Justification:
Rhoicissus napaeus is an evergreen tendril climber, found only within Eswatini.  It is however quite widespread within the country, with an estimated extent of occurrence of 3915.684 km2. It appears to be tolerant of habitat degradation, and is therefore not considered to be threatened.  Based on this, it has been assessed as Least Concern.
