| Description | Background: The Rhynchosia totta complex is one of three taxonomically complicated African groups in the genus Rhynchosia. Numerous southern African species and infraspecific taxa (at least 19 names, 17 species and 2 varieties) have been described by various authors in the past, but were later reduced into synonymy with R. totta. Currently, only the typical variety is recognised in Southern Africa.Objectives: To investigate and update the circumscription of the taxa within the R. totta complex in southern Africa and to update their synonymies and distribution ranges. Methods: Specimens of R. totta at GRA, JRAU, K, NH and PRE were studied and compared, and measurements of characters recorded. Populations were also observed during field studies.Results: The examination of numerous specimens, as well as field investigations, has prompted the recognition of four varieties (one described here as new: R. totta var. longicalyx) and a new species (R. pedunculata) in southern Africa.Conclusions: A great variation in leaf structure and vestiture occurs within the R. totta complex, with the extreme forms easily recognisable. However, the total number of varieties are limited to four [R. totta vars. totta, longicalyx, rigidula and venulosa] and a new species described to accommodate specimens with a distinctly prostrate habit and upwardly directed leaves. | |
