Root composed of several club-shaped fleshy tubers. Stems or scapes 4-8 inches high, 

 commonlj' several from one root. Radical leaves on long slender petioles ; cauline ones 1-3, 

 verticillate, sessile, trifoliolate ; leaflets petiolulate, roundish, obtusely 3 - 5-lobed. Pedun- 

 cles 3-6, one-flowered, 1-2 inches long. Flowers nearly an inch in diameter, the central 

 one (the first that expands) conmioidy larger than the others. Sepals 6 - 10, elliptical, white, 

 sometimes shghtly tinged with purple, twice as long as the stamens. Filaments filiform, or 

 somewhat clavate : anthers oblong. Ovaries 6-10: stj^Ie none: stigma simple. Carpels 

 oblong, acute, prominently ribbed, slightly stipitate. 



Common in most parts of the State, in open woods, but rather scarce in the western coun- 

 ties. It begins to flower in the latter part of April, and continues till June. Although so 

 strongly resembling Anemone in its flower, the fruit shows that its true place is in the genus 

 Thalictrum.
