K08E FAMILY. 123 



P. apg^ntea, Silvert C. Dry fields, banks, and roadsides N. ; a low, 

 spreading or prostrate, much branched, white-woolly weed, with wedge-oblong 

 cut-pinnatifid leaflets green above, white with silvery wool beneath, and the 

 margins revolute ; the small flowers somewhat panicled, all summer. 



* » Leaves pinnate : receptacle and partly the akenes wliite-hairy. 



P. Anserlna, Silver-Weed. Wet banks and shores, N. & W. : leaves 

 all from the root or in tufts on tlio long slender runners, green above, silvery 

 with silky down_ beneath, of 9-19 oblong cut-toothed principal leaflets and 

 some pairs of minute ones intei-mixed; stipules conspicuous and many-cleft; 

 flowers solitary on long scape-like peduncles, all summer. 



P. fruticosa, Shrobby C. Wet grounds N. : 2° - 4° high, woody, silky, 

 very much branched, with 5 or 7 crowded oblong-lanceolate entire leaflets^ 

 scale-like stipules, and loose clusters of rather showy flowers, all summer. 



§ 4. Petals white : akenes and receptacle hairy : leaflets only 3, digitate. ^ 

 P. trident&ta, Three-toothed C. Coast of N. England N. and on 

 mountains : 4' - 6' high, tufted, spreading, with 3 thickish nearly smooth leaflets 

 coarsely 3-toothed at the end, and several flowers in a cyme, in early summer. 

 § 5. Petals purple, rose-color, or crimson : akenes smooth, y. 

 * Wild in wet and cold bogs N. : petals narrow, shorter than the calyx. 

 P. pallistris, Marsh Five-finger. Stems ascending from an almost 

 woody creeping base ; leaves pinnate, of 5 - 7 lance-oblong serrate and crowded 

 leaflets, whitish beneath; flowers in a small cyme, the calyx nearly. 1' broad, 

 the inside as well as the petals dull dark purple ; receptacle becoming large and 

 spongy : fl. all summer. 



« » Prom Himalaya, cult, for ornament : petals broad and large, obcordate. 



P. Nepal^nsis, Nepal C. Leaflets 3 in the upper, 5 in the lowest leaves, 

 digitate, hairy but green both sides, wedge-oblong, coarsely toothed ; flowers 

 rose-red, all summer. P. HopwoodiXna, with flesh-colored flowers, is a gar- 

 den hybrid of this and P. recta. 



P. atrosanguinea. Dark Nepal C, is soft silky-hairy, with 3 leaflets 

 to all the leaves, and much darker-colored flowers than in the preceding, brown- 

 purple or crimson. 



8. PRAGARIA, STRAWBERRY. (Name from fraga, the old Latin 

 name of the strawberry. ) 21 



§ 1. True Strawberries. Petalswhite: rec^ade of the fruit high-flavored : 

 scapes several-flowered : runners naked. PL in spring and early summer, 

 those of all but the first species inclined more or less to be dicecious. In 

 cultivation the ■'species are considerably mixed by crossing. 



P. V^SCa, Common S. of Europe, yields the Alpine, Perpetual, &c., 

 plentifully native N. ; is mostly slender, with thin dull leaflets strongly marked 

 by the veins, calyx remaining open or reflexed after flowering, small ovoid- 

 conical or elongated fruit high-scented, and the akenes superficial. 



P. el^tior, Haijtbois S., of Europe, sometimes cult. ; is taller and quite 

 dioecious, with the calyx strongly reflexed away from the fruit, which is dull 

 reddish and musky-scented. 



P. Virginidina, Virginian Wild S., original of the American Scar- 

 let, &c. ; has leaflets of flrm texture, their smooth and often shining upper 

 surface with sunken veins, calyx becoming erect after flowering and closing 

 over the hairy receptacle when unfructified ; fruit with a narrow neck, mostly 

 globular, its surface with deep pits in which the akenes are sunken. 



Var. IUino6nsis, perhaps a distinct species, is coarser and larger, grows in 

 richer soil, from W. New York W. & S., the hairs of the scape, &c. shaggy, is 

 the supposed original of Hovey's Seedling, Boston Pine, &c. 



P. Chil^nsis, native of Pacific coast from Oregon S. ; its varieties and 

 crosses with the foregoing have given rise to the Pine-apple S. and the like : 

 a large and robust species, with very firm and thick leaflets soft-silky beneath or 

 on both faces, and a hairy receptacle, the large rose-colored fruit erect in the 

 pure state (instead of hanging), ripening late.
