384 THE KINDS OF PLANTS 



of the lobes: corolla bell-shape, 5-cleft, usually convoluted in bud and 

 bearing 5 folds or scales inside the tube: stjie and stamens (with hairy 

 filaments) projecting. 



H. macrophyllum, Nutt. A hoary-hairy plant, about 1 ft. tall, branching: 

 leaves pinnately cut: flower-cluster on long stout peduncle: corolla white 

 or bluish, about 1 in. across: sepals not appendaged at base: stamens longer 

 than corolla. 



H. appendicuUtum, Michx. Hairy, 1-1 J^ ft. tall: leaves large, mostly 

 5-lobed or angled, some of the lower ones pinnately parted: flower clusters 

 loose: corolla blue: sepals appendaged at bases, bristly hairy: stamens not 

 much if any longer than corolla. 



H. Canad6nse, Linn. About 1 ft. high, smoothish: leaves all rounded, 

 with 5-9 shallow lobes, and heart-shaped bases, or with small leaflets on the 

 petioles: corolla white or purplish. 



XL. POLEMONIACE^. Phlox Family. 



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

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

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

 capsule 3-celled, with 3, mostly loeulicidal, 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. PoJeynonium 



\. PHL6X. Fig. 218. 



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. paniculita, 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. macul^ta, 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. divaric&ta, Linn. Ascending or diffuse to 1 ft., or more, terminating 

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