416 THE KINDS OF PLANTS 



XL. POLEMONIACE.E. Phlox Family. 



Herbs, mostly annuals or perennials: flowers regular, in terminal 

 clusters, 5-parted, with corolla monopetalous; stamens on corolla- 

 tube, alternate with lobes; ovary 3-celled; style simple and 3-lobed: 

 capsule 3-celled, with 3, mostly loculicidal, valves. About 200 species 

 in several genera. Phlox is the leading genus. 



a. Leaves entire, mostly opposite: stamens unequally in- 

 serted on tube of the corolla 1. Phlox 



aa. Leaves pinnately compound, alternate: stamens equally 



inserted on the corolla-tube 2. Polemonium 



1. PHLOX. Fig. 241. 



Erect or diffuse herbs, stems leafy: leaves without stipules, entire, 

 mostly sessile, opposite, or alternate above: flowers of different colors, in 

 terminal clusters; corolla salver-form, tube long; stamens 5, unequal, 

 included in tube. P. Drummondii is annual; the others perennial. 



P. paniculata. Linn. Stems 2-4 ft. high, usually stout and in clumps: 

 leaves ovate-lanceolate, or oblong: flowers on short pedicels in many-flow- 

 ered panicled cymes, terminal, white to various pinks and reds; calyx-teeth 

 sharp-pointed; lobes of corolla rounded and entire. 



P. maculata, Linn. One to 2 ft. high: stem spotted with purple: lower 

 leaves the heavier, lanceolate-linear; upper taper-pointed with a heart- 

 shaped sessile base: panicle elongated, pyramidal, of many pink-purple 

 flowers; calyx-teeth less pointed than in preceding: corolla-lobes entire. 

 All summer. This and the preceding species are the originals of the common 

 perennial phloxes of gardens. 



P. divaricata, Linn. Ascending or diffuse to 1 ft., or more, terminating 

 in loose corymb, rather sticky -pubescent: leaves ovate-oblong or broad-lan- 

 ceolate, rounded at base, acute at tip, sessile, pubescent: corolla large, gray- 

 ish blue or lilac, the lobes notched; calyx-teeth slender and longer than 

 tube. Moist woods. Spring. 



P. subulata, Linn. Ground or moss pink. Stems creeping, tufted, much 

 branched and leafy, forming a moss-like carpet over the ground: leaves 

 about y$ in. long, rigid, linear to awl-shaped, spreading in clusters: flowers 

 3-6 in depressed clusters, white to pinkish-purple; lobes of corolla shorter 

 than tube. Spring. 



P. Drummondii, Hook. From Texas, now the common annual phlox in 

 gardens: stems branching, spreading, about 1 ft. high, rather downy-clammy: 

 flowers showy, in corymbs; various colors and patterns on the corolla and 

 lobes variously notched. 



2. POLEMONIUM. 



Perennial herbs, with alternate pinnately compound leaves: calyx com- 

 panulate, segments erect over fruit; corolla bell-form or rotate; stamens
