Phlox. POLEMONIACE^. 133 



* Loosely tufted or many-stemmed from a merelj' woody-persistent base, or wholly herbaceous, 

 with linear or lanceolate (or rarely ovate) spreading (approximate or sometimes distant) leaves, 

 which are little if at all fascicled in the axils : flowers slender-pedaucled, solitary or somewhat 

 cymulose. 



•i— Style long and slender, often equalling or almost equalling the tube of the corolla. 

 ■H- Arctic, with rather flaccid leaves and stems. 

 P. Sibirica L. Mostly villous-pubescent, especially on the margins of the narrow linear 

 leaves, depressed and loosely cespitose, less than a span high : tube of the corolla little 

 longer than its obcordate or eniarginate lobes, seldom surpassing the calyx : ovules 2 in 

 each cell. — (Gmel. Fl. Sib. iv. t. 40, fig. 2.) Trautv. Imag. t. 24. — Kotzebue Sound. (N. 

 E. Asia.) 



++ ++ Temperate, inhabiting the plains and mountains from the borders of British Columbia south- 

 ward : leaves and commoniy erect or ascending stems more firm or rigid : calyx-tube between the 

 strong ribs scarious, inclined to be membranaceous and more or less replicate, forming intervening 

 angles : the narrowly sul)ulate and mostly rigid teeth shorter than the tube of the rose-colored 

 or sometimes white corolla. 



P. linearifolia, Gray. Glabrous, above sometimes minutely hirsute-pubescent, corym- 

 bosely much branched from a ligneous base, a span or more high : leaves very narrowly 

 linear (an inch or two long, about a line wide) : caly.x-tube mostly saliently 5-angled from 

 the broader base by the strong replication of the white-membranaceous sinuses ; the lobes 

 nearly acerose : tube of the corolla little exceeding the calyx ; tiie obovate-cuneate lobes 

 entire or barely refuse : ovules 2 in each cell. — P. speciosa, var. linearifolia, Hook. Kew.

P. longifolia, Nutt. Nearly glabrous or pubescent, much branched or many-stemmed 

 from a ligneous base, 3 to 8 inches high : calyx more or less angled by the white-mem- 

 branaceous replicate sinuses : leaves mostly narrowly linear (1 to 2|- inches long) : lobes of 

 the corolla obovate- or oblong-cuneate, entire or refuse : ovules almost always solitary in 

 each cell. — Jour. Acad. Philad. vii. 41. P. speciosa, var.. Hook. Fl. ii. 72. P. luimilis,

Var. Stansburyi, Gray, 1. c. Conspicuously pubescent throughout, or sometimes 

 glabrate, generally stouter and more open in growth : leaves from linear to linear-lanceo- 

 late : pubescence of the branches and calyx viscid or glandular ; corolla mostly pink or 

 rose-color, and its tube commonly twice the length of the calyx ; the lobes emarginate or 

 erose at the apex : ovules sometimes a pair in one or two of the cells. — P. speciosa, var. 1

Var. brevif olia, Gray, 1. c, a depressed or dwarf form ; with leaves 9 to 4 lines long, 

 rigid and with more cartilaginous margins, at least the lower lanceolate or ovate-lanceo- 

 late: peduncles either short or none, or elongated. — From Dakotah (Black Hills) to N. 

 California and Arizona. 



P. adsurgens, Torr. Glabrous, except the slender peduncles and scarcely replicate- 

 angled calyx, which are glandular-pubescent : stems diffuse and ascending, slender (a span 

 or two long) : leaves ovate-lanceolate and ovate, acute, 5 to 10 lines long, all but the lower 

 much shorter than the internodes : tube of the corolla nearly twice the length of the 

 calyx; its lobes obovate, entire (about 5 lines long) : ovules solitary in each cell. — Gray,

-t— -t^ Style very short, mostly shorter than the ovary and the linear stic^mas : calyx-tube cylin- 

 draceous, the thin-membranous portion between the ribs not projecting into salient angles. 



P. speciosa, Pursh. Above somewhat viscid-puberulcnt or glandular, below often gla- 

 brous, a foot to even a yard high ; the branches ascending from a slirubby base : leaves 

 lanceolate or linear (an inch or two long) ; the upper especially broadest at base: flowers 

 corymbose : corolla rose-pink or nearly white ; its t\ibe little exceeding the calyx ; its 

 lobes obcordate: ovules solitary. — Gray, Proc. I.e. & Bot. Calif, i. 486. P. speciosa, vav.
