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 -
Great Trees Teacher Self-Guided Tour (SGT) Grades 4-8
Great Trees Teacher Self-Guided Tour (SGT) Grades 4-8 Welcome! This tour is designed to offer suggestions and structure to your visit. You can go in any order, and please modify and add activities to fit the needs and interests of your class. If your students get excited about a plant, a piece of sculpture, or wildlife outside of the tour – go for it! The Morris Arboretum is a wonderful place with much to see and learn! Some of the activities are easier if written out. Have students bring something to take notes on. Garden Etiquette • The most important rule is RESPECT – respect the trees and other plants, animals, and of course, people. • Students are allowed off the paths, but they should not go into mulched areas. The mulch is there to protect delicate plants and root systems. • Students MAY NOT climb trees. This damages the bark, limbs, leaves, and disturbs creatures living in the trees. • Eat and drink only in designated lunch areas. • There are bathrooms in the garden, noted on the map, as well as in the Visitor Center. • Have fun and learn about the beauty and importance of trees in our environment. Tree Identification On many of the trees, there are copper identification tags embossed with the common name of tree, the scientific name of the tree, its place of origin, and the year it was accessioned (the year it was recorded into the collection – not necessarily the year it was planted.) Find one and show students how to read them. Please DO NOT take these tags off the trees. -

Oplopanax Horridus (Smith) Miq
Oplopanax horridus (Smith) Miq. Island Hu’lqum̲ ínu’m Name(s): qwa'pulhp or qwa’pu p Upriver Halkomelem Name: qwó:pelhp English name: Devil’s club Family: Araliaceae (Ginseng family) The name Oplopanax horridus was derived from the Greek words “hoplon” meaning “weapon” and “panakos” meaning “all-heal.” Its species name refers to its formidable prickly appearance (Bressette 2017). O. horridus is in the ginseng family; “panax” is the genus name for ginseng (eflora BC 2018). Identifying characteristics: Devil’s club is a deciduous perennial shrub with an upright habit reaching an average height of 90 – 275 cm (Bressette 2017). Stems are densely packed and armed with spines that continue along leaf petioles and leaf veins. The palmate leaves are alternately arranged and very large, ranging from 20-40 cm in width, with 5-13 lobes and are sharply toothed along their margins (KPU 2015. From mid-spring to summer plants produce a large upright spike of small, light green to white florets, each with 5 petals (Summer 1998). By mid to late-summer pollinated flowers form clusters of small red drupes (KPU 2015). Distribution: Devil’s club is a native species in Canada and is found in British Columbia, Alberta (USDA 2018), and in some areas north of Lake Superior in Ontario (virtualmuseum 2005). It also occurs in the southwestern part of the Yukon Territory, and in the United States where its range extends from Alaska to Montana and as far south as Oregon (USDA 2018). Habitat: Oplopanax horridus is a shade-loving plant typically found in forest understories, especially those of old-growth forests. -
Conservation Genomics and Pollination Biology of an Endangered, Edaphic- Endemic, Octoploid Herb: El Dorado Bedstraw (Galium Californicum Subsp
Conservation genomics and pollination biology of an endangered, edaphic- endemic, octoploid herb: El Dorado bedstraw (Galium californicum subsp. sierrae; Rubiaceae) Dylan Burge Department of Ecology and Evolutionary Biology, University of California, Los Angeles, Los Angeles, CA, USA ABSTRACT El Dorado bedstraw (Galium californicum subsp. sierrae) is a federally endangered dioecious, octoploid, perennial herb found only in the Pine Hill region of El Dorado County, CA, USA. Like many species of Galium, El Dorado bedstraw is capable of both sexual and asexual reproduction, spreading via stem-layering as well as seeds. El Dorado bedstraw is also dioecious, and thus dependent on pollinators to transfer pollen from male to female stems. The capacity for asexual reproduction has conservation implications for this plant, due to the potential for populations to become dominated by a small number of clones in the absence of recruitment from seeds. No previous work has examined either the population genetics or pollination biology of this plant. Here, double-digest restriction site-associated DNA sequencing was used to develop a genetic dataset for a sample of El Dorado bedstraw (12 individuals from each of seven locations). Genomic data was used to calculate population genetic statistics and quantify the degree to which clonality affects the sampled populations. Visual observation of insect visitors at every sampling location was used to assess the potential for pollen transfer within and among Submitted 7 February 2020 locations. A total of 23 clonal colonies were detected across 82 successfully sequenced Accepted 4 September 2020 stems, consisting of an average of 2.4 individuals (range: 2–6). -

Author for correspondence (E-mail: [email protected]) Zhao, A-Man Laboratory of Systematic and Evolutionary Botany, Institute of Botany, Chinese Academy of Sciences, Beijing 100093, The People’s Republic of China. Manuscript received in april 2004 Abstract China is one of the richest countries in plant biodiversity in the world. Besides to a rich flora, which contains about 33 000 vascular plants (being 30 000 of these angiosperms, 250 gymnosperms, and 2 600 pteridophytes), there is a extraordinary ecosystem diversity. In addition, China also contains a large pool of both wild and cultivated germplasm; one of the eight original centers of crop plants in the world was located there. China is also con- sidered one of the main centers of origin and diversification for seed plants on Earth, and it is specially profuse in phylogenetically primitive taxa and/or paleoendemics due to the glaciation refuge role played by this area in the Quaternary. The collision of Indian sub- continent enriched significantly the Chinese flora and produced the formation of many neoen- demisms. However, the distribution of the flora is uneven, and some local floristic hotspots can be found across China, such as Yunnan, Sichuan and Taiwan. Unfortunately, threats to this biodiversity are huge and have increased substantially in the last 50 years. -
Non–Nest Mate Discrimination and Clonal Colony Structure in the Parthenogenetic Ant Cerapachys Biroi

One important factor is genetic relatedness, and animal societies are usually composed of related but genetically different individuals, setting the stage for conflicts over reproductive allocation. Recently, however, it has been found that several ant species reproduce predominantly asexu- ally. Although this can potentially give rise to clonal societies, in the few well-studied cases, colonies are often chimeric assemblies of different genotypes, due to worker drifting or colony fusion. In the ant Cerapachys biroi, queens are absent and all individuals reproduce via thelytokous parthenogenesis, making this species an ideal study system of asexual reproduction and its consequences for social dynamics. Here, we show that colonies in our study population on Okinawa, Japan, recognize and effectively discriminate against foreign workers, especially those from unrelated asexual lineages. In accord with this finding, colonies never contained more than a single asexual lineage and average pairwise genetic relatedness within colonies was extremely high (r = 0.99).
