 the lobes acute, broadly oblong, dentate or crenate; those of 

 the involucre similar, sessile; flower solitary, 9" broad,

 Virginia. Readily distinguishable from the European 

 A. nemorosa L., which is sometimes cultivated in our 

 area and reported as escaped in Massachusetts, by its 

 slender habit, slender petioles, less lobed divisions of the 

 involucral leaves, paler green foliage, more slender root- 

 stocks, and smaller flowers. Wood-flower. May-flower.
