The buds are of a deep blue, and the young shoots are
sprinkled with dots of the same colour, which disappear as the
season advances. Theleaves, at their unfolding, are accompanied
by scales, which fail after two or three weeks: they are 12 or
15 inches long when fully developed ; and the leaflets are sessile,
ot a deep green colour, smooth on the upper surface, and coated
with red down on the main ribs l>eneath. When bruised they
emit an odour like tiiat of the leaves of the elder. Tiie s i
maras resemble those of the blue ash (F quadrangulata) and
are nearly as broad at the base as at the summit. The black
ash IS easily distinguished from the white ash by its bark,
which IS of a ( uller hue, less deeply furrowed, and has the
layers of the epidermis applied in broad sheets

The leaflets are large, smooth, oval-

by short petiolules. The young
shoots to which the leaves ai'e attached

The green ash is easily
recognised by the brilliant
colour of its young shoots ;
and by its leaves being nearly
of the same colour on both
surfaces. From this uniform-
ity, which is rarely observed
in the foliage of trees. Dr.

name concolor ; and Michaux

with from 2 to 4 pairs of leaflets, and an odd one, according to the
vigour of the tree, and to the coolness of the soil in which it grows. The
leaflets are petiolated, and distinctly denticulated. The seeds are small ; and
the tree does not attain a great size. There is a splendid specimen 70 it.
