Xanthoxalis valdiviensis (Barnéoud) Holub
Oxalis valdiviensis is a herbaceous perennial plant producing dense clusters of leaves atop a slowly spreading rhizomatous rootstock; it can grow around 30cm tall[
The plant is harvested from the wild for local use as a food. It is sometimes grown as an ornamental[
The leaves contain oxalic acid, which gives them their sharp flavour. Perfectly all right in small quantities, the leaves should not be eaten in large amounts since oxalic acid can bind up the body's supply of calcium leading to nutritional deficiency. The quantity of oxalic acid will be reduced if the leaves are 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[
