The Silver-weed creeps along the ground by means of 

 slender many-jointed runners, and its stems are usually 

 curved and winding. When the fruit ripens it consists of a

P. arguta, or Tall Cinquefoil, is a handsome plant, with 

 coarse pinnate leaves, the terminal one being wedge-shaped 

 and three-cleft at the top, and has small white flowers growing

 yellow flowers that grow in rather close leafy clusters. 



P. Hippiaiia, or Woolly Cinquefoil, is a stout plant, with
