Lötter & A.M. Ngwenya | Justification | Considered to be LC-declining because medium-large volumes of bulbs are evident in the medicinal markets, but the species appears to be widespread in southern Africa. It has experienced some decline in the past, but the extent and time frame are unknown, declines are not suspected to have exceeded 10% of the population. |
