Justification | Watsonia versfeldii is a range-restricted species, with an extent of occurrence (EOO) of 716 km². It is known from only a few, scattered subpopulations, but it has no severe threats and is not suspected to be in danger of extinction. It is therefore listed as Least Concern. |
Distribution |
Endemism | South African endemic |
