By Mindy Weisberger, CNN(CNN) — Sticky “hairs” on two plant species in the Saxifraga genus led famed British naturalist Charles Darwin to wonder: Could some plants in this genus be carnivorous? However, to be carnivorous, a plant must lure, trap and consume insects, and Darwin’s experiments with Saxifraga plants couldn’t conclusively demonstrate that the plants fit the bill. Genetic analysis then clarified S. candelabrum’s relationship to other sticky carnivorous plants, revealing shared genes linked to traits such as prey attraction, digestion and nutrient absorption. “Carnivory is likely far more widely distributed among angiosperms” — or flowering plants — “than previously believed, and new carnivorous plant lineages may be discovered in the future.” The plant’s alpine habitat is a first for carnivorous plants, Soltis added.
