POLEMONIACEZR. (PoLEMOoNIUM FAMILY.) 
Herbs with alternate or opposite leaves, regular 5-merous and 5-an- 
drous flowers, corolla-lobes convolute in bud, 3-celled ovary and 3-lobed 
style, and a 3-celled 3-valved loculicidal few to many-seeded pod, the 
valves usually breaking away from the triangular center column. 
1. Phlox. Corolla salverform: calyx narrow: leaves mostly opposite, entire. 
29. Gilia. Corolla tubular-funnelform or salverform to campanulate or rotate: 
calyx narrow, partly searious; leaves mostly alternate, entire or variously divided, 
1. PHLOX L. 
Annuals or perennials, with opposite (alternate in no. 4) and sessile 
perfectly entire leaves (the floral often alternate), cymose flowers in 
open terminal or crowded axillary clusters, narrow somewhat prismatic 
or plaited and angled calyx, salverform corolla with long tube, included 
stamens very unequally inserted in the corolla-tube, and ovoid pod with 
sometimes 2 ovules but ripening only a single seed in each cell. 
1. P. pilosa L. Herbaceous perennial: stems slender, nearly erect, 3 to 5 dm. high, 
usually hairy, as are the lanceolate or linear leaves (2.5 to 10 em. long), which com- 
monly taper to a sharp point: cymes at length open: calyx-teeth slender awl-shaped 
andawn-like, longer than the tube, loose or spreading: lobes of the pink-purple or rose- 
red (rarely white) corolla obovate, entire.—Extending into Texas from the Atlantic 
region. In the Gulf region and extending into Texas is var, DETONSA Gray, which 
is a smoother or almost glabrous plant, with corymb and calyx more or less pubescent. 
2 P. nana Nutt. Glandular and roughish-pubescent, low and loosely and 
copiously branching from a somewhat woody base: leaves linear (2.5 to 5 em. long): 
flowers scattered or somewhat corymbose: calyx-tube cylindraceous, the thin-mem- 
branous portion between the ribs not projecting into salient angles: corolla rose, 
“red,” or “ white,” with tube exceeding the calyx; the ample and broadly cuneate- 
obovate or roundish lobes entire or nearly so.—Western borders of Texas. 
3. P. Drummondii Hook. Annual, loosely branching, villous and glandular: 
leaves mostly oblong or lanceolate, mucronate-pointed ; the upper commonly half- 
clasping by a broader somewhat cordate base: flowers mostly in crowded cymose 
clusters: calyx-lobes lanceolate-subulate, soon recurved; corolla red, varying to 
rose, purple, or white; lobes broadly obovate, entire or nearly so, about 12 mm. long: 
tube usually pubescent: ovules solitary in the cells.--Throughout Texas, especially in 
the eastern part, and everywhere caltivated. Along the Nueces occurs var, VILLOSIS- 
sma Gray, a very villous and viscous form, with more scattered flowers of large 
size; while common in eastern Texas is var, TENUIS Gray, a small and slender much 
less pubescent form, with mostly linear and almost glabrous leaves, and lobes of the 
pink or purple corolla only 4 to 8 mim, long. 
4. P, Reemeriana Scheele. Annual, loosely branched from the base, sparsely hir- 
sute or glabrate: leaves lanceolate, or the oblong or spatulate lower ones often gla- 
brous except the margins: flowers solitary or sparse: calyx-lobes linear: corolla pink 
or rose-colored: the glabrous tube not exceeding the calyx, shorter than the ample 
roundish obovate entire lobes; ovules in each cell 4 or 5,—High prairies, southern 
and western Texas. Commonly with most of the leaves alternate, 
2. GILIA Ruiz & Pav. 
Elerbs or a few suffruticose, with narrow and acute calyx-lobes and 
tube scarious below the sinuses, corolla from salverform or funnel-
