Thesium fallax Schltr.
Status and Criteria
Data Deficient - Insufficient Information
|L. von Staden|
|A range-restricted and poorly known species that is possibly threatened by competition from alien invasive plants. It was last recorded in 1896, and not enough is known about its distribution range, population status and trends to determine its risk of extinction.|
|South African endemic|
|Mountains between Bredasdorp, Napier, and Elim.|
Habitat and Ecology
|Overberg Sandstone Fynbos|
|Uncertain, possibly sandstone slopes.|
|This species is possibly threatened by competition from alien invasive plants. Large areas of the Elandskloof and Bredasdorp Mountains are infested with alien invasive plants.|
This species is known from only a few, very old collections with imprecise locality details. It appears to be endemic to the Bredasdorp and Elandskloof mountains (Manning and Goldblatt 2012), but it may be more widespread and overlooked elsewhere. The genus Thesium is very poorly known, and in need of taxonomic revision. Confusion with other taxa may therefore also explain the lack of recent records.
