MEMOIRS FROM THE DEPARTMENT OF BOTANY OF COLUMBIA UNIVERSITY 175 
F. vesca, but the differences are so trifling, that they do not warrant making it a species. 
It is not related to the native Ff Americana.

Rootstock very short and rather thick. Leaves very thin, somewhat glaucous, silky 
when young, glabrate in age, especially on the upper surface ; petioles slender, 3-10 cm. 
long, silky with long white spreading or reflexed hairs; Jeaflets broadly rhombic-obo- 
vate, coarsely toothed, 2-5 cm. long, the lateral ones very oblique. Runners very slen- 
der, rather few. ‘Scape often over 1 dm. high, often exceeding the leaves, silky with long 
and spreading or reflexed hairs, often with a unifoliolate leafy bract, 2-8-flowered. Flowers 
1.5-2 em. in diameter; sepals and bracts lanceolate, acute; petals rounded obovate, often 
nearly twice the length of the sepals. Fruit apparently somewhat elongated, ovoid or 
sem1-ellipsoid, red, about .75 cm. in diameter and 1 em. long; achenes superficial. 
It is nearest related to F. vesca and F. Americana, differing from the former in the 
thinner leaves, the more slender habit and elongated fruit, and from the latter in the 
leafy bract, the larger flowers with spreading sepals, and the less sharply serrate and 
rounder leaflets. It represents /. Americana on the Pacific slope, but the ranges of the 
two overlap in the Rockies.
