Thunberg (1794) had knowledge of seven stapeliads belonging to different genera, but the first Duvalia species were described by Masson (1796) with Stapelia caespitosa, S. elegans and S. reclinata. Based on these three taxa Haworth (1812) established the genus Duvalia, adding Sims’ (1803) S. radiata, and described D. compacta, D. glomerata, D. laevigata and D. tuberculata as new. Haworth’s new genus was named in honour of H.A. Duval, a French botanist, who previously named Haworthia in the Liliaceae.
