THE Magnoliaceae Liriodendron L. Magnolia L
THE Magnoliaceae Liriodendron L. Magnolia L. VEGETATIVE KEY TO SPECIES IN CULTIVATION Jan De Langhe (1 October 2014 - 28 May 2015) Vegetative identification key. Introduction: This key is based on vegetative characteristics, and therefore also of use when flowers and fruits are absent. - Use a 10× hand lens to evaluate stipular scars, buds and pubescence in general. - Look at the entire plant. Young specimens, shade, and strong shoots give an atypical view. - Beware of hybridisation, especially with plants raised from seed other than wild origin. Taxa treated in this key: see page 10. Questionable/frequently misapplied names: see page 10. Names referred to synonymy: see page 11.

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. -

THE GIANT PANDA (Ailuropoda Melanoleuca): a BIBLIOGRAPHY (1936-1994)
TITLE: THE GIANT PANDA (Ailuropoda melanoleuca): A BIBLIOGRAPHY (1936-1994). AUTHOR & INSTITUTION: Kay A. Kenyon, Librarian National Zoological Park Branch Smithsonian Institution Libraries Washington, DC DATE: November 1984 LAST UPDATE: January 1995 INTRODUCTION The following bibliography of the giant panda (Ailuropoda melanoleuca) is for the research scientist, but is useful for anyone interested in pandas. It includes popular as well as serious scientific works in foreign languages as well as in English. References cover all aspects of the giant panda--its discovery, evolution, physiology, anatomy, behavior, reproduction, feeding habits, and diseases. This bibliography is divided into four sections and is arranged alphabetically by author. Both articles and books are included. The first section begins in 1936 when the first giant panda, Su-Lin, was brought to the United States and covers the next two decades (1936-1956). The second section covers the next 20 years (1957-1977). During this period more giant pandas found their way to the Western World--Chi-Chi at the London Zoo, An-An at the Moscow Zoo, Ying-Ying and Pe-Pe at the Mexican Zoo. Chia-Chia and Ching-Ching at the London Zoo, and of course, our own famous pandas, Ling-Ling and Hsing-Hsing at the National Zoo*. The third section covers the years 1978-1989 and the fourth section begins in 1990 and brings us to the present. * Hsing-Hsing, the female panda at the National Zoo died of heart failure in 1993. 1936-1956 . page 2 1957-1977 . page 7 1978-1989 . page 14 1990-1994 . page 24 1 1935-1956 Allen, C.M. -
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. -

The Progressive and Ancestral Traits of the Secondary Xylem Within Magnolia Clad – the Early Diverging Lineage of Flowering Plants
Acta Societatis Botanicorum Poloniae ORIGINAL RESEARCH PAPER Acta Soc Bot Pol 84(1):87–96 DOI: 10.5586/asbp.2014.028 Received: 2014-07-31 Accepted: 2014-12-01 Published electronically: 2015-01-07 The progressive and ancestral traits of the secondary xylem within Magnolia clad – the early diverging lineage of flowering plants Magdalena Marta Wróblewska* Department of Developmental Plant Biology, Institute of Experimental Biology, University of Wrocław, Kanonia 6/8, 50-328 Wrocław, Poland Abstract The qualitative and quantitative studies, presented in this article, on wood anatomy of various species belonging to ancient Magnolia genus reveal new aspects of phylogenetic relationships between the species and show evolutionary trends, known to increase fitness of conductive tissues in angiosperms. They also provide new examples of phenotypic plasticity in plants. The type of perforation plate in vessel members is one of the most relevant features for taxonomic studies. InMagnolia , until now, two types of perforation plates have been reported: the conservative, scalariform and the specialized, simple one. In this paper, are presented some findings, new to magnolia wood science, like exclusively simple perforation plates in some species or mixed perforation plates – simple and scalariform in one vessel member. Intravascular pitting is another taxonomically important trait of vascular tissue. Interesting transient states between different patterns of pitting in one cell only have been found. This proves great flexibility of mechanisms, which elaborate cell wall structure in maturing trache- ary element. The comparison of this data with phylogenetic trees, based on the fossil records and plastid gene expression, clearly shows that there is a link between the type of perforation plate and the degree of evolutionary specialization within Magnolia genus. -
Catholic Missionaries on China's Qinling Shu Roads
Catholic Missionaries on China’s Qinling Shu Roads: Including an account of the Hanzhong Mission at Guluba David L B Jupp URL: http://qinshuroads.org/ September 2012. Addenda & Corrigenda: November 2013, April 2015, July 2016 & January 2018. Minor edits January 2020. Abstract: The background to this document is found in the history of China’s Shu Roads that passed through the Qinling and Ba Mountains for many years. The roads have linked the northern and southern parts of western China since the earliest records and probably before. In all that time, the common description of the Shu roads was that they were “hard”. In the Yuan, Ming and Qing periods when China was open and accessible, foreign travellers visited the Shu Roads and some left accounts of their travels. Among the early travellers were Catholic Missionaries who moved into the west of China to spread Christianity. This document first outlines the historical environment of the open periods and then identifies various events and Catholic Priests who seem to have travelled the Shu Roads or have left descriptions that are of interest today. The main focus of this document is on the recorded experiences of Missionaries mostly from the Jesuit, Franciscan and Vincentian orders of the Catholic Church of Rome who travelled to the Hanzhong Basin. The main items include: Marco Polo’s (circa 1290) account of travels in China which many Priests who arrived later had read to find out about China; Jesuit Fr. Étienne Faber’s travels to Hanzhong in 1635; Jesuit Fr. Martino Martini’s description of Plank Roads in his Atlas of China in 1655; Franciscan Fr.
