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. -

TONY KIRKHAM writes about the exceptional collection of wild collected Chinese plants that thrive there 25 years on. 1987 can be remembered in the Dendrological calendar for a number of events in the tree world, particularly the Great Storm in the South-east of England that destroyed over 15 million trees in one night. This storm was a real wakeup call to anyone with even a slight interest in trees and it started a new beginning in the tree world, raising public awareness and generating new planting schemes across the UK. In the same year, in Sonoma Valley, California, Jane Davenport Jansen had a vision that would make significant additions to arboreta across the botanic garden world, and leave a living legacy that is now one of the largest living collections of wild collected temperate Asian plants in North America; it was the creation of Quarryhill Botanical Garden. In 1968, Jane purchased 61 acres in the foothills of the Mayacama Mountains off the Sonoma Highway in Glen Ellen, Sonoma County to be planted with vineyards, but 20 acres of the hillside contained several abandoned stone quarries and in 1987 she decided to create a garden. Unlike many gardens INTERNATIONAL DENDROLOGY SOCIETY GARDENS & ARBORETA that would be planted purely for landscape, aesthetic and floral qualities, Jane had set her sights on something unique to the area that would become her personal drive, a landscape planted with natural source plants derived from her own funded expeditions to targeted countries around the world with an emphasis on the Far East. -
Molecular Support for a Basal Grade of Morphologically
TAXON 60 (4) • August 2011: 941–952 Razafimandimbison & al. • A basal grade in the Vanguerieae alliance MOLECULAR PHYLOGENETICS AND BIOGEOGRAPHY Molecular support for a basal grade of morphologically distinct, monotypic genera in the species-rich Vanguerieae alliance (Rubiaceae, Ixoroideae): Its systematic and conservation implications Sylvain G. Razafimandimbison,1 Kent Kainulainen,1,2 Khoon M.

Box 392, Victoria, Mahé, Seychelles Author for correspondence: Sylvain G. Razafimandimbison, [email protected] Abstract Many monotypic genera with unique apomorphic characters have been difficult to place in the morphology-based classifications of the coffee family (Rubiaceae). We rigorously assessed the subfamilial phylogenetic position and generic status of three enigmatic genera, the Seychellois Glionnetia, the Southeast Asian Jackiopsis, and the Chinese Trailliaedoxa within Rubiaceae, using sequence data of four plastid markers (ndhF, rbcL, rps16, trnTF). The present study provides molecular phylogenetic support for positions of these genera in the subfamily Ixoroideae, and reveals the presence of a basal grade of morphologically distinct, monotypic genera (Crossopteryx, Jackiopsis, Scyphiphora, Trailliaedoxa, and Glionnetia, respectively) in the species-rich Vanguerieae alliance. These five genera may represent sole representatives of their respective lineages and therefore may carry unique genetic information. Their conservation status was assessed, applying the criteria set in IUCN Red List Categories. We consider Glionnetia and Jackiopsis Endangered. Scyphiphora is recognized as Near Threatened despite its extensive range and Crossopteryx as Least Concern. -

It is the only herbaceous semishrub of the family showing a disjunct distribution in eastern Asia and eastern North America, extending to Central America. Its phylogeny and biogeographical diversification remain poorly understood. In this study, we conducted phylogenetic and biogeographical analyses for Mitchella and its close relative Damnacanthus based on sequences of the nuclear internal transcribed spacer (ITS) and four plastid markers (rbcL, atpB-rbcL, rps16 and trnL-F). Mitchella is monophyletic, consisting of an eastern Asian M. undulata clade and a New World M. repens clade. Our results also support Michella as the closest relative to the eastern Asian Damnacanthus. The divergence time between the two intercontinental disjunct Mitchella species was dated to 7.73 Mya, with a 95% highest posterior density (HPD) of 3.14-12.53 Mya, using the Bayesian relaxed clock estimation. -
Living Collections Strategy 2019 Scoliopus Bigelovii Living Collections Strategy 1
Living Collections Strategy 2019 Scoliopus bigelovii Living Collections Strategy 1 Foreword The Royal Botanic Gardens, Kew has an extraordinary wealth of living plant collections across our two sites, Kew Gardens and Wakehurst. One of our key objectives as an organisation is that our collections should be curated to excellent standards and widely used for the benefit of humankind. In support of this fundamental objective, through development of this Living Collections Strategy, we are providing a blueprint for stronger alignment and integration of Kew’s horticulture, science and conservation into the future. The Living Collections have their origins in the eighteenth century but have been continually developing and growing since that time. Significant expansion occurred during the mid to late 1800s (with the extension of British influence globally and the increase in reliable transport by sea) and continued into the 1900s. In recent years, a greater emphasis has been placed on the acquisition of plants of high conservation value, where the skills and knowledge of Kew’s staff have been critically important in unlocking the secrets vital for the plants’ survival. Held within the collections are plants of high conservation value (some extinct in the wild), representatives of floras from different habitats across the world, extensive taxonomically themed collections of families or genera, plants that are useful to humankind, and plants that contribute to the distinctive landscape characteristics of our two sites. In this strategy, we have sought to bring together not only the information about each individual collection, but also the context and detail of the diverse growing environments, development of each collection, significant species, and areas of policy and protocol such as the application of the Convention on International Trade in Endangered Species of Wild Fauna and Flora, the Convention on Biological Diversity and biosecurity procedures. -

This work is licensed under the Creative Commons Attribution International License (CC BY). http://creativecommons.org/licenses/by/4.0/ Abstract This study is a review of the Condamineeae tribe, through the acquisition of data from phyto- chemical studies and evaluation of genera activities that constitute the tribe, in order to contri- bute to chemotaxonomic classification of this tribe in the Rubiaceae family. This review also states the scarcity of phytochemical investigations of several genera and consequently a lot of species of family. Keywords Biological Activity, Condamineeae, Chemotaxomy, Phytochemistry, Rubiaceae 1. Introduction The Rubiaceae family has approximately 660 genus and around 11,150 species [1]. Based on molecular phylo- genetic studies [2] [3] this family is partitioned in three subfamilies: Cinchonoideae, Ixoroideae and Rubioideae. It is widely distributed, mainly on tropical and subtropical regions but also on cold and temperate regions in Europe and north of Canada [4]. In America this family is represented by approximately 229 genus and 5200 species [5]. Nowadays it has around 118 genus and 1347 species in Brazil, corresponding to one of the main families of Brazilian flora [6].
