ABSTRACT Morphometric data were used to investigate the relationship between Cyperus squarrosus and related C. granitophilus, with particular attention to populations of C. granitophilus recently reported from granite outcrops in Texas and Oklahoma. Data for 23 characters (variables) taken from 406 voucher specimens were analyzed using principal component analysis (PCA), discriminate analysis (DA), multivariate analysis of variance (MANOVA), and a Euclidian distance dendrogram. Results (1) strongly support the treatment of C. granitophilus and C. squarrosus as separate species but (2) provide at best weak evidence for formal recognition of C. squarrosus var. runyonii and (3) indicate that the Texas and Oklahoma populations recently reported as C. granitophilus are more closely related to C. squarrosus than C. granitophilus.
摘要形态计量学数据用于研究莎草和相关的亲花岗岩类之间的关系,特别是最近从德克萨斯州和俄克拉荷马州的花岗岩露头中报道的亲花岗岩种群。使用主成分分析(PCA)、判别分析(DA)、多变量方差分析(MANOVA)和欧氏距离树状图分析了406份凭证样本中23个字符(变量)的数据。结果(1)强烈支持将C.grantisophilus和C.squarosus作为单独的物种处理,但(2)为正式承认C.squarousvar.runyonii提供了充其量是微弱的证据,以及(3)表明最近被报道为C.grantisiphilus的得克萨斯州和俄克拉荷马州种群与C.squarous的亲缘关系比C.grantistophilus更密切。

ABSTRACT A floristic checklist of vascular plants was conducted at Shenandoah River State Park (SHSP) in Bentonville, Virginia during the 2021 and 2022 growing seasons. SHSP encompasses 665 hectares (1619 acres) of the northern Shenandoah Valley between the Massanutten Mountains and Shenandoah National Park. The park lies in Warren County which has been botanically underexplored, consistently ranking last in plant collection metrics among the five northern Shenandoah Valley counties. SHSP contains 11 community types that span 165–296 meters above sea level from inland wetlands and river scour communities to upland forests, including endemic Central Appalachian Shale Barrens. A total of 797 collections yielded 536 unique taxa from 109 vascular plant families. These collections were secondarily extended with in-field pictures that were aggregated on an iNaturalist project page. Quick Response (QR) codes were used to link herbarium vouchers to their respective iNaturalist entry. Sixty-four county records of taxa not yet observed in Warren County and one state record, Equisetum laevigatum, were documented. As a first for SHSP, this floristic checklist provides baseline botanical knowledge of the park and expands the available digital data of vascular plants for Warren County by 20%. This augmented knowledge, in tandem with the accompanying iNaturalist project page, will not only be useful to park managers for future development and conservation plans but will also serve as a tool for community scientists to enhance their knowledge of the local flora.
在2021年和2022年的生长季节,对弗吉尼亚州本顿维尔的谢南多阿河州立公园(SHSP)的维管植物区系进行了检查。SHSP占地665公顷(1619英亩),位于马萨努滕山脉和谢南多厄国家公园之间的谢南多厄山谷北部。该公园位于沃伦县,在植物学上一直未得到充分开发,在谢南多厄山谷北部五个县的植物收集指标中一直排名最后。SHSP包含11种群落类型,跨越海拔165-296米,从内陆湿地和河流冲刷群落到高地森林,包括特有的阿巴拉契亚中部页岩贫瘠地。共收集797个标本,鉴定出109个维管植物科的536个独特分类群。这些收藏在iNaturalist项目页面上汇总了实地照片,并进行了二次扩展。我们使用快速响应码将植物标本馆券与各自的innaturalist条目链接起来。记录了沃伦县尚未观察到的64个县的分类群记录和一个州的分类群记录,laevigatum。作为SHSP的第一个项目,该植物区系清单提供了公园的基本植物学知识,并将沃伦县维管植物的可用数字数据扩展了20%。这些增加的知识,连同附带的iNaturalist项目页面,不仅对公园管理者未来的发展和保护计划有用,而且还将成为社区科学家提高他们对当地植物群知识的工具。

ABSTRACT An inventory of the botanical resources of Doe Mountain Recreation Area, comprising 3480 ha on the boundary of the Blue Ridge and Ridge and Valley ecoregions in extreme northeastern Tennessee, was conducted to help guide conservation-based management. A total of 486 species (including subspecies and varieties) was found comprising 95 families, 286 genera, 11 species tracked on the state rare plant list, 153 county records, and 77 exotic species. The relatively high ratio of county records to exotics indicated an area of conservation merit, but the ratio was lower than in floras from comparable areas in eastern Tennessee. The vast majority of county records were of common species, suggestive of an under-collected county. However, some of the noteworthy county records and state-listed species were from unusual habitats such as acid seeps, wetlands, and xeric ridges. Two species, Liatris virgata and Lycopodiella inundata, were new to the state. Water in the seep that supports L. inundata was an order of magnitude more acidic (pH=3.56) than at other sites. An analysis of the wildland–urban interface showed that the periphery of the site had more human impact than the county as a whole with the highest impact on the northern half; only 13% of the area was classified as uninhabited. Management recommendations, some of which were already adopted, targeted protection of acid seeps and xeric roadside slopes, curtailing mowing and herbicide use near a wetland that supports a state endangered species, and reconnaissance for exotic invasions in a biodiverse power line corridor.
摘要对美国田纳西州东北部蓝岭和岭谷生态区边界上3480公顷的多伊山游乐区进行了植物资源清查,以指导保护区管理。共发现486种(含亚种和变种),分属95科286属,国家珍稀植物名录11种,县记录153种,外来种77种。县记录与外来植物的比例较高,表明该地区具有保护价值,但该比例低于田纳西州东部可比地区。绝大多数的县记录是常见的物种,暗示了一个未被收集的县。然而,一些值得注意的县记录和国家列出的物种来自不寻常的栖息地,如酸性渗漏,湿地和干旱山脊。2种为该州新种,分别为Liatris virgata和Lycopodiella淹没。与其他地点相比,支持水蛭生长的渗漏水的酸性(pH=3.56)要高一个数量级。对野地-城市界面的分析表明,基地外围的人文影响大于整个县,其中北半部的人文影响最大;只有13%的地区被列为无人居住。管理建议,其中一些已经被采纳,有针对性地保护酸渗漏和干燥的路边斜坡,减少在支持国家濒危物种的湿地附近修剪和除草剂的使用,以及对生物多样性电力线走廊的外来入侵进行侦查。

ABSTRACT Rhododendron eastmanii is a species endemic to South Carolina and common in the Enoree Ranger District of the Sumter National Forest. A four-year study was undertaken to revisit known populations and to locate new populations. A total of 2,035 individuals in 38 populations were documented, including 663 seedlings, 705 non-flowering adults, and 667 flowering individuals. Plants were most commonly found on mature hardwood slopes above headwater streams. Pollinator visitors included eastern tiger swallowtail (Papilio glaucus), pipevine swallowtail (Battus philenor), and bumblebees (Bombus spp.). Concerns for the future of the species were noted due to deer browsing and subcanopy shading, especially from Acer leucoderme (a native tree) and Elaeagnus umbellata (an introduced shrub). This survey results in a better understanding of the species distribution and documents its demographic changes over time.
摘要东马尼杜鹃是南卡罗来纳州的特有种,常见于萨姆特国家森林的伊诺里游骑兵区。进行了一项为期四年的研究,以重新考察已知种群并确定新种群的位置。共记录了38个种群中的2035个个体,包括663个幼苗、705个非开花成虫和667个开花个体。植物最常见于上游溪流上方的成熟硬木斜坡上。来访者包括东方虎燕尾(Papilio glaucus)、胡椒燕尾(Battus philenor)和大黄蜂(Bombus spp。这项调查有助于更好地了解物种分布,并记录其随时间的人口变化。

ABSTRACT The prairie nymph, Herbertia lahue ssp. caerula, is a critically imperiled grassland plant in Mississippi. A large population of the prairie nymph occurs at the Vicksburg National Military Park. This population of prairie nymph occurs in a managed anthropogenic grassland with a host of associated native and exotic species. With the assistance of National Park Service staff an experiment investigating the effects of their mowing and a study of the growing conditions and pollinators of the plant was initiated. The mowing experiment was abandoned after two years because of the COVID-19 pandemic and yielded no significant results. Here we report on the growing conditions and associated species. The syrphid fly, Toxomerus marginatus, was observed to be a frequent flower visitor.
草原若虫(Herbertia lahue ssp.)小毛茛是密西西比州一种极度濒危的草原植物。维克斯堡国家军事公园里有大量的草原若虫。这个种群的草原若虫发生在一个管理的人为草原与宿主相关的本地和外来物种。在国家公园管理局工作人员的协助下,一项调查割草影响的实验开始了,一项关于植物生长条件和传粉媒介的研究也开始了。由于COVID-19大流行,割草实验在两年后被放弃,没有取得显著成果。这里我们报告生长条件和相关物种。据观察,边缘毒蝇(Toxomerus marginatus)是花上的常客。

ABSTRACT The vascular flora of Autauga County, Alabama, was surveyed from 2016 to 2020. A total of 168 families, 617 genera, 1,393 species, and eight named hybrids are reported. Of the 1,393 species, 1,097 were collected during this study and 296 are from the search of online databases. Thirty of the species are listed on The Inventory List of Rare, Threatened, and Endangered Plants and Animals of Alabama. Approximately 21.4% of the flora (298 species), are considered non-native. Families with the largest number of species and named hybrids were Asteraceae (162), Poaceae (147), Fabaceae (100), Cyperaceae (96), Rosaceae (42), and Lamiaceae (33).
