The name of this taxon is spelled wrongly as Rumex chrysocarpus in the Flora of N. America[].

Common Name: Amamastla dock

General Information

Rumex chrysocarpos is a herbaceous perennial plant growing from a vertical rootstock; the stems can be ascending or erect, usually growing around 40 - 60cm tall, occasionally to 80cm[].
The plant is harvested from the wild for local use as a food.

Known Hazards

Plants can contain quite high levels of oxalic acid, which is what gives the leaves of many members of this genus an acid-lemon flavour. Perfectly alright in small quantities, the leaves should not be eaten in large amounts since the oxalic acid can lock-up other nutrients in the food, especially calcium, thus causing mineral deficiencies. The oxalic acid content will be reduced if the plant is cooked. People with a tendency to rheumatism, arthritis, gout, kidney stones or hyperacidity should take especial caution if including this plant in their diet since it can aggravate their condition[].
