  • Plant Guide for Fourwing Saltbush (Atriplex Canescens)
    Plant Guide saline-sodic soils (Ogle and St. John, 2008). It has FOURWING SALTBUSH excellent drought tolerance and has been planted in highway medians and on road shoulders, slopes, and other Atriplex canescens (Pursh) Nutt. disturbed areas near roadways. Because it is a good Plant Symbol = ATCA2 wildlife browse species, caution is recommended in using fourwing saltbush in plantings along roadways. Its Contributed by: USDA NRCS Idaho Plant Materials extensive root system provides excellent erosion control. Program Reclamation: fourwing saltbush is used extensively for reclamation of disturbed sites (mine lands, drill pads, exploration holes, etc,). It provides excellent species diversity for mine land reclamation projects. Status Please consult the PLANTS Web site and your State Department of Natural Resources for this plant’s current status (e.g., threatened or endangered species, state noxious status, and wetland indicator values). Description Fourwing saltbush is a polymorphic species varying from deciduous to evergreen, depending on climate. Its much- branched stems are stout with whitish bark. Mature plants range from 0.3 to 2.4 m (1 to 8 ft) in height, depending on ecotype and the soil and climate. Its leaves are simple, alternate, entire, linear-spatulate to narrowly oblong, Fourwing saltbush. Photo by Steven Perkins @ USDA-NRCS canescent (covered with fine whitish hairs) and ½ to 2 PLANTS Database inches long. Its root system is branched and commonly very deep reaching depths of up to 6 m (20 ft) when soil Alternate Names depth allows (Kearney et al., 1960). Common Alternate Names: Fourwing saltbush is mostly dioecious, with male and Chamise, chamize, chamiso, white greasewood, saltsage, female flowers on separate plants (Welsh et al., 2003); fourwing shadscale, bushy atriplex however, some monoecious plants may be found within a population.

  • 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

We have never had so many problems in fitting the range of plants we have “on our books” into the available space! We always try and keep our lists “democratic” and balanced although at times our prejudices show and one or two groups rise to the top. This year we are offering an unprecedented range of calochortus in a multiplicity of sizes, colours and flower shapes from the charming fairy lanterns of C. albidus through to the spectacular, later-flowering mariposas with upward-facing bowl-shaped flowers in a rich tapestry of shades from canary-yellow through to lilac, lavender and purple. Counterpoised to these flashy dandies we are offering an assortment of choice muscari whose quiet charm, softer colours and Tulipa vvedenskyi Tecophilaea cyanocrocus Violacea persistent flowering make them no less effective in the winter and spring garden. Standouts among this group are the deliciously scented duo, M. muscarimi and M. macrocarpum and the striking and little known tassel-hyacith, M. weissii. While it has its devotees, many gardeners are unaware of the qualities of the large and diverse tribe of “onions”, known as alliums.

The national park was F E R N S established in 1968. In 1994, a cooperative agreement with the California Department of Parks and Recreation added Del Norte Coast, Prairie Creek, Athyriaceae – Lady Fern Family and Jedediah Smith Redwoods state parks to form a single administrative Athyrium filix-femina var. cyclosporum • northwestern lady fern unit. Together they comprise about 133,000 acres (540 km2), including 37 miles of coast line.

  • Abronia Maritima Nutt. Ex S. Wats
    SPECIES Abronia maritima Nutt. ex S. Wats. Family: Nyctaginaceae; NRCS CODE: Gary A. Monroe @ USDA-NRCS PLANTS Database ABMA2 Order: Caryophyllales; Subclass: Caryophyllidae; Class: Magnoliopsida Subspecific taxa None. Synonyms None listed. Common name red sand verbena (CalFlora, USDA PLANTS), sticky sand verbena (CalFlora) Taxonomic relationships Abronia latifolia Eschsch. and A. umbellata Lam. are closely related species (Blancas 2001). Related taxa in region May co-occur with A. latifolia and A. umbellata where distributions overlap. All three occur between Point Arguello, Santa Barbara Co., to Morro Bay in San Luis Obispo Co. (Tilllett 1967). Other CNPS list 4.2, limited distribution. Endemic to California and Baja California. There has been concern that hybridization with the two more widespread, co-occurring species of Abronia together with rapid loss of its coastal dune habitat are making the plants vulnerable to extinction (Blancas 2001). Genetic and morphological studies by Blancas (2001) were consistent with there being a high rate of hybridization with A. umbellata within a few small populations. GENERAL Map Data provided by the participants of the Consortium of California Herbaria represent 114 records with coordinate data out of 324 total records retrieved; data accessed 9/23/10. See Berkeley Mapper: http://ucjeps.berkeley.edu/consortium Geographic range Sparsely located in central and southern California and Baja California (Hickman 1993).
