7. Mimulus Eastwoodiae Rydb. 



Plants usually densely woolly-canescent; stems terete, short, more or less pro- 

 cumbent, from a creeping rootstock or from short stolons; leaves broadly obovate 

 or oblong, 2-5 cm. long, to 2 cm. wide, acute, coarsely and saliently dentate 

 along the upper half, tapering to a broad sessile base, the lower leaves sometimes 

 spatulate or cuneate, frequently reddish on the lower surface; flowers few, mostly 

 solitary; pedicels slender, usually longer than the leaves; calyx somewhat funnel- 

 form, 2.2-2.7 cm. long; calyx teeth triangular, acute or subulate, ciliate, slightly 

 unequal, 4-6 mm. long; corolla 3.5-4 cm. long, crimson, tube broadly funnelform, 

 exserted less than twice its length, more or less tinged with yellow, throat ampliate, 

 upper lip erect, lower erect or somewhat spreading, lobes nearly equal, emargin- 

 ate; stamens much-exserted, anthers yellow and densely bearded; style and stigma 

 nearly as long as the corolla, stigma narrowly oblong to spatulate; capsule un- 

 known. 



In wet shaded places such as seepage about springs, in Ariz. (Apache, Navajo, 

 Coconino and Mohave cos.), Apr.-July; also Ut. and Nev. 



8. Mimulus pilosus (Benth.) Wats. 



Plant to about 3 dm. tall, eventually much-branched, leafy, soft-villous and 

 slightly viscid, rarely glabrate, flowering from near the base; leaves sessile, lanceo- 

 late to narrowly oblong, entire, obscurely 3-nerved at base, the lower leaves 

 surpassing (the upper scarcely equaling) the pedicels; calyx oblique at orifice, 

 the tube somewhat 5-suIcate below the sinuses, the posterior tooth equaling the 

 tube; corolla 6-8 mm. long, rather obscurely bilabiate, the lobes nearly equal, 

 bright-yellow and usually with a pair of brown-purple spots on the lower lip; 

 capsule long-ovoid, acute. 



Wet sandy soils along streams and about pools, in Ariz. (Yavapai, Graham, 

 Gila, Pinal, Maricopa and Pima cos.), Apr.-Aug.; Nev. and Ore., s. to Ariz, and 

 s. Calif. 



9. Mimulus dentilobus Robins. & Fern. Fig. 696. 



Low creeping plants, rooting from the nodes and forming dense mats, the 

 terete stems nearly glabrous or sparsely pubescent, to 5 cm. high; leaves broadly 

 ovate to suborbicular, 2-7 mm. long, 2-5 mm. wide, dentate to crenate or nearly 

 entire, mostly with winged petioles shorter than the blade, more or less covered 

 with stiff white hairs; flowers few, axillary or terminal; pedicels slender, almost 

 filiform, pubescent, much-exceeding the leaves; mature calyx turbinate, 5-7 mm. 

 long, sparsely pubescent or rarely glabrous, with triangular acute teeth; corolla
