  • Appendix Color Plates of Solanales Species
    Appendix Color Plates of Solanales Species The first half of the color plates (Plates 1–8) shows a selection of phytochemically prominent solanaceous species, the second half (Plates 9–16) a selection of convol- vulaceous counterparts. The scientific name of the species in bold (for authorities see text and tables) may be followed (in brackets) by a frequently used though invalid synonym and/or a common name if existent. The next information refers to the habitus, origin/natural distribution, and – if applicable – cultivation. If more than one photograph is shown for a certain species there will be explanations for each of them. Finally, section numbers of the phytochemical Chapters 3–8 are given, where the respective species are discussed. The individually combined occurrence of sec- ondary metabolites from different structural classes characterizes every species. However, it has to be remembered that a small number of citations does not neces- sarily indicate a poorer secondary metabolism in a respective species compared with others; this may just be due to less studies being carried out.

Austin Arizona-Sonora Desert Museum, 2021 North Kinney Road, Tucson, AZ 85743, USA Received 23 October 2007; received in revised form 28 January 2008; accepted 29 January 2008 Available online 12 February 2008 Abstract People in the Indian region often apply shankhapushpi and vishnukranti, two Sanskrit-based common names, to Evolvulus alsinoides. These are pre-European names that are applied to a medicinal American species transported into the area. The period of introduction is uncertain, but probably took place in the 1500s or 1600s. Examination of relationships of Evolvulus alsinoides, geographic distribution, its names in Asia, medical uses, and chemical and laboratory analysis indicates that the alien plant was adopted, given an ancient Indian name, and incorporated into some Old World pharmacopoeias. The herb apparently was included in medicines because it not only reminded people of certain aspects of their gods and goddesses, but also because the chemicals it contained were useful against some maladies.

  • BIODIVERSITY CONSERVATION on the TIWI ISLANDS, NORTHERN TERRITORY: Part 1. Environments and Plants
    BIODIVERSITY CONSERVATION ON THE TIWI ISLANDS, NORTHERN TERRITORY: Part 1. Environments and plants Report prepared by John Woinarski, Kym Brennan, Ian Cowie, Raelee Kerrigan and Craig Hempel. Darwin, August 2003 Cover photo: Tall forests dominated by Darwin stringybark Eucalyptus tetrodonta, Darwin woollybutt E. miniata and Melville Island Bloodwood Corymbia nesophila are the principal landscape element across the Tiwi islands (photo: Craig Hempel). i SUMMARY The Tiwi Islands comprise two of Australia’s largest offshore islands - Bathurst (with an area of 1693 km 2) and Melville (5788 km 2) Islands. These are Aboriginal lands lying about 20 km to the north of Darwin, Northern Territory. The islands are of generally low relief with relatively simple geological patterning. They have the highest rainfall in the Northern Territory (to about 2000 mm annual average rainfall in the far north-west of Melville and north of Bathurst). The human population of about 2000 people lives mainly in the three towns of Nguiu, Milakapati and Pirlangimpi. Tall forests dominated by Eucalyptus miniata, E. tetrodonta, and Corymbia nesophila cover about 75% of the island area. These include the best developed eucalypt forests in the Northern Territory. The Tiwi Islands also include nearly 1300 rainforest patches, with floristic composition in many of these patches distinct from that of the Northern Territory mainland. Although the total extent of rainforest on the Tiwi Islands is small (around 160 km 2 ), at an NT level this makes up an unusually high proportion of the landscape and comprises between 6 and 15% of the total NT rainforest extent. The Tiwi Islands also include nearly 200 km 2 of “treeless plains”, a vegetation type largely restricted to these islands.

  • Classification of Convolvulaceae: a Phylogenetic Approach

Third Street, Bloomington, Indiana, 47405 ([email protected]) Communicating Editor: Paul S. Manos ABSTRACT. Because recent molecular studies, based on multiple data sets from all three plant genomes, have indicated mutually congruent, well-resolved, and well-supported relationships within Convolvulaceae (the morning-glory family), a formal reclassi®cation of this family is presented here. Convolvulaceae, a large family of worldwide distribution, exhibiting a rich diversity of morphological characteristics and ecological habitats, are now circumscribed within twelve tribes. A key to these tribes of Convolvulaceae is offered. The group of spiny-pollen bearing Convolvulaceae (forming ``Echinoconiae'') and tribe Cuscuteae are retained essentially in their traditional sense, Cresseae are circumscribed with only minor modi®- cations, Convolvuleae and Erycibeae are recognized in a restricted sense, while Dichondreae and Maripeae are expanded. Also, to produce a tribal taxonomy that better re¯ects phylogenetic relationships, the concept of Poraneae is abandoned as arti®cial, three new tribes are recognized (Aniseieae, Cardiochlamyeae, and Jacquemontieae), and a new tribal status is proposed for the Malagasy endemic Humbertia (Humbertieae). ``Merremieae'' are tentatively retained even though the mono- phyly of this tribe is not certain.

  • Biodiversity Summary: Cape York, Queensland
    Biodiversity Summary for NRM Regions Species List What is the summary for and where does it come from? This list has been produced by the Department of Sustainability, Environment, Water, Population and Communities (SEWPC) for the Natural Resource Management Spatial Information System. The list was produced using the AustralianAustralian Natural Natural Heritage Heritage Assessment Assessment Tool Tool (ANHAT), which analyses data from a range of plant and animal surveys and collections from across Australia to automatically generate a report for each NRM region. Data sources (Appendix 2) include national and state herbaria, museums, state governments, CSIRO, Birds Australia and a range of surveys conducted by or for DEWHA. For each family of plant and animal covered by ANHAT (Appendix 1), this document gives the number of species in the country and how many of them are found in the region. It also identifies species listed as Vulnerable, Critically Endangered, Endangered or Conservation Dependent under the EPBC Act. A biodiversity summary for this region is also available. For more information please see: www.environment.gov.au/heritage/anhat/index.html Limitations • ANHAT currently contains information on the distribution of over 30,000 Australian taxa. This includes all mammals, birds, reptiles, frogs and fish, 137 families of vascular plants (over 15,000 species) and a range of invertebrate groups. Groups notnot yet yet covered covered in inANHAT ANHAT are notnot included included in in the the list. list. • The data used come from authoritative sources, but they are not perfect. All species names have been confirmed as valid species names, but it is not possible to confirm all species locations.
