MEMOIRS FROM THE DEPARTMENT OF BOTANY OF COLUMBIA UNIVERSITY 177 



Eootstoek short and thick, nearly erect. Leaves thin, glabrate above, silky beneath ; 

 stipules ovate, scarious ; petioles 2-5 cm. long, slightly silky with spreading hairs ; termi- 

 nal leaflet broadly obovate, truncate, coarsely 3-7-toothed at the apex, 1-2 cm. long ; 

 lateral ones somewhat smaller, oblique at the base. Runners long and slender, rather 

 numerous. Scape short, few-flowered, with rather scanty spreading silky hairs. Sepals 

 and bractlets broadly lanceolate, acute, otherwise resembling those of the following. 

 Fruit unknown. 



It is evidently nearly related to the next species, differing mainly in the acute sepals, 

 the few-toothed leaves and larger terminal leaflet. The smaller leaves, especially those 

 of the plantlets formed by the runners, much resemble those of Sibbaldia 'procumhens L.

ID. Fragaria truncata. 



Rootstock short and thick. Leaves rather few, thin, silky on both sides, but in age 

 glabrate above ; stipules oblong or ovate, brown, scarious ; petioles slender, 2-8 cm. long, 

 sparingly silky with long spreading hairs ; leaflets petiolate, rounded-obovate, round- 

 crenate above the middle, with the middle tooth smaller, 1.5-4 cm. long, the lateral ones 

 very little oblique. Scape slender, few-flowered, seldom exceeding 1 dm. in height, and 

 rarely leafy-bracteate, sparingly silky with spreading hairs. Flowers 1-2 cm. in diameter. 

 Hypanthium, bractlets and sepals sparingly and flnely silky ; bractlets and sepals oblong 

 or ovate, obtuse or acutish. Petals obovate, exceeding the sepals by about a third. Fruit 

 unknown. 



As the fruit is unknown to the author the place of this species is uncertain. If the 

 achenes are in pits, i. e., the species belongs to the present group, its place is next 

 to F. platypetala, from which it is easily distinguished by its broad sepals and bractlets, 

 its few-flowered scape, narrower petals and sparser and shorter pubescence. It also seems 

 to have some relationship to F. Chiloensis and F. Californica, the form of the leaves 

 resembling most that of the former, while the texture is that of the latter, as is also the 

 pubescence, although sparser.
