Plant found in Brazil capturing worms underground

 　　BEIJING Jan. 10 (Xinhuanet) -- Scientists have found a plant in Brazil using leaves to capture the tiny worms in the soil, according to Monday's Proceedings¹ of the National Academy of Sciences in the U.S.

　　The plant, named Philcoxia, was found in the tropical grassland² of Brazil, where the biodiversity is well conserved³.

　　As the scientists searching for the answer of why the plant grows the leaves underground, they found the 1.5 millimeters-wide leaves can trap the worms and produce a digestive enzyme⁴ to help its roots to absorb the nutrition.

　　Although it is not the first meat-eating plant to be discovered, the finding has still "broaden up our perception about plants," according to researcher Rafael Silva Oliveira, a plant ecologist at the State University of Campinas in Brazil.

　　It suggests that carnivorous plants "may have evolved independently more times in plants than previously thought," he added
