  • Osmanthus Fragrans
    Osmanthus fragrans (Sweet Osmanthus, fragrant Tea olive) Sweet Tea Olive is large evergreen shrub or small tree is capable of reaching 6-8 m in height and width but is most often seen at 3-4 m high with a 2 m spread. The shiny, medium-green leaves have paler undersides and are joined from October through March by a multitude of small, but extremely fragrant, white blossoms. They perfume a large area of the landscape and can be showy in some years. The plant has a upright oval to columnar growth habit in youth. Sweet Osmanthus is ideal for use as an unclipped hedge or trained as a small tree, and should be placed where its fragrance can be enjoyed. Since the flowers are not particularly showy, people will wonder where the delightful fragrance is coming from. Sweet Osmanthus should be grown in full sun or partial shade in well-drained soil. Plants are fairly drought-tolerant once established but will perform their best with ample moisture. Needs acidic soil to grow in.

  • Torus-Bearing Pit Membranes in Species of Osmanthus
    IAWA Journal, Vol. 31 (2), 2010: 217–226 TORUS-BEARING PIT MEMBRANES IN SPECIES OF OSMANTHUS Roland Dute1, 5, David Rabaey2, John Allison1 and Steven Jansen3, 4 SUMMARY Torus thickenings of pit membranes are found not only in gymnosperms, but also in certain genera of dicotyledons. One such genus is Osmanthus. Wood from 17 species of Osmanthus was searched for tori. Fourteen spe- cies from three of the four sections investigated possessed these thick- enings. Ten of the species represent new records. Only the three New Caledonian species of Section Notosmanthus lacked tori. This observation in combination with other factors serves to isolate this section from the remainder of the genus. Key words: Notelaea, Osmanthus, pit membrane, torus. INTRODUCTION Osmanthus is a member of the Oleaceae (Olive Family), a moderate-sized family with circa 24 genera and 615 spp. (Stevens 2001). There are 33 natural species within the genus (Table 1; Xiang et al. 2008), and they show a tropical to temperate distribution (Bailey & Bailey 1976; Denk et al. 2001; Xiang et al. 2008). Generally, individual shrubs are found in moist forests (Hsieh et al. 1998; Chou et al. 2000; Denk et al. 2001), frequently on steep slopes (Green 1958). In some instances populations are sub- ject to monsoon conditions and hence to periods of relatively low rainfall (Yang et al. 2008; Hua 2008). Tori are thickenings of intervascular pit membranes found not only in gymnosperm, but also in angiosperm wood, including that of Osmanthus (Dute et al. 2008; Dute et al. 2010). Tori were first observed in O. fragrans, O.

  • Abies Concolor (White Fir)
    Compiled here is distribution, characteristics and other information on host species featured as ‘Host of the Month’ in past issues of the COMTF Monthly Report. Abies concolor (white fir) This is an evergreen tree native to the mountains of southern Oregon, California, the southern Rocky Mountains, and Baja California. Large and symmetrical, white fir grows 80 – 120ft tall and 15 – 20ft wide in its native range and in the Pacific Northwest. White fir is one of the top timber species found in the Sierra Nevada Mountains of CA and is a popular Christmas tree, as well as one of the most commonly grown native firs in Western gardens. Young trees are conical in shape, but develop a dome-like crown with age. The flattened needles of white fir are silvery blue-green, blunt at the tip , and grow 2 – 3in long. Often curving upwards, the needles extend at right angles from the twig, and twigs produce a citrus smell when needles are broken. White fir is monoecious, producing yellow- to red-toned, catkin-like male flowers and inconspicuous yellow-brown female flowers. The oblong cones grow 3 – 5 in upright, are yellow-green to purple in color, and are deciduous at maturity, dispersing seed in the fall. New twigs are dark- orange, but become gray-green, then gray with maturity. The bark of saplings is thin, smooth, and gray, turning thick, ash-gray with age, and developing deep irregular furrows. P. ramorum- infected Abies concolor (white fir) was first reported in the October 2005 COMTF newsletter as having been found at a Christmas tree farm in the quarantined county of Santa Clara.

  • Introduction
    INTRODUCTION Although much of the San Francisco Bay Region is densely populated and industrialized, many thousands of acres within its confines have been set aside as parks and preserves. Most of these tracts were not rescued until after they had been altered. The construction of roads, the modification of drainage patterns, grazing by livestock, and the introduction of aggressive species are just a few of the factors that have initiated irreversible changes in the region’s plant and animal life. Yet on the slopes of Mount Diablo and Mount Tamal- pais, in the redwood groves at Muir Woods, and in some of the regional parks one can find habitats that probably resemble those that were present two hundred years ago. Even tracts that are far from pristine have much that will bring pleasure to those who enjoy the study of nature. Visitors to our region soon discover that the area is diverse in topography, geology, cli- mate, and vegetation. Hills, valleys, wetlands, and the seacoast are just some of the situa- tions that will have one or more well-defined assemblages of plants. In this manual, the San Francisco Bay Region is defined as those counties that touch San Francisco Bay. Reading a map clockwise from Marin County, they are Marin, Sonoma, Napa, Solano, Contra Costa, Alameda, Santa Clara, San Mateo, and San Francisco. This book will also be useful in bordering counties, such as Mendocino, Lake, Santa Cruz, Monterey, and San Benito, because many of the plants dealt with occur farther north, east, and south. For example, this book includes about three-quarters of the plants found in Monterey County and about half of the Mendocino flora.

  • A University Thesis Presented to the Faculty
    ISOLATION AND CHARACTERIZATION OF VIRUS-LIKE PARTICLES FROM LILIACEAE __________________ A University Thesis Presented to the Faculty of California State University, East Bay __________________ In Partial Fulfillment of the Requirements for the Degree Master of Science in Biology __________________ By Anna-Louise Doss December, 2013 ! ! "! ! Abstract Transposable elements are mobile genetic elements that have the ability to replicate and relocate to different positions in the genome of a cell. These elements are ubiquitous in the genomes of all eukaryotic organisms and are credited with being the source of the vast variation in genome size among related organisms, such as angiosperms, which can differ in genome size by as much as 1000-fold. Retroelements in particular are very predominant in angiosperms and have been shown to account for anywhere from 30% to 90% of the genome. The massive genomes that are common in the Liliaceae family (mean C value of 50 pg) are extreme examples of retroelement proliferation. The Family Liliaceae provides a good model system for studying the mechanisms utilized by transposable elements to proliferate and evade host defenses, and for studying the impact transposable elements have on the evolution of genomes. However, due to their large genome size and the vast prevalence of repetitive DNA, members of the Liliaceae have not yet been fully sequenced nor have their transposable elements been fully characterized. In addition, there has been no attempt to isolate and characterize active retroelements from Liliaceae species in the form of virus-like particles. This thesis research will utilize and modify existing virus-like particle isolation techniques for retroelement isolation and characterization using barley as a model plant.

  • Classification of the Vegetation Alliances and Associations of Sonoma County, California
    Classification of the Vegetation Alliances and Associations of Sonoma County, California Volume 1 of 2 – Introduction, Methods, and Results Prepared by: California Department of Fish and Wildlife Vegetation Classification and Mapping Program California Native Plant Society Vegetation Program For: The Sonoma County Agricultural Preservation and Open Space District The Sonoma County Water Agency Authors: Anne Klein, Todd Keeler-Wolf, and Julie Evens December 2015 ABSTRACT This report describes 118 alliances and 212 associations that are found in Sonoma County, California, comprising the most comprehensive local vegetation classification to date. The vegetation types were defined using a standardized classification approach consistent with the Survey of California Vegetation (SCV) and the United States National Vegetation Classification (USNVC) system. This floristic classification is the basis for an integrated, countywide vegetation map that the Sonoma County Vegetation Mapping and Lidar Program expects to complete in 2017. Ecologists with the California Department of Fish and Wildlife and the California Native Plant Society analyzed species data from 1149 field surveys collected in Sonoma County between 2001 and 2014. The data include 851 surveys collected in 2013 and 2014 through funding provided specifically for this classification effort. An additional 283 surveys that were conducted in adjacent counties are included in the analysis to provide a broader, regional understanding. A total of 34 tree-overstory, 28 shrubland, and 56 herbaceous alliances are described, with 69 tree-overstory, 51 shrubland, and 92 herbaceous associations. This report is divided into two volumes. Volume 1 (this volume) is composed of the project introduction, methods, and results. It includes a floristic key to all vegetation types, a table showing the full local classification nested within the USNVC hierarchy, and a crosswalk showing the relationship between this and other classification systems.
