Rootstock thick and short. Leaves moderately thick, or in shaded places rather 

 thin, dark green, not glaucous, slightly silky when young, glabrate in age ; petioles 2-30 

 cm. long, villous with spreading hairs, rather stout; leaflets 3-10 cm. long, obovate or 

 oblong, always petiolate, coarsely toothed, obtuse at the apex. Runners long and rather 

 stout. Scape stout, more or less villous with spreading or, on the pedicels, often ap- 

 pressed hairs, generally 1.5-2 dm. high, but often 4-5 dm. high, often with a foliaceous 

 bract, and rather many-flowered. Flowers 1-2 cm. in diameter ; bractlets and sepals lan- 

 ceolate, acute or acuminate ; petals obovate, generally exceeding the sepals by a half. 

 Fruit 1-1.5 cm. in diameter, hemispheric ; achenes set in pits. 



F. Virginiana is the tallest and stoutest of our native strawberries. It is often culti- 

 vated and has produced several garden varieties. 



In dryer soil, especially in Kansas, Nebraska and Minnesota, it is often only .5 dm. 

 high, with smaller and more crowded leaves. A form from the southern states differs 

 sora.ewhat and may be treated as a variety. So, also, one from the prairie states. F. Vir- 

 giniana has a range extending from Prince Edward Island to Minnesota, Indian Terri- 

 tory and Georgia.
