Scientific Name | Psammotropha marginata (Thunb.) Druce |
Higher Classification | Dicotyledons |
Family | MOLLUGINACEAE |
National Status |
Status and Criteria | Data Deficient - Insufficient Information |
Assessment Date | 2016/10/03 |
Assessor(s) | L. von Staden |
Justification | A very poorly known species, last collected before 1959. It is known from two highly disjunct localities, and may be overlooked in the areas in between, as it is a highly cryptic plant. Based on currently available data, its risk of extinction cannot be assessed. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Eastern Cape |
Range | Somerset East to Port Elizabeth. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Albany Thicket |
Description | Sandy places at low altitude. |
Threats |
The threats to this species are uncertain. It has possibly declined in the Swartkops River Valley, but threats elsewhere in its range are not known. |
Population |
Psammotropha marginata is a small, cryptic herb, and easily overlooked. It is known from only two collections, one from the Swartkops River Valley near Uitenhage (dating from 1830), and one from Botha's Hill south of Somerset East, about 100 km to the north (cited in Adamson 1959).
