The wood is not commercially distinguished from the white ash, but its mechanical properties rank it somewhat below that species.[70] [Illustration: Plate 126. FRAXINUS LANCEOLATA Borkhausen. Green Ash. (× 1/2.)] =3. Fraxinus lanceolàta= Borckhausen. White Ash. Green Ash. Swamp Ash. Plate 126. Medium to large sized trees with fissured bark, the ridges and furrows narrower than those of the white ash; twigs slender and glabrous at maturity; leaves generally 2-3 dm. long, rachis smooth, rarely slightly pubescent; leaflets 5-9, usually 7, generally 5-15 cm. long, on stalks generally about 0.5 cm. or less in length, the terminal one on a stalk 2-4 times as long, leaflets generally narrow-oblong or ovate to narrow ovate-oblong, generally with a narrowed base, sometimes rounded and oblique, short or long acuminate at apex, margin entire near the base, the remainder of the margin generally sparsely serrate with short teeth, dark green and smooth above, a lighter green beneath and more or less pubescent on the petiolules, midrib and veins; calyx persistent, about 1 mm. long; fruit ripens in September and October, linear or spatulate, 3-5 cm. long, variable in size and shape, body 1/3-1/2 the length of samara, compressed or flattened and gradually narrowed to the base, usually less than half as wide as the wing, each face of the body usually striated with about 2-4 lines which are stronger than those near the edge of the body; wing generally 5-6 mm. wide, pointed or notched at apex, and decurrent on the sides of the body for about one-half of its length. =Distribution.=--Lake Champlain to the Saskatchewan and south to the Gulf. Found in all parts of Indiana. It is usually found in low ground along streams, in swamps, and in low woods. It is usually associated with white elm, red maple, cottonwood, aspens, linn, bur oak, etc., in the south to this list should be added silver maple and cypress. It prefers a habitat wetter than that of the white ash, although the two are found together in wet woods. In swampy woods it is often a common tree. While it has a general distribution in the State, it is much more local than the white ash. =Remarks.=--This form is not usually separated from the next species, and both are known in books and by nurserymen as green or red ash. The common name, green ash, should be applied to this species to separate it from the true white ash, and the next. In ash forest plantings on the Clark County State Forest, it is to be noted that this and the next species bear fruit while the trees are as small as 1.5 cm. in diameter, while the white and Biltmore ash which are much older and 6-8 cm. in diameter have never borne fruit. This species and the next bear fruit oftener and in greater abundance than the white or Biltmore ash. It is also to be noted that practically all of the volunteer ash trees found along fences and roadsides, except very large trees, are of the green ash species.
