Rootstock short and thick, crowned with rather numerous leaves and large, scarious 

 brown stipules 1-2 cm. long. Petioles 2-20 cm. long, stout, brownish, rather densely 

 silky, with appressed or ascending, seldom spreading hairs. Leaves very thick and 

 coriaceous, brownish when mature, slightly silky above when young, but perfectly gla- 

 brous in age, strongly nerved and reticulated, densely silky-strigose and finely tomen- 

 tulose beneath ; terminal leaflet evidently petiolate, broadly obovate, truncate, sub-ob- 

 cordate or sometimes rounded at the apex and crenate above the middle, with the terminal 

 tooth generally much smaller, 2-5 cm. long; lateral leaflets similar, but somewhat smaller, 

 short-petiolate or subsessile and very oblique at the base ; runners strong, often .5 m. 

 long ; scape in the common form generally low, less than 1 dm. high, branched near the 

 base and withouta leafy bract, always densely silky-strigose. Flowers 2-3.5 cm. in diameter. 

 Hypanthium, sepals and braetlets silky-strigose ; bractlets and sepals oblong or lanceolate, 

 acute or acuminate. Petals broadly obovate, exceeding the sepals by about a half. 

 Fruit hemispheric, 1.5-2 cm. in diameter, quite hairy ; achenes nearly superficial, set in 

 shallow pits. 



F. Chiloeasis is distinguished from all American strawberries by the very thick and 

 strongly reticulated leaves and from all except the next species by tlie size of the floAvers. 

 It is a native of the Pacific slope of America, extending from Alaska to Patagonia ; it 

 is also found on the Sandwich Islands and is cultivated in many parts of the world.
