Justification | A rare, range-restricted habitat specialist, known from five locations and potentially threatened by competition from alien invasive plants. |

Endemism | South African endemic |
Provincial distribution | Mpumalanga |
Range | Pilgrim's Rest to the Blyde River Canyon. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Scarp Forest, Northern Mistbelt Forest |
Description | Riverine forest, scarp forest or grassy slopes near forest margins. |
Threats |
| This species may have lost some habitat to timber plantations in the past. Plantations are however no longer expanding, and most of its remaining habitat is not protected. It however remains vulnerable to competition from spreading, unmanaged alien invasive plants. |
Population |
An extremely rare species, but possibly overlooked. The genus Scabiosa is taxonomically problematic and collections are difficult to match to described species. S. transvaalensis is however highly distinct and unlikely to be confused with any other taxa. More field surveys are needed to determine the size and extent of the population. The three most recent records are all from the Blyde River Canyon Nature Reserve, but older records with imprecise locality descriptions indicate that it possibly occurs as far as Pilgrim's Rest and Sabie.
