Willow identification - help needed

Hello,
Can anyone tell me if this is Crack Willow or Almond Willow and if so - how can you tell the difference.
Thanks!

 

In addition to vegetative characters willows are told apart by their flowers
and fruits.

 

The leaves are too broad for Crack Willow, and lack Almond Willow's characteristic stipules, so neither of them. Have to wait for the flowers and fruit . . .
