E-mail: [email protected] Abstract Evarts-Bunders P., Evarte-Bundere G., Medne M., Bojāre A., Krasnopoļska D., Svilāne I., 2020: The genus Corispermum L. (Amaranthaceae) in the Baltic States. – Botanica, 26(1): 61–75. The paper presents the data on taxonomical diversity and distribution patterns and dynamics of the Corisper- mum species in the Baltic States over the last hundred years. Field studies and the herbarium material analyses were carried out. The distribution dynamics was analysed by comparing all known localities of the Corisper- mum species in two time periods: by 1990, and from 1991 to the present. Analysis of the herbarium material confirmed that currently there are four species in the Baltic States:Corispermum hyssopifolium, C. declinatum, C. intermedium and C. pallasii. The only endemic species to the Eastern Baltic Region, C. intermedium, is con- sidered as typical for annual vegetation on embryonic shifting dunes and other coastal habitats. In Lithuania, this species is considered extinct or almost extinct, as has not been found for more than 30 years, only its hy- brids with C. pallasii. The largest and most stable population of C. intermedium has been found on the eastern shore of the Gulf of Rīga in Latvia. Other species such as ephemerophytic C. hyssopifolium and C. declinatum also prefer dry and disturbed habitats. Both have become less frequent in recent years. However, potentially invasive C. pallasii has been observed in the region with increasing distribution dynamics. The Estonian and Latvian herbaria analysis confirmed that all specimens previously identified asC. algidum after re-examination were identified asC. pallasii or C. intermedium and more often as hybrid C. intermedium × C. pallasii. Keywords: alien species, Baltic States, chorology, coastal habitats, Corispermum, distribution dynamics. INTRODUCTION characters and presence or absence of perianth seg- ments.

  • 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.

  • Corispermum ) in Canada
    An Analysis of the Distribution, Ecology, and Status of Bugseeds (Corispermum ) in Canada DIANA BIZECKI ROBSON The Manitoba Museum, 190 Rupert Avenue, Winnipeg, Manitoba R3B 0N2 Canada; e-mail: [email protected] Robson, Diana Bizecki. 2010. An analysis of the distribution, ecology, and status of bugseeds ( Corispermum ) in Canada. Canadian Field-Naturalist 124(3): 246 –255. The bugseeds ( Corispermum spp.) are a genus of annual plants that are uncommon due to their psammophilic, ruderal habit. Bugseeds are typically found in natural areas with some bare sand, like sand dunes, but are also present in anthropogenically impacted sandy or gravelly areas. Increasing dune stabilization may be causing the endangerment of some Bugseed species. Assessing the rarity of the five species in Canada is hindered by the lack of recently collected specimens and the use of out-dated nomenclature in herbaria. Specimens of bugseeds from major herbaria all across Canada were examined and re-identified using the most recent taxonomic treatment in the Flora of North America. Hairy Bugseed ( C. villosum ) was the most commonly collected taxon and Hooker’s Bugseed ( C. hookeri var. pseudodeclinatum ) the rarest. The natural distribution of all taxa, except Alaskan Bugseed ( C. ochotense ) which is only found in the far north, is from British Columbia to Ontario. Hairy, Hooker’s and American Bugseed ( C. americanum ) are also found in Quebec, where they may have been introduced from further west. Summaries of Bugseed localities and habitats, and distribution maps are presented to facilitate the status assessment of plants in this genus. Key Words: bugseeds, Corispermum , distribution, habitat, psammophile, status, Canada.

Native bugseed species Corispermum intermedium Schweigg and alien Corispermum pallasii Steven in coastal habitats of Latvia - new knowledges of distribution and invasions. Acta Biol. Univ. Daugavp., 16 (2): 165 – 174. Corispermum is known as one of taxonomically most problematic genus in Chenopodiaceae and species identification is primarily based on fruit characters and presence or absence of perigonium. Six species were reported for the territory of Baltic countries and Latvia. The endemic species for Eastern Baltic region – C. intermedium Schweigg. is considered as typical for annual vegetation on embryonic shifting dunes and other coastal habitats, another species in similar habitats is the neophytic and invasive C. pallasii Steven. At the same time, the endemic C. intermedium is not officially protected in Latvia in spite of fact, that the population of our only native bugseed species is decreasing and the areal has been narrowing for several years due to natural reasons and as the result of human activities. It is completely clear, that remaining populations of C. intermedium in Latvia should be protected before the species becomes extinct as it happened in Poland and Russia. Key words: Corispermum, Latvia, endemic species, invasive species, coastal habitats, chorology. Pēteris Evarts-Bunders, Gunta Evarte-Bundere, Aiva Bojāre, Dana Krasnopoļska.
