International group cut down strangely typical trees (9)
I believe the answer is:
eucalypti
'trees' is the definition.
(eucalyptus is a kind of tree)
'international group cut down strangely typical' is the wordplay.
'international group cut down' becomes 'eu' (I can't explain this - if you can you should believe this answer much more).
'strangely' indicates an anagram.
'typical' anagrammed gives 'calypti'.
'eu'+'calypti'='EUCALYPTI'
Can you help me to learn more?
(Other definitions for eucalypti that I've seen before include "Gums" , "Oil producers" , "shrubs" , "Australian trees" , "Oil sources" .)
