356 POLKMONIACE.*:. (POLEMONIUM PWMILY.) 



* * * Stems low, diffuse and branching ; Jiotcers scattered or hareli/ cymulose; 

 corolla-lobes narrowly cuneate, bijid ; cahjx-lobes subulate-lanceolate. 



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

 high) ; leaves linear, becoming nearly glabrous (^- H' long, H" wide) ; flow- 

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

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

 ling the tube, the divisions linear-oblong. — Prairies of Ind. to Iowa and Mo. 



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

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

 tered, mostly long-peduncled ; lobes of the pale blue or almost ichite corolla bifd 

 at the apex into barely oblong lobes. — Cliffs of Ky. Kiver {Short), S. 111., and 

 Tenn. (Gattinger). May. 



§ 2. Suffruticulose and creeping-cespitose, ei-ergreen, icith mostly crowded and 

 fascicled subulate and rigid leaves. 



11. P. SUbulata, L. (Ground or Moss Pixk.) 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-sliaped, rigid ; 

 corolla piuk-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 Pla. and Ky. 



2. GILIA, Euiz & Pav. 



Calvx-lobes narrow and acute, the tube scarious below the sinuses. Corolla 

 tubular-funnel-form or salver-form. Stamens equally or unequally inserted. 

 Capsu-le 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. Avest to the Pacific. 



3. POLEMONIUM, Tourn. Greek A^aleriax. 



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 bractless. (An 

 ancient name, from iroAefios, war, of doubtful application.) 



1. P. r^ptans, L. Smooth throughout or slightly pubescent; stems 

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

 lets 5-1.5, ovate-lanceolate or oblong ; corymbs feAv-flowered ; flowers nodding ; 

 calyx-lobes ovate, shorter than the tube ; sta7n€ns and style included; corolla 

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

 south to Ala. and Mo. May, June.
