This Chinese species is often confused with barbarum, as reflected in nomenclatural history, and some authors have combined the two species (Cr, J). The only verified records from Ky. are colls. from JEFF (MM # 18084-87 at WKY) and MEAD (herbarium of Ind. Univ. SE). L. chinense has corolla lobes longer than the tubes (versus shorter); its leaves are bright green (versus gray green), relatively short (ca. 2-5 cm versus 3-8 cm) and widest below the middle (versus at the middle).
