Justification
A poorly known species, last collected in the 1930s, but possibly overlooked, as the genus Drosanthemum is taxonomically problematic and in need of revision. It is likely to be in danger of extinction due to habitat loss to coastal development and agriculture, but until its distribution range and precise habitat requirements can be defined, its risk of extinction cannot be assessed.
Distribution
Endemism
South African endemic
Provincial distribution
Western Cape
Range
Mossel Bay, possibly occurring further west to Bredasdorp.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Fynbos
Description
Uncertain, possibly coastal areas.
Threats
Habitat loss to agriculture and coastal development are likely to be ongoing threats.
Population

This species is known from a few collections dating from the 1930s from the Mossel Bay area, but without precise localities. The genus Drosanthemum is in need of revision, and species are difficult to identify, and therefore this species may be overlooked. It is however highly likely to be in danger of extinction if it occurs on the coastal plains.
