Garden-Patience, or Monk's Rhubarb

Descript : This is a Dock bearing the name of Rhubarb for some purging quality therein, and grows up with large tall stalks, set with somewhat broad and long, fair, green leaves, not dented at all. The tops of the stalks being divided into many small branches, bear reddish or purplish flowers, and three- square seed, like unto other Docks. The root is long, great and yellow, like unto the wild Docks, but a little redder; and if it be a little dried, shews less store of discoloured veins than the other does when it is dry.
