EOO 11 650 km², this subspecies was once a common lowland endemic, but crop cultivation and urban expansion have reduced its range. Over 80% of its habitat has been lost. It is probably extant at 16 of the 62 historical locations. Large colonies still exist below Gydo Pass and on the Piketberg where hundreds of thousands of plants occur. All other extant subpopulations are severely fragmented, occurring between wheat fields that are seldom burnt, are small (typically fewer than 20 plants) and declining due to habitat degradation as a result of eutrophication and alien plant invasion.
