OxalisMyrtillus

Oxalis myrtillus is a species of flowering plant in the family Oxalidaceae, commonly known as myrtle wood sorrel. It is native to the Mediterranean region, with its range extending across southern Europe, North Africa, and parts of the Middle East. This perennial herb typically grows in woodland clearings, scrubland, and rocky areas, often found in association with oak and pine forests.

The plant is characterized by its trifoliate leaves, similar to other species of Oxalis, which are heart-shaped and possess a sour taste due to the presence of oxalic acid. The flowers are usually small and white or pale pink, blooming from spring to early summer. Oxalis myrtillus has a rhizomatous root system, allowing it to spread and form colonies.

Historically, plants in the Oxalis genus have been used in traditional medicine for various ailments, though scientific evidence supporting these uses is often limited. Due to its oxalic acid content, consumption in large quantities can be harmful. The specific ecological role and economic importance of Oxalis myrtillus are not widely documented. It is generally considered a wild plant with no significant agricultural or horticultural applications, though its aesthetic appeal may lead to its occasional use in naturalistic gardens.
