"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. -
The Vegetation and Flora of Auyuittuq National Park Reserve, Baffin Island

Box l 310 Ya\lowknif e, NT XlA 2L9 ii! ABSTRACT The purposes of this investigation were to describe the flora and major types of plant communities present in Auyuittuq National Park Reserve, Baffin Island, and to evaluate factors influencing the distribution of the local vegetation. Six major types of plant communities were recognized based on detailed descriptions of the physical environment, flora, and ground cover of shrubs, herbs, bryophytes, ·and lichens at 100 sites. Three highly interrelated variables (elevation, soil moisture, and texture of surficial deposits) seemed to be important in determining the distribution and abundance of plant communities. Continuous vegetation developed mainly at low elevations on mesic to wet, fine-textured deposits. Wet tundra, characterized by abundant cover of shrubs, grasses, sedges, and forbs, occurred most frequently on wet, fine-textured marine and fluvial sediments. Dwarf shrub-qram.inoid comm.unities were comprised of abundant shrubs, grasses, sedges and forbs and were found most frequently below elevations of 400 m on mesic till or colluvial deposits. Dwarf shrub comm.unities were characterized by abundant dwarf shrub and lichen cover. They developed at similar elevations and on similar types of surficial deposits as dwarf-shrub graminoid communities. -
Saxifragaceae Saxifrage Family
Saxifragaceae Page | 921 saxifrage family About 700 species in 40 genera comprise this family of herbs and shrubs. Nova Scotia has several representative species, ranging from the highland saxifrages to deciduous forest mitreworts. Calyx and corolla are 4-5-merous. Sepals appear to be lobes of the hypanthium. Petals are variable in size and dissection. Stamens are equal in number or double the number of sepals and petals. Pistils number one or three; carpels 2–5, united basally to form a compound ovary, which may be deeply lobed. Fruit is dehiscent. Leaves are alternate with or without stipules, basal or cauline. Several genera are cultivated, but not persisting outside of cultivation. Key to genera A. Leaves opposite, cauline; plant sprawling; flowers 4-merous; petals absent. Chrysosplenium aa. Leaves mostly in a basal rosette, or very small and alternate; plants erect; B flowers 5-merous; petals present. B. Flowers solitary; stamens equal in number to the petals. Parnassia bb. Flowers several to numerous; stamens double the number of petals. C C. Leaves small, crowded, sessile or nearly so. Saxifraga cc. Leaves mostly basal, on long petioles. D D. Leaves serrate; petals entire; capsule beak Tiarella acute. dd. Leaves crenate; petals finely cleft; capsule beak Mitella obtuse. Chrysosplenium L. Plants of cool regions, all 40 species have minute flowers. Petals are absent; calyx is four-merous. Flowers are perfect and perigynous. Hypanthium has eight lobes in its centre, with 4–8 stamens attached. Perennial creeping herbs, they are freely branched, their leaves simple. 3-81 Saxifragaceae Page | 922 Chrysosplenium americanum Schwein. Golden saxifrage; dorine d'Amérique A smooth, nearly succulent plant, it has many trailing branches, forming thick mats. -

Box 117800, University of Florida, Gainesville, Florida 32611-7800 USA Phylogenetic relationships and biogeography of the genus Cerastium were studied using sequences of three noncoding plastid DNA regions (trnL intron, trnL-trnF spacer, and psbA-trnH spacer). A total of 57 Cerastium taxa was analyzed using two species of the putative sister genus Stellaria as outgroups. Maximum parsimony analyses identi®ed four clades that largely corresponded to previously recognized infrageneric groups. The results suggest an Old World origin and at least two migration events into North America from the Old World. The ®rst event possibly took place across the Bering land bridge during the Miocene. Subsequent colonization of South America occurred after the North and South American continents joined during the Pliocene. A more recent migration event into North America probably across the northern Atlantic took place during the Quaternary, resulting in the current circumpolar distribution of the Arctic species. -

Morphological and genetic differentiation of Saxifraga hirculus L. (Saxifragaceae) populations in Lithuania. Acta Biol. Univ. Daugavp., Suppl. 2: 69 – 78. Summarized data of investigations of nine Saxifraga hirculus L. populations in Lithuania are presented. The abundance of populations is low, normally from one to fifteen floral shoots in a 0.25 m2 plot. Ecologic density and morphologic features of S. hirculus highly varies throughout different habitats in Lithuania. S. hirculus populations in Lithuania are characterized by medium plasticity of phenotypic features of generative individuals. The diversity of RAPD markers was studied in 76 plants of Saxifraga hirculus from five populations in Lithuania. Analysis of molecular variance (AMOVA) showed high level of differentiation among studied populations of S. hirculus. The interpopulation variance component accounted for 27%. The genetic distance between populations ranged from 0.168 to 0.258. We found no correlation between the genetic and geographic distances of the study S. hirculus populations. The level of average heterozygosity was highest in Galvydiske population (0.338) and the lowest in Juodle population (0.295).

Cyperaceae of Alberta
AN ILLUSTRATED KEY TO THE CYPERACEAE OF ALBERTA Compiled and writen by Linda Kershaw and Lorna Allen April 2019 © Linda J. Kershaw & Lorna Allen This key was compiled using information primarily from and the Flora North America Association (2008), Douglas et al. (1998), and Packer and Gould (2017). Taxonomy follows VASCAN (Brouillet, 2015). The main references are listed at the end of the key. Please try the key this summer and let us know if there are ways in which it can be improved. Over the winter, we hope to add illustrations for most of the entries. The 2015 S-ranks of rare species (S1; S1S2; S2; S2S3; SU, according to ACIMS, 2015) are noted in superscript ( S1; S2;SU) after the species names. For more details go to the ACIMS web site. Similarly, exotic species are followed by a superscript X, XX if noxious and XXX if prohibited noxious (X; XX; XXX) according to the Alberta Weed Control Act (2016).
