Bwsr Featured Plant Minnesota's Milkweeds
BWSR FEATURED PLANT MINNESOTA’S MILKWEEDS Publication Date: 6‐1‐13 Milkweeds play a key role in wetlands, prairies, savannas and forests in Minnesota. The genus (Asclepias) is particularly important as a nectar and larval food source for a wide range of insect species. The best known example is the monarch butterfly whose larvae appear to feed only on milkweeds. Milkweeds have a unique pollination mechanism where pollen grains are enclosed in waxy sacs called “pollina” that attach to the legs of butterflies, moths, bees, ants and wasps and are then deposited in another milkweed flower if they step into a specialized anther opening. Most milkweeds are toxic to vertebrate herbivores due to cardiac glycosides that are in their plant cells. In addition to supporting insect populations, Butterfly Milkweed milkweeds also provide other landscape benefits due to their extensive root systems (sometimes deep roots, sometimes horizontal) that Photos by Dave Hanson decrease compaction, add organic material to the soil and improve unless otherwise stated water infiltration. Common milkweed is probably the best known milkweed species as it is found in all counties of the state and was included on some county prohibited noxious weed lists. The species was considered a common agricultural weed as its extensive root network made it difficult to remove from agricultural fields with cultivators. Now the species is effectively removed from genetically modified corn and soybean fields that are sprayed with herbicide. This practice has contributed to significant declines in milkweed species, with an estimated 58% decline in the Midwest between 1999 and 2010 and a corresponding 81% decline in monarch butterfly production (Pleasants & Oberhauser, 2013). -

"National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary."
Intro 1996 National List of Vascular Plant Species That Occur in Wetlands The Fish and Wildlife Service has prepared a National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary (1996 National List). The 1996 National List is a draft revision of the National List of Plant Species That Occur in Wetlands: 1988 National Summary (Reed 1988) (1988 National List). The 1996 National List is provided to encourage additional public review and comments on the draft regional wetland indicator assignments. The 1996 National List reflects a significant amount of new information that has become available since 1988 on the wetland affinity of vascular plants. This new information has resulted from the extensive use of the 1988 National List in the field by individuals involved in wetland and other resource inventories, wetland identification and delineation, and wetland research. Interim Regional Interagency Review Panel (Regional Panel) changes in indicator status as well as additions and deletions to the 1988 National List were documented in Regional supplements. The National List was originally developed as an appendix to the Classification of Wetlands and Deepwater Habitats of the United States (Cowardin et al.1979) to aid in the consistent application of this classification system for wetlands in the field.. The 1996 National List also was developed to aid in determining the presence of hydrophytic vegetation in the Clean Water Act Section 404 wetland regulatory program and in the implementation of the swampbuster provisions of the Food Security Act. While not required by law or regulation, the Fish and Wildlife Service is making the 1996 National List available for review and comment. -

Holmes [email protected] Department of Biology Baylor University Waco, Texas Introduction This document has been produced to serve as a quick guide to the identification of milkweeds (Asclepias spp.) in Texas. For the species listed in Table 1 below, basic information such as range (in this case county distribution), habitat, and key identification characteristics accompany a photograph of each species. This information comes from a variety of sources that includes the Manual of the Vascular Flora of Texas, Biota of North America Project, knowledge of the authors, and various other publications (cited in the text). All photographs are used with permission and are fully credited to the copyright holder and/or originator. Other items, but in particular scientific publications, traditionally do not require permissions, but only citations to the author(s) if used for scientific and/or nonprofit purposes. Names, both common and scientific, follow those in USDA NRCS (2015). When identifying milkweeds in the field, attention should be focused on the distinguishing characteristics listed for each species. -
Hybridization Between Asclepias Purpurascens and Asclepias Syriaca (Apocynaceae): a Cause for Concern?1
Journal of the Torrey Botanical Society 146(4): 278–290, 2019. Hybridization between Asclepias purpurascens and Asclepias syriaca (Apocynaceae): A cause for concern?1 Steven B. Broyles2,4 and Geordie Elkins3 2Biological Sciences Department, SUNY Cortland, Cortland, NY 13045 and 3Highstead, 127 Lonetown Road, Redding, CT 06896 Abstract. Rare plant species can be at risk of hybridization, reduced genetic variation, and genetic assimilation when a numerically abundant congener co-occurs in or invades their habitat. We investigated hybridization between a species in decline, Asclepias purpurascens L., and its common and widespread congener, Asclepias syriaca L. A total of 40 morphological traits were measured on 60 flowering plants from a mixed population in Connecticut. Cluster and principal component analyses identified two distinct clusters of parental species taxa and a third cluster representing putative hybrids. Although leaf traits of putative hybrids were more similar to A. syriaca, floral traits and the morphological space on the principal component analysis were more similar to A. purpurascens. This suggests that the population contains a mix of F1 and advanced generation hybrids with the possibility of introgression into A. purpurascens. Although putative hybrids are intermediate for most traits, pollen counts reveal reduced fertility of presumed hybrid that might influence mating behaviors and increase the likelihood of backcrossing with A. purpurascens. We suggest a combination of morphological traits that better identify the two parental species as well as hybrids in the field. Conservationists should consider options of managing A. syriaca where A. purpurascens needs protection from competition to prevent genetic assimilation of the latter. Key words: Asclepias, conservation, hybridization Angiosperms abound with natural and anthro- 2015). -

The Vascular Flora of Sandy Run Savannas State Natural Area, Onslow and Pender Counties, North Carolina --In Press-- John B
The Vascular Flora of Sandy Run Savannas State Natural Area, Onslow and Pender Counties, North Carolina --In Press-- John B. Taggart Department of Environmental Studies, University of North Carolina at Wilmington, 601 South College Road, Wilmington, North Carolina 28403 ______________________________________________________________________________ ABSTRACT The vascular plants of Sandy Run Savannas State Natural Area, located in portions of Onslow and Pender counties, North Carolina, are presented as an annotated species list. A total of 590 taxa in 315 genera and 119 families were collected from eight plant communities. Families with the highest numbers of species were the Asteraceae (80), Poaceae (66), and Cyperaceae (65). Two species, Carex lutea (golden sedge) and Thalictrum cooleyi (Cooley’s meadowrue), have federal endangered status. A total of 23 taxa are tracked by the North Carolina Natural Heritage Program, while 29 others are considered rare, but not included on the priority list. Of 44 species considered strict endemic or near-endemic taxa to the North and South Carolina Coastal Plain, 18 (41%) were collected in this study. Selected pine savannas within the site were rated as nationally significant by the North Carolina Natural Heritage Program. Fifty-one (51) non-native species were present and represented 8.7 % of the flora. _________________________________________________________________________ INTRODUCTION Sandy Run Savannas State Natural Area encompasses portions of western Onslow and northeastern Pender counties in North Carolina. State acquisition of this coastal plain site began in 2007 as a cooperative effort between The Nature Conservancy in North Carolina and the North Carolina Division of Parks and Recreation to protect approximately 1,214 ha comprised of seven tracts (Figure 1).
