}}Triplasis is a genus of North American plants in the grass family. Sandgrass is a common name for plants in this genus.[2] The genus name Triplasis is Greek, meaning "threefold", referring to the triple nerved lemmas.[3] DescriptionThe plants are slender-tufted perennials or annuals with short, slender leaf blades.
