Marasmodes reflexa

Taxonomy
Scientific Name
Marasmodes reflexa S.Ortiz
Higher Classification
Dicotyledons
Family
ASTERACEAE
National Status
Status and Criteria
Critically Endangered (Possibly Extinct)

Justification
This species was last recorded in 1946, and since then, most of its renosterveld habitat has been converted to crop fields. Surveys to relocate surviving subpopulations are ongoing, but have thus far been unsuccessful. This species is possibly extinct.

Description
Shale renosterveld.
Threats
Land transformation for crop cultivation and to a lesser extent, urban expansion, has caused extensive loss of this species' renosterveld habitat, and currently only small fragments remain. Remaining natural vegetation is being continually degraded due to overgrazing and invasive alien plant infestations.
Population

Marasmodes reflexa was first collected in 1946, from an unspecified locality in renosterveld near Napier. It has not been recorded since. In 2011 and 2016, volunteers of the Custodians of Rare and Endangered Wildflowers (CREW) programme surveyed remaining renosterveld fragments for this species, but failed to locate any surviving subpopulations. It is however possible that it may be overlooked, as Marasmodes species are cryptic and localized to specialised, often transitional habitats. The species is possibly extinct, as very little renosterveld remains intact in the area where it was last recorded, but more surveys are needed to confirm this.
