Studies in the vascular flora of the southeastern United States: V
2019
As part of ongoing efforts to understand and document the flora of the southeastern United States, we propose a number of taxonomic changes. In Trichostema, we name a new species, narrowly endemic to maritime grasslands in the Carolinas and warranting formal conservation status and action. In Dichanthelium (Poaceae), we continue the reassessment of taxa formerly recognized in Panicum and provide new combinations along with a new key to taxa in the Dichanthelium scabriusculum complex. In Paspalum (Poaceae), we address the controversial taxonomy of P. arundinaceum and P. pleostachyum and treat the two as conspecific, with P. arundinaceum the correct name. In Portulaca (Portulacaceae), we report the discovery of the Bahamian P. minuta as a native component of the North American flora, occurring in southern Florida. resumen Como parte de los esfuerzos en marcha para entender y documentar la flora del sureste de Estados Unidos, proponemos un número de cambios taxonómicos. En Trichostema, nombramos una especie nueva, endemismo restringido a las praderas marinas en las Carolinas y que justifica un estatus formal de conservación y acción. En Dichanthelium (Poaceae), continuamos la reconsideración de taxa reconocidos previamente en Panicum y hacemos combinaciones junto con una nueva clave para los taxa en el complejo Dichanthelium scabriusculum.

In some cases, new combinations are needed to accurately reflect current taxonomic understanding. Some of these reflect rank This document is intended for digital-device reading only.

The Vascular Flora of Lauderdale County, Mississippi, U.S.A
Rhodora, 2011
A floristic survey of Lauderdale County, Mississippi was undertaken from the spring of 2004 through the fall of 2009 in order to document the flora and describe plant communities from this poorly studied region within Mississippi. A total of 1175 vascular plant species (1206 taxa altogether, including species and infraspecific taxa) was recorded from the county. Oenothera sinuosa and Geranium molle were collected for the first time in the state of Mississippi, and Carex breviculmis was recorded from North America for the first time. One hundred and eighty-six introduced species were recorded in the county. Forty-seven rare and uncommon species, according to the Mississippi Natural Heritage Program special plant tracking and watch lists, were recorded from Lauderdale County and many range extensions and species disjunctions were discovered. We describe nine primary plant communities in the county and discuss the biogeographical importance of the flora of Lauderdale County relative to the rest of the state.
Studies in the vascular flora of the southeastern United States. IX
Journal of the Botanical Research Institute of Texas, 2023
As part of ongoing work on the Flora of the Southeastern United States (Weakley & Southeastern Flora Team 2022a) and related projects, as well as for general floristic, conservation, and scientific work in eastern North America, it is essential to document taxonomic and nomenclatural changes and significant distribution records. Here we describe three new species (in Rhynchospora, Sabulina, and Solidago), describe a new section (in Trichostema), make new combinations to treat taxa at appropriate ranks in appropriate genera and with appropriate nomenclatural application based on types (in Lycopodioides, Moeroris, Morella, Nellica, Tamala, and Trichostema), and propose the lumping of two species, resulting in a change in name and nativity status (in Sisyrinchium). These new combinations (rank changes, or generic transfers to apply newly accepted generic concepts to taxa that do not have corresponding available names at the appropriate rank) are needed to accurately reflect current taxonomic understanding of the regional flora. In the course of doing so, we discuss and address various nomenclatural issues, including typifications, and clarify characters and identification of difficult groups (providing new keys) in the regional flora. We also report significant new distribution and naturalization records in many genera, in New Jersey (taxa in the genera

Journal of the Botanical Research Institute of Texas, 2020
As part of ongoing efforts to understand, document, and conserve the flora of southeastern North America, we propose a number of taxonomic changes, nomenclatural changes, interpretations of nativity, and distributional accounts. Regarding the Asaroideae (Aristolochiaceae), we support continued recognition of Hexastylis (and other segregates of a very broad Asarum s.l.) at generic rank and make the necessary combinations to continue the use of Hexastylis in southeastern North America floras. In Conoclinium (Asteraceae), we present morphological and distributional evidence corroborating the recent suggestion (based on molecular evidence) that Chapman’s 1878 C. dichotomum is distinct, warrants recognition, and is present as a second Conoclinium in the southeastern North American flora. An analysis of historical accounts of Gaillardia pulchella (Asteraceae) strongly suggests that its modern occurrence east of Texas is adventive, rather than native. Two rare southeastern United States sk...
Vascular Flora of Hugo Lake Wildlife Management Area, Choctaw County, Oklahoma
Southeastern Naturalist, 2004
This paper reports the results of an inventory of the vascular plants at the Hugo Wildlife Management Area in southeastern Oklahoma. A total of 573 specific and interspecific taxa of vascular plants in 359 genera and 113 families were collected. The most commonly collected were of the families Poaceae (75), Asteraceae (76), Fabaceae , and Cyperaceae (38). One hundred sixty-four species were annuals or biennials, and 409 were perennials. Ninety-seven species of woody plants were present. Fifty-one exotic species were collected representing 9% of the flora. Fourteen species tracked by the Oklahoma Natural Heritage Inventory were found. This study reports 256 species previously not documented in Choctaw County. Vol. 3, No. 4 704 The 11 collection sites at HWMA occurred within five vegetation associations. A brief description of each follows:
Proceedings of the Indiana Academy of Science, 2002
This paper on Wilbur Wright Fish and Wildlife Area (WWFWA), Henry County, Indiana, documents 635 vascular plant species and varieties within the 416.6 ha (1029 acre) site. The 635 species and varieties represent 343 genera and 109 families with the Asteraceae (76 species), Cyperaceae (55 species including 44 Carex spp.) and Poaceae (53 species) having the highest number of species. Unusual sedges include Carex atherodes and Carex gravida. A total of 274 species is recorded for the first time from Henry County. Of the 61 1 angiosperms listed, 163, or approximately 27%, are non-native or exotic species. The vascular flora of WWFWA includes one rare species (Rudbeckia fulgida var. fulgida [in prairie plantings]), two endangered species (Epilobium ciliatum and Zannichellia palustris), two threatened species (Thalictrum pubescens and Veronica anagallis-aquatica) and four species on the watch list (Filipendula rubra, Panax quinque'folium, Spiranthes oralis and Synandra hispidula) compiled by the Indiana Natural Heritage Program. The physical and biotic history of the site is reviewed, and the major community types (upland forest, floodplain forest, wetlands, aquatic and successional) are described.
The Vascular Flora of Hale Scout Reservation, LeFlore County, Oklahoma
Oklahoma Native Plant …, 2011
The Hale Scout Reservation is located in the Ouachita Mountains of southeastern Oklahoma, a region of high plant diversity in the state. A vascular plant inventory yielded 463 species of vascular plants in 288 genera and 99 families. The largest families were the Asteraceae (with 65 species) and Poaceae (56). The flora consisted of 120 annuals, 1 biennial, and 342 perennials. Forty-two non-native species were collected, representing 8.8% of the flora. Sixteen species tracked by the Oklahoma Natural Heritage Inventory were present: Amorpha ouachitensis (S1), Aristolochia serpentaria (S1), Baptisia nuttalliana (S2), Brachyelytrum erectum (S1), Brasenia schreberi (S1), Carex ouachitana (S1), Chionanthus virginicus (S2), Clematis crispa (S1), Didiplis diandra (S1S2), Galium arkansanum (S2), Houstonia ouachitana (S1), Juncus repens (S1), Modiola caroliniana (S2), Monotropa hypopithys (S1), Muhlenbergia bushii (S1), and Ribes cynosbati (S2) (Oklahoma Natural Heritage Inventory, 2010).
