Paper fiber type: softwood, soft pine. Using transmitted light microscopy, fibers are identified by the presence of egg-shaped fenestriform pits 2-3 across the fiber. Pits are uniform in size and occur mostly commonly in groups of two. Appearance with Graff "C" stain: varies with pulping and bleaching. Ray tracheids are non-dentate. Average dimensions of fibers: length 5.9mm, width 40-50μm. Common pulping method: Common pulping method: kraft and sulfite.
