Rootstock short but not thick. Leaves very thin, very soon glabrate on both sides ; 
— 
petioles slender, 5-10 cm. long, sparingly silky, with less spreading hairs than in 
the related species, or glabrate; leaflets 5-8 cm. long, rhombic-obovate, mostly acute, 
sharply and deeply serrate, the lateral ones oblique at the base. Runners very slender 
and long. Scape slender, seldom over 1.5 dm. long, sparingly silky with slightly spread- 
ing or sometimes divaricate hairs, seldom much exceeding the leaves, very rarely leafy- 
bracteate. Fruit elongated-ovoid, .5-.75 cm. in diameter and 1-1.5 em. long, red; 
achenes superficial. 
It is, next to / Virginiana, our most common strawberry, extending from New- 
foundland and Virginia to New Mexico. It has been confounded with F. vesca, but 
differs in the thinner and sharper-toothed leaves, elongated fruit, slender habit, and 
finer, scantier and more appressed pubescence.
