Intermountain Flora
Stems 1-several (or even rather numerous) from a fleshy-thickened, rather short taproot, 1-3 (4) dm tall, glabrous or rather sparsely strigose; basal leaves usually wanting; cauline leaves inconspicuously veined, mostly elliptic or narrowly oblong to spatulate or obovate-oblong, obtuse or broadly rounded to sometimes acutish, 2-9 cm long and 0.5-2 (2.5) cm wide, the lower often tapering to an evident petiole, the others sessile or nearly so, glabrous beneath, strigose above, the hairs sometimes directed toward the margins as in M. fusiformis, sometimes directed forward as in M. viridis; inflorescence at first congested, later a little more open; calyx mostly 2.5-4 mm long, cleft to below the middle or near the base, its segments loosely strigose across the back as well as toften ciliate on the margins; corolla-tube short and slender, mostly 2.5-4 mm long and only 1.5-2 mm wide as pressed, from a little shorter to a little longer than the calyx, with or without a ring of haris inside; corolla-limb evidently longer than the tube, widely flaring, mostly 5-8 mm long and 6-11 mm wide; filaments very short, the anthers 1-1.3 mm long (dry), virtually sessile, wholly included within the tube, their tips just reaching the level of the fornices, or occasionally the anthers set a little higher, the bases about at the level of the fornices; style short, mostly 1-2.5 mm long, reaching to near the base or about the middle of the anthers.
