Scientific Name | Gethyllis longistyla Bolus |
Higher Classification | Monocotyledons |
Family | AMARYLLIDACEAE |
National Status |
Status and Criteria | Rare |
Assessment Date | 2016/11/01 |
Assessor(s) | D.A. Snijman & D. Raimondo |
Justification | Gethyllis longistyla is a relatively widespread, but rare species, typically occurring in small subpopulations. It is not currently threatened. It is therefore listed under the IUCN 3.1 Criteria, globally, as Least Concern but is nationally categorised as Rare. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Eastern Cape, Western Cape |
Range | This species is endemic to South Africa, and is found in Sneeuberg, Agter-Sneeuberg and Nuweveld Mountains. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Eastern Upper Karoo, Upper Karoo Hardeveld, Eastern Lower Karoo, Besemkaree Koppies Shrubland, Karoo Escarpment Grassland |
Description | It grows on summits of rocky dolerite ridges. |
Threats |
| There are currently no severe threats to this species. However, its distribution range falls within an area earmarked for shale gas extraction. It is not certain what the impact of gas extraction and associated infrastructure development on its habitat is likely to be, but dolerite intrusions tend to have low to no gas deposits, and it could possibly be spared from future habitat loss and degradation. |
Population |
Gethyllis longistyla is known from only a few records, scattered over a wide area. It is rare, and easily overlooked, as it is cryptic when it is not flowering. Flowers, which appear in late summer, last only a few days. Subpopulations are typically small, occurring in subpopulations consisting of 20 or fewer plants.
