Justification
EOO 3 km², AOO <0.7 km², an extremely localized species. The population has been reduced and fragmented by habitat loss to agriculture and infrastructure development, and currently three small subpopulations remain, spread across four small fragments, where they are threatened by ongoing habitat loss and degradation as a result of industrial development and overgrazing. The population size is estimated to be no more than 600 mature individuals.

Description
White sandy flats.
Threats
Past habitat loss to crop cultivation has severely reduced the habitat of the extremely limited distribution range of this species, and plants remain on a few fragments of only a few hectares each. Remaining subpopulations are threatened by ongoing habitat loss to urban and industrial expansion of Vredenburg and Saldanha as well as overgrazing due to overstocking of small fragments.
Population

Romulea elliptica is currently known from only three subpopulations, confined to a very limited area between Vredenburg and Saldanha. Two subpopulations are spread over a cluster of three small fragments dissected by roads and other infrastructure, while a third subpopulation is located on an isolated fragment about 2.3 km to the south-east. The largest subpopulation consists of between 200 and 400 mature individuals, and the total population size is estimated as no more than 600 mature individuals.
