Oxalis ( /ˈɒksəlɨs/) is by far the largest genus in the wood-sorrel family Oxalidaceae: of the approximately 900 known species in the Oxalidaceae, 800 belong here. The genus occurs throughout most of the world, except for the polar areas; species diversity is particularly rich in tropical Brazil, Mexico and South Africa.

Many of the species are known as wood-sorrels (in American English typically written "woodsorrels" or "wood sorrels") as they have an acidic taste reminiscent of the unrelated sorrel (Rumex acetosa) proper. Some species are called yellow-sorrels or pink-sorrels after the color of their flowers instead. Other species are colloquially known as false shamrocks, and some are rather misleadingly called "sourgrasses". For the genus as a whole, the term oxalises is also used.

These plants are annual or perennial. The leaves are divided into three to ten or more obovate and top notched leaflets, arranged palmately with all the leaflets of roughly equal size. The majority of species have three leaflets; in these species, the leaves are superficially similar to those of some clovers. Some species exhibit rapid changes in leaf angle in response to temporarily high light intensity to decrease photoinhibition.

Violet Jane Wood (née Hodges; 2 September 1899 – 29 February 2012) was a British supercentenarian who was the oldest person in the United Kingdom for almost a year before her death at the age of 112 years, 180 days.

Violet Jane Hodges was born in Faversham, Kent, England. She was married to Harry Wood for 62 years until his death at the age of 92.

She drove a car until she was 80 years old, and worked on a farm all of her life. She credited her longevity to eating toast and pickles.

Her sisters Bertha and Marjorie lived to the ages of 106 and 99 respectively. She has one son named David who is 87 years old.
