[+] Filaments broad and short; nutlets dull, wrinkled or roughish when dry.
2. M. paniculàta, Don. Roughish and more or less hairy, erect (1–2° high), loosely branched, leaves ovate and ovate-lanceolate, taper-pointed, ribbed, thin; corolla (6´´ long) somewhat funnel-form, 3–4 times the length of the lance-linear acute divisions of the calyx, filaments broader and shorter than the anthers.—Shore of L. Superior and north and westward. July and Aug.
3. M. lanceolàta, DC. Glabrous or hirsute, pale, 1° high or less, simple or branched, leaves spatulate-oblong to lanceolate-linear, smaller (1–2´ long), nearly veinless, obtuse or acute; corolla-tube somewhat longer than the lanceolate calyx-lobes; filaments generally longer than the anthers.—Dak. to N. Mex. and westward.
[+][+] Filaments longer and narrower than the anthers; nutlets shining, utricular.
4. M. marítima, Don. (Sea Lungwort.) Spreading or decumbent, smooth, glaucous; leaves fleshy, ovate or obovate or spatulate, the upper surface becoming papillose; corolla white, bell-funnel-form (3´´ long), twice the length of the calyx.—Sea-coast, on rocks and sand, Cape Cod to Maine and northward; scarce. June–Aug.
6. MYOSÒTIS, Dill. Scorpion-grass. Forget-me-not.
Corolla salver-form, the tube about the length of the 5-toothed or 5-cleft calyx, the throat with 5 small and blunt arching appendages opposite the rounded lobes; the latter convolute in the bud! Stamens included, on very short filaments. Nutlets smooth, compressed, fixed at the base; the scar minute.—Low and mostly soft-hairy herbs, with entire leaves, those of the stem sessile, and with small flowers in naked racemes, which are entirely bractless, or occasionally with one or two small leaves next the base, prolonged and straightened in fruit. Flowering through the season. (Name composed of μύς, mouse, and οὖς, ὠτός, ear, in allusion to the aspect of the short and soft leaves in some species; one popular name is Mouse-ear.)
[*] Calyx open in fruit, its hairs appressed, none of them hooked or glandular.
M. palústris, Withering. (True Forget-me-not.) Perennial; stems ascending from an oblique creeping base (9–20´ high), loosely branched, smoothish; leaves rough-pubescent, oblong-lanceolate or linear-oblong; calyx-lobes much shorter than its tube; limb of corolla 3 or 4 lines broad, sky-blue with a yellow eye.—In wet ground, probably only escaped from cultivation. (Nat. from Eu.)
1. M. láxa, Lehm. Perennial from filiform subterranean shoots; stems very slender, decumbent; pubescence all appressed; leaves lanceolate-oblong or somewhat spatulate; calyx-lobes as long as its tube; limb of corolla 2 or 3´´ broad, paler blue. (M. palustris, var. laxa, Gray.)—In water and wet ground, Newf. to N. Y. (Eu.)
