Discussion | The name Lespedeza violacea was widely applied to L. frutescens in the past; however, the type specimen of the basionym (Hedysarum violaceum) represents the species previously called L. intermedia. The result is that the name L. violacea replaces what was called L. intermedia, and L. frutescens must be taken up for this species (J. L. Reveal and F. R. Barrie 1991). Lespedeza frutescens forms natural hybrids with L. capitata, L. hirta, L. procumbens, L. repens, L. stuevei, L. violacea, and L. virginica. Hybrids with L. violacea are common (A. F. Clewell 1966) and have been called L. × acuticarpa Mackenzie & Bush. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
The name Lespedeza intermedia has traditionally been used for plants here called L. violacea (J. L. Reveal and F. R. Barrie 1991). The species that previously was called L. violacea is now L. frutescens. Lespedeza violacea forms natural hybrids with L. capitata, L. frutescens, L. hirta, L. procumbens, L. repens, L. stuevei, and L. virginica.
