Flower arranger's willow

Can anyone recognise and name the following willow please? Every internet search comes up with the contorted willow but this one is totally different. Thin straight green stems, alternate green leaves which curl around the stem in a very snail-like fashon. Unfortunately the flower arranger who used it could only call it Curly Willow and the piece she gave me has lost all its leaves so no nice picture. Placed in water I can see the start of rootlets so may have a plant in the end but would love to name it!!

Thank you so very much, that's brilliant!
