Venda cycad, Venda-broodboom
Taxonomy & Nomenclature
Conservation Status
Possibly Extinct in the Wild (Donaldson, 2010; Bösenberg, 2022) or Rediscovered in the wild (if viable) (cf. Bösenberg et al., 2020)
Last record: 2004 (Donaldson, 2010; Bösenberg, 2022); 2021 (Bösenberg et al., 2020)
IUCN RedList status: Critically Endangered (Possibly Extinct in the Wild)
3 individuals were reported in 2021 (Bösenberg et al., 2020), but it is not known if they persist, and as the species is dioecious it would need to contain both a male and female for the population to be viable.
