Higher Classification | Monocotyledons |
Family | IRIDACEAE |
National Status |
Status and Criteria | Rare |
Assessment Date | 2021/08/11 |
Assessor(s) | L. von Staden & T. Patel |
Justification | This subspecies has a highly restricted range, with an extent of occurrence (EOO) of 41 km², and an area of occupancy (AOO) of 36 km². It is locally common and not threatened. It is therefore listed as Least Concern under the IUCN criteria, and nationally as Rare. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | This taxon is restricted to the extreme southern Cape Peninsula in South Africa, between Smitswinkel and Olifantsbosch. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Peninsula Sandstone Fynbos |
Description | It occurs in seasonally marshy flats and sandy plateaus in sandstone fynbos. |
Threats |
| This subspecies occurs within a protected area where there are no threats to the population. |
Population |
It is locally abundant in suitable habitat on the southern Cape Peninsula. iNaturalist observations between 2019 and 2021 indicated that there were two subpopulations of two hectares with about 30 plants each, while a third subpopulation had 200 plants in five hectares. There is however still a need to do a thorough survey of the entire population to accurately estimate the overall number of mature individuals. As there are no threats, the population is suspected to be stable.
