ROSE FAMILY. Rosaceae. 



There are many kinds of Cinquefoils, mostly natives 

 of the north temperate zone, usually herbs, with compound j 

 leaves and yellow, white or purple flowers, always with 

 pedicels; the flat or cup-shaped calyx, with five, main 

 teeth, alternating with five, tooth-like bractlets; petals 

 five, broad, often notched; stamens numerous, with thread- 

 like filaments and small anthers, near the base of the calyx- 

 cup; pistils numerous, on the conical, hairy receptacle, 

 which does not become fleshy or juicy, each pistil maturing j 

 into a dry, seed-like akene. Potentilla means "powerful/'j 

 as some sorts are medicinal. They often resemble B utter- 1 

 cups, but never have shiny petals, and Buttercups do not 

 have bractlets between the calyx-lobes.
