ABSTRACT Three species of non-native vascular plants are reported here as new to Alabama. Persicaria capitata (Buch.-Ham. ex D. Don) H. Gross, Pistacia chinensis Bunge, and Sedum diffusum S. Watson are all species cultivated as ornamentals, and likely represent escapes from nearby plantings. Recent collections of three non-native species in Alabama represent the first documented examples of these taxa as naturalized elements of the state's flora. In each case, the taxon was not included in the most recent statewide comprehensive publications including the Annotated Checklist of the Vascular Plants of Alabama (Kral et al. 2011) and the Alabama Plant Atlas (Keener et al. 2021). Additionally, Weakley (2020) did not include Alabama within the known distributions for each of them, and searches of BONAP (Kartesz 2020) and SERNEC (2021) failed to locate any additional non-cultivated specimens from Alabama.
本文报道了三种非本地维管植物为阿拉巴马州的新植物。桃金娘;例如D. Don) H. Gross, Pistacia chinensis Bunge和Sedum diffusum S. Watson都是作为观赏植物栽培的物种，可能代表从附近的植物中逃逸出来。最近在阿拉巴马州收集的三种非本地物种代表了这些分类群作为该州植物区系归化元素的第一个有记录的例子。在每种情况下，分类群都没有被包括在最新的全州综合性出版物中，包括阿拉巴马州维管植物注释清单(Kral等人，2011年)和阿拉巴马州植物图集(Keener等人，2021年)。此外，Weakley(2020)没有将阿拉巴马州包括在已知的分布中，BONAP (Kartesz 2020)和SERNEC(2021)的搜索未能找到任何来自阿拉巴马州的其他非栽培标本。

ABSTRACT Ludwigia ravenii is a critically imperiled tetraploid known historically from Virginia to Florida. There have been no published studies examining the number of seeds produced per capsule to guide researchers and conservationists in planning studies or collection efforts. Such data are important considering current guidelines by the Center for Plant Conservation recommend that no more than 10 percent of a population's seed production be collected in a single season. To fill this void, our objective was to examine and report on capsule-seed allometric relationships in the species. Our study is based on 25 capsules from six plants from the North Carolina Coastal Plain. Though admittedly limited in geographic scope, we focused on these wild plants to avoid destruction of herbarium specimens and as they were already the subject of a broader, permitted inquiry into seed germination. Consistent with prior, range-wide monographic study, measured capsule dimensions were: length 2.87–5.41 mm (mean=3.98, sd=0.64); broader facet width 1.95–3.67 mm (mean=2.94, sd=0.43); narrower facet width 1.88–3.27 mm (mean=2.70, sd=0.39). The mean number of seeds produced per capsule was 304.8 (sd=94.9). The mean number of seeds produced by capsules at least 4 mm long was 361 (sd=65.7), whereas the mean number of seeds produced by capsules less than 4 mm long was 233 (sd=77.8). In the absence of additional data from other populations, we preliminarily recommend that capsule collection efforts focus on capsules at least 4 mm long.

ABSTRACT Yellowroot (Xanthorhiza simplicissima Marshall, Ranunculaceae) is a low-growing deciduous shrub native to hardwood forests in the eastern United States. This review synthesizes existing knowledge about yellowroot's natural and cultural history including traditional uses, contemporary applications, and future implications. Emphasis is placed on the southern Appalachian mountain region, which is the core of its cultural importance. Natural history and ethnobotanical knowledge about yellowroot were collected from published literature, oral histories, and field observations. While it was first described by botanists in the 18th Century, yellowroot was already a well-established and culturally significant plant to the Native peoples of southern Appalachia for centuries. At least 34 Indigenous medicinal and craft uses are documented, confirming that yellowroot was, and to an extent still is, a culturally significant plant for Indigenous people in the southern Appalachian region. European and African American settlers to the region also incorporated the plant into many of their folk traditions, and wild harvesting and cultivation continues to this day. Modern analytical techniques have identified key phytoactive compounds in yellowroot extracts, lending credence to its traditional medicinal uses and potential applications in modern medicine.

ABSTRACT In 2013, a new species of clover endemic to Kentucky was described. This species, Trifolium kentuckiense (Fabaceae), has yet to be placed in a phylogeny but is hypothesized to be most closely related to T. reflexum based on morphology. We present phylogenetic evidence from the nuclear (ITS) and plastid genomes (trnL and ndhA introns) that T. kentuckiense is a member of a clade of seven Trifolium species native to eastern North America. Within this clade, T. kentuckiense is strongly placed in a clade with three other annual/biennial Trifolium species (T. bejariense, T. carolinianum, and T. reflexum); it is sister to T. reflexum, although support for this relationship is weak. Our results support previous findings that suggest the ndhA intron is much more variable than the trnL intron in the Eurosid I clade. The ndhA intron contained over twice the number of parsimony informative characters when compared to the trnL intron, though ITS was more variable than either region. We also provide a dichotomous key to native and nonnative members of Trifolium for Kentucky and its surrounding states. We suggest determinations of historic specimens of Trifolium, particularly those identified as T. reflexum, be reassessed to obtain localities that may still support populations of this recently described species. We also provide guidance on when and in what habitats to search for new populations of this extremely rare taxon.

ABSTRACT Non-native and invasive (NNI) plants have spread throughout the southeastern United States. To monitor the spread of NNI plants and implement appropriate management we need to understand the relationship between NNI plants and their avian dispersers. Birds are the primary disperser of many NNI plants, and thus a thorough understanding of their role can aid agencies wishing to control the spread of NNI plants. We examined the literature to assess the current knowledge of the relationship between NNI plants, specifically shrubs, trees, and vines, and their avian dispersers in the southeastern United States. We found 56 papers covering 28 NNI plant species and 46 bird species. 66% of papers on NNI plants did not connect plants with specific avian dispersers and those that did tended to mention fewer than five avian species. More studies were conducted in Florida than any other state and most papers focused on the spread of NNI plants. Our review indicates a need for further research to identify the avian dispersers of NNI plants and the role they play in the spread of NNI in the southeast.

ABSTRACT The Christmount Preserve is a botanically diverse and ecologically rich area of approximately 155 ha of southern Appalachian forest held in conservation easement. We conducted a floristic inventory of the preserve to inform conservation efforts on the property. Although the plant diversity within the preserve is an important attraction for residents and visitors, information on its flora is limited. This study builds upon a brief but informative 1996 report of the North Carolina Natural Heritage Program summarizing the preserve's attributes as a natural area. A total of 317 specimens of vascular plants were collected during 2018–2020 to develop a vouchered flora of the preserve. These specimens documented 221 species in 165 genera and 84 families, 4.5% of which are not native to the Appalachian Mountain region. We found three plant taxa that are listed by the North Carolina Natural Heritage Program: Coreopsis latifolia, Hypericum buckleyi, and Robinia hispida var. fertilis. Plant community types found on the property include large areas of Rich Cove Forest, Acidic Cove Forest, and Montane Oak-Hickory Forest, but also included small patches of Pine-Oak/Heath–High Elevation Subtype, a globally imperiled plant association, along the high ridgelines. The information presented here will be used to help guide management efforts as well as educational programming by the managing organization, Christmount Christian Association (CCA).
摘要基督山保护区是一个植物多样、生态丰富的地区，拥有约155公顷的阿巴拉契亚山脉南部森林，属于保护地役权范围。我们对保护区进行了植物区系调查，为保护区的工作提供信息。尽管保护区内的植物多样性对居民和游客来说是一个重要的吸引力，但有关其植物区系的信息有限。这项研究建立在1996年北卡罗来纳州自然遗产计划的一份简短但信息丰富的报告的基础上，该报告总结了保护区作为一个自然区域的属性。2018-2020年间，共收集了317个维管植物标本，以开发保护区的担保植物群。这些标本记录了84科165属221种，其中4.5%不是阿巴拉契亚山区的本地物种。我们发现了三个被北卡罗来纳州自然遗产计划列入名录的植物分类群：宽叶紫草、金丝桃和长叶Robinia hispida var.ffertilis。在该地产上发现的植物群落类型包括大面积的Rich Cove森林、Acidic Cove森林和Montane Oak Hickory森林，但也包括沿着高山脊线的小块松橡树/希思-高海拔亚型，这是一种全球濒危的植物群落。这里提供的信息将用于指导管理组织基督山基督教协会（CCA）的管理工作和教育计划。

ABSTRACT The current cycle of global warming has contracted some range restricted species while concurrently expanding the range of more adaptable species. Sabal minor is a member of Arecaceae, the palm family, and is confined to lower latitudes in both western hemispheres. Latitudinal limitation of S. minor is believed to be related to low temperature intolerance. However the exact mechanism remains elusive. In this study reproductive fecundity of anthropogenically introduced populations in southern Virginia Beach, Virginia, was evaluated. Diaspore viability, approximated by floatability of fruits, was used to evaluate distribution by hydrochory. This study also documents a previously unidentified condition of fungal mass growth around the fruits of S. minor during buoyancy testing and suggests some areas for additional investigation.

ABSTRACT Limestone cedar glades, one of the rarest ecosystems in the world, are home to several uncommon species, including Trifolium calcaricum (Fabaceae), the running glade clover. Due to habitat destruction and fragmentation, the states of Tennessee and Virginia have listed T. calcaricum as an endangered species. To preserve T. calcaricum and increase its numbers, a reintroduction effort was initiated in 2016 in which individual plants were transplanted from a source site to secondary locations at Cedars of Lebanon State Park and Vesta Cedar Glade State Natural Area in Tennessee. In the current project, the extent of clonality among transplanted individuals was assessed using fluorescently tagged inter-simple sequence repeat (ISSR) markers. Sampled individuals were determined to be moderately clonal, with 46 sampled ramets representing 14 unique genets, with the estimated size of the largest genet being approximately 100 meters across. We provide baseline data for this understudied species and provide context for future work.
