Description
A medium sized deciduous tree, such as Nyssa sylvatica and Nyssa aquatica, native to the eastern United States. Tupelo trees produce a stiff, tough wood that is hard to split. It is used for pallets, baskets, boxes, veneer, barrels and firewood. Tupelo bark dye has good washfastness and fair lightfastness.
Synonyms and Related Terms
black gum (Nyssa sylvatica); sour gum; pepperidge; beetlebung; water tupelo (Nyssa aquatica)
Other Properties
Medium sized tree growing to 25 m. Bark=grayish brown with shallow, irregular furrows. Leaf=simple alternate, pinnately veined oval (3-5 inches long) with coarse teeth, turning an intense red/purple color in fall.. Fruit = purple drupe (1 cm) ripening in late summer.

Paper fiber type: hardwood, diffuse porous. Using transmitted light microscopy, pulp is identified by long vessels with profuse opposite pitting. Spirals may be present on tips. Perforations are scalariform with >15 bars. Appearance with Graff "C" stain: dark blue, but varies with bleaching. Average dimensions of fibers: length, 1.8mm. 20-32μm wide. Common pulping method: kraft.
