Abstract
Plant invasions in South Africa: Insights from the 2017 National Status Report on Biological Invasions
Highlights
A comparison of the inventory with the Red List of South African plants showed a total of 15 edible plant species with conservation concerns
The method can be used to analyse the diversity and spatial patterns of useful plants by comparing the geographical distribution of each plant species with the geographical area of each of the 19 language/cultural groups that was reported to utilize the species. This new approach resulted in profound new insights into plant use patterns in southern Africa and provides a methodology that can be used beyond the field to ethnobotany to explore diversity patterns in a geographical context
The last comprehensive taxonomic revision of South African Thesium species was published by Hill in 1925 and is outdated
