The expanded, leafy portion of a leaf or frond, which can be one entire unbroken leaf (simple) or a highly dissected and divided leaf (compound).

The newly hatched, earliest stage of any of various animals that undergo metamorphosis, differing markedly in form and appearance from the adult. Caterpillars are the larval form or larvae (pl) of butterflies and moths.

As pertains to stems: borne along a side. A side shoot or bud; typically situated in the axil at a stem node - lateral buds are typically axillary.

A method of propagating a plant in which its stem is induced to send out roots by surrounding a section of it with soil while still attached to a parent plant; natural layering can occur when the stem makes contact with the soil and spontaneous rooting occurs (such as when young trees are pushed over by snow, rock, or soil slides).

The flat and, typically, green part of a plant that constitutes foilage and is responsible for food production through photosynthesis. Needles on certain plants are also leaves.

The base of the leaf, near the petiole. Each plant species has specific characteristics for the leaf base that can help with identification.

The expanded, leafy portion of a leaf or frond, which can be one entire unbroken leaf (simple) or a highly dissected and divided leaf (compound). Each plant species has specific characteristics for the leaf blade that can help with identification.

The area on the outside of a grass leaf where the leaf blade meets the leaf sheath. Each grass species has specific characteristics for the leaf collar that can help with identification.

The edge of the leaf blade/lamina. Each plant species has specific characteristics for the leaf margin that can help with identification.

An imprint or scar left on stem tissue at the separation/breaking off of the leaf petiole from the plant stem/branch. Left once a leaf drops off from the stem of a plant.

The leaf base that surrounds the grass stem/culm and is attached to the upper leaf blade/lamina. Each grass species has specific characteristics for the leaf sheath that can help with identification.

A dry, several-seeded fruit that has developed from one flower having a single-celled ovary, and splits open along two seams at maturity (such as peas, beans); often a long pod. Mostly dehiscent, but some species being slowly-dehiscent, with a few species' fruits being indehiscent.

In grasses, the lower bract which, with the palea (upper bract), encloses a flower's/floret's reproductive organs. Each grass species has specific characteristics for the lemma that can help with identification.

A slightly raised, often lens-shaped area on a stem surface that allows exchange of gases.

The series of stages through which a living thing passes from the beginning of its life until its death.

A tongue or strap-shaped organ; in grasses and some sedges, an appendage that arises from the inner surface of a grass leaf where the blade/lamina meets the leaf sheath, thus it is inside of where the collar region is located on the leaf. Each grass species has specific characteristics for the ligule that can help with identification.

A dehiscent legume, several-seeded fruit that has developed from one flower, which narrows/constricts and is jointed between its seeds, drying and splitting apart at maturity into one-seeded segments, each having two seams.
