|discussion=<p><i>Spiraea lucida</i> has been considered a variety of S. betulifolia based upon: hypanthial vestiture, inflorescence shape, extent of leaf serration, and leaf texture (L. J. Uttal 1974); or, corymbiform inflorescences, white petals, plant nearly glabrous throughout (C. L. Hitchcock et al. 1955–1969, vol. 3; H. J. Scoggan 1978–1979, part 3; A. Cronquist et al. 1997). Although these character states occur in the eastern Asian S. betulifolia, it has very different leaf architecture showing much greater organization of the tertiary venation, which appears to be unique and is not found in any North American taxa. <i>Spiraea lucida</i> has an extremely variable leaf morphology that seems related to the tendency for stems to die back annually and the consequent annual production of long shoots. C. Sterling (1966) did not examine all taxa of <i>Spiraea</i>; the character states of carpel morphology of <i>S. stevenii</i> (see discussion there under) and <i>S. lucida</i> were reported to be similar and to differ slightly from those of S. betulifolia (the provenance of his specimen is not clear from the text).</p>
