Salvinia Molesta

Description

Salvinia Molesta, commonly known as giant salvinia, is an aquatic fern native to South America. It is an invasive species that has spread rapidly across the world, particularly in warm climates. The plant has small, oval-shaped leaves that are buoyant and form dense mats on the surface of still or slow-moving water bodies. These mats can reach up to 60 cm in height and prevent sunlight and oxygen from reaching the water below, leading to the death of aquatic life.

Taxonomic Information

Appearance

Salvinia Molesta has small, oval-shaped leaves that grow in pairs along a central stem. The leaves are green and have a waxy surface that repels water. This allows them to float on the surface of the water and form dense mats that cover large areas. The plant can grow up to 60 cm in height, with the leaves ranging from 0.5 to 4 cm in length. The roots of the plant are small and feathery, and they do not anchor the plant to the bottom of the water body.
