Higher Classification | Monocotyledons |
Family | IRIDACEAE |
Synonyms | Synnotia parviflora G.J.Lewis |
Common Names | Tiny Satinflower (e) |
National Status |
Status and Criteria | Vulnerable B1ab(i,ii,iii,iv,v)+2ab(i,ii,iii,iv,v) |
Assessment Date | 2014/09/25 |
Assessor(s) | N.A. Helme, D. Raimondo, P. Goldblatt, J.C. Manning & L. von Staden |
Justification | A range-restricted (EOO 997 km²) habitat specialist, that remains only at between eight and 10 locations after extensive habitat loss, predominantly to crop cultivation. It continues to decline due to ongoing habitat loss, fragmentation and degradation, as well as competition from alien invasive plants. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Saldanha to Darling. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Saldanha Granite Strandveld, Swartland Granite Renosterveld, Hopefield Sand Fynbos |
Description | Coarse, granite derived soils, often in granite outcrops. |
Threats |
| Around Langebaan, Sparaxis parviflora is known from a few granite outcrops where it is threatened by ongoing habitat loss to urban expansion. Around Darling, four known subpopulations survive on isolated fragments after extensive habitat loss to crop cultivation. These small, isolated subpopulations are threatened mainly by ongoing habitat degradation and competition from alien invasive plants. Around Hopefield, this species is also threatened by competition from dense, unmanaged invasive wattles (N.A. Helme pers. obs.). |
