Justification
The genus Wahlenbergia is poorly understood and in need of taxonomic revision. Manning and Goldblatt (2012) indicate that this species possibly does not warrant recognition as a separate taxon. Until taxonomically resolved, this species' risk of extinction cannot be assessed.

Endemism
South African endemic
Provincial distribution

Range
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.
