ABSTRACT The following recently discovered vascular plants are new records for the State of West Virginia, U. S. A.: <em>Eulalia uiminea</em> (Trin.) Ktze., <em>Rubus plicatifolius</em> Blanchard, <em>Rubus elegantulus</em> Blanchard, <em>Vicia tetrasperma</em> (L.) Moench, <em>Lysimachia thyrsiflora</em> L., <em>Fraxinus americana<em> forma <em>iodocarpa</em> Fern., <em>Phlox glaberrima</em> L., <em>Teucrium botrys</em> L., <em>Dipsacus laciniatus</em> L., <em>Knautia arvensis</em> (L.) Duby., and <em>Aster ontarionis</em> Wieg.
ABSTRACT Topography, climate, edaphology, and vegetation of Presquile, a James River island in Chesterfield County, Virginia, are considered in this study. A brief history of the island is provided. Seven soil types occurring on the island are described. Plant communities are classified as river escarpment, fill, swamp, marsh, and field border, and each is described. Species characterizing each community are given. A map of the island showing habitats is included.
ABSTRACT <em>Arctium minus</em>, <em>Centaurea</em>, with seven species, and <em>Cnicus benedictus</em> are treated floristically for Virginia. Keys to genera and species, along with species descriptions, distribution maps, ecological and flowering and fruiting data are included. <em>Centaurea</em> X <em>pratensis</em> is reported new to the flora.
ABSTRACT Studies on the vascular flora of the northwestern Highland Rim of Middle Tennessee have resulted in several additions to the State flora and numerous range extensions within the State. An annotated list includes 16 new or verified taxa for the State, 47 range extensions within the State, and 6 county records for species rarely found in Tennessee.
ABSTRACT Studies of plant succession on three abandoned Tennessee Valley Authority “fly ash pits” in Middle Tennessee were made using the quadrat method of sampling. The pits varied in age from 6 months to 8 years. Dominants occurred in the following sequence: pit I (6 months), <em>Polygonum pensylvanicum</em> and <em>Paspalum pubiflorum</em>, with phenotypic dominants being <em>Erigeron canadensis</em> and <em>Bromus inermis</em>; pit II (3 years), <em>Bromus inermis</em> and <em>Pyrrhopappus carolinianus</em>, with phenotypic dominants being <em>Bromus inermis</em>, <em>Andropogon virginicus</em>, and <em>Populus deltoides</em>; pit III (8 years), <em>Solidago</em> spp. and <em>Melilotus</em> alba, with the phenotypic dominants being the two former taxa plus <em>Populus deltoides</em>, <em>Salix interior</em>, and <em>Salix nigra</em>. Since no studies of this specific nature have been carried out in the past, comparisons of vegetational responses are difficult to make. The data on plant succession recorded on the “fly ash pits” is considerably different from past studies on abandoned cropland in Middle
ABSTRACT Keys, distributions, taxonomic and nomenclatural notes are given for the seven species of Anemone native to the southeastern United States. The name <em>Anemone berlandieri</em> Pritzel is recognized in place of <em>A. heterophylla</em> Nutt. ex Torr. & Gray.
