Justification
This species has a limited distribution range and has an extent of occurrence (EOO) of 386 km² and an area of occupancy (AOO) of 40 km². It is known from between 6-10 locations. The population is estimated to be less than 2500 plants, consisting of very small subpopulations with typically fewer than 50 mature individuals but with two larger subpopulations of between 100-500 mature individuals. Much of the habitat has been transformed due to forestry plantations and the population is declining due to alien plant invasions and inappropriate fire management. It therefore qualifies for listing as Vulnerable under criterion B and C.

Description
Plants grow on moist, sandy soil along river banks at an altitude between 300-600 m.
Threats
The main threat to this species was afforestation, which has now ceased. Local forestry companies have put effort into removing alien vegetation and pine plantations. However, alien invasive plants and inappropriate fire management continue to result in degradation of this species' habitat. Insect infestation by a gall forming species has also been noted in one of the subpopulations.
Population

The population is estimated to consist of less than 2500 plants found in 10 subpopulations. Most subpopulations are small, having fewer than 50 individuals, and only two big subpopulations occur along the Moffet Dam. These subpopulations have between 100-250 plants and 250-500 plants respectively. This species appears to be scattered throughout the mountain slope and a few more undiscovered subpopulations might exist. Four new records were documented confirming the presence of this species along the Great Winterhoek Mountains, which is an extension of its range.
