  • Outline of Angiosperm Phylogeny
    Outline of angiosperm phylogeny: orders, families, and representative genera with emphasis on Oregon native plants Priscilla Spears December 2013 The following listing gives an introduction to the phylogenetic classification of the flowering plants that has emerged in recent decades, and which is based on nucleic acid sequences as well as morphological and developmental data. This listing emphasizes temperate families of the Northern Hemisphere and is meant as an overview with examples of Oregon native plants. It includes many exotic genera that are grown in Oregon as ornamentals plus other plants of interest worldwide. The genera that are Oregon natives are printed in a blue font. Genera that are exotics are shown in black, however genera in blue may also contain non-native species. Names separated by a slash are alternatives or else the nomenclature is in flux. When several genera have the same common name, the names are separated by commas. The order of the family names is from the linear listing of families in the APG III report. For further information, see the references on the last page. Basal Angiosperms (ANITA grade) Amborellales Amborellaceae, sole family, the earliest branch of flowering plants, a shrub native to New Caledonia – Amborella Nymphaeales Hydatellaceae – aquatics from Australasia, previously classified as a grass Cabombaceae (water shield – Brasenia, fanwort – Cabomba) Nymphaeaceae (water lilies – Nymphaea; pond lilies – Nuphar) Austrobaileyales Schisandraceae (wild sarsaparilla, star vine – Schisandra; Japanese

  • Agave Americana and Furcraea Andina: Key Species to Andean Cultures in Ecuador
    Ethnobotany Agave americana and Furcraea andina: Key Species to Andean Cultures in Ecuador LUCÍA DE LA TORRE1*, IAN CUMMINS2, AND ELIOT LOGAN-HINES2 Botanical Sciences 96 (2): 246-266, 2018 Abstract Background: The rich Agaveae-based culture that exists in the Ecuadorian Andes is little known. Wild DOI: 10.17129/botsci.1813 and cultivated rosettes of Agave americana and Furcraea andina coexist in arid Andean landscapes. A. americana is considered an introduced species to Ecuador.

Is the ethno- December 19th, 2017 Accepted: botanical significance of Agave in Ecuador comparable to that in Mexico and other Andean countries? Agave americana, Furcraea andina March 12th, 2018 Species studied: Associated editor: Study site, dates: Ecuadorian Andes, 2016. Salvadro Arias Methods: Semi-structured interviews to Agaveae users (37) and a review of literature on ethnobotanical research conducted in Ecuador since the 18th century. Results: A. americana is more diversely and widely used than F. andina (124 vs 36 uses and 548 vs 140 use records, respectively). The versatility of A. americana lies in its mishki (sap extracted from its heart) which has multiple medicinal, edible and ceremonial applications. We found significant variation of its use patterns throughout the region. The main use of F. andina as a source of fiber is disappearing. Most productive initiatives involve A. americana (92 %, n = 53). Conclusion: The importance of A. americana in the Ecuadorian Andes is comparable to that of agaves in Mexico, but not to its importance in other Andean countries where it is used sporadically.

Chris Pires Dr. Lori Eggert Dr. Candace Galen Dr. Rose‐Marie Muzika ACKNOWLEDGEMENTS I am indebted to many people for their assistance during the course of my graduate education. I would not have derived such a keen understanding of the learning process without the tutelage of Dr. Sandi Abell. Members of the Pires lab provided prolific support in improving lab techniques, computational analysis, greenhouse maintenance, and writing support. Team Monocot, including Dr. Mike Kinney, Dr. Roxi Steele, and Erica Wheeler were particularly helpful, but other lab members working on Brassicaceae (Dr. Zhiyong Xiong, Dr. Maqsood Rehman, Pat Edger, Tatiana Arias, Dustin Mayfield) all provided vital support as well. I am also grateful for the support of a high school student, Cady Anderson, and an undergraduate, Tori Docktor, for their assistance in laboratory procedures. Many people, scientist and otherwise, helped with field collections: Dr. Travis Columbus, Hester Bell, Doug and Judy McGoon, Julie Ketner, Katy Klymus, and William Alexander. Many thanks to Barb Sonderman for taking care of my greenhouse collection of many odd plants brought back from the field.

  • Exploiting the Potential of Agave for Bioenergy in Marginal Lands Dalal
    Exploiting the Potential of Agave for Bioenergy in Marginal Lands Dalal Bader Al Baijan A Thesis submitted for the Degree of Doctor of Philosophy School of Biology Newcastle University July 2015 Declaration I hereby certify that this thesis is the result of my own investigations and that no part of it has been submitted for any degree other than Doctor of Philosophy at the Newcastle University. All references to the work of others have been duly acknowledged. Dalal B. Al Baijan ii “It is not the strongest of the species that survives, nor the most intelligent, but the one most responsive to change” Charles Darwin Origin of Species, 1859 iii Abstract Drylands cover approximately 40% of the global land area, with minimum rainfall levels, high temperatures in the summer months, and they are prone to degradation and desertification. Drought is one of the prime abiotic stresses limiting crop production. Agave plants are known to be well adapted to dry, arid conditions, producing comparable amounts of biomass to the most water-use efficient C3 and C4 crops but only require 20% of water for cultivation, making them good candidates for bioenergy production from marginal lands. Agave plants have high sugar contents, along with high biomass yield. More importantly, Agave is an extremely water-use efficient (WUE) plant due to its use of Crassulacean acid metabolism. Most of the research conducted on Agave has centered on A. tequilana due to its economic importance in the tequila production industry. However, there are other species of Agave that display higher biomass yields compared to A.

An increasing number is escaping and naturalising, also in natural habitats in the Canary Islands (Spain). However, a detailed treatment of variously naturalised and invasive species found in the wild in the Canary Islands is not available and, as a result, species identification is often problematic.
