Tree seed identification

young codger

I have an idea of the tree species that these seeds came from.

I would say the small one is Sycamore. I am not sure about the large one but it could be Field Maple?

Anyone else know better?

Difficult to say, but you are probably right with the Sycamore.  The second one could be Norway Maple.

Yes I was looking at Field & Norway maple. I couldn't arrive  at a definitive answer.

At this time of year while the trees still have leaves it should be a little easier.

1.Acer campestre....field maple....the fruit is called samara with two winged achenes aligned at 180°......see link...

2. Acer platanoides...common name Norway maple.
Quote wiki....

 "The fruit is a double samara with two winged seeds. the seeds are disc-shaped, strongly flattened, 10–15 mm (3⁄8–5⁄8 in) across and 3 mm (1⁄8 in) thick. The wings are 3–5 cm (1 1⁄4–2 in) long, widely spread, approaching a 180° angle"

@Silver surfer
Thanks for your efforts. The Sycamore seeds were picked from the tree.

 The ongoing uncertainty concerns the maples. They were not picked  from a tree. They were collected from the gutter by the kerb.

Available photos tend to show the Samaras in their "fresh" state. The ones I collected had time to lose pigment & distort  somewhat as they became dry in the hot weather. This makes identification more difficult.

Today managed to find Acer campestre...field maple.
Hope this helps.
