Acer

A twig of some sort of acer/maple with a ton of samaras.
Samara is a new word for me. It's the name of such a fruit.
On the samara on the right is a small white curved hair. Exactly like the hair of our dog, Omo. (2. extra)
Maybe it was on my clothes and flew on it.
Question towards the extra: Does anyone know what happend to the focus in the middle of the flower? It looks kind of weird.
