Latewood - The part of a tree's annual growth ring that is formed later in the season

Lath - A thin, narrow wooden strip, used as a backing for wall plaster or other materials.

Light sap stain - A slight difference in color which will not materially impair the appearance of a piece if given a natural finish.

Lignin - The second most abundant constituent of wood, located principally in the secondary wall and the middle lamella, which is the thin cementing layer between wood cells. Chemically, it is an irregular polymer of substituted propylphenol groups, and thus no simple chemical formula can be written for it.

Linear foot - A measurement of the length of a board in one dimension; this is not the same as a board foot which is a volumetric measurement.

Log - A portion of a trunk (or stem) of a felled tree that has been cleared of branches and made ready for sawing into lumber.

Loosened or raised grain - Consists of a small portion of the wood being loosened or raised but not displaced.

Lumber - A manufactured product derived from a log in a sawmill, or in a sawmill and planing mill, which when rough shall have been sawed, edged and trimmed at least to the extent of showing saw marks in the wood on the four longitudinal surfaces of each piece for its overall length, and which has not been further manufactured other than by cross-cutting, ripping, resawing, joining crosswise and/or endwise in a flat plane, surfacing with or without end matching, and working.

Lumber tally - A record of lumber giving the number of boards or pieces by width, thickness, length, grade and species.
