after doing much reading on the aquatic fauna found around the Petén basins, I learned that both Elodea sp. and Ceratophyllum sp. are found extensively around some parts of Lake Petén banks and shorelines. This inspired me to represent a shallow river bank area with Hornwort growing and left to trail along the surface to create a shady area.
