Hawaiian nut (9)
I believe the answer is:
macadamia
'hawaiian nut' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for macadamia that I've seen before include "nut-tree" , "Queensland nut" , "Australian tree with edible nuts - a CIA madam (anag)" , "Nut-bearing tree" , "(Of drug) causing dependency" .)
