Description
Large, deciduous ash trees, Fraxinus excelsior, that grow throughout the temperate regions of Europe. Varieties include F. excelsior latifolia (weeping ash) and F.excelsior Diversifolia. European ash trees have a dense wood that is tough and elastic with a straight grain and slightly coarse texture. It is moderately durable but susceptible to insect attack. The timber is used for ladders, tool handles, oars, poles, wheels, boats, weapons, furniture, gymnasium equipment, tennis racquets, and hockey sticks.
Synonyms and Related Terms
European ash (Fraxinus excelsior); weeping ash (F. excelsior latifolia); Almindelig Ask (Dan.); Gemeine Esche (Deut.); frêne (Fr.); es (Ned.); ask (Sven.); fresno (Esp.); freixo europeu (Port.); frassino (It.)
Other Properties
Tall tree growing to 35 m. Bark=gray; new buds are black Leaves=compound with 9-13 leaflets with toal length of 20-35 cm. Fruit=group of winged samara with long narrow seed.
| Density | 40-53 ppcf |

Paper fiber type: hardwood, ring porous. Using transmitted light microscopy, pulp is identified by vessels with two distinct sizes. Vessels have profuse, small pitting. Perforations are simple. Tyloses and pointed, irregularly shaped vasocentric trachieds are present. Appearance with Graff "C" stain: dark blue, but varies with bleaching. Average dimensions of fibers: length, 0.9mm. 22μm wide. Common pulping method: kraft.
