Source of bananas, a blessing for a monkey (6)

I believe the answer is:

baboon

'for a monkey' is the definition.
(baboon is a kind of monkey)

'source of bananas a blessing' is the wordplay.
'source of' suggests taking the first letters.
'blessing' becomes 'boon' (synonyms).
The initial letter of 'bananas' is 'b'.
'b'+'a'+'boon'='BABOON'

(Other definitions for baboon that I've seen before include "Large long-nosed African or Asian monkey" , "clumsy uncouth person" , "Ground-living primate" , "Uncouth type" , "wild swinger?" .)

I've seen this clue in The Times.
