| Scientific Name | Hypoxis hemerocallidea Fisch., C.A.Mey. & Avé-Lall. | Higher Classification | Monocotyledons | Family | HYPOXIDACEAE | Synonyms | Hypoxis obconica Nel, Hypoxis patula Nel, Hypoxis rooperii T.Moore | Common Names | Gifbol (a), Inkomfe (z), Kaffertulp (a), Lotsane (ss), Moli Kharatsa (ss), Star-flower (e), Sterblom (a), Yellow Star (e) |
National Status | Status and Criteria | Least Concern | Assessment Date | 2019/02/25 | Assessor(s) | V.L. Williams, D. Raimondo, N.R. Crouch, J.E. Victor, A.B. Cunningham, C.R. Scott-Shaw, M. Lötter, A.M. Ngwenya & Y. Singh | Justification | Extensive commercial exploitation since 1997 has caused declines in some subpopulations, especially in Gauteng, South Africa, where it is additionally threatened by habitat loss and degradation. This species is however naturally abundant and widespread and therefore not considered in danger of extinction. |
Distribution | Endemism | Not endemic to South Africa | Provincial distribution | Eastern Cape, Free State, Gauteng, KwaZulu-Natal, Limpopo, Mpumalanga, North West | Range | This species is widespread across northern and eastern South Africa, extending to Botswana, eSwatini (Swaziland) and Mozambique. |
Habitat and Ecology | Major system | Terrestrial | Major habitats | Albany Thicket, Grassland, Indian Ocean Coastal Belt, Savanna | Description | It occurs in a wide range of habitats, including sandy hills on the margins of dune forests, open, rocky grassland, dry, stony, grassy slopes, mountain slopes and plateaus. It appears to be drought and fire tolerant. |
Threats | | The corm is consistently heavily harvested for the medicinal plant trade throughout South Africa. The species became especially popular from 1997 following an article in DRUM magazine claiming that it was South Africa's "miracle muthi" and effective in treating the immune system of HIV sufferers (Hawker et al. 1999). The species is often used interchangeably with H. colchicifolia, and in 1994 66% of the muthi shops sold Hypoxis sp. (Williams 2007). In 2001, 40% of traders in the Faraday market sold it and had the equivalent of 18 bags (50kg-size) during the survey (Williams 2007). Williams et al. (2007) estimated that at least 62 000 to 170 000 individual bulbs are sold annually in the Witwatersrand markets. Similarly large quantities are traded in the KwaZulu-Natal markets (Cunningham 1988). In the Eastern Cape, it is heavily traded, unsustainably harvested and sold at high prices (Dold and Cocks 2002). In 1998 M. Pfab (pers. comm.) reported that people with a commercial interest in the species were prepared to pay R1000 for a bakkie load of corms. Land transformation and habitat loss in Gauteng is also a threat to the species. |
Population | This species is naturally widespread and abundant, and in spite of extensive volumes of wild harvesting, is still considered common across most of its range. Monitoring is however needed to gain a better understanding of the impact of harvesting on the risk of extinction of this species.
