A plant from the list (7)
I believe the answer is:
thistle
'a plant' is the definition.
(I know that thistle is a type of weed)
'from the list' is the wordplay.
'from' indicates anagramming the letters (the anagram comes from the same letters).
'the'+'list'='thelist'
'thelist' is an anagram of 'THISTLE'.
(Other definitions for thistle that I've seen before include "The list includes Scottish emblem" , "Prickly plant, emblem of Scotland" , "Prickly weed" , "Flower of Scotland" , "Scots plant emblem" .)
