The best known and most popular indigenous useful plants in the Agter–Hantam are Aloe microstigma (a new species record, with a SPI of 0.97), Hoodia gordonii (SPI = 0.94), Microloma sagittatum (0.94), Sutherlandia frutescens (0.92), Quaqua incarnata (0.92) and Galenia africana (0.85). In the Agter–Hantam, the EKI varied from 0.20 to 0.93 in older people but even young children had EKI values of 0.27. This article also introduces two new terms - the Ethnobotanical Knowledge Index (EKI), a quantitative measure of a person's knowledge of local plant use (value between 0 and 1), and the Species Popularity Index (SPI), a quantitative measure of the importance or popularity of each species (value between 0 and 1). The data include 14 new species records of useful plants 20 new vernacular names and 99 new uses for 46 of the plant species, showing that Khoi–San ethnobotany is still incompletely recorded and that there is an urgent need to document this wealth of traditional knowledge before it is lost forever. tentaculata, S - Tromotriche aperta, U - Anomalluma mccoyi, V - Stapeliopsis neronis, W - Hoodia spec. hottentotorum Quaqua inversa Quaqua marlothii Quaqua multiflora Quaqua parviflora subsp. pilifera Quaqua aurea Quaqua cincta Quaqua confusa Quaqua framesii Quaqua incarnata subsp.

family: Asclepiadaceae subfamily: Asclepioideae tribe: Stapelieae. The use of a rapid appraisal methodology, followed by a new approach that we refer to as the Matrix Method, has revealed a wealth of traditional knowledge on useful plants amongst people of Khoi–San decent in the Agter–Hantam, Calvinia district, Northern Cape Province of South Africa.
