Mimulus. SCROPHULARIACE.E. 569 



with calyx-teeth as long in proportion as those of M. bicolor. In the dehiscence of the meni- 

 branaceous capsule the placenta sometimes splits into two portions adnate to the valves, but as 

 commonly is barely 2-cleft at the summit. The whole plant is often purplish. 



+- +- Leafy-stemmed, viscidly villous or pilose : leaves all petioled, thin and broad, 

 toothed, more or less jnnnately veined : corolla yellow : calyx slightly if at all 

 oblique. 



20. M. floribundus, Dougl. Annual, erect or with numerous ascending 

 branches, a span or two high, flowering from the base : leaves ovate (half to a full 

 inch long), the lower slightly cordate : upper peduncles longer than the leaves : 

 calyx short cam panulate, becoming ovate in fruit (barely a quarter of an inch 

 long) ; the teeth short, equal, broadly triangular : corolla barely half an inch long : 

 capsule globose-ovate, obtuse. Lindl. Bot. Reg. t. 1125. 



Moist ground, throughout the Sierra Nevada region (Biyelow, Lemmon, Rothrock) ; thence to 

 Oregon and the Rocky Mountains. 



21. M. moschatus, Dougl. Annual, or perennial by the creeping stems, diffuse 

 and decumbent, beset with very soft long hairs, strongly musk-scented : leaves ovate 

 or oblong, short-petioled (an inch or two long), mostly exceeding the peduncles : 

 calyx short-prismatic, oblong-cam panulate in fruit (a third of an inch long) ; the 

 teeth somewhat unequal, rather long, acuminate : corolla two thirds to a full inch 

 long : capsule ovate, acute. Lindl. Bot. Reg. t. 1118. 



Wet and muddy ground ; common in the mountains, especially northward, extending to 

 British Columbia, and eastward to Utah. The Californian specimens of this, the Musk-plant of 

 the gardens, incline to have a longer corolla, fully thrice the length of the calyx, and twice the 

 size of that of the plant in common cultivation. 



-f- -t- -f- Scapose. 



22. M. primuloid.es, Benth. Perennial by stolons, dwarf : leaves sessile, from 

 broadly obovate to linear-oblong, entire or toothed, 3 5-nerved, obtuse (a quarter 

 to a full inch long), all crowded in a radical tuft at the base of the filiform (1 to 3 

 inches long) scape, or, in large and vigorous plants, in several approximate pairs 

 on a stem which is as long as the one or two peduncles (1 to 4 inches) : calyx 

 narrow (in fruit oblong and at most 3 lines long), with short and equal teeth, less 

 than half the length of the funnelform golden yellow corolla. Regel, Gartenfl. 

 1872, t. 739. 



Wet meadows in the Sierra Nevada, from Mount Whitney northward to Oregon, and in 

 Nevada ; only at considerable elevations. Leaves at first villous with long and soft jointed 

 hairs : peduncles and calyx glabrous. Corolla varying from 3 to 8 lines in length. 



5. Corolla, &c., of Mimulus proper : calyx short and 5-cleft, not prismatic nor with 

 carinate angles or lobes : capsule and divided placentce as of the section 

 Eunanus : low annual. MIMULOIDES, Benth. under Herpestis. 



23. M. pilosus, Watson. Annual, a span or more high, much branched from 

 the base, leafy, villous throughout with long and soft white and somewhat viscid 

 hairs, flowering from almost all the axils : leaves lanceolate or almost oblong, entire, 

 sessile, the later ones about the length of the peduncles : calyx oblique, the upper 

 tooth longest and about the length of the tube, all oblong or ovate : corolla yellow, 

 3 or 4 lines long, little exceeding the calyx ; the lips short and with equal lobes, a 

 pair of brown-purple spots on the lower : capsule oblong-ovate, acute. Bot. King 

 Exp. 225. Herpestis (Mimuloides) pilosa, Benth. in Comp. Bot. Mag. ii. 57, & 

 DC. 1. c. 394. Mimulus exilis, Durand, in Pacif. R. Rep. v. 12, t. 12. 



Gravelly banks of streams ; very common, extending into the borders of Nevada. Lobes of 

 the calyx plans and nearly nerveless ; the tube without ribs, a slight inflexion corresponding 

 with the sinuses. The anther-cells are oblong, not "linear." The stigma is bilamellate, as in 

 the genus, not "entire."
