POLEMONIACE^. ' Phlox. 



1. PHLOX, Linn. 



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

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

 the ui)permost alternate, and rather showy terminal or cymose 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; vnth fmvering brandies mainly herbaceous from a woody base: leaves linear 

 or lanceolate, spreading, mostly an inch or two long : Jiowers pediincled and loosely 

 cymose-cliistered. 



1. P. speciosa, Pursh. Yiscid-puberulent above or nearly glabrous : flowering 

 stems a foot to a yard high, dift'usely 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 or 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. 2.56. F. Sahini, 

 Dougl., a northern form Avith almost entire corolla-lobes. P. occideutaUs, Durand

 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, Xutt. Somewhat viscid-pubescent or glabrous : tufted stems 

 about a span high from a woody base : leaves nan-owly linear and an inch or two 

 long in the tj'pical forms : flowers smaller : lobes of the corolla obovate or oblong- 

 cuifeate, 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. Jnunl/is, Dougl. in DC. Prodr. ix. 306. 



Yar. Stansburyi, Ciray, 1. c. A rather dwarf and rigid form, more pubescent, 

 Avith 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 CJarson City and Sierra Valley (Anderson, Lemmon, 

 kc), thence far eastward and northward through the interior regions to and beyond the Kocky 

 Mountains. 



* >!: Cesjntose and depressed, forming broad or dense matted tufts : Jiowers sessile, 



terminating the densely leafy branches. 



-i- 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 Avith 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. — ri. ii. 73, t. 158. 



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

 cuinbcnt stems, aii.l laxer less rigid leaves. —P. diffusa, Benth. PL HartAV. 325. 



\m\ longifolia, Gray, 1. c. : a form Avith more slender and rigid leaves, from
