Threats
Eucomis comosa has only recently been recorded in the Durban traditional medicine markets (e.g. von Ahlefeldt et al. 2003) and it may occur sporadically in the Johannesburg markets (it hasn't been positively identified there yet). It is, however, commonly traded in the Eastern Cape and not much of it can be found in the wild (A.P. Dold pers. comm., 2008). Dold and Cocks (2002) list it as the 58th most common species in the Eastern Cape markets, but it is sold in small quantities. Some decline has probably occurred, but the extent and time frames aren't clear. It is likely that var. striata, which has a limited distribution within KwaZulu-Natal and an EOO of ± 14 1000 km², is more vulnerable than var. comosa is due to harvesting for the medicinal plant trade. While this assessment has not considered the individual varieties, it may be of value to separate the assessments in future.
