486 POLEMONIACEJS. Phlox. 



1. PHLOX, Linn. 



Calyx narrow, 5-cleft. Corolla salverform, with a narrow orifice and broad or 



rounded lobes. Stamens included, very unequally inserted on the upper part of the 



tube : filaments usually very short. Ovules and seeds solitary in each cell (or the 



former sometimes 2 or 3). Capsule small, ovoid. Seed with a simple and close 



coat, neither mucilaginous nor developing spiral threads when wet. — Herbaceous 



or suffruticose plants (ours all perennial), with simple and entire opposite leaves, or 



the uppermost alternate, and rather showy terminal or cyrnose flowers ; the corolla 



white, purple, &c, in all the Californian white or light rose-color. 



A genus of nearly 30 species, all North American and one Siberian, several of them familiar in 

 ornamental cultivation. The Pacific species are few, and different from those of the Atlantic States. 



* Loose; with flowering branches mainly herbaceous from a tvoody base: leaves linear 

 or lanceolate, spreading, mostly an inch or two long : flowers peduncled and loosely 

 cymose-clustered. 



1. P. speciosa, Pursh. A T iscid-puberulent above or nearly glabrous : flowering 

 stems a foot to a yard high, diffusely ascending from a branching woody base: leaves 

 lanceolate or linear, one or two inches long, the upper broader at the base : flowers 

 corymbose, showy : lobes of the corolla obcordate ot sometimes merely emarginate, 

 a third to half an inch long ; the tube little exceeding the calyx : style not longer 

 than the ovary nor the stigmas. — Gray, Proc. Am. Acad. viii. 256. P. Sabini, 

 Dough, a northern form with almost entire corolla-lobes. P. occidentalis, Durand 

 in Pacif. E. Eep. iv. 125. P. divaricata, Durand, PL Pratten, in Jour. Acad. Philad. 

 n. ser. ii. 97. 



In the Sierra Nevada and its foot-hills, Placer to Plumas Co., and northward to the borders 

 of British Columbia ; chiefly the larger and broader-leaved form. 



2. P. longifolia, ISTutt. Somewhat viscid-pubescent or glabrous : tufted stems 

 about a span high from a woody base : leaves narrowly linear and an inch or two 

 long in the typical forms : flowers smaller : lobes of the corolla obovate or oblong- 

 cuneate, entire or refuse, a fourth to a third of an inch long ; the tube considerably 

 longer than the angled calyx: style long and slender. — Jour. Acad. Philad. vii. 41 ; 

 Gray, 1. c. P. humilis, Dougl. in DC. Prodr. ix. 306. 



Var. Stansburyi, Gray, 1. c. A rather dwarf and rigid form, more pubescent, 

 with lanceolate or ovate-lanceolate leaves, sometimes of about half an inch in length; 

 appearing very distinct, but it passes into the genuine form. — P. speciosa, var. 

 Stansburyi, Torr. Bot. Mex. Bound. 145. 



Eastern part of the Sierra Nevada, from near Carson City and Sierra Valley {Anderson, Lemmon, 

 &c.), thence far eastward and northward through the interior regions to and beyond the Eocky 

 Mountains. 



* * Cespitose and dejiressed, forming broad or dense matted tufts : flowers sessile, 



terminating the densely leafy branches. 

 +- Leaves acerose or subulate, rigid or loose, green, destitute of cobwebby hairs. 



3. P. Douglasii, Hook. Forming broad but rather open tufts, glabrous or a 

 little pubescent : leaves acerose, commonly spreading, half an inch or less in length, 

 and with fascicled shorter ones crowded in the axils, their margins naked or nearly 

 so: tube of the corolla longer than the calyx; the lobes obovate and entire, about 3 

 lines long. — Fl. ii. 73, t. 158. 



Var. diffusa, Gray, 1. c. : a form of moister or more shaded stations, with pro- 

 cumbent stems, and laxer less rigid leaves. — P. diffusa, Benth. PL Hartw. 325. 



Var. longifolia, Gray, 1. c. : a form with more slender and rigid leaves, from 

 half to two thirds of an inch in length.
