|discussion=<p><i>Lysimachia clethroides</i> has been reported from Quebec, apparently as an adventive.</p><!--
--><p><i>Lysimachia clethroides</i> is similar to another introduction from eastern Asia, the Manchurian loosestrife, L. barystachys Bunge. The latter is known in the flora area only from Clarke County, Georgia; it may be expected elsewhere; floral features are similar to those of <i>L. clethroides</i>; the two differ in vegetative features. <i>Lysimachia</i> barystachys has linear-elliptic to lanceolate or narrowly ovate leaf blades; <i>L. clethroides</i> has broadly elliptic to lanceolate or broadly ovate leaf blades. Reports of differences in floral length (J. D. Ray 1956) appear to be erroneous; J. Ohwi (1965) indicated that L. barystachys has corollas 7–12 cm in diameter versus 8–12 cm in <i>L. clethroides</i>; I have found dried garden flowers of <i>L. clethroides</i> measuring 7.5–10 cm.</p>
