Gee thanks Dave, but not at all sure of the wordplay..I can't see an anagram indicator for a start.
Bo is a tree, but no word for View which can have an X or Y removed which can be put "over" comes to mind.
I went for Etna as in my previous post as Xante is a liqueur made from a pear tree, then used the reversal and removed 'X'. Perhaps dave1948 could let us know whenever the answer is published.
For Penelope 2 and all others who contributed to the discussion the answer to 16d is given as Nebo (which was the finally verdict of Answerbank contributors) Well done !!
