Scientific Name | Osteospermum spathulatum (DC.) Norl. |
Higher Classification | Dicotyledons |
Family | ASTERACEAE |
Synonyms | Tripteris spathulata DC. |
National Status |
Status and Criteria | Data Deficient - Insufficient Information |
Assessment Date | 2016/01/26 |
Assessor(s) | L. von Staden |
Justification | A poorly known species last collected in 1914. It is possibly threatened, but based on available information, its risk of extinction cannot be assessed. Field surveys and taxonomic studies are urgently needed. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Eastern Cape |
Range | Uitenhage to Grahamstown. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Albany Thicket |
Description | Dry karroid slopes. |
Threats |
| Threatened by ongoing habitat loss to urban and industrial expansion around Uitenhage, Redhouse and Coega. |
Population |
A very poorly known taxon, last recorded in 1914. It is known from a few records between Uitenhage and Coega, where it is possibly now locally extinct due to extensive habitat loss and degradation, but may also be overlooked. Then it is known from a single, highly disjunct record from hills north-west of Grahamstown. It is not known whether this is an aberrant record, or whether the population is continuous between Uitenhage and Grahamstown. It may be overlooked, as this area is botanically relatively poorly sampled.
