Scientific Name | Sparaxis caryophyllacea Goldblatt |
Higher Classification | Monocotyledons |
Family | IRIDACEAE |
Common Names | Speckle Satinflower (e) |
National Status |
Status and Criteria | Vulnerable D2 |
Assessment Date | 2014/09/29 |
Assessor(s) | P. Goldblatt, D. Raimondo & L. von Staden |
Justification | A rare, localized species, known from one location and potentially threatened by habitat loss and degradation due to road maintenance and overgrazing. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Nardous Mountain. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Doringrivier Quartzite Karoo, Bokkeveld Sandstone Fynbos |
Description | Rocky, transitional sandstone-clay slopes, western aspect. |
Threats |
Fynbos on the summit of the Nardous Mountain above the population continues to be lost to crop cultivation, however, this species' rocky habitat is unlikely to be ploughed. It may be impacted by road construction and clearing of road verges (Goldblatt and Manning 2013). The area was noted to be subjected to grazing in the past, but it does not appear to have negatively impacted the population. Habitat degradation and loss to erosion remains a potential threat. |
Population |
A rare, localized species known from only one subpopulation of fewer than 200 mature idividuals. It is however quite likely overlooked and more widespread as its habitat remains poorly explored (Goldblatt and Manning 2013). The population is currently stable and under no immediate threat (Goldblatt and Manning 2013).
