  "definition": "West Indian marsh grass (Hymenachne amplexicaulis), also known as trompetilla, is a perennial grass adapted to wetland habitats. It is the only species in the genus Hymenachne that is present in Florida. The stem, in grasses called a culm, is glabrous (hairless), erect, up to six feet tall and filled with a white pith or aerenchyma. In aquatic plants, aerenchyma allows the easy movement of oxygen from the leaves to the roots. Stems that are submerged quickly produce roots from nodes and anchor to the wetland floor. The panicles are narrow, spike-like, cylindrical, 4-15 inches long and 0.4 inches wide. Leaf blades are 4-16 in. long, and up to 1½ inches wide, mostly hairless, heart-shaped at the base with earlike appendages and clasp around the stem.",
