Phlox. P0LEM0NIACE2E. 131 



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

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



P. divaricata, L. Stems cliff use 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 \\ inches wide) corolla cuneate-obcordate or barely emarginate (Bot. Mag. 

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

 Laphamii, 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, Miohx. 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. FI. 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 

 bifid : 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- 

 peduncled : 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 t ), 

 in fissures of the most precipitous rocks, Short. S. Illinois, G. H. French, &c. Bases of the 

 filiform and tufted or creeping stems 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, Li. (Ground or Moss Pink.) 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 setacea). P.setacea, L., form 

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

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

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

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

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

 P. PROctbiBExs, 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. amama. 



§ 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 cnshion-like evergreen mats or tufts ; the short 

 leaves (1J to 5 lines long) crowded up to the solitary and sessile (or in the last species short-pe- 

 duncled) flowers, and also fascicled, scarious-connat'e 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.
