|discussion=<p><i>Echinochloa walteri</i> grows in wet places, often in shallow water and brackish marshes. It is a native species that extends through Mexico to Guatamala. It is found in both disturbed and undisturbed sites although not in rice fields. Occasional specimens of <i>E. walteri</i> with glabrous lower sheaths and short awns can be distinguished from <i>E. crus-pavonis</i> by their less dense panicles.</p>
