<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">christmas purchase</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 tree that I've seen before include "Maybe plane" , "eg Ash, oak" , "Eg, laburnum" , "Forest plant" , "- Frog; - house" .)
