apex obtuse ; upper leaves sessile, clasping, sometimes perfoliate 

 at the inflorescence. Flowers racemose on pedicels much longer 

 than the bracts, erect, spreading. Calyx papery, enlarging in 

 age, the upper tooth longer than the others which are folded 

 under. The calyx resembles a fist with the index finger pointing. 

 Corolla yellow, varying greatly in size, sometimes spotted with 

 brown, lower lip 3-lobed, longer than the 3-lobed upper. Capsule 

 elliptical, included in the calyx. Those plants which grow where 

 the soil is rich and moist become tall and luxuriant, with large 

 flowers ; those with small flowers are probably half starved. The 

 peculiar calyx will always distinguish this species. Kings River 

 Caiion, Millwood. 



Mimulus acutidens Qreene. Stems slender, almost smooth, 

 angled, branching. Lowest leaves inch long, oblong, on short 

 petioles, upper ovate sessile by a broad base, entire or sharply 

 toothed. Pedicels thread-like, longer than the leaves, spreading, 

 angled. Calj-x wedge-shaped at base, pubescent, % inch long, 

 keeled ribs, teeth equal, spreading, broadly deltoid, acuminate. 

 Corolla rose-color, with the tube almost twice as long as the calj^x, 

 widening upwards, border ample, the lobes about equal. Capsule 

 linear-oblong, included in the papery calyx, not a line wide. 

 Millwood. 



Mimulus floribundus Dougl. Annual, much branched chiefly 

 from the base with weak, slender stems, viscid, pubescent and 

 woolly, a few inches to-a foot high. Leaves small, ovate, about Yz 

 inch long, on short petioles, entire or sharply toothed. Flow^ers 

 in all the axils on slender spreading pedicels surpassing the leaves. 

 Cah-x wing-angled, papery, teeth short, deltoid, equal. Corolla 

 yellow, the tube as long as the calyx, the border of 5 almost equal 

 roundish divisions. Stamens included. After the corolla falls 

 the style is noticeablj' longer than the calyx, which is sometimes 

 dotted and enlarged in fruit. Bubbs Creek, Millw-ood. 



Mimulus montiQides Qray. Low, slender, erect annual, sim- 

 ple or branched, glandular puberulent. Leaves linear, narrow, 

 about an inch long. Pedicels thread-like, longer or shorter than 

 the leaves, becoming almost perpendicular to the stem and hold- 

 ing the erect fruiting calyx like candelabra. Calyx tubular, 

 elongating in fruit, ribs not keeled, teeth very short, broad, equal, 

 mucronate, ciliate. Corolla yellow, twice as long as the calyx, 

 half inch or more, tube funnel-form, exserted, border ample, 

 spreading, with lobes about equal, lower lip bearded, upper hairy 

 on the inside. Capsule included in the calyx, oblong-elliptical % 

 inch long. This beautiful species grows in General Grant Park
