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.","PeriodicalId":50984,"journal":{"name":"Castanea","volume":"86 1","pages":"278 - 282"},"PeriodicalIF":0.4,"publicationDate":"2022-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45601078","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":50984,"journal":{"name":"Castanea","volume":"86 1","pages":"151 - 172"},"PeriodicalIF":0.4,"publicationDate":"2022-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43702018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":50984,"journal":{"name":"Castanea","volume":"86 1","pages":"283 - 295"},"PeriodicalIF":0.4,"publicationDate":"2022-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44651057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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).","PeriodicalId":50984,"journal":{"name":"Castanea","volume":"86 1","pages":"185 - 195"},"PeriodicalIF":0.4,"publicationDate":"2022-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46753116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
