182 MEMOIRS FROM THE DEPARTMENT OF BOTANY OF COLUMBIA UNIVERSITY 



long or narrowly obovate, 1-3 cm. long, crenate, the lateral ones only slightly oblique. 

 Runners few and short. Scape few-flowered, generally about .5 cm. long, silky-strigose, 

 seldom leafy-bracteate. Flowers 1-1.5 cm. in diameter ; bractlets and sepals lanceolate; 

 petals obovate, exceeding the sepals by about a half 



It is nearest related to the preceding, from which it differs in the smaller size, in the 

 thicker leaves, which are puberulent as well as silky beneath, and by the few and short 

 runners. In habit it resembles somewhat F. Mexicana, but differs in the pubescence and 

 the pitted fruit. It seems to be a rather rare plant of limited range. The following 

 specimens have been examined. 



South Dakota: (Black Hills) Rydberg, No. 661, 1892 (type). 



Wyoyning: (Jackson's Hole) Dr. F. V. Hayden, 1860. 



Colorado: (Pike's Peak) F. H. Knowlton, No. 5, 1896. 



i6. Fragaria Terrae-novae. 



?Fragaria Virginiana Hook. Fl. Bor. Am. 1: 185. 1833. 



Rootstock short but not very thick. Leaves rather thin, glabrate above, slightly 

 silky beneath; petioles rather slender, 3-15 cm. long, appressed-silky when young, gen- 

 erally nearly glabrous in age, very rarely with somewhat spreading pubescence ; leaflets 

 2-5 cm. long, obovate, serrate, the lateral ones slightly oblique at the base, all subsessile. 

 Runners few and slender. Scape slender, at first silky-strigose, glabrate in age, few-flow- 

 ered, generally without a foliaceous bract. Flowers 1.5-2 cm. in diameter; sepals and 

 bracts lanceolate, acuminate ; petals broadly obovate, often nearly twice the sepals. 

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



This has been included in F. Virginiana, but is easily distinguished from that species 

 by its smaller size, appressed pubescence of the petioles and scapes, the few-flowered 

 scape, the nearly glabrous leaves and subsessile leaflets; it more resembles F. Canadensis, 

 F. pauciflora and F. Americana. From the first it differs by the appressed pubescence on 

 petioles and scapes and by the hemispherical fruit ; from the second in the broader leaf- 

 lets and the non glaucous hue ; and from the last by the more rounded leaflets and the 

 fruit bearing the achenes in pits. It also generally has larger flowers than any of the 

 three species. The species is of northern and quite limited distribution.
