Solved Identity of small tree growing in country hedge

Can anyone shed light, please? Next to my house is a small tree in a field hedge. Its leaves are similar in shape to a crabapple but more matt, not shiny and with a slightly greyish underside. The stems are dark brown, appearing black in bright light, so this tree stands out from those alongside it. There don't seem to be any others in a hedge of hornbeam, hawthorn & hazel. (All the h's.) Can't find a definitive ID in my books or online.
Many thanks, lindyco

 

Possibly goat willow.
Salix caprea

 

Thanks Pete, but the Salix Caprea seems to have a more textured leaf.
Also, this tree has no catkins.

Definitely one of the weedy Salix...willows.

 

Catkins are over now.
If it's Male the catkins will be gone, if female they would have shed lots of seed as white fluffy stuff and be falling now.

 

Thanks again, Pete and Silver Surfer. It is indeed Salix Caprea! I've been to have another look and there have been female catkins up high, above where the hedge has been cut. Also the older leaves are more textured. So, question answered. What a wonderful resource GC is!!
Thanks again. Lindyco
