Foliation
Definition:
(n.) The process of forming into a leaf or leaves.
(n.) The manner in which the young leaves are dispo/ed within the bud.
(n.) The act of beating a metal into a thin plate, leaf, foil, or lamina.
(n.) The act of coating with an amalgam of tin foil and quicksilver, as in making looking-glasses.
