Can anyone help me identify this leguminous tree growing in hardiness zone 5a (Montreal, Canada)
It produced fruits in late summer/autumn (september/october); numerous hard, dry, dark reddish brown pods containing 2-4 seeds, very similar to the fruit of Erythrophleum Suaveolens. It is also somewhat similar to Balizia peeicellari.
Inside the pod is a greenish membrane with a texture and smell reminiscent of the "honey locust" Gleditsia triacanthos fruit.
The fruits are staying firmly attached on the branch all through winter.
I managed to knock some fruit from the 10 meter high tree today. Here is a picture of the fruits (in casse you can't see the image above): http://www.pinterest.com/pin/444378688203864491/
Alternatively you can try googlemaps; it's the first tree on the corner of that median strip when you spin the camera towards the right http://goo.gl/maps/iuias
What could this tree be?
