356 POLEMONIACEJE. (POLEMONIUM 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 ; items ascending, branched (5 - 8' 

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

 ers 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), equal- 

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



1 0. 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-peduncled ; lobes of the pale blue or almost white corolla bijid 

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

 Tenn. (Gattinger). May. 



2. Suffruticulose and creeping -cespitose, evergreen, 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,

2. GILIA, 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 Collomm, 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, Tourn. 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 bractless. (An 

 ancient name, from ir6\fjLos, war, of doubtful application.) 



1. P. r6ptans, 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 \' wide; capsules about ^-seeded. Woods, N. Y. to Minn.,
