=Form=.—Height 30-65 feet, diameter 1-3 feet; trunk straight and clear

with many upright branches which form a compact, broad, irregular crown.

=Leaves=.—Opposite, pinnately compound, 10-12 inches long, with 7-9

leaflets 3-5 inches long, oblong-lanceolate, taper-pointed, almost

entire, pale or more or less pubescent.

=Flowers=.—May; dioecious; in downy panicles on shoots of the previous

season.

samaras 1-2 inches long, borne copiously in drooping clusters.

=Bark=.—Twigs usually pubescent, on old trunks rough with scaly dark

gray-brown ridges.

=Notes=.—Red Ash is occasionally found along some of the streams of

the State but does not grow in sufficient quantities to be of any

commercial importance. It can usually be distinguished from the White

Ash by its pubescent twigs and petioles, and its somewhat different

fruits. A variety of this species, _lanceolata_, is also to be found in

some places along the streams.

[Illustration: BLACK ASH]

BLACK ASH

=Fraxinus nigra=, Marsh.

=Form=.—Height 60-90 feet, diameter 1-2 feet; trunk rather slender,

and straight, bearing a narrow-ovoid or rounded crown of upright

and Tucker counties. Reported from Randolph, Webster, Monongalia,

Summers, and Wirt counties.

=Habitat=.—Low river bottoms and swamps.

cannot be considered as an important species. When in leaf it is easily

distinguished from the other Ashes by the leaflets which are sessile on

the main petiole.
