Distribution

 
Habitat

With only a single population known, this must be one of the most endangered hoareas as most of the adjacent possibly suitable locations have been converted into vineyards. It is found on cobbled flats of the Breede River in alluvial fynbos, seasonally wet or marshy. It flowers in December to January when the leaves are still present and the soil begins to dry up.
