356 POLEMONIACE.fc. (I'OLEMONIUM FAMILY.) 



* * * Stems low, diffuse and branching ; flowers scattered or barely cymulose; 

 corolla-lobes narrowly cuneate, bifid ; calyx-lobes subulate-lanceolate. 



9. P. bifida, Beck. Minutely pubescent ; stems ascending, branched (5-8' 

 high) ; leaves linear, becoming nearly glabrous (- 1|' long, !" wide) ; flow- 

 ers few, on slender peduncles ; calyx-teeth awl-shaped, about as long as the tube ; 

 lobes of the pale purple corolla 2-c/eft to or below the middle (4" long), equal- 

 ling the tube, the divisions linear-oblong. Prairies of Ind. to loM'a and Mo. 



10. P. Stellaria, Gray. Very glabrous; leaves barely somewhat ciliate 

 at base, linear (1 -2' long, 1" wide or more), acute, rather rigid ; flowers scat- 

 tered, mostly long-peduucled ; lobes of the pale blue or almost u-hite corolla bifid 

 at the apex into barely oblong lobes. Cliffs of Ky. River (Short), S. 111., and 

 Tenn. ( Gattinger). May. 



2. Svffruticulose and creeping-cespitose, erergreen, with mostly crowded and 

 fascicled subulate and rigid leaves. 



11. P. subulata, L. (GROUND or Moss PINK.) Depressed, in broad 

 mats, pubescent (glabrate when old) ; leaves awl-shaped, lanceolate, or nar- 

 rowly 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. GILIA, 



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-glom- 

 erate 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. linearis, 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. 



3. POLEMONIUM, Touru. GREEK VALERIAN. 



Calyx bell-shaped, herbaceous. Stamens equally inserted at the summit of 

 the very short tube of the open-bell-shaped or short funnel-form corolla ; fila- 

 ments slender, declined, hairy-appendaged at the base. Capsule few -several- 

 seeded. Perennials, with alternate pinnate leaves, the upper leaflets some- 

 times confluent; the (blue or white) corymbose flowers nearly braetless. (An 

 ancient name, from iro'Ae/xos, war, of doubtful application.) 



1. P. reptans, L. Smooth throughout or slightly pubescent; stems 

 weak and spreading (6-10' high, never creeping as the name denotes) ; leaf- 

 lets 5-15, ovate-lanceolate or oblong ; corymbs few-flowered ; flowers nodding ; 

 calyx-lobes ovate, shorter than the tube ; stamens and style included; corolla 

 light blue, about V wide ; capsules about 3-seeded. Woods, N. Y. to Minn., 

 south to Ala. and Mo. May, June.
