  • Washington Flora Checklist a Checklist of the Vascular Plants of Washington State Hosted by the University of Washington Herbarium
    Washington Flora Checklist A checklist of the Vascular Plants of Washington State Hosted by the University of Washington Herbarium The Washington Flora Checklist aims to be a complete list of the native and naturalized vascular plants of Washington State, with current classifications, nomenclature and synonymy. The checklist currently contains 3,929 terminal taxa (species, subspecies, and varieties). Taxa included in the checklist: * Native taxa whether extant, extirpated, or extinct. * Exotic taxa that are naturalized, escaped from cultivation, or persisting wild. * Waifs (e.g., ballast plants, escaped crop plants) and other scarcely collected exotics. * Interspecific hybrids that are frequent or self-maintaining. * Some unnamed taxa in the process of being described. Family classifications follow APG IV for angiosperms, PPG I (J. Syst. Evol. 54:563?603. 2016.) for pteridophytes, and Christenhusz et al. (Phytotaxa 19:55?70. 2011.) for gymnosperms, with a few exceptions. Nomenclature and synonymy at the rank of genus and below follows the 2nd Edition of the Flora of the Pacific Northwest except where superceded by new information. Accepted names are indicated with blue font; synonyms with black font. Native species and infraspecies are marked with boldface font. Please note: This is a working checklist, continuously updated. Use it at your discretion. Created from the Washington Flora Checklist Database on September 17th, 2018 at 9:47pm PST. Available online at http://biology.burke.washington.edu/waflora/checklist.php Comments and questions should be addressed to the checklist administrators: David Giblin ([email protected]) Peter Zika ([email protected]) Suggested citation: Weinmann, F., P.F.

  • Checklist of Montana Vascular Plants
    Checklist of Montana Vascular Plants June 1, 2011 By Scott Mincemoyer Montana Natural Heritage Program Helena, MT This checklist of Montana vascular plants is organized by Division, Class and Family. Species are listed alphabetically within this hierarchy. Synonyms, if any, are listed below each species and are slightly indented from the main species list. The list is generally composed of species which have been documented in the state and are vouchered by a specimen collection deposited at a recognized herbaria. Additionally, some species are included on the list based on their presence in the state being reported in published and unpublished botanical literature or through data submitted to MTNHP. The checklist is made possible by the contributions of numerous botanists, natural resource professionals and plant enthusiasts throughout Montana’s history. Recent work by Peter Lesica on a revised Flora of Montana (Lesica 2011) has been invaluable for compiling this checklist as has Lavin and Seibert’s “Grasses of Montana” (2011). Additionally, published volumes of the Flora of North America (FNA 1993+) have also proved very beneficial during this process. The taxonomy and nomenclature used in this checklist relies heavily on these previously mentioned resources, but does not strictly follow anyone of them. The Checklist of Montana Vascular Plants can be viewed or downloaded from the Montana Natural Heritage Program’s website at: http://mtnhp.org/plants/default.asp This publication will be updated periodically with more frequent revisions anticipated initially due to the need for further review of the taxonomy and nomenclature of particular taxonomic groups (e.g. Arabis s.l ., Crataegus , Physaria ) and the need to clarify the presence or absence in the state of some species.

E-mail: [email protected] Received 23 September 2013; Revised 24 January 2014; Accepted 29 January 2014 Downloaded from Abstract Facultative crassulacean acid metabolism (CAM) describes the optional use of CAM photosynthesis, typically under http://jxb.oxfordjournals.org/ conditions of drought stress, in plants that otherwise employ C3 or C4 photosynthesis. In its cleanest form, the upregu- lation of CAM is fully reversible upon removal of stress. Reversibility distinguishes facultative CAM from ontogeneti- cally programmed unidirectional C3-to-CAM shifts inherent in constitutive CAM plants. Using mainly measurements of 24 h CO2 exchange, defining features of facultative CAM are highlighted in five terrestrial species, Clusia pratensis, Calandrinia polyandra, Mesembryanthemum crystallinum, Portulaca oleracea and Talinum triangulare. For these, we provide detailed chronologies of the shifts between photosynthetic modes and comment on their usefulness as experimental systems. Photosynthetic flexibility is also reviewed in an aquatic CAM plant, Isoetes howellii. Through by guest on March 19, 2014 comparisons of C3 and CAM states in facultative CAM species, many fundamental biochemical principles of the CAM pathway have been uncovered. Facultative CAM species will be of even greater relevance now that new sequencing technologies facilitate the mapping of genomes and tracking of the expression patterns of multiple genes.

  • Low Atmospheric CO2 Induces Nocturnal Carbon Accumulation in the Lycophyte 2 Genus Isoëtes 3 4 Authors: Jacob S

Certain 12 desert plant species, for example, avoid water loss by temporally segregating the light and 13 dark reactions of photosynthesis. By only opening their stomata at night these plants 14 inhibit significant water loss during the day. At night CO2 is incorporate into 4-carbon 15 acids for subsequent daytime fixation1-5. This behavior is known as Crassulacean Acid 16 Metabolism (CAM) and leads to noticeable diel cycles in pH of photosynthetic organs1-5. 17 Oddly, similar acidity cycles are found in the submerged aquatic lycophyte genus Isoëtes2,6- 18 12, which are not water limited in any sense. It has long been assumed that their nocturnal 19 CO2 accumulation is an adaptation to low daytime carbon levels in aquatic ecosystems, but 20 this has never been empirically tested2,6-13. Here, we offer direct evidence that CO2 21 starvation induces CAM-like nocturnal carbon accumulation in terrestrial Isoëtes.
