Derris spp have rotenone in their roots, which are crushed and used to
stun fish. Derris is a woody vine native to SE Asia, but I think there
is another rotenone-containing plant (cube'?) which is South American
and is used for the same purpose.
Rotenone is often used as a "safer" botanical insecticide these days,
but it's just as toxic to fish and amphibians as ever.
