Lenzia is a monotypic genus of flowering plants belonging to the family Montiaceae.

[2] Its native range is southern South America and it is found in Argentina and Chile.

[2] The genus name of Lenzia is in honour of Harald Othmar Lenz (1798–1870), a German teacher and naturalist in Thuringia and also historian of science, as well as a specialist in fungi and sponges.

[3] The Latin specific epithet of chamaepitys refers the Ancient Greek words χαμαί khamaí latinized into chamae meaning "on the ground, to the ground/earth", and also πιτυς pitys meaning "pine", from resemblance of the foliage to that of pine trees.

[4] Both genus and species were first described and published in Linnaea Vol.33 on page 222 in 1864.
