The tuber contains a multi-layered tunic. The outer layers are dark brown and spongy while the inner layers are a translucent white colour.

The ellipsoid capsule contains glossy black spherical seeds.

Distribution and habitat
This species is endemic to the Northern Cape and Western Cape of South Africa. It is found on deep sandy flats and stony clay slopes between Namaqualand to Bredasdorp.

Conservation
Lachenalia unifolia is the most common Lachenalia species and is considered to be of least concern by the South African National Biodiversity Institute (SANBI). While it is declining due to a combination of habitat loss and alien vegetation, the rate of decline is not currently considered high enough to put this species at risk of extinction.

Uses
This species is valued as an ornamental plant.
