Justification | Romulea albiflora is known from three collections from one continuous subpopulation. Part of the subpopulation was lost to cereal cultivation and the rest occurs on the edge of a ploughed field. There are fewer than 250 mature individuals extant, decline due to crop cultivation is continuing. It has an extent of occurrence (EOO) and area of occupancy (AOO) of less than 1 km², and is therefore listed as Critically Endangered under the criteria B1ab(ii,iii,iv,v)+2ab(ii,iii,iv,v); C2a(ii). |
