Notes: FNA5: "Rumex triangulivalvis is the most common and widespread species of the R. salicifolius group. It often occurs in ruderal habitats and may be expected outside its present range.

The names Rumex salicifolius and R. mexicanus (in the broad sense) were commonly applied to this species by many North American and European authors."
