  1. \Leaf\, n.; pl. {Leaves}. [OE. leef, lef, leaf, AS.
    le['a]f; akin to S. l?f, OFries. laf, D. loof foliage, G.
    laub,OHG. loub leaf, foliage, Icel. lauf, Sw. l["o]f, Dan.
    l["o]v, Goth. laufs; cf. Lith. lapas. Cf. {Lodge}.]
    1. (Bot.) A colored, usually green, expansion growing from
       the side of a stem or rootstock, in which the sap for the
       use of the plant is elaborated under the influence of
       light; one of the parts of a plant which collectively
       constitute its foliage.
    Note: Such leaves usually consist of a blade, or lamina,
          supported upon a leafstalk or petiole, which, continued
          through the blade as the midrib, gives off woody ribs
          and veins that support the cellular texture. The
          petiole has usually some sort of an appendage on each
          side of its base, which is called the stipule. The
          green parenchyma of the leaf is covered with a thin
          epiderm pierced with closable microscopic openings,
          known as stomata.
    2. (Bot.) A special organ of vegetation in the form of a
       lateral outgrowth from the stem, whether appearing as a
       part of the foliage, or as a cotyledon, a scale, a bract,
       a spine, or a tendril.
    Note: In this view every part of a plant, except the root and
          the stem, is either a leaf, or is composed of leaves
          more or less modified and transformed.
    3. Something which is like a leaf in being wide and thin and
