Phlox. POLEMONIACE.E. 131 



H- -H- Sterile shoots from the base creeping or decumbent : leaves comparatively broad, and with 

 the steins and calyx softly more or less viscid-pubescent: pedicels rather slender. 



P. divaricata, L. Stems diffuse or ascending, the sterile shoots decumbent or somewhat 

 creeping and bearing ovate sessile leaves : cauline leaves oblong- or ovate-lanceolate, rather 

 acute : cyme open : calyx-teeth slenderly linear-subulate : lobes of the bluish or lavender- 

 colored (1 to li inches wide) corolla cimeate-obcordate or barely emarginate (Bot. Mag. 

 t. 163, & P. Canadensis, Sweet, Brit. Fl. Gard. t. 221), or not rarely quite entire (var. 

 L'l/ihfimli, Wood. P. tjlutinosa, Buckley in Am. Jour. Sci. xlv. 177, as to specimens, but 

 flowers not "red or scarlet.") Damp woods, W. Canada and New York to Iowa, Florida 

 and Arkansas. Corolla with the sinuses open. Style (always '? ) very short. 



P. reptans, Michx. Stems weak and slender ; the sterile long and prostate or creeping, 

 runner-like, bearing obovate or roundish leaves with narrowed base; the flowering erect, a 

 span or more high, bearing 3 or 4 pairs of oval or oblong mostly obtuse leaves : cyme sim- 

 ple, few-flowered : calyx-teeth linear-subulate : lobes of the purple or violet corolla round- 

 ish, mostly entire, about half the length of the tube. Vent. Malm. t. 107. P. stolonifera, 

 Sims, Bot. Mag. t. 563; Sweet, Brit. Fl. Gard. ser. 2, t. 293. Damp woods of the Alle- 

 ghany region and near it, Pennsylvania to Kentucky and Georgia. Corolla-tube an inch 

 long; style long, the stigmas and some of the stamens often more or less projecting. 



* * * Stems diffuse and branching, slender, low (a span high): flowers scattered or barely 

 cymulose, peduncled; the peduncles often elongated : lobes of the corolla narrowly cuneate and 

 bilid : calyx-lobes subulate-lanceolate : fl. spring. 



P. bifida, Beck. Minutely pubescent: leaves linear (an inch or two long, a line or two 

 wide), glabrate : lobes of the pale violet-purple corolla 2- (rarely 3-) cleft to or below the 

 middle into oblong or nearly linear diverging segments. Am. Jour. Sci. xi. 167 ; Gray, 

 Man. ed. 5, 373. Prairies of Illinois and Missouri. 



P. Stellaria, Gray. Very glabrous: leaves barely somewhat ciliate at base, linear (an 

 inch or two long, a line or more wide), acute, rather rigid: flowers scattered, mostly long- 

 pcduncled : lobes of the " pale blue or almost white " corolla bifid at the apex into barely 

 oblong lobes. Proc. Am. Acad. 1. c. 252. Cliffs of Kentucky River (above Lexington ? ), 

 in fissures of the 7iiost precipitous rocks, Short. S. Illinois, G. If. French, &c. Bases of the 

 filiform and tufted or creeping steins rigid and persistent. 



2. Suffruticulose and creeping-cespitose, evergreen, east of the Mississippi, 

 with mostly crowded and fascicled subulate and rigid leaves: lobes of the corolla 

 at most obcordate : fl. early spring. 



P. SUbulata, L. (GROUND or Moss PIXK.) Depressed, forming broad mats, pubescent, 

 when old glabrate ; leaves squarrose-spreading, ciliate, varying from lanceolate- or subu- 

 late-linear to almost acerose, 4 to 10 lines long : flowers mostly slender-pedicelled : calyx- 

 lobes subulate: lobes of the (pink, purple, or white) corolla obcordate or rarely entire: 

 ovules solitary or in pairs (or rarely 3) in each cell. (Style generally long and ovules 

 solitary.) Jacq. Fragm. t. 44 ; Bot. Mag. t. 411, & t. 415 (as spf(tcra). P. setacea, L., form 

 with slender leaves. P. nivalis, Lodd. Bot, Cab. t. 780; Sweet, Brit. Fl. Gard. 1. 185: style 

 short; and ovules commonly (but not always) 2 or rarely 3 in each cell, and corolla white. 

 P. Hentzii, Nutt., a state of the last with lobes of the corolla entire or nearly so. P. aris- 

 tata, Lodd. I.e. 1. 1731, a white-flowered variety. Rocky bare hills and sandy banks, 

 S. New York to Michigan, Kentucky and Florida. Very variable species. 

 P. PROCUMBENS, Lehm. (Ind. Sem. Hamb. 1828; Sweet, Brit. Fl. Gard. ser. 2, t. 7 ; Lodd. 



Cab. t. 1722 ; P. subulata, var. latifolia, Benth. in DC. 1. c.), is unknown as a wild plant, and 



is apparently a hybrid between P. subulata and P. amaena. 



3. Suffruticulose or suffrutescent, rarely herbaceous to the ground, natives of 

 the Rocky Mountain region and westward, chiefly with narrow or minute and 

 thickish-margined leaves, and branches or peduncles mostly one-flowered, in 

 spring and summer. (Species most difficult, passing into one another.) 



* Densely cespitose and depressed, mostly forming cushion-like evergreen mats or tufts ; the short 

 leaves (l to 5 lines long) crowded up to the solitary and sessile (or in the last species short-pe- 

 duncled) flowers, and also fascicled, scarious-connate at base, the old ones marcescent: ovules 

 solitary in each cell. The earlier species of the series most depressed, pulvinate, and imbricate- 

 leaved ; the last looser, longer-leaved and approaching the next subsection.
