Weed Risk Assessment for Iris Pseudacorus L. (Iridaceae)
Weed Risk Assessment for Iris United States pseudacorus L.

Agency Contact: Plant Epidemiology and Risk Analysis Laboratory Center for Plant Health Science and Technology Plant Protection and Quarantine Animal and Plant Health Inspection Service United States Department of Agriculture 1730 Varsity Drive, Suite 300 Raleigh, NC 27606 Weed Risk Assessment for Iris pseudacorus Introduction Plant Protection and Quarantine (PPQ) regulates noxious weeds under the authority of the Plant Protection Act (7 U.S.C. § 7701-7786, 2000) and the Federal Seed Act (7 U.S.C. § 1581-1610, 1939). A noxious weed is defined as “any plant or plant product that can directly or indirectly injure or cause damage to crops (including nursery stock or plant products), livestock, poultry, or other interests of agriculture, irrigation, navigation, the natural resources of the United States, the public health, or the environment” (7 U.S.C. § 7701-7786, 2000). We use weed risk assessment (WRA)— specifically, the PPQ WRA model (Koop et al., 2012)—to evaluate the risk potential of plants, including those newly detected in the United States, those proposed for import, and those emerging as weeds elsewhere in the world. Because the PPQ WRA model is geographically and climatically neutral, it can be used to evaluate the baseline invasive/weed potential of any plant species for the entire United States or for any area within it. As part of this analysis, we use a stochastic simulation to evaluate how much the uncertainty associated with the analysis affects the model outcomes. -

Loomans KEY WORDS First record, introduction, invasive species, minor pest, risks Entomologische Berichten 76 (3): 103-108 Thrips setosus Moulton, the Japanese flower thrips, has been found for the first time in the Netherlands. On September 30 2014, 22 females and 5 larvae of this species were detected on Hydrangea in a nursery at Kudelstaart. Until then, T. setosus had only been known from Japan and South Korea, where it is a polyphagous minor pest and with no known association with Hydrangea. Remarkably, interceptions in the international trade of plant products of this opportunistic species are very scarce, and this thrips has not been recorded as an invasive species. A survey carried out showed its presence in several Hydrangea nurseries in the Netherlands. However, the origin of the populations and the year of introduction into the country could not be established. Based on a short risk analysis it has been decided not to focus on elimination of the species, but to inform national and international organizations involved in plant protection about its occurrence. Details about its detection and identification, and the results of the survey, are presented. Introduction For diagnostic purposes he sent this material together with site Thrips (Thysanoptera) are known as plant pests worldwide, information to the National Reference Centre of the NVWA. especially in ornamentals and vegetables.

WILSON Rancho Santa Ana Botanic Garden, 1500 North College Avenue, Claremont, California 91711-3157, USA (carol. wilson@ cgu. edu) ABSTRACT Subgeneric groups have been circumscribed in Iris based on a small number of morphological characters. Recent DNA sequence data has indicated that several of the subgenera, sections, and series that have previously been delineated are paraphyletic or polyphyletic. The evolution of characters that have traditionally been used to distinguish sub generic and sectional groups within Iris was investigated by mapping these characters on a phylogenetic tree based on matK sequence data. Results indicate that rhizomes are pleisomorphic for the genus and that three bulb types have arisen independently. My analysis shows that sepal beards, sepal crests, and seed arils show extensive homoplasy. Most of the homoplasy seen is associated with the circumscription of polyphyletic subgeneric groups such as the beardless subgenus Limniris. Some additional homoplasy is due to diversity within supported clades or the historical use of a single character in circumscribing more than one subgeneric group. -

TREWICK defining feature of the Hexapoda, as the name suggests, is six legs. Also, the body comprises a head, thorax, and abdomen. The number A of abdominal segments varies, however; there are only six in the Collembola (springtails), 9–12 in the Protura, and 10 in the Diplura, whereas in all other hexapods there are strictly 11. Insects are now regarded as comprising only those hexapods with 11 abdominal segments. Whereas crustaceans are the dominant group of arthropods in the sea, hexapods prevail on land, in numbers and biomass. Altogether, the Hexapoda constitutes the most diverse group of animals – the estimated number of described species worldwide is just over 900,000, with the beetles (order Coleoptera) comprising more than a third of these. Today, the Hexapoda is considered to contain four classes – the Insecta, and the Protura, Collembola, and Diplura. The latter three classes were formerly allied with the insect orders Archaeognatha (jumping bristletails) and Thysanura (silverfish) as the insect subclass Apterygota (‘wingless’). The Apterygota is now regarded as an artificial assemblage (Bitsch & Bitsch 2000). -
Iris Sibirica and Others Iris Albicans Known As Cemetery
Iris Sibirica and others Iris Albicans Known as Cemetery Iris as is planted on Muslim cemeteries. Two different species use this name; the commoner is just a white form of Iris germanica, widespread in the Mediterranean. This is widely available in the horticultural trade under the name of albicans, but it is not true to name. True Iris albicans which we are offering here occurs only in Arabia and Yemen. It is some 60cm tall, with greyish leaves and one to three, strongly and sweetly scented, 9cm flowers. The petals are pure, bone- white. The bracts are pale green. (The commoner interloper is found across the Mediterranean basin and is not entitled to the name, which continues in use however. The wrongly named albicans, has brown, papery bracts, and off-white flowers). Our stock was first found near Sana’a, Yemen and is thriving here, outside, in a sunny, raised bed. Iris Sibirica and others Iris chrysographes Black Form Clumps of narrow, iris-like foliage. Tall sprays of darkest violet to almost black velvety flowers, Jun-Sept. Ht 40cm. Moist, well drained soil.

Your Beautiful Flower Garden
Chapter Three Your Beautiful Flower Garden Introduction Whether it’s one planter next to your door, or a show-stopping floral garden, flowers are a bonus of color and texture we can all appreciate. If you’re an experienced green thumb, or have read up on basic gardening in Chapter Two, you’ll know that, rather than insects and diseases, most plant problems are cultural—meaning that if you give plants what they need (proper soil, location and care), they’ll be healthy most of the time. Keep an eye on your garden. Noticing problems and identifying them early are essential steps toward a satisfying result. What follows are common cultural, disease, and insect problems, and their solutions. That’s a lot to cover. We’ll start with general concerns, then focus on specifics for annuals, tender perennials, biennials, and perennials. (Don’t worry if you see a plant in both the Perennial and Annual charts. Some, like verbena and geranium, can be perennial in warmer climates.) Later we’ll discuss hostas, roses, bulbs and peonies. Photo: Pixabay. Perennial, biennial, or annual? Perennials tend to come back In this chapter: over repeated years and expand each season. They may live three or four years, thirty or a hundred.

New Perspectives on Medicinal Properties and Uses of Iris Sp
Hop and Medicinal Plants, Year XXIV, No. 1-2, 2016 ISSN 2360 – 0179 print, ISSN 2360 – 0187 electronic NEW PERSPECTIVES ON MEDICINAL PROPERTIES AND USES OF IRIS SP. CRIŞAN Ioana, Maria CANTOR* Faculty of Horticulture, University of Agricultural Sciences and Veterinary Medicine, Manastur Street 3-5, 400372 Cluj-Napoca, Romania *corresponding author: [email protected] Abstract. Rhizomes from various Iris species have been used in traditional medicine to treat a variety of ailments since ancient times and many constituents isolated from different Iris species demonstrated potent biological activities in recent studies. All research findings besides the increasing demand for natural ingredients in cosmetics and market demand from industries like alcoholic beverages, cuisine and perfumery indicate a promising future for cultivation of irises for rhizomes, various extracts but most importantly for high quality orris butter. Romania is situated in a transitional continental climate with suitable conditions for hardy iris species and thus with good prospects for successful cultivation of Iris germanica, Iris florentina and Iris pallida in conditions of economic efficiency. Key words: Iris, medicinal plant, orris butter, rhizomes Introduction The common word “iris” that gave the name of the genus, originates from Greek designating “rainbow” presumably due to the wide variety of colors that these flowers can have (Cumo, 2013). The genus reunites about 300 species (Wang et al., 2010) with rhizomes or bulbs (Cantor, 2016). In Romanian wild flora can be met both naturalized and native species, some enjoying special protection, like Iris aphylla ssp. hungarica (Marinescu and Alexiu, 2013) that can be seen on the hills nearby Cluj-Napoca (Fig. -
