 smooth or shining (or in ^f. luUus duller and reticulate-striate) coat. 

 H- Leafy-stemmed, not villous, nor leaves pinnately veined, but with 3 to 7 primary veins from or 



near the base, and hardly any, or only weak ones, from above the middle of the midnb. 

 ++ Calyx oblique at the orifice ; the posterior tooth largest: leaves mostly broad, dentate, at least 



the lower petioled : root fibrous. 

 = Perennial by stolons or creeping branches : upper leaves sessile by a broad or somewhat clasp- 

 ing base : lower lip of the corolla bearded at the throat. 

 M. Jamesii, Torr. & Gray. Diffuse and creeping, freely rooting, glabrate : leaves 

 roundish and often reniform, from denticulate to nearly entire (4 to 12 lines long), all but 

 the uppermost with margined petioles: flowers all axillary and slender-pedicelled: corolla 

 light yellow, 4 to 6 lines long : fructiferous calyx campanulate, about 3 lines long : seeds 

 oval, shining, almost smooth. — Benth. in DC. I.e. 371 (with var. Fremontii) ; Gray, 

 Man. ed. 2, 287. M. glabratus, Gray in Bot. Mex. Bound, 116, partly, hardly of HBK. — 

 In water or wet places, usually in springs, Illinois to Upper Michigan and Minnesota, west 

 to the Rocky Mountains in Montana, thence south to New Mexico and Arizona. (Adja-
