Thank you dr b,
I was just looking at that and trying to decide if it was the right fit / solution as you sent it across. I couldn't find it in a list of shrubs but if you have thanks. I think it must be the solution.
I'm just learning this suff and this crossword is pretty tough I'm just struggling with the last corner now . do you have any ideas on 20d) Green alga doesn't live with fine oxygen absorbed (7), --O---- ?
