Cryptocarya of Thedirectorategeneral for Cryptocarya Development Cooperation , a Large, Pantropical Genus of Genus Pantropical Large, a , Cryptocarya Species
Taxonomy of Cryptocarya species of Brazil Taxonomy of Cryptocarya This revision of Brazilian species of Cryptocarya, a large, pantropical genus of species of Brazil Lauraceae, comes highly recommended. Lauraceae is an extensive family of trees that has remained poorly studied because large trees with small fl owers are often ignored by fi eld workers. In a time when so much botanical research is focused on relationships between taxa, it is refreshing to see such a detailed work on species delimitation in a previously inaccessible group. Everything one could want to know about neotropical Cryptocarya species is included: keys, descriptions, illustrations, use, etc. In short, this is a monograph in the classical sense. Pedro L.R. de Moraes The author has studied the species extensively in the fi eld and this fi eld knowledge adds much to the value of this taxonomic review and sets it apart from most revisions that often are largely based on studies of dried specimens. Here, detailed discussions of fi eld characters and photographs of fresh specimens are aptly integrated. In conclusion, this is an excellent contribution to our knowledge of Lauraceae and the author is to be congratulated. One could only wish for more publications on the same high level!

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.

Status of Red Panda in Sikkim: a Case Study in East Sikkim
STATUS OF RED PANDA IN SIKKIM: A CASE STUDY IN EAST SIKKIM Partha S. Ghose, Basant K. Sharma, Rajarshi Chakraborty and Karma Legshey D. ABSTRACT ed panda is the state animal of Sikkim and its population in the wild is highly vulnerable globally. Very little is known about red panda from Sikkim. With this background in mind the present collaborative survey by WWF- RIndia and Forest Environment and Wildlife Management Department, Government of Sikkim was initiated since 2005 to understand red panda's status in the wild and threats they are exposed to. The present work was conducted at three protected areas of East District and the results were subsequently used to assess the extent of red panda habitat in East District. Our results show that bamboo presence and cover emerged as the essential habitat feature to support red panda population. Among forest types mixed conifer was best suited for red pandas, followed by oak forests. However, conifer forest unlike the most beliefs did not emerge as the best possible habitat feature. The threat issues observed during the survey were discussed. KEYWORDS: Red panda, Sikkim, mixed conifer, oak forest, feral dogs, threats Red Panda photographed at Chowkidara Phedi-Pangolakha Wild Life Sanctuary 363 Red panda sighted at Pangolakha Ridge Top INTRODUCTION ed panda is a unique carnivore that has adapted to the herbivore mode of life and is a resident of Himalayan and Hengduan mountain ranges (Roberts and Gittleman, 1984; Glatston, 1994; Wei et al., 1999; Chowdhury, 2001). RLike its phylogenetic position, status of the red panda in wild has also been a matter of great discussion and speculation for over a long period (Glatston, 1994). -

Fl. China 11: 516–553. 2008. 2. ACER Linnaeus, Sp. Pl. 2: 1054. 1753. 枫属 feng shu Trees or shrubs. Leaves mostly simple and palmately lobed or at least palmately veined, in a few species pinnately veined and entire or toothed, or pinnately or palmately 3–5-foliolate. Inflorescence corymbiform or umbelliform, sometimes racemose or large paniculate. Sepals (4 or)5, rarely 6. Petals (4 or)5, rarely 6, seldom absent. Stamens (4 or 5 or)8(or 10 or 12); filaments distinct. Carpels 2; ovules (1 or)2 per locule. Fruit a winged schizocarp, commonly a double samara, usually 1-seeded; embryo oily or starchy, radicle elongate, cotyledons 2, green, flat or plicate; endosperm absent. 2n = 26. About 129 species: widespread in both temperate and tropical regions of N Africa, Asia, Europe, and Central and North America; 99 species (61 endemic, three introduced) in China. Acer lanceolatum Molliard (Bull. Soc. Bot. France 50: 134. 1903), described from Guangxi, is an uncertain species and is therefore not accepted here. The type specimen, in Berlin (B), has been destroyed. Up to now, no additional specimens have been found that could help clarify the application of this name. Worldwide, Japanese maples are famous for their autumn color, and there are over 400 cultivars. Also, many Chinese maple trees have beautiful autumn colors and have been cultivated widely in Chinese gardens, such as Acer buergerianum, A. davidii, A. duplicatoserratum, A. griseum, A. pictum, A. tataricum subsp. ginnala, A. triflorum, A. truncatum, and A. wilsonii. In winter, the snake-bark maples (A. davidii and its relatives) and paper-bark maple (A. -

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. -

Wa Shan – Emei Shan, a Further Comparison
photograph © Zhang Lin A rare view of Wa Shan almost minus its shroud of mist, viewed from the Abies fabri forested slopes of Emei Shan. At its far left the mist-filled Dadu River gorge drops to 500-600m. To its right the 3048m high peak of Mao Kou Shan climbed by Ernest Wilson on 3 July 1903. “As seen from the top of Mount Omei, it resembles a huge Noah’s Ark, broadside on, perched high up amongst the clouds” (Wilson 1913, describing Wa Shan floating in the proverbial ‘sea of clouds’). Wa Shan – Emei Shan, a further comparison CHRIS CALLAGHAN of the Australian Bicentennial Arboretum 72 updates his woody plants comparison of Wa Shan and its sister mountain, World Heritage-listed Emei Shan, finding Wa Shan to be deserving of recognition as one of the planet’s top hotspots for biological diversity. The founding fathers of modern day botany in China all trained at western institutions in Europe and America during the early decades of last century. In particular, a number of these eminent Chinese botanists, Qian Songshu (Prof. S. S. Chien), Hu Xiansu (Dr H. H. Hu of Metasequoia fame), Chen Huanyong (Prof. W. Y. Chun, lead author of Cathaya argyrophylla), Zhong Xinxuan (Prof. H. H. Chung) and Prof. Yung Chen, undertook their training at various institutions at Harvard University between 1916 and 1926 before returning home to estab- lish the initial Chinese botanical research institutions, initiate botanical exploration and create the earliest botanical gardens of China (Li 1944). It is not too much to expect that at least some of them would have had personal encounters with Ernest ‘Chinese’ Wilson who was stationed at the Arnold Arboretum of Harvard between 1910 and 1930 for the final 20 years of his life. -
SF Street Tree Species List 2019
Department of Public Works 2019 Recommended Street Tree Species List 1 Introduction The San Francisco Urban Forestry Council periodically reviews and updates this list of trees in collaboration with public and non-profit urban forestry stakeholders, including San Francisco Public Works, Bureau of Urban Forestry and Friends of the Urban Forest. The 2019 Street Tree List was approved by the Urban Forestry Council on October 22, 2019. This list is intended to be used for the public realm of streets and associated spaces and plazas that are generally under the jurisdiction of the Public Works. While the focus is on the streetscape, e.g., tree wells in the public sidewalks, the list makes accommodations for these other areas in the public realm, e.g., “Street Parks.” While this list recommends species that are known to do well in many locations in San Francisco, no tree is perfect for every potential tree planting location. This list should be used as a guideline for choosing which street tree to plant but should not be used without the help of an arborist or other tree professional. All street trees must be approved by Public Works before planting. Sections 1 and 2 of the list are focused on trees appropriate for sidewalk tree wells, and Section 3 is intended as a list of trees that have limited use cases and/or are being considered as street trees. Finally, new this year, Section 4, is intended to be a list of local native tree and arborescent shrub species that would be appropriate for those sites in the public realm that have more space than the sidewalk planting wells, for example, stairways, “Street Parks,” plazas, and sidewalk gardens, where more concrete has been extracted. -
2 HISTORICAL ROLE of PALMS in HUMAN CULTURE Ancient and Traditional Palm Products
Tropical Palms 13 2 HISTORICAL ROLE OF PALMS IN HUMAN CULTURE Pre-industrial indigenous people of the past as well as of the present have an intimate and direct relationship with the renewable natural resources of their environment. Prior to the Industrial Age, wild and cultivated plants and wild and domesticated animals provided all of the food and most of the material needs of particular groups of people. Looking back to those past times it is apparent that a few plant families played a prominent role as a source of edible and nonedible raw materials. For the entire world, three plant families stand out in terms of their past and present utility to humankind: the grass family (Gramineae), the legume family (Leguminosae) and the palm family (Palmae). If the geographic focus is narrowed to the tropical regions, the importance of the palm family is obvious. The following discussion sets out to provide an overview of the economic importance of palms in earlier times. No single comprehensive study has yet been made of the historical role of palms in human culture, making this effort more difficult. A considerable amount of information on the subject is scattered in the anthropological and sociological literature as part of ethnographic treatments of culture groups throughout the tropics. Moreover, historical uses of products from individual palm species can be found in studies of major economic species such as the coconut or date palms. It should also be noted that in addition to being highly utilitarian, palms have a pivotal role in myth and ritual in certain cultures.
