National emblem in the list reviewed (7)
I believe the answer is:
thistle
'national emblem' is the definition.
(emblem of Scotland)
'in the list reviewed' is the wordplay.
'in' indicates putting letters inside.
'reviewed' is an anagram indicator (letters reviewed or revised).
'list' anagrammed gives 'istl'.
'the' going around 'istl' is 'THISTLE'.
(Other definitions for thistle that I've seen before include "Scotland's emblem" , "Scots plant emblem" , "Scottish flower" , "Scottish national emblem" , "Scottish plant emblem" .)
