  • 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

  • Martian Crater Morphology
    ANALYSIS OF THE DEPTH-DIAMETER RELATIONSHIP OF MARTIAN CRATERS A Capstone Experience Thesis Presented by Jared Howenstine Completion Date: May 2006 Approved By: Professor M. Darby Dyar, Astronomy Professor Christopher Condit, Geology Professor Judith Young, Astronomy Abstract Title: Analysis of the Depth-Diameter Relationship of Martian Craters Author: Jared Howenstine, Astronomy Approved By: Judith Young, Astronomy Approved By: M. Darby Dyar, Astronomy Approved By: Christopher Condit, Geology CE Type: Departmental Honors Project Using a gridded version of maritan topography with the computer program Gridview, this project studied the depth-diameter relationship of martian impact craters. The work encompasses 361 profiles of impacts with diameters larger than 15 kilometers and is a continuation of work that was started at the Lunar and Planetary Institute in Houston, Texas under the guidance of Dr. Walter S. Keifer. Using the most ‘pristine,’ or deepest craters in the data a depth-diameter relationship was determined: d = 0.610D 0.327 , where d is the depth of the crater and D is the diameter of the crater, both in kilometers. This relationship can then be used to estimate the theoretical depth of any impact radius, and therefore can be used to estimate the pristine shape of the crater. With a depth-diameter ratio for a particular crater, the measured depth can then be compared to this theoretical value and an estimate of the amount of material within the crater, or fill, can then be calculated. The data includes 140 named impact craters, 3 basins, and 218 other impacts. The named data encompasses all named impact structures of greater than 100 kilometers in diameter.

(Strelitziaceae), a native of South Africa, is newly recorded as a sparingly naturalised weed for New South Wales and represents new family, generic and species records for the state. Descriptions, notes and identification key are provided for the family, genus and species. Introduction Strelitzia nicolai Regel & Körn. (Giant White Bird of Paradise or Natal Wild Banana; Strelitziaceae), a native of South Africa, is a common horticultural subject in eastern Australia. Recently a small colony of plants was discovered at Minnie Water (c. 60 km NNE of Coffs Harbour, North Coast, New South Wales). The colony is of note as some plants were 8 m tall (suggesting they had been there for some time) and that they were setting viable seed. Seedlings were found within this population and Milne and Luxton have observed that the species is being found in increasing numbers on council land and in National Parks of the area.

Historical Setting of the Guianan Plant Heritage The Guianas are embedded high in the green shoulder of northern South America, an area once known as the "Wild Coast". They are the only non-Latin American countries in South America, and are situated just north of the Equator in a configuration with the Amazon River of Brazil to the south and the Orinoco River of Venezuela to the west. The three Guianas comprise, from west to east, the countries of Guyana (area: 83,000 square miles; capital: Georgetown), Surinam (area: 63, 037 square miles; capital: Paramaribo) and French Guiana (area: 34, 740 square miles; capital: Cayenne). Perhaps the earliest physical contact between Europeans and the present-day Guianas occurred in 1500 when the Spanish navigator Vincente Yanez Pinzon, after discovering the Amazon River, sailed northwest and entered the Oyapock River, which is now the eastern boundary of French Guiana.

  • The Bird of Paradise Produces Spectacular Garden Flowers With
    The Bird of Paradise produces spectacular garden flowers with brilliant orange and blue petals, and has large, bluish-green leathery leaves, not unlike those of bananas. In fact, until recently, Strelitzia was classified as a genus within the Musaceae, the Banana family, and was only recently placed in the Strelitziaceae. Strelitzia is a native of the Cape Province of South Africa where the flowers are visited by Sunbirds, but not pollinated by them. Sunbirds steal nectar without contributing to pollination. The nectary is covered by convoluted bases of petals which reduce nectar theft by sunbirds, but are probably more effective at deterring nectar theft by insects. However, another bird, the Weaver Bird, does pollinate Strelitzia, visiting the flowers, perching on the blue petal and contacting both anthers and stigma. Strelitzia reginae in its native habitat in South Africa grows on river banks and cleared areas of coastal scrub. The first Strelitzia plants were brought to Australia by sailing ships in the early days of European settlement so they have been popular with Australian gardeners seemingly forever. However, if you are tempted to plant one at home, make sure you plant it in a location from which you will never, ever need to move it. Strelitzia plants are like icebergs, only a small part is visible above the ground. You may well need a bobcat or even a bulldozer to remove an old, established plant. The three genera in the family Strelitziaceae have an interesting distribution. Strelitzia (5 species) occur in southern Africa, Ravenala madagascariensis, the Travellers’ Palm, comes from Madagascar and Phenakospermum guianense can be found in the Amazon basin of South America.

  • The Moon After Apollo
    ICARUS 25, 495-537 (1975) The Moon after Apollo PAROUK EL-BAZ National Air and Space Museum, Smithsonian Institution, Washington, D.G- 20560 Received September 17, 1974 The Apollo missions have gradually increased our knowledge of the Moon's chemistry, age, and mode of formation of its surface features and materials. Apollo 11 and 12 landings proved that mare materials are volcanic rocks that were derived from deep-seated basaltic melts about 3.7 and 3.2 billion years ago, respec- tively. Later missions provided additional information on lunar mare basalts as well as the older, anorthositic, highland rocks. Data on the chemical make-up of returned samples were extended to larger areas of the Moon by orbiting geo- chemical experiments. These have also mapped inhomogeneities in lunar surface chemistry, including radioactive anomalies on both the near and far sides. Lunar samples and photographs indicate that the moon is a well-preserved museum of ancient impact scars. The crust of the Moon, which was formed about 4.6 billion years ago, was subjected to intensive metamorphism by large impacts. Although bombardment continues to the present day, the rate and size of impact- ing bodies were much greater in the first 0.7 billion years of the Moon's history. The last of the large, circular, multiringed basins occurred about 3.9 billion years ago. These basins, many of which show positive gravity anomalies (mascons), were flooded by volcanic basalts during a period of at least 600 million years. In addition to filling the circular basins, more so on the near side than on the far side, the basalts also covered lowlands and circum-basin troughs.
