Scientific Name | Wahlenbergia costata A.DC. |
Higher Classification | Dicotyledons |
Family | CAMPANULACEAE |
National Status |
Status and Criteria | Data Deficient - Taxonomically Problematic |
Assessment Date | 2018/05/31 |
Assessor(s) | L. von Staden |
Justification | The genus Wahlenbergia is poorly understood and in need of taxonomic revision. Manning and Goldblatt (2012) indicate that Wahlenbergia costata possibly does not warrant recognition as a separate taxon. Until taxonomically resolved, this species' risk of extinction cannot be assessed. It is listed as Data Deficient - Taxonomically Problematic (DDT). |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | This species is endemic to South Africa, however, its distribution is uncertain. According to Sonder (1894), the type collection is from the eastern Sandveld near Paleisheuwel. Snijman (2013) indicates that it occurs in southern Namaqualand north of Nuwerus. Collections in the National Herbarium (PRE) suggests that it is widespread across Namaqualand, possibly extending as far south as the Koue Bokkeveld. |
