Geographic Range: 4. Habitat Invaded: 5. Historical Status and Rate of Spread in Wisconsin: 6. Proportion of potential range occupied: II. Invasive in Similar Climate YES NO X Zones United States: In 14 coastal California Counties and in Curry County, Oregon. In nursery in Washington. Canada: Nursery in British Columbia. Europe: Germany, the Netherlands, the United Kingdom, Poland, Spain, France, Belgium, and Sweden. III. Invasive in Similar Habitat YES X NO Types IV. Habitat Affected 1. Habitat affected: this disease thrives in cool, wet climates including areas in coastal California within the fog belt or in low- lying forested areas along stream beds and other bodies of water. Oaks associated with understory species that are susceptible to foliar infections are at higher risk of becoming infected. 2. Host plants: Forty-five hosts are regulated for this disease. These hosts have been found naturally infected by P. ramorum and have had Koch’s postulates completed, reviewed and accepted. Approximately fifty-nine species are associated with Phytophthora ramorum. These species are found naturally infected; P. ramorum has been cultured or detected with PCR but Koch’s postulates have not been completed or documented and reviewed. Northern red oak (Quercus rubra) is considered an associated host. See end of document for complete list of plant hosts. National Risk Model and Map shows susceptible forest types in the mid-Atlantic region of the United States. -
Witch-Hazel - Wikipedia, the Free Encyclopedia
Witch-hazel - Wikipedia, the free encyclopedia http://en.wikipedia.org/wiki/Witch-hazel You can support Wikipedia by making a tax-deductible donation. Witch-hazel From Wikipedia, the free encyclopedia Witch-hazel (Hamamelis) is a genus of flowering plants in the Witch-hazel family Hamamelidaceae, with two species in North America (H. virginiana and H. vernalis), and one each in Japan (H. japonica) and China (H. mollis). They are deciduous shrubs or (rarely) small trees growing to 3-8 m tall, rarely to 12 m tall. The leaves are alternately arranged, oval, 4-16 cm long and 3-11 cm broad, with a smooth or wavy margin. The horticultural name means "together with fruit"; its fruit, flowers, and next year's leaf buds all appear on the branch simultaneously, a rarity among trees. [1] The flowers are sometimes produced on the leafless stems in winter, thus one alternative name for the plant, "Winterbloom". [1] Each flower has four slender strap-shaped petals 1-2 cm long, pale to dark yellow, orange, or red. The fruit is a two-part capsule 1 cm long, containing a single 5 mm glossy black seed in each of the two parts; the capsule splits explosively at maturity in the autumn about 8 months after flowering, ejecting the seeds with sufficient force to fly for distances of up to 10 m, thus another Hamamelis virginiana alternative name "Snapping Hazel". [1] Scientific classification Kingdom: Plantae Hamamelis species are used as food plants by the larvae of Division: Magnoliophyta some Lepidoptera species including Feathered Thorn. Class: Magnoliopsida The name Witch has its origins in Middle English wiche, from Order: Saxifragales the Old English wice, meaning "pliant" or "bendable". -

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. -
Open As a Single Document
The Witch Hazel Family (Hamamelidaceae) by RICHARD E. WEAVER, JR. The Arnold Arboretum has claimed that there is a tree or shrub in bloom every month of the year on its grounds in Jamaica Plain, Mass. In many years this assertion is true, but only because of a single genus of plants, Hamamelis, the Witch Hazels. As December ar- rives, the last pale yellow flowers begin to fade on the Common Witch Hazel, H. virginiana, a native of the eastern United States. And with the New Year come the fragrant, bronzy flowers of the Vernal Witch Hazel, H. vernalis, closely followed by the bright and beautiful yellow blossoms of the Chinese species, H. mollis. The Witch Hazels belong to the Hamamelidaceae, a family of plants which are mostly neglected by the American horticultural public. Admittedly, the family is insignificant horticulturally com- pared with some others, for example, the Rose Family, as a result of the diversity and sheer number of its genera and species, and the Magnolia Family, because of the universal appeal of some of its members. But a high percentage of the species in the Hamamelida- ceae are first class ornamentals, possessing charm, beautiful and often fragrant flowers, unusual blooming times, and brilliant au- tumnal coloration. Most also are easy to grow if the soil is light and loamy, and they bloom reasonably well in partial shade. In addition, they are not bothered by any serious diseases or insect pests. This article will present a brief discussion of all of the genera which are hardy in the northern half of the United States. -
Duplication and Diversification in the APETALA1/FRUITFULL Floral
Copyright 2003 by the Genetics Society of America Duplication and Diversification in the APETALA1/FRUITFULL Floral Homeotic Gene Lineage: Implications for the Evolution of Floral Development Amy Litt1 and Vivian F. Irish Molecular, Cellular, and Developmental Biology, Yale University, New Haven, Connecticut 06520-4108 Manuscript received March 21, 2003 Accepted for publication June 11, 2003 ABSTRACT Phylogenetic analyses of angiosperm MADS-box genes suggest that this gene family has undergone multiple duplication events followed by sequence divergence. To determine when such events have taken place and to understand the relationships of particular MADS-box gene lineages, we have identified APETALA1/FRUITFULL-like MADS-box genes from a variety of angiosperm species. Our phylogenetic analyses show two gene clades within the core eudicots, euAP1 (including Arabidopsis APETALA1 and Antirrhinum SQUAMOSA) and euFUL (including Arabidopsis FRUITFULL). Non-core eudicot species have only sequences similar to euFUL genes (FUL-like). The predicted protein products of euFUL and FUL- like genes share a conserved C-terminal motif. In contrast, predicted products of members of the euAP1 gene clade contain a different C terminus that includes an acidic transcription activation domain and a farnesylation signal. Sequence analyses indicate that the euAP1 amino acid motifs may have arisen via a translational frameshift from the euFUL/FUL-like motif. The euAP1 gene clade includes key regulators of floral development that have been implicated in the specification of perianth identity. However, the presence of euAP1 genes only in core eudicots suggests that there may have been changes in mechanisms of floral development that are correlated with the fixation of floral structure seen in this clade. -

The Development of Hamamelis Intermedia©
The Development of Hamamelis ✕intermedia 341 The Development of Hamamelis ✕intermedia © Chris Lane Coblands Nurseries Ltd., Kent, United Kingdom Hamamelis ✕intermedia is a hybrid that has occurred spontaneously in cultivation, to date all named cultivars have occurred this way. This article aims to document the introduction and development of this hybrid from its early beginnings to the present day. INTRODUCTION The genus consists of four species: two species, Hamamalis virginiana (from which witch hazel extract is derived, for soothing cuts and grazes and used in eyewashes) and H. vernalis, the Ozark witch hazel, are from North America; two species are from Asia, H. japonica from Japan and H. mollis from China. Hamamelis ✕intermedia is a hybrid group between H. mollis and H. japonica which has occurred spontaneously in cultivation, the two species being widely separated in their natural distribution. It occurred initially at three sites, the Arnold Arboretum, U.S.A.; the Kalmthout Arboretum, Belgium; and Charlottenlund Botanic Garden, Denmark. Since that time the hybrid has been raised at various places, mainly in Europe but also in Japan. In recent times many of the hybrids are not primary (from the two species) but are the progeny of H. ✕intermedia cultivars. Several of these are much closer in appearance to the original parents and may be mistaken for forms of H. mollis or H. japonica. The remainder of this article chronicles the introductions to the present day. ARNOLD ARBORETUM Arnold Arboretum is where the first recorded hybrid arose. In 1928 William Judd, propagator at the time, collected seed from H. mollis. -

The botanical garden likes the cold but lively Swiss winter, by when it is embraced by the odorous witch hazels (Hamamelis mollis Oliver), dressed up by the shy snowdrops (Leucojum spp.), and kissed by the passionate saffron (Crocus spp.). Everything is just as beautiful as the the first sight we met, however, for me, it is the time to leave.
