Ruizia parviflora is a very rare shrub from the family Malvaceae.

[1] Ruizia parviflora is a much-branched low shrub which can reach a height up to four metres.

The upperside of the leaf is obtused and scabrous, the underside is thinly scurfy.

After botanist Philip Burnard Ayres collected the last known specimens in 1863 it was long regarded as lost until 76 individuals were rediscovered in April 2001 by the Mauritian botanists Vincent Florens and Jean-Claude Sevathian, from the Mauritius Herbarium, on a rocky slope of the Corps de Garde six kilometres apart from the type locality.

It was assumed that this species has reduced its original range due to competition with invasive alien plants and seed predation by invasive monkeys and rats.
