Aristida adscensionis is a species of grass known by the common name sixweeks threeawn.[2] It is native to the Americas but it is distributed nearly worldwide. It grows easily in disturbed and waste areas and has potential to become a weed.[3]

Description

[edit]

This annual bunchgrass is quite variable in appearance, its size and shape determined largely by environmental conditions. It grows in a tuft to heights between 5 and 80 centimeters. It forms a narrow inflorescence of spikelets, each fruit with three awns.
