D. Raimondo, L. von Staden & T. Patel
Justification
This range-restricted habitat specialist (extent of occurrence 717 km²) is known from four locations and it is potentially threatened by habitat degradation due to agricultural and urban expansion and alien plant invasion. It is therefore listed as Vulnerable under criteria D.
Distribution
Endemism
South African endemic
Provincial distribution
KwaZulu-Natal
Range
this species is endemic to South Africa, and is found on the hills between Durban and Pietermaritzburg in KwaZulu-Natal.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Northern Coastal Forest, Scarp Forest
Description
It occurs in scarp forest, hanging from moss cushions or patches of humus on dripping wet sandstone cliffs that are mostly inaccessible.
Threats
This species occurs within a rapidly expanding urban area. Although development is unlikely to directly impact this species' cliff face habitat, fragmentation and degradation of natural ecosystems, as well as changes in water drainage and runoff due to surrounding development is inevitable. Most remaining fragments of natural vegetation in the area are also densely invaded by alien invasive plants, which could potentially outcompete native species such as this one.
Population

This is a localized habitat specialist, known from only four locations. It has a stable population trend.
