L. von Staden
A widespread (EOO 10 290 km²) and still fairly common taxon, in spite of extensive habitat loss and degradation. It is declining in the southern part of its range, but is not yet in danger of extinction.
South African endemic
Provincial distribution
Western Cape
Olifants River Valley and Sandveld to the Cape Peninsula.
Habitat and Ecology
Major system
Major habitats
Deep sandy soils.
This taxon has declined on the Cape Peninsula and Cape Flats due to habitat loss to urban expansion, but recent records indicate that it still occurs around Milnerton and Bloubergstrand. Around Malmesbury and Darling it is threatened by dense infestations of alien invasive plants. Deep sandy soils in the Sandveld are being rapidly ploughed up for the cultivation of potatoes and rooibos tea. This taxon is an annual, and is suspected to be resilient to disturbance, and likely to be able to recolonise previously disturbed habitats. Therefore only complete habitat loss to urban expansion is likely to cause ongoing population decline.

This taxon is locally common in sandy soils, particularly in the Sandveld. The population is declining in the southern parts of its range due to ongoing habitat loss to urban expansion, but this affects only a small proportion of the population.
