  • IUCN Red List of Threatened Species™ to Identify the Level of Threat to Plants
    Ex-Situ Conservation at Scott Arboretum Public gardens and arboreta are more than just pretty places. They serve as an insurance policy for the future through their well managed ex situ collections. Ex situ conservation focuses on safeguarding species by keeping them in places such as seed banks or living collections. In situ means "on site", so in situ conservation is the conservation of species diversity within normal and natural habitats and ecosystems. The Scott Arboretum is a member of Botanical Gardens Conservation International (BGCI), which works with botanic gardens around the world and other conservation partners to secure plant diversity for the benefit of people and the planet. The aim of BGCI is to ensure that threatened species are secure in botanic garden collections as an insurance policy against loss in the wild. Their work encompasses supporting botanic garden development where this is needed and addressing capacity building needs. They support ex situ conservation for priority species, with a focus on linking ex situ conservation with species conservation in natural habitats and they work with botanic gardens on the development and implementation of habitat restoration and education projects. BGCI uses the IUCN Red List of Threatened Species™ to identify the level of threat to plants. In-depth analyses of the data contained in the IUCN, the International Union for Conservation of Nature, Red List are published periodically (usually at least once every four years). The results from the analysis of the data contained in the 2008 update of the IUCN Red List are published in The 2008 Review of the IUCN Red List of Threatened Species; see www.iucn.org/redlist for further details.

  • Relora-Plex Supports a Healthy Stress Response†
    PRODUCT DATA DOUGLAS LABORATORIES® 07/2015 1 Relora-Plex Supports a Healthy Stress Response† DESCRIPTION Relora-Plex is a unique proprietary blend of two herbal extracts, Magnolia and Phellodendron, combined with B vitamins designed to support normal mental functioning during stress. Relora® was shown in published clinical studies to support normal salivary cortisol levels, stress, mood, and weight management.† FUNCTIONS Cortisol, a hormone produced in the adrenal glands, plays an important role in the body’s regulation of cardiovascular function and fat, protein and carbohydrate utilization. When the body experiences stress, cortisol secretion increases, thus causing a breakdown of muscle protein and the release of amino acids to form glucose via gluconeogenesis. The resulting higher level of glucose in the body, combined with the decreased use of glucose by other tissues in the body, ensures that the brain is receiving adequate energy. Continuing research indicates that stress and anxiety can have a significant impact on the body’s health and wellbeing. While cortisol secretion is an important part of the body’s response to stress, the prolonged secretion of cortisol can have detrimental effects to the proper functioning of the body’s cardiovascular, immune, neurological and metabolic systems. Relora® is a patent-pending combination of two herbal extracts of Magnolia and Phellodendron bark (Asian cork tree). Both herbs have been used in Traditional Chinese Medicine for several hundred years. In a human study, 82% of the participants taking Relora® agreed with the statement that: “Relora® helps control…. irritability, emotional ups and downs, restlessness, tense muscles, poor sleep, fatigue, and concentration difficulties.”* † Relora® was found not to cause sedation, though 74% of the patients had more restful sleep.

  • Magnolia Obovata
    ISSUE 80 INAGNOLN INagnolla obovata Eric Hsu, Putnam Fellow, Arnold Arboretum of Harvard University Photographs by Philippe de 8 poelberch I first encountered Magnolia obovata in Bower at Sir Harold Hillier Gardens and Arboretum, Hampshire, England, where the tightly pursed, waxy, globular buds teased, but rewarded my patience. As each bud unfurled successively, it emitted an intoxicating ambrosial bouquet of melons, bananas, and grapes. Although the leaves were nowhere as luxuriously lustrous as M. grandrflora, they formed an el- egant wreath for the creamy white flower. I gingerly plucked one flower for doser observation, and placed one in my room. When I re- tumed from work later in the afternoon, the mom was overpowering- ly redolent of the magnolia's scent. The same olfactory pleasure was later experienced vicariously through the large Magnolia x wiesneri in the private garden of Nicholas Nickou in southern Connecticut. Several years earlier, I had traveled to Hokkaido Japan, after my high school graduation. Although Hokkaido experiences more severe win- ters than those in the southern parts of Japan, the forests there yield a remarkable diversity of fora, some of which are popular ornamen- tals. When one drives through the region, the silvery to blue-green leaf undersides of Magnolia obovata, shimmering in the breeze, seem to flag the eyes. In "Forest Flora of Japan" (sggII), Charles Sargent commended this species, which he encountered growing tluough the mountainous forests of Hokkaido. He called it "one of the largest and most beautiful of the deciduous-leaved species in size and [the seed conesj are sometimes eight inches long, and brilliant scarlet in color, stand out on branches, it is the most striking feature of the forests.

  • The Progressive and Ancestral Traits of the Secondary Xylem Within Magnolia Clad – the Early Diverging Lineage of Flowering Plants

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.

  • Magnolia Wilsonii Bill Mcnamara, Executive Director Quarrytu'll Botanic Garden
    Nagnolia Issue 88 Endangered: Magnolia wilsonii Bill McNamara, Executive Director Quarrytu'll Botanic Garden My choice for a favorite tree seems to change almost weekly, sometimes even daily. But one has currently held my impatient mind longer than normal. It is a tree with so many admirable qualities that I think everyone should try to find a place for it in their gardens. Though widely available in the nursery trade, it is also a tree that may soon be extinct in the wild. Imagine a tree that blooms after the danger of frosts, has pristine white 12-centimeter-wide flowers with brilliant crimson-red stamens that hang like bright lantern, has an elegant rich fragrance, doesn't get too big, and is named after the indefatigable plant hunter, E. H. Wilson. Of course, I'm thinking of Magnolia milsanii (Finet & Gagnep. ) Rehder, an endangered tree native to China occurring in western Sichuan, northern Yunnan and western Guizhou. Habitat loss and fragmentation have caused its num- bers in the wild to decrease to a dangerously low level. It is found in mixed forests between 1900 and 3300 meters elevation. Much of its habi- tat, once one of the richest temperate forests on earth, has been reduced to small areas too steep to clear for agriculture. Another threat to its sur- vival in the wild is demand for its bark due to its medicinal qualities. It is frequently used as a substitute for the bark of Magnolia officinalis. For centuries in China bark from several magnolia species has been used to clear head and chest congestion and for intestinal relief, while flower buds of many species have been used for sinus congestion.
