ROSE FAMILY. Rosaceae. 
There are many kinds of Cinquefoils, mostly natives 
of the north temperate zone, usually herbs, with compound - 
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 
into a dry, seed-like akene. Potentilla means “‘ powerful,’’ 
as some sorts are medicinal. They often resemble Butter- 
cups, but never have shiny petals, and Buttercups do not 
have bractlets between the calyx-lobes. |
