Mamyalynne and JRB
Many thanks to both of you. That puts it to bed for me.
I find this crossword very entertaining and so different from the cryptic crosswords to which I am in danger of becoming addicted (thanks to Lie-in King and others whose explanations to others' many queries helped me to understand how they work). This one sends me off looking up places, flowers, birds, insects and so on and so on. I find them a fascinating way to while away an hour or two.
