I believe the answer is:
wilts
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">withers</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for wilts that I've seen before include "Southern county" , "Flags" , "part of the kingdom" , "(Of plant) becomes limp" , "Droops; county (abbr.)" .)
