Scientific Name | Strumaria luteoloba Snijman |
Higher Classification | Monocotyledons |

National Status |
Status and Criteria | Vulnerable D2 |
Assessment Date | 2015/05/08 |
Assessor(s) | D. Raimondo & D.A. Snijman |
Justification | Known from only one location in South Africa where it is potentially threatened by livestock overgrazing and trampling. |
Distribution |
Endemism | Not endemic to South Africa |
Provincial distribution | Northern Cape |
Range | Southern Namibia to Eksteenfontein in the Richtersveld, South Africa. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Kahams Mountain Desert |
Description | Rocky slopes in dolomite or granite. |
Threats |
| The most severe threats to plant species in the Richtersveld is severe overgrazing, which has led to a loss of shrub cover, species diversity and erosion due to trampling of exposed soil in many places. This species is not likely to be grazed, but is potentially vulnerable to trampling. |
Population |
This species is known from two isolated subpopulations, one in southern Namibia, the other near Eksteenfontein in the Richtersveld. Strumaria species have extremely limited dispersal abilities (D. Snijman pers. comm. 2015), and dispersal between these two subpopulations is therefore unlikely. It is however possible that other, overlooked subpopulations exist elsewhere in the northern Richtersveld and southern Namibia.
