\Rev"o*lute\, a. [L. revolutus, p. p. of revolvere. See
{Revolve}.] (Bot. & Zo["o]l.)
Rolled backward or downward.
Note: A revolute leaf is coiled downwards, with the lower
      surface inside the coil. A leaf with revolute margins
      has the edges rolled under, as in the Andromeda
      polifilia.
