Rewriting this with new info..
Peace Lily
Here's a blurb about its affect on cats, which may not be the same inrabbits. However, being such a common houseplant, and there'sno hugely dire warnings out there, I don't think eating just the tipwill do much damage. If its the same as a cat, then itprobably tasted pretty awful.
I'll keep looking for info, but watch carefully for signs ofgastronomical upsets-- ie: if the bunny stops eating orappears to be having gas pains, etc.
