Scientific Name | Pelargonium flavidum E.M.Marais |
Higher Classification | Dicotyledons |
Family | GERANIACEAE |
Synonyms | Pelargonium sulphureum R.Knuth (later homonym), not of (Sweet) Steudel. (1841) |
National Status |
Status and Criteria | Data Deficient - Insufficient Information |
Assessment Date | 2015/04/13 |
Assessor(s) | L. von Staden |
Justification | A rare and poorly known species that is quite likely threatened, but may also be overlooked and possibly more widespread and common. Its risk of extinction cannot be determined based on currently available data. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | De Doorns to Ladismith. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Western Little Karoo, Robertson Karoo, Breede Alluvium Fynbos |
Description | Unknown, probably alluvium fynbos. |
Threats |
| This species is threatened by habitat loss to urban expansion around Worcester, and is possibly already locally extinct in the Hex River Valley around De Doorns. This species' records from the Ladismith area are too imprecise to determine threats, but it is likely to be affected by habitat loss to agriculture if it occurs in similar habitat as around Worcester. |
Population |
A rare and very poorly known species, collected only four times, the most recent record dating from 1980. Three records are from Breede Alluvial Fynbos around Worcester, an extensively modified habitat, with only small fragments remaining. It is possibly already locally extinct within the Hex River Valley, but surveys of remaining fragments around Worcester are urgently needed, to determine if any individuals survive in this area. The fourth record is a disjunction of about 150 km to Ladismith, a much drier area in the Little Karoo. It is not known in what type of habitat the species was recorded, and locality information is very imprecise. It is difficult to estimate how common this species is likely to be in the intervening areas, and an estimate of the number of subpopulations is not possible based on current data.
