Justification
A population reduction of at least 50% is estimated based on a >60% habitat loss to wheat cultivation and vineyards over the past 100 years (generation length 50 years). EOO 205 km², AOO <205 km², habitat quality at three known remaining locations continue to decline due to alien plant invasion.
Distribution

Major habitats
Swartland Shale Renosterveld, Breede Shale Renosterveld, Swartland Granite Renosterveld, Swartland Silcrete Renosterveld, Swartland Alluvium Fynbos, Breede Alluvium Fynbos
Description
Damp clay flats.
Threats
More than 60% of this species' habitat has been lost to wheat and vineyard cultivation within the past 100 years, and although only small fragments of natural vegetation remains, loss and degradation is ongoing, particularly due to invasion by alien invasive plants.
