Article about list circulating in plant (7)
I believe the answer is:
thistle
'plant' is the definition.
(type of plant)
'article about list circulating' is the wordplay.
'article' becomes 'the' (the definite article in English).
'about' means one lot of letters goes inside another.
'circulating' is an anagram indicator.
'list' with letters rearranged gives 'istl'.
'the' enclosing 'istl' is 'THISTLE'.
'in' is the link.
(Other definitions for thistle that I've seen before include "Prickly plant, emblem of Scotland" , "The Scottish weed?" , "Flower of Scotland" , "that blows down when it's windy" , "Scottish national emblem" .)
