Discussion | Subspecies 2 (2 in the flora). Lespedeza hirta forms natural hybrids with L. angustifolia, L. capitata, L. frutescens, L. procumbens, L. repens, L. stuevei, L. violacea, and L. virginica. Hybrids with L. violacea have been called L. × nuttallii Darlington, and offspring from Indiana plants of L. × nuttallii show morphologies that range from one parental species to the other. Other purple-petaled species may hybridize with L. hirta to produce offspring similar to the morphology of L. × nuttallii (D. Isely 1998).

Subspecies hirta ranges from New England, southern Ontario, southern Michigan, and eastern Oklahoma, to central Florida and eastern Texas; it is rare on the sandy soils of the Atlantic Coastal Plain (A. F. Clewell 1964). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
