The leaves are simply toothed and opposite. The twig has a pair of
opposite leaves, then a second pair perpendicular to the first, then a
third pair aligned as the first pair and so on. What is such an
The flat, long fruit, shown in pic-2, looks somewhat like a smaller
version of green-ash fruit.

From what little I know:
Fraxinus Americana is White Ash. Green Ash is Fraxinus Pennsylvanica.
Nevertheless, while the Ash has opposite leaf-pairs, adjacent
alternate leaf-pairs are not perpendicular to each other. The ash
leaf-pairs are all in the same plane. In my photos you may be able to
notice that adjacent pairs of leaves twisted on the twig by 90
Can you show me some online images of the leaves that show the leaves
the way I have described them? Or please point me to a book.
I think you are both pretty close. I, too, believe it is an ash, most
likely Fraxinus oxycarpa (or F. angustifolia ssp. oxycarpa, if you prefer)
if the leaf pairs are whorled. I agree with Toad - the fruit is hard to

I am adding the newsgroup sci/bio/botany to the thread. Toad and Pam
are suggesting the tree is a Fraxinus Oxycarpa (Raywood Ash). Pictures
of Raywood Ash show the leaf-pairs in a single plane while the tree in
my photos have adjacent leaf-pairs perpendicular to each other. Please

More likely, you're looking at the leaflets making up a compound leaf
typical of most ash species. Yours has simple leaves.

The fruits in your photo very clearly seem to be those of an ash [genus
Fraxinus], but nearly all ashes have compound leaves divided into leaflets.
Your tree, on the other hand, seems to have simple, toothed leaves. I'd
thought that the only simple-leaved ash species was _Fraxinus anomala_
from the southwest, but its foliage appears rather different from yours:

[European Ash] has simple leaves. That's my best guess as to the
identity of your mystery tree.
I remember that Fraxinus angustifolia 'Monophylla' also has simple leaves
(compound leaves with a single leaflet). As can be read from the name this
is a fairly old cultivar. Its leaves will be rather more narrow.

1) ash has leaflets
2) according to my dendrology text the leaflets of F.angustifolia
'Monophylla' are twice the size of F.angustifolia and actually bigger than
those of a typical F.excelsior
3) I never suggested that this is the identity of the 'mystery tree'
