Var. verbenaceus (Greene) Kearn. & Peeb., of Arizona, has corolla tube nearly 

 twice as long as the calyx. 



4. Mimulus floribundus Dougl. Fig. 695.

 branched from the base, somewhat weak, often climbing over moist rocks; leaves 

 scattered, thin, ovate to ovate-lanceolate, 1.5-5 cm. long, 1-3 cm. wide, acute, 

 dentate with short salient teeth, ciliate, the base broad, mostly truncate or sub- 

 cordate, 3- or 5-nerved, usually shorter than the internodes; petioles longer or 

 shorter than the blade, sometimes slightly winged or occasionally essentially 

 lacking; pedicels filiform, frequently shorter than the leaves and more or less 

 spreading at maturity; calyx plicate-carinate, slightly campanulate, 4-7 mm. long, 

 broadly ovate in fruit and 6-10 mm. long, often spotted or tinged with red; 

 calyx teeth triangular, lanceolate, 1-1.5 mm. long, ciliate, equal; corolla cylindrical 

 to funnelform, 7-14 mm. long, yellow, tube slightly exserted, throat short, 

 ampliate, dotted or streaked with red, lobes unequal, mostly erect, short, rounded, 

 the lower lip sometimes slightly spreading; style and stamens glabrous, included, 

 stigma lips equal and rounded; capsule chartaceous, shorter than the calyx, oblong, 

 placentae completely adherent; seeds oval, longitudinally wrinkled. 



In wet sand, growing in streams and in marshes, in N.M. (Rio Arriba Co.) and 

 Ariz. (Apache and Coconino, s. to Yavapai, Graham, Santa Cruz and Pima cos.), 

 Apr.-Sept.; Wyo. to B.C., s. to n. Mex. and Calif. 



5. Mimulus rubellus Gray. Fig. 696. 



Annual, glandular-puberulent to almost glabrate, the erect stems often much- 

 branched, to 2 dm. high; leaves sessile or with the lowest smaller and petioled, 

 elliptic-oblong to elliptic-lanceolate, entire or only slightly toothed, 3-veined, 

 to about 2 cm. long; pedicels to 22 mm. long; calyx 5-9 mm. long, often reddish, 

 ridge- to wing-angled, its ciliate lobes low-triangular or its mucronate tips less 

 than 0.5 mm. long; corolla yellow throughout or the lobes purple-red, 7-9 mm. 

 long, the throat narrow, ventrally 2-ridged and puberulent, the orifice open and 

 the slightly spreading lobes notched; anthers glabrous; capsule 4 mm. long, not 

 dehiscing through septum apex. 



In moist or wet places, seepage about springs, creek beds and in mud along 

 streams, in extreme w. Tex., N. M. (Sierra and Dona Ana cos.) and Ariz. 

 (Coconino and Mohave, s. to Greenlee, Cochise, Santa Cruz and Pima cos.), 

 Apr.-June; from w. Tex., N.M., Ariz., Wyo. and s. Colo, to Calif. 



6. Mimulus primuloides Benth. Fig. 695. 



A variable perennial, stoloniferous or reproducing by surface runners or by 

 bulbils attached to the underground stems, subacaulescent with radical leaves or 

 the stems 3-10 cm. high, bearing several pairs of leaves, internodes close together 

 or almost as long as the leaves, glabrous or viscid-pilose with long soft hairs; 

 leaves broadly obovate, oblong or sometimes cuneate, tapering to a narrow some-
