8. M. latidens. Annual, slender, usually much branched from the 

 base, 3 10 in. high, glandular-puberulent: leaves ovate to ovate-lanceo- 

 late, i< 1 in. long, 3 5-nerved, entire or sparingly toothed, short- 

 petioled or sessile: pedicels as long as the fl., in fr. much longer: calyx 

 oval, 36 lines long; teeth triangular-ovate: corolla 35 lines long, 

 nearly regular, but limb very small, white; throat yellowish Rich low 

 plains of the lower Sacramento and southward. April, May. 



10. MIMETANTHE, Greene. Villous and glandular ill-scented herb, 

 with corolla of Mimulus', but calyx 5-cleft and slightly 5-sulcate, not 

 angled. Style glabrous; stigma bilamellar. Capsule oblong-ovate, 

 acuminate, chartaceous, dehiscent by the upper suture, and to just past 

 the apex on the lower, the partial valves thus formed being reflexed. 

 Seeds many, minute, favose-reticulate and glandular. 



1. M. pilosa(Benth.), Greene. Annual, 6 15 in. high, much branched 

 from the base, erect, leafy, villous with long viscid hairs, and with the 

 odor of narcotic solanaceous plants: leaves lanceolate to oblong-ovate, 

 entire, sessile: calyx slender-pedicelled, oblique, the upper segment 

 longest and about equalling the tube: corolla light yellow, 3 4 lines 

 long, little exceeding the calyx. Gravelly banks and shores of mountain 

 streams. June Oct. 



11. HERPESTIS, Gsertn.f. Ours a large herb creeping in mud, or 

 a floating aquatic. Leaves opposite, entire. Flowers axillary. Calyx 

 of 5 distinct very unequal sepals. Corolla campanulate. Stamens 4, 

 in slightly unequal pairs; anther-cells parallel. Capsule thin, 2-valved, 

 the valves 2-parted. Seeds many, elongated. 



1. H. Eiseui (Kell.). Branches prostrate, rooting, ^2 ft. long, 

 stoutish and succulent: leaves oblong-obovate, 1 in. long, sessile, entire, 

 several-nerved from the base: pedicels 1 or 2 in the axils, about as long 

 as the leaves, pubescent: 3 outer sepals broad, the others narrow: 

 corolla white, campanulate, 45 lines wide and as long, with a barely 

 perceptible irregularity, the 2 upper lobes a trifle smaller and nearer 

 together: anthers cordate-ovate, deep blue: seeds linear-oblong. Stag- 

 nant pools along the lower San Joaquin and southward; certainly 

 altogether distinct from H. rolundifolia to which it has been referred. 



12. GRA.TIOLA, Dodoens. Low branching annuals, with opposite 

 sessile leaves, and small solitary flowers on naked axillary peduncles. 

 Calyx 5-parted; the divisions subequal. Small yellowish or white 

 corolla with upper lip entire or 2-lobed; lower 3-cleft; all the lobes 

 spreading. Stamens not exserted, only 2 fertile; their anthers with 2 

 transverse cells on a broad connective; anterior pair either wanting, or 

 represented by sterile filaments. Style usually bent at tip; stigma of 2 

 flat lobes. Capsule many-seeded, 4-valved, the valves parting from the 

 thick axial placenta.
