Justification
Hereroa willowmorensis is a poorly known species, last recorded in 1950. It is possibly insufficiently distinct from other Hereroa species, as the genus is taxonomically problematic, making it difficult to identify specimens with certainty. Further taxonomic study is urgently needed, and until resolved, this species' risk of extinction cannot be assessed.
Distribution
Endemism
South African endemic
Provincial distribution
Eastern Cape
Range
This species' distribution is uncertain. It is possibly endemic to the Willowmore district in the Eastern Cape.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Succulent Karoo
Description
It occurs in shaly or gravelly soils in arid shrubland.
Population

This is a very poorly known species, and was last recorded in 1950. It may be overlooked, but it is also likely that it is difficult to distinguish from other species in the genus, as Hereroa is in need of taxonomic revision. The population size and trend is not known.
