This thread made me recall that I've often wondered why the small community on the NW edge of London between Enfield and Potters Bar was called Botany Bay as it is well inland and nowhere near a bay, although there are nurseries nearby so the botanical connection is there.

Apparently, checking the Oxford Dictionary of London Place Names, it's not a historic name and I believe first appeared on maps in 1819. The place was named after the Australian settlement as it was considered to be fairly remote and you might as well be going to Botany Bay.

Not relevant to this thread but it reminded me to clear up a nagging question.
