--><p>In his revision of <i>Callaeum</i>, D. M. Johnson (1986c) cited a specimen of C. macropterum (de Candolle) D. M. Johnson, Palmer s.n. in 1869 (NY), as coming from Arizona, "without definite locality." That species occurs in Sonora, Mexico, fairly close to the U.S. border, but no other collection is known from north of the border. R. McVaugh (1956b) said that in 1869 Palmer collected in Arizona but was in southernmost Arizona only a short time; from Tucson he took a coach south into Sonora, where he collected in several areas, including the Yaqui River. There are two sheets of C. macropterum at NY labeled as Palmer s.n. in 1869, one with a label giving the locality as "Arizona," the other with a label giving the locality as "Yaqui River Sonora." The specimens look as if they were parts of the same gathering. Given McVaugh’s cautionary notes on the inaccuracies found in many of the labels placed on Palmer's collections after his return to Washington, I believe that the specimen cited by Johnson as coming from Arizona probably actually originated on the Yaqui River in Sonora, and am excluding C. macropterum from this treatment.</p>
