In the preparation of the series issued of the " Flowers and Ferns of the United States," the author gave the geographical ranges and other facts so far as the information then at command would permit. The following plants were then only known to the author as being found east of the Mississippi. A St. Louis correspondent finds them now west of the river: Polypodium incanum and Asplenium tri-chomanes, on rocks, St. Louis county, Mo.; along Meramec river, three miles west of Allenton; Rosa Carolina, in swamps, Butler county, Southeast Missouri; Carex stricta, in woods about Allenton, Mo.; Orchis spectabilis, shady, grassy places, Allenton, Mo., scarce; Collinsonia Canadensis, Iron county, Mo.; Asplenium parvulum, Hot Springs, Ark.; Lysimachia quadrifolia, damp woods, Allenton, Mo.; Rhexia Virginica, low grounds Southeast Missouri and Little Rock, Ark.; Silene Virginica, Jackson county, Ark.; Arteme-sia plantaginifolia, on flinty hills and upland sandy woods, Allenton, Mo., abundant; Vitis indivisa, from Allenton, Mo., Dallas, Texas, south to Arkansas also.
