Some of the nastier plants that have mastered organofluorine
chemistry
that are native to South Africa and Australia are not to be trifled
with. See for example:

Well blow me down! I never knew that Oz had any plants like this and
I didn't know that 1080 was a naturally occurring poison - and to be
accurate I still don't as I haven't done a further search to find out
abot the origins of 1080, but to find that it occurs in a plant is
simply amazing.

Anyway, you're right aobut not trifling with it as apparently mammals
are hsitory once they ingest 1080 and although dogs are teh usual
victims, I guess the same would apply to humans.

But my vote is still for Ricinus seeds.

It certainly seems to be the best candidate for mass murder, but
probably 1080 would be more effective if one was planning to murder
one single person :-))
