Description

A tall, commonly found pine tree, Pinus mitis, native to North America. Yellow pine 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

Pinus mitus; shortleaf pine; spruce pine; southern yellow pine; pondersosa pine

Other Properties

Density 23-37 ppcf

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.
