=Fraxinus Pennsylvanica, var. lanceolata, Sarg.=

_Fraxinus viridis, Michx. f. Fraxinus lanceolata, Borkh._

GREEN ASH.

River valleys and wet woods.

Ontario to Saskatchewan.

Maine,--common along the Penobscot river from Oldtown to Bangor;
Vermont,--along Lake Champlain; Gardner's island, and the north end of
South Hero; Rhode Island (Bailey); Connecticut,--frequent (J. N. Bishop,
_Report of Connecticut Board of Agriculture_, 1895).

South along the mountains to Florida; west to the Rocky mountains.

The claims to specific distinction rest mainly upon the usual absence of
pubescence from the young shoots, leaves and petioles, the color of the
leaves (which is bright green above and scarcely less so beneath), the
usually more distinct serratures above the center, and a rather more
acuminate apex.

Apparently an extreme form of _F. pubescens_, connected with it by
numerous intermediate forms through the entire range of the species.

BLACK ASH. SWAMP ASH. BASKET ASH. HOOP ASH. BROWN ASH.

=Habitat and Range.=--Wet woods, river bottoms, and swamps.

Anticosti through Ontario.

Maine,--common; New Hampshire,--south of the White mountains;
Vermont,--common; Massachusetts,--more common in central and western
sections; Rhode Island,--infrequent; Connecticut,--occasional
throughout.

South to Delaware and Virginia; west to Arkansas and Missouri.

=Habit.=--A tall tree reaching a height of 60-80 feet, with a trunk
diameter of 1-2 feet; attaining greater dimensions southward. In swamps,
when shut in by other trees, the trunk is straight, very slender,
scarcely tapering to point of branching, in open situations under
favorable conditions forming a large, round, open head. Easily
distinguished from the other ashes by its sessile leaflets.

=Bark.=--Bark of trunk a soft ash-gray, in old trees marked by parallel
ridges separating into fine, thin, close flakes
