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

the stem, is either a leaf, or is composed of leaves
more or less modified and transformed.
