New orchid species are rarely discovered on a province-wide scale today, particularly in an area as well-explored and urbanized as the island of Montreal. Endangered in Canada, this species is not only a classic symbol of the challenges of conservation and preservation of natural environments, but also a reminder of the great biological richness in the Montreal area. Le liparis à feuilles de lis (Liparis liliifolia) est une addition récente à la flore indigène du Québec (2007). La découverte de nouvelles espèces d’orchidées à l’échelle provinciale est un événement rarissime de nos jours, particulièrement sur un territoire aussi urbanisé et exploré que celui de l’île de Montréal ! Menacée au Canada, cette espèce est non seulement un symbole classique des enjeux de conservation et de préservation des milieux naturels, mais aussi un rappel de la grande richesse biologique montréalaise.

  • Outline of Angiosperm Phylogeny
    Outline of angiosperm phylogeny: orders, families, and representative genera with emphasis on Oregon native plants Priscilla Spears December 2013 The following listing gives an introduction to the phylogenetic classification of the flowering plants that has emerged in recent decades, and which is based on nucleic acid sequences as well as morphological and developmental data. This listing emphasizes temperate families of the Northern Hemisphere and is meant as an overview with examples of Oregon native plants. It includes many exotic genera that are grown in Oregon as ornamentals plus other plants of interest worldwide. The genera that are Oregon natives are printed in a blue font. Genera that are exotics are shown in black, however genera in blue may also contain non-native species. Names separated by a slash are alternatives or else the nomenclature is in flux. When several genera have the same common name, the names are separated by commas. The order of the family names is from the linear listing of families in the APG III report. For further information, see the references on the last page. Basal Angiosperms (ANITA grade) Amborellales Amborellaceae, sole family, the earliest branch of flowering plants, a shrub native to New Caledonia – Amborella Nymphaeales Hydatellaceae – aquatics from Australasia, previously classified as a grass Cabombaceae (water shield – Brasenia, fanwort – Cabomba) Nymphaeaceae (water lilies – Nymphaea; pond lilies – Nuphar) Austrobaileyales Schisandraceae (wild sarsaparilla, star vine – Schisandra; Japanese

  • Survey and Analysis of Plant Community Types of Writing-On-Stone Provincial Park
    Survey and Analysis of Plant Community Types of Writing-on-Stone Provincial Park Survey and Analysis of Plant Community Types of Writing-on-Stone Provincial Park FINAL REPORT Prepared for Alberta Sustainable Resource Development Resource Data Branch Edmonton, Alberta Prepared by Wildlands Ecological Consulting Ltd. #60 Neal Close, Red Deer, AB T4P 1N4 Office: (403) 346-1057 Fax: (403) 346-3257 March 29, 2004 ABSTRACT Identification and monitoring of biological diversity in Alberta is the primary mandate of Alberta Natural Heritage Information Centre (ANHIC). A fundamental strategy in the preservation of functional ecosystems is to identify and preserve a full compliment of habitat types, which in return support a diversity of animals, plants, and other life forms. Vegetation is an integral component of habitat and provides a relatively easy means of inventory and monitoring of ecosystem health both spatially and temporally. The current study, in Writing-on-Stone Provincial Park, focuses on the identification of unique riparian and coulee plant associations, or plant community type. The study area is situated approximately 8 km north of the USA border and 40 km east of the town of Milk River and occurs at the interface between the Mixedgrass and Dry Mixedgrass Natural Subregions. Priority research is currently required to address gaps in the identification, description and distribution of plant associations within the coulee and riparian zones of these Subregions. Many of these communities recur over the landscape but may occur as very small patches of 1m2 or less. Alberta Sustainable Resource Development (ASRD) Resource Data Division contracted Wildlands Ecological to complete an inventory of natural/semi-natural plant communities, statistically analyse the data, and describe potential plant community or association types.

Horticulture Research (2020) 7:197 Horticulture Research https://doi.org/10.1038/s41438-020-00422-w www.nature.com/hortres ARTICLE Open Access A chromosome-scale reference genome of Lobularia maritima, an ornamental plant with high stress tolerance Li Huang1,YazhenMa1, Jiebei Jiang1,TingLi1, Wenjie Yang1,LeiZhang1,LeiWu1,LandiFeng1, Zhenxiang Xi1, Xiaoting Xu1, Jianquan Liu 1,2 and Quanjun Hu 1 Abstract Lobularia maritima (L.) Desv. is an ornamental plant cultivated across the world. It belongs to the family Brassicaceae and can tolerate dry, poor and contaminated habitats. Here, we present a chromosome-scale, high-quality genome assembly of L. maritima based on integrated approaches combining Illumina short reads and Hi–C chromosome conformation data. The genome was assembled into 12 pseudochromosomes with a 197.70 Mb length, and it includes 25,813 protein-coding genes. Approximately 41.94% of the genome consists of repetitive sequences, with abundant long terminal repeat transposable elements. Comparative genomic analysis confirmed that L. maritima underwent a species-specific whole-genome duplication (WGD) event ~22.99 million years ago. We identified ~1900 species-specific genes, 25 expanded gene families, and 50 positively selected genes in L. maritima. Functional annotations of these genes indicated that they are mainly related to stress tolerance. These results provide new insights into the stress tolerance of L. maritima, and this genomic resource will be valuable for further genetic improvement of this important ornamental plant. 1234567890():,; 1234567890():,; 1234567890():,; 1234567890():,; Introduction ancestral species, WGDs can also promote reproductive Whole-genome duplication (WGD), or polyploidy, has isolation and thus facilitate speciation13.
