Justification
This species has an extent of occurrence (EOO) of 2318 km²and is naturally rare and known from fewer than 10 locations. Collecting for the traditional medicine trade has led to declines in at least three of the seven known locations (representing 43% of the total population). The tubers are not easily distinguishable from those of Alepidea amatymbica, a species which is also heavily harvested and in high demand. It is therefore listed as Vulnerable under criteria A and B.

Habitat and Ecology
Major system
Terrestrial
Major habitats
Amathole Montane Grassland
Description
It is found in grassland on mountain slopes, growing at an altitude of 1000-1770m.
Threats
This species is used for traditional medicine and is traded in the Eastern Cape traditional medicine markets (A.P. Dold, pers. comm., 2008). The species is very similar to A. amatymbica and would not be differentiated by collectors/traders since the tubers are near-impossible to tell apart (A.P. Dold, pers. comm., 2008). Alepidea amatymbica/macowanii is very commonly sold in the Eastern Cape markets and was ranked nineteenth in the region (Dold and Cocks 2002). Alepidea macowanii is collected wherever and whenever the opportunity arises by medicinal plant collectors (A.P. Dold, pers. comm., 2008). The species is also naturally rare (P.J.D. Winter, pers. comm., 2008) and only known from a few locations. Given that there has been at least a 30% decline in the A. amatymbica population in the last 60 years (three generations), it is very likely that there has been a similar decline in the A. macowanii population due to its popularity as a traditional medicine and the opportunistic harvesting that is likely to have occurred. Furthermore, at least one of the subpopulations/locations (at Katberg) is on communal land and is therefore easily accessible to harvesters.
