European university with typical wild trees (9)
I believe the answer is:
eucalypti
'trees' is the definition.
(eucalyptus is a kind of tree)
'european university with typical wild' is the wordplay.
'european' becomes 'e' (abbreviation e.g. EU).
'university' becomes 'U' (abbreviation for university).
'with' means one lot of letters go next to another.
'wild' indicates anagramming the letters.
'typical' is an anagram of 'calypti'.
'e'+'u'+'calypti'='EUCALYPTI'
(Other definitions for eucalypti that I've seen before include "Gums" , "Gum trees" , "Oil sources" , "Australian trees" , "Oil producers" .)
