Are there any biennial carnivorous plants?

[v074]

Are there any biennial carnivorous plants?.It seems like a peculiar question to ask, but I am just curious. For example, I have heard of annual carnivorous plants(like Utricularia Multifida[Polypompholyx])and perrenial ones(like Dionnae Muscipula), but are there any biennial carnivorous plants?

Drosera brevifolia is often referred to as biennial, but in my experience it is perennial.
