 ward to the Rocky mountains. April, May. If 'Stem, 68 

 inches high. Flowers white varying to purple. Leaves narrow

2. A. lancifolia Pursh : leaves petioled, ternate ; leafets lanceolate, 

 crenate, dentate ; sepals 5, ovate, acute ; fruit ovate ; style short, 

 uncinate. 



HAB. High mountains. Penn. and Virg. May, July. If. Re- 

 sembles the foregoing species, but the flowers are larger and clear 

 white. Pursh. De Candolle who has examined Pursh's plant 

 in the herbarium of Lambert, thinks it scarcely distinct from the

 doubt to A. nemorosa. 



3. A. pennsylranica Unn. : leaves 3-parted ; segments 3-cleft ; lobes

 June, July. It. Stew a foot high. Flowers white, large. By 

 some botanists . 1 . dichotoma of Linneus, is considered distinct 

 from the above, but it is most probably identical with it.
