A primitive form of venus fly-trap, the flora of the underground world was almost entirely flesh eaters. The carnivorous plants are the tertiary antagonists of Journey to the Center of the Earth.

Role in Journey to the Center of the Earth
Hannah was menaced by these "florauna in the green canyon". One extented it's mouthparts toward her, before being cut down by Trevor. She was entwined in another one's roots, and it began to sqeeze her. Trevor was attacked by an entire horde of them, but knocked them all senseless. He then uprooted the one that had snared Hannah, killing it and saving her.
