Carnivorous plants are among the most evolutionarily fascinating organisms on Earth. They independently evolved carnivory at least twelve separate times across ten plant families, solving the same problem — nitrogen-poor soils — with strikingly different traps: pitfall pitchers, snap traps, sticky mucilage, suction bladders, and lobster-pot chambers. This encyclopedia documents 317 species with detailed cultivation guides, trap biomechanics, habitat ecology, and conservation status.
