Plant ID Tools and Tricks Lynda Garvin Agriculture Agent Sandoval County Cooperative Extension Lgarvin@Nmsu.Edu 1/27/2016 Plant ID Tools and Tricks Lynda Garvin Agriculture Agent Sandoval County Cooperative Extension [email protected] Why is it useful? You may want to learn what’s native to your area so you can watch for invasive species. You may want to monitor the diversity of plants in your area – is it on the decline? are you working to improve it? You may take delight in the beauty of flowers or the majesty of trees. You may already be a bird watcher and now you want to know the names of the plants that are hospitable to birds. You may simply want to know the names of the living things in your surroundings. You’ll need to know the plant families for vegetable rotations Is a rose always a rose? Rose of Sharon ≠ It’s not a rose at all but in the mallow family: Hollyhocks Hibiscus Okra Cotton Cacao Kola Nuts Baobab Trees 1 1/27/2016 Taxonomy Taxonomy is the science of systematically naming and organizing organisms into groups using similar patterns. Systematics -- The study of diversity (taxonomy) and the history of organisms and the evolutionary relationships between them. Taxonomy of Living Things The basic categories are: Kingdom (Plantae, Animalia, Fungi…) Division (Phylum for animals) Class Order Family Genus Species Increasing degree of specificity – towards a single, definable, named species Plant Diversity in North America Plant Families - 210 Genera – 2,350 Species - 20,000+ 400,000 species have been described worldwide 2 1/27/2016 Nomenclature System by which plants are named. Common names. Scientific names. Carl Linnaeus (1707 –1778) Swedish MD & Botanist Binomial Nomenclature – the system we still use today Common Names Disadvantages Advantages No rules -- not Often descriptive consistent Easy to pronounce Applied to various Easy to remember taxonomic levels Familiar to people May not exist for some plants Use Common Names, Confusion reigns. Rabbitbrush 3 related genera of the family Asteraceae: with 17 species All called rabbitbrush. What is it’s common name in NM? 3 1/27/2016 Scientific Names Every plant gets one scientific name. The scientific name is a combination of the generic name and a specific name. Genus - Generic names Species - Specific name Names are in Latin. Italicized or underlined. Taxonomic Classification of NM Locust Kingdom: Plantae (plants) Division: Magnoliophyta (flowering plant) Class: Magnoliopsida (Dicot) Order: Fabales Family: Fabaceae (Leguminosae) Genus: Robinia Species: neomexicana Scientific Name (binomial nomenclature) Genus & species: Robinia neomexicana Robinia = Latin for locust tree Neomexicana = New Mexico Common name: New Mexican Locust Tool: Dictionary of Botanical Terms 4 1/27/2016 Where to start? Get out and look at plants, especially when they are in bloom! Look at their form: flowers, leaves, fruit, stems, etc. Study how they grow – upright, vining, prostrate… Where they grow (soils, sun, shade, neighboring plants, disturbed areas…) Sketch them Take photos Go to local botanical gardens The plants are already identified ☺ Get a buddy Go throughout the seasons What do you need? Carry a hand lens ID books Camera Note pad pen Plastic bags (Know where you can and cannot collect plants) 5 1/27/2016 Lets Get To It!

  • Full of Beans: a Study on the Alignment of Two Flowering Plants Classification Systems
    Full of beans: a study on the alignment of two flowering plants classification systems Yi-Yun Cheng and Bertram Ludäscher School of Information Sciences, University of Illinois at Urbana-Champaign, USA {yiyunyc2,ludaesch}@illinois.edu Abstract. Advancements in technologies such as DNA analysis have given rise to new ways in organizing organisms in biodiversity classification systems. In this paper, we examine the feasibility of aligning two classification systems for flowering plants using a logic-based, Region Connection Calculus (RCC-5) ap- proach. The older “Cronquist system” (1981) classifies plants using their mor- phological features, while the more recent Angiosperm Phylogeny Group IV (APG IV) (2016) system classifies based on many new methods including ge- nome-level analysis. In our approach, we align pairwise concepts X and Y from two taxonomies using five basic set relations: congruence (X=Y), inclusion (X>Y), inverse inclusion (X<Y), overlap (X><Y), and disjointness (X!Y). With some of the RCC-5 relationships among the Fabaceae family (beans family) and the Sapindaceae family (maple family) uncertain, we anticipate that the merging of the two classification systems will lead to numerous merged solutions, so- called possible worlds. Our research demonstrates how logic-based alignment with ambiguities can lead to multiple merged solutions, which would not have been feasible when aligning taxonomies, classifications, or other knowledge or- ganization systems (KOS) manually. We believe that this work can introduce a novel approach for aligning KOS, where merged possible worlds can serve as a minimum viable product for engaging domain experts in the loop. Keywords: taxonomy alignment, KOS alignment, interoperability 1 Introduction With the advent of large-scale technologies and datasets, it has become increasingly difficult to organize information using a stable unitary classification scheme over time.

  • Trees and Shrubs: Drought, Heat, Cold Tolerant Species
    Trees and Shrubs: Drought, Heat, Cold Tolerant Species This list of trees and shrubs is intended to provide guidance for choosing a tree or shrub which will grow in Las Vegas, New Mexico yards. This list of species is for residential yards, not City Parks which are regularly watered during the summer. Purpose. Before selecting a tree, think about the purposes of the tree you are going to plant: do you want it for shade, privacy screen, windbreak, beauty, wildlife value? Due to unpredictable late frosts, fruit producing trees are not recommended as a food source. For more information about what to look for buying a tree, watering, correct planting, watering, and pruning methods, read the Tree Owner’s Manual. A tree is an investment in both time and money. You can find the manual at http://na.fs.fed.us/pubs/uf/tom_natl/tree_owners_manual_web_res.pdf Site selection. Before buying a tree, determine where you are going to plant it, based on the purpose of the tree and these additional factors. Deciduous trees lose their leaves in the winter; if you plant them on the south and west side of your home, they will help with cooling during the summer. Because they lose their leaves, they allow winter sun to help warm your house. Reduce winds by planting trees and shrubs on the windy side of your home. Do not plant a tall tree near or under electric lines (height and width are listed in the descriptions). PNM recommends that a tree which is 25 feet tall at maturity be at least 15 feet from a power line; a 30 foot tall tree should be at least 30 feet away from a power line.

Hernández, Mario Sousa and Helga Ochoterena Herbario Nacional de México, Departamento de Botánica, Instituto de Biología, Universidad Nacional Autónoma de México. Apartado postal 70- 233, 04510 México D. F., Mexico. [email protected] Abstract. Trees or tree-like plants are defined here broadly as perennial, self-supporting plants with a total height of at least 5 m (without ascending leaves or inflorescences), and with one or several erect stems with a diameter of at least 10 cm. We continue our compilation of an updated list of all native Mexican tree species with the dicotyledonous families Asteraceae (36 species, 39% endemic), Leguminosae with its 3 subfamilies (449 species, 41% endemic), and Rubiaceae (134 species, 24% endemic). The tallest tree species reach 20 m in the Asteraceae, 70 m in the Leguminosae, and also 70 m in the Rubiaceae. The species-richest genus is Lonchocarpus with 67 tree species in Mexico. Three legume genera are endemic to Mexico (Conzattia, Hesperothamnus, and Heteroflorum). The appendix lists all species, including their original publication, references of taxonomic revisions, existence of subspecies or varieties, maximum height in Mexico, and endemism status. Key words: biodiversity, flora, tree definition. Resumen. Las plantas arbóreas o arborescentes se definen aquí en un sentido amplio como plantas perennes que se pueden sostener por sí solas, con una altura total de al menos 5 m (sin considerar hojas o inflorescencias ascendentes) y con uno o varios tallos erectos de un diámetro de al menos 10 cm.

The monophyly of the order is supported strongly by several studies, although interfamilial relationships are still poorly resolved and vary between studies; a situation common in higher level phylogenetic studies of ancient, rapid radiations. In this study, we carried out simulation analyses with previously published matK and rbcL regions. The results of our simulation analyses have shown that Fabales phylogeny can be solved and the 5,000 bp fast-evolving data type may be sufficient to resolve the Fabales phylogeny question. In our simulation analyses, while support increased as the sequence length did (up until a certain point), resolution showed mixed results. Interestingly, the accuracy of the phylogenetic trees did not improve with the increase in sequence length. Therefore, this study sounds a note of caution, with respect to interpreting the results of the “more data” approach, because the results have shown that large datasets can easily support an arbitrary root of Fabales. Keywords: Data type, Fabales, phylogeny, sequence length, simulation. 1. Introduction Fabales Bromhead is a cosmopolitan angiosperm order which consists of four families, Leguminosae (Fabaceae) Juss., Polygalaceae Hoffmanns.

(Fabales Fabaceae) two new legume records for natural flora of the United Arab Emirates Tamer Mahmoud 1* , Sanjay Gairola 1, Hatem Shabana 1 & Ali El-Keblawy 1, 2 1Sharjah Seed Bank and Herbarium, Sharjah Research Academy, Sharjah, United Arab Emirates 2Department of Applied Biology, Faculty of Science, University of Sharjah, Sharjah, United Arab Emirates Corresponding author, e-mail: [email protected] ABSTRACT In this report, we have recorded for the first time the presence of Sesbania bispinosa (Jacq.) W. Wight and Trifolium repens L. (Fabales Fabaceae) in natural flora of the United Arab Emirates (UAE). Based on extensive field surveys and literature review, it was apparent that these species have not been recorded before in the UAE flora.It might be important to mention that the two new records have great economic and agricultural importance. Both species are spontaneously occurring in the natural habitat and considered as good forage and can adapt to a wide range of environmental conditions. Specimens of both newly recoded species are deposited in the Sharjah Seed Bank and Herbarium (SSBH), UAE. Descriptions and photo - graphs of these species are provided. The new records of vascular plants in UAE flora would help ecologists and conservation biologists in more potential scientific research and natural resources exploitations.

  • Commodity Risk Assessment of Robinia Pseudoacacia Plants from Israel
    SCIENTIFIC OPINION ADOPTED: 30 January 2020 doi: 10.2903/j.efsa.2020.6039 Commodity risk assessment of Robinia pseudoacacia plants from Israel EFSA Panel on Plant Health (PLH), Claude Bragard, Katharina Dehnen-Schmutz, Francesco Di Serio, Paolo Gonthier, Marie-Agnes Jacques, Josep Anton Jaques Miret, Annemarie Fejer Justesen, Alan MacLeod, Christer Sven Magnusson, Panagiotis Milonas, Juan A Navas-Cortes, Stephen Parnell, Philippe Lucien Reignault, Hans-Hermann Thulke, Wopke Van der Werf, Antonio Vicent Civera, Jonathan Yuen, Lucia Zappala, Elisavet Chatzivassiliou, Jane Debode, Charles Manceau, Eduardo de la Pena,~ Ciro Gardi, Olaf Mosbach-Schulz, Stefano Preti and Roel Potting Abstract The EFSA Panel on Plant Health was requested to prepare and deliver risk assessments for commodities listed in the relevant Implementing Acts as ‘High risk plants, plant products and other objects’ [Commission Implementing Regulation (EU) 2018/2019 establishing a provisional list of high risk plants, plant products or other objects, within the meaning of Article 42 of Regulation (EU) 2016/2031]. The current Scientific Opinion covers all plant health risks posed by bare rooted plants for planting of Robinia pseudoacacia (1 year old with a stem diameter of less than 2.5 cm) imported from Israel, taking into account the available scientific information, including the technical information provided by Israel by 26 December 2019. The relevance of an EU-quarantine pest for this opinion was based on evidence that: (i) the pest is present in Israel; (ii) R. pseudoacacia is a host of the pest, and (iii) the pest can be associated with the commodity. The relevance of this opinion for other non EU-regulated pests was based on evidence that: (i) the pest is present in Israel (ii) the pest is absent in the EU; (iii) R.

We combine published molecular data for the chloroplast regions matK and rbcL with 66 morphological characters surveyed for 73 ingroup and two outgroup species, and use Parsimony and Bayesian approaches to explore matrices with different missing data. All combined analyses using Parsimony recovered the topology Polygalaceae (Leguminosae (Quillajaceae + Surianaceae)). Bayesian analyses with matched morphological and molecular sampling recover the same topology, but analyses based on other data recover a different Bayesian topology: ((Polygalaceae + Leguminosae) (Quillajaceae + Surianaceae)). We explore the evolution of floral characters in the context of the more consistent topology: Polygalaceae (Leguminosae (Quillajaceae + Surianaceae)). This reveals synapomorphies for (Leguminosae (Quillajaceae + Suri- anaceae)) as the presence of free filaments and marginal ⁄ ventral placentation, for (Quillajaceae + Surianaceae) as pentamery and apocarpy, and for Leguminosae the presence of an abaxial median sepal and unicarpellate gynoecium. An octamerous androecium is synapomorphic for Polygalaceae. The development of papilionate flowers, and the evolutionary context in which these phenotypes appeared in Leguminosae and Polygalaceae, shows that the morphologies are convergent rather than synapomorphic within Fabales.
