Description
A general name for several species of pine trees in the US that contain a similar type of strong wood. The tall yellow pines produces a dense, close-grain wood with a high resin content. It expands and contracts with moisture often causing coatings to crack, flake and peel. Yellow pine is used for lumber and millwork.
Synonyms and Related Terms
In Western US: Jeffrey pine (Pinus jeffreyi), Ponderosa pine (Pinus ponderosa)
In Southern US: Longleaf pine (Pinus palustris), Shortleaf pine (Pinus echinata); Loblolly pine (Pinus taeda); southern yellow pine (common name)

Paper fiber type: softwood, hard pine. Using transmitted light microscopy, fibers are identified by the presence of pinoid pits in horizontal groups. Southern yellow pines have more late wood fibers (with thicker walls) than early wood. Dentate ray tracheids are present. Appearance with Graff "C" stain: varies with pulping and bleaching. Average dimensions of fibers: length 4mm, width 45μm. Common pulping method: kraft and sulfite. Very common paper fiber.
