8. P. divaricàta, L. Stems spreading or ascending from a decumbent base (9–18´ high); leaves oblong- or lance-ovate or the lower oblong-lanceolate (1½´ long), acutish; cyme corymbose-panicled, spreading, loosely-flowered; calyx-teeth slender awl-shaped, longer than the tube; lobes of the pale lilac or bluish corolla obcordate or wedge-obovate and notched at the end, or often entire, ½-{2/3}´ long, equalling or longer than the tube, with rather wide sinuses between them.—Rocky damp woods, W. Canada and N. Y. to Minn., south to Fla. and Ark. May.—A form occurs near Crawfordsville, Ind., with reduced flowers, the narrow entire acuminate corolla-lobes scarcely half as long as the tube.
[*][*][*] Stems low, diffuse and branching; flowers scattered or barely cymulose; corolla-lobes narrowly cuneate, bifid; calyx-lobes subulate-lanceolate.
9. P. bífida, Beck. Minutely pubescent; stems ascending, branched (5–8´ high); leaves linear, becoming nearly glabrous (½–1½´ long, 1½´´ wide); flowers few, on slender peduncles; calyx-teeth awl-shaped, about as long as the tube; lobes of the pale purple corolla 2-cleft to or below the middle (4´´ long), equalling the tube, the divisions linear-oblong.—Prairies of Ind. to Iowa and Mo.
10. P. Stellària, Gray. Very glabrous; leaves barely somewhat ciliate at base, linear (1–2´ long, 1´´ wide or more), acute, rather rigid; flowers scattered, mostly long-peduncled; lobes of the pale blue or almost white corolla bifid at the apex into barely oblong lobes.—Cliffs of Ky. River (Short), S. Ill., and Tenn. (Gattinger). May.
§ 2. Suffruticulose and creeping-cespitose, evergreen, with mostly crowded and fascicled subulate and rigid leaves.
11. P. subulàta, L. (Ground or Moss Pink.) Depressed, in broad mats, pubescent (glabrate when old); leaves awl-shaped, lanceolate, or narrowly linear (3–6´´ long); cymes few-flowered; calyx-teeth awl-shaped, rigid; corolla pink-purple or rose-color with a darker centre (sometimes white); lobes wedge-shaped, notched, rarely entire.—Dry rocky hills and sandy banks, southern N. Y. to Mich., south to Fla. and Ky.
2. GÍLIA, Ruiz & Pav.
Calyx-lobes narrow and acute, the tube scarious below the sinuses. Corolla tubular-funnel-form or salver-form. Stamens equally or unequally inserted. Capsule with solitary to numerous seeds.—Mostly herbs with alternate leaves. Our species belongs to the § Collomia, in which the flowers are capitate-glomerate and foliose-bracted or scattered, stamens unequally inserted in the narrow tube of the salver-form corolla, ovules solitary, and leaves sessile and entire; annuals. (Dedicated to Philip Gil, a Spanish botanist.)
1. G. lineàris, Gray. Branching and in age spreading, 6–18´ high; leaves linear- or oblong-lanceolate; calyx-lobes triangular-lanceolate, acute; corolla 6´´ long, from lilac-purple to nearly white, very slender, with small limb. (Collomia linearis, Nutt.)—From Minn. west to the Pacific.
