English university with typical assorted trees (9)
I believe the answer is:
eucalypti
'trees' is the definition.
(eucalyptus is a kind of tree)
'english university with typical assorted' is the wordplay.
'english' becomes 'e' (abbreviation).
'university' becomes 'u' (abbreviation for university).
'with' is a charade indicator (letters next to each other).
'assorted' is an anagram indicator.
'typical' anagrammed gives 'calypti'.
'e'+'u'+'calypti'='EUCALYPTI'
(Other definitions for eucalypti that I've seen before include "Antipodean natives" , "Australian trees" , "Gum trees" , "shrubs" , "Oil producers" .)
