Leaf Leaf (l[=e]f), n.; pl. {Leaves} (l[=e]vz). [OE. leef, lef, leaf, AS. le['a]f; akin to S. l[=o]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.

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. [1913 Webster]

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. [1913 Webster]

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. [1913 Webster]

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. [1913 Webster]
