Perennial or biennial hispid or strigose-pubescent herbs, mostly with thick woody roots, alternate or basal narrow leaves, and small white racemose-paniculate or densely thyrsoid flowers. Calyx very deeply 5-parted or 5-divided, the segments lanceolate, more or less spreading or recurved in fruit. Corolla funnelform or salverform, mostly crested in the throat, 5-lobed. Stamens included. Ovary 4-divided; style mostly short. Nutlets 4, laterally attached to the receptacle, not keeled, their margins acute or winged. [Greek, mountain nut.] Called White Forget-me-not.
Inflorescence racemose-paniculate; nutlets smooth.

Perennial, rather stout, branched from the base and sometimes also above, strigose-pubescent or somewhat hirsute, 5'-12' high. Upper leaves linear, 1/2'-1' long, the lower oblanceolate, somewhat longer, obtuse or acute; racemes slender, panicled; pedicels about 1" long; calyx canescent and somewhat hispid, the segments slightly spreading, or erect in fruit; bractlets longer than the fruiting calyx; corolla 11/2"-3" broad; its tube about equalling the calyx; nutlets smooth, nearly 1" long, shining, closely fitting together, triangular, acute-margined, nearly as wide as high.
In dry soil, western Nebraska and Wyoming to Texas and Arizona. May-Aug.

Perennial or biennial, densely hispid; stem erect, stout, simple or branched, 6-18' high. Leaves spatulate or the upper linear, obtuse, 1'-2 1/2' long, the basal commonly tufted; inflorescence of thyrsoid clusters, the short dense lateral spike-like clusters mostly longer than the subtending bracts; calyx densely bristly; corolla 3"-5" broad; fruit pyramidal, the nutlets triangular-ovate, acute, acutely margined, papillose on the back.
In dry soil, Manitoba to Nebraska, New Mexico and Utah. May-Sept.

Perennial, low, tufted from the woody root; stems usually simple, 3'-6' high, silvery appressed-pubescent, or hirsute above. Leaves linear-spatulate, 1/2'-1' long, i"-i1/2" wide, obtuse or acutish, imbricated on the short sterile shoots and at the bases of the flowering stems; inflorescence thyrsoid or glomerate, usually short; calyx densely hispid; corolla 2"-3" broad, its tube not longer than the calyx; style short; nutlets acutely margined, acute, papillose on the back.

Perennial, tufted, similar to the preceding species but densely strigose or hirsute. Leaves spatulate, or oblanceolate, obtuse, the lower and basal ones \'-\\' long; inflorescence of thyrsoid clusters; calyx densely setose with yellowish hairs; corolla about 2" broad, its tube longer than the calyx, 2 or 3 times the length of the lobes; style filiform; nutlets acutely margined, tuberculate on the back.
