There are many, many willows with wide leaves. I just went out in the yard and took these pics:
Salix cinerarea and S. cinerarea 'Variegata'
Salix chaenomeloides
Salix gracilistyla 'Melanostachys' and S. schraderiana
Although those (above) are Eurasian willows, there are many American ones with wide leaves, too.
Salix candida
I guess I don't have a pic of Salix repens foliage
Salix repens 'Iona Form'
I've never had any galls on my willows, but they are common in the wild here.
