In 1999 I conducted experiments to look for enzymatic activity on the glandular leaves of Ibicella lutea (Pedaliaceae), also known as the devil's claw or unicorn plant. I saw no evidence for enzymes, inferred the plants were not carnivorous, and wrote that 'These are interesting plants, but I have no room for them in my carnivorous garden. The seeds I will send to the ICPS seed bank will be my last'. Furthermore, on my web site I wrote that '… on the whole, I have lost interest in this non-carnivore' (Rice 2004). Ah, how presumptuous I was.
