Off to a quick start in the NW corner, but found the rest a bit more of a struggle. There was one piece of vocabulary that was unfamiliar to me (13dn), but I was relieved to find the plant quickly, as they are usually a bit more obscure. Easier than recent Friday puzzles - a steady half an hour solve.
