nut tree

I'm a little stuck... Click here to teach me more about this clue!

'hazel' is the definition.
(I've seen this before)

I don't understand how the rest of the clue works.

(Other definitions for nut tree that I've seen before include "source of fruit" , "Hazel's one" , "the ultimate reason, the rhymster said, for visit by Spanish princess" , "Eg, almond/hazel/etc" , "Eg, almond or hazel" .)

I've seen this clue in the Irish Times.
