Ampelodesmos is a genus of Mediterranean plants in the grass family, which is known by the common names stramma, Mauritania grass, rope grass, and dis grass. It is classified in its own tribe Ampelodesmeae within the grass subfamily Pooideae. The genus probably originated through ancient hybrid speciation, as a cross between parents from tribes Stipeae and Phaenospermateae. Its nodding flower panicles can be nearly two feet long. In its native area it is used as a fiber for making mats, brooms, and twine. see Cortaderia \n* Ampelodesmos australis - Cortaderia pilosa
