Well I'm stuck in the bottom right. 17d, Old socialist, Spooner's Napoleon X. I have T?N? ??N? and can't think of any combinations of Ten and King or Pink that would give me am old socialist. Then 18d, two beats for number one, perhaps. S?A?? ?I?. And 25ac, so-called trees, those found on the coast line, A?A???S. I can make a case for Acacias but get no help from that for the other two. I await enlightenment.
