Fruit that may be source of honey in Spain (9)
I believe the answer is:
nectarine
'fruit' is the definition.
(nectarine is a kind of fruit)
'source of honey in spain' is the wordplay.
'source of honey' becomes 'nectar' (I've seen this before).
'spain' becomes 'e' (abbreviation for Espana).
'nectar'+'in'+'e'='NECTARINE'
'that may be' acts as a link.
(Other definitions for nectarine that I've seen before include "Fruit - aren't nice (anag)" , "type of tree" , "Kind of peach with thin skin and no down" , "Smooth-skinned fruit" , "Smooth-skinned variety of peach" .)
