C. F. Millspaugh, in his “Flora of West Virginia” (1892), p. 401, reported Kalmia angustifolia L. from Calhoun, Upshur, Nicholas, Randolph, and Hardy counties, West Virginia. Specimens from his collections, however, were apparently misidentified and actually represented Kalmia latifolia L. P. D. Strausbaugh and Earl L. Core, in their “Flora of West Virginia” (2nd ed., p. 714), concluded that Millspaugh’s listing of K. angustifolia was “through error.”
