Scientific Name | Lachenalia adamii G.D.Duncan |
Higher Classification | Monocotyledons |
Family | HYACINTHACEAE |
National Status |
Status and Criteria | Vulnerable D2 |
Assessment Date | 2022/08/23 |
Assessor(s) | G.D. Duncan & H. Mtshali |
Justification | This Northern Cape endemic is very localised, with an extent of occurrence (EOO) and area of occupancy (AOO) of 4 km². It is known from one location that is potentially vulnerable to future habitat degradation as a result of alien invasive plant spread. The population is not suspected to be declining, and it is therefore listed as Vulnerable under criterion D2. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Northern Cape |
Range | This species has a restricted distribution in the Northern Cape Province, South Africa, where it occurs on the Bokkeveld Escarpment. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Vanrhynsdorp Shale Renosterveld |
Description | Plants are found in shale scree on steep, southwest-facing river banks at 600 m.a.s.l. |
Threats |
| The only known site where this species occurs is formally protected; however, alien invasive plants (Acacia saligna and Eucalyptus camaldulensis) have been observed in low densities. If these are not controlled, they are likely to increase in density and eventually result in habitat alteration that will cause the population to decline. |
Population |
This species is only known from the type collection. Plants occur in scattered, small groups of up to 15 plants. The population is not suspected to be declining.

Population trend | Unknown |
