M. lewisii var. alba Henry; M. lewisii f. tetonensis (Nels. ) Macb. & Pays.
Perennial from a running rootstock; stems erect, 3-8 dm. tall, usually unbranched, mostly viscid-pubescent, sometimes viscid-villous; leaves thin, oblong-lanceolate to ovate-oblong, 2-8 cm. long, 1-2.5 em. wide, 3-5-nerved from *he base, sessile, entire to irregularly dentate with short blunt teeth; pedicels mostly exceeding the sub- tending leaves. Superficially much like the species of section Erythranthe.
Mostly damp and wet, exposed places, 6000-9100 ft.
Clark, Douglas, Elko, Ormsby, Storey and Washoe Counties.
7. MIMULUS MOSCHATUS Dougl., Bot. Reg. 13, pl. 1118. 1828.
Perennial; rootstocks; stem weak, creeping or decumbent, up to 33 em. long; entire plant viscid-villous and sometimes slimy to the touch; leaves broadly or narrowly ovate, 1-) cm. long, 0.5-2.5 em. wide, acute or obtuse, mostly denticulate, sometimes entire, short- petiolate, pinnately veined; flowers few; pedicels shorter than the subtending leaves.
This plant is perhaps much more variable than is at present indicated. Specimens with equal calyx teeth, different pubescence and with other variations in character have been noted that are either close to or synonymous with this entity. However, in all cases the material was incomplete and no definite conclusions could be drawn.
Damp, wet or rarely dry, open or shaded places.
Douglas, Elko and Washoe Counties.

Very close to M. rubellus Gray but the stigma lobes are clearly different. However, M. breweri (Greene) Coville, M. suksdorfii Gray and M. rubellus Gray present a confusing problem. A rather intensive study (which is beyond the scope of this paper) seems necessary to establish, if possible, the true limits and relationship of these threes taxa, assuming that three taxa do exist.
Dry or wet places, ),000-11,300 ft.
