Justification
A poorly known species last collected in 1914. It is possibly threatened, but based on available information, its risk of extinction cannot be assessed. Field surveys and taxonomic studies are urgently needed.

South African endemic
Provincial distribution
Eastern Cape
Range
Uitenhage to Grahamstown.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Albany Thicket
Description
Dry karroid slopes.
Threats
Threatened by ongoing habitat loss to urban and industrial expansion around Uitenhage, Redhouse and Coega.
Population

A very poorly known taxon, last recorded in 1914. It is known from a few records between Uitenhage and Coega, where it is possibly now locally extinct due to extensive habitat loss and degradation, but may also be overlooked. Then it is known from a single, highly disjunct record from hills north-west of Grahamstown. It is not known whether this is an aberrant record, or whether the population is continuous between Uitenhage and Grahamstown. It may be overlooked, as this area is botanically relatively poorly sampled.
