To remedy this, we sequenced small RNAs from vegetative and dissected 5 inflorescence tissue in 28 phylogenetically diverse monocots and from several early‐diverging 6 angiosperm lineages, as well as publicly available data from 10 additional monocot species. -
Low Risk Aquarium and Pond Plants
Plant Identification Guide Low-risk aquarium and pond plants Planting these in your pond or aquarium is environmentally-friendly. Glossostigma elatinoides, image © Sonia Frimmel. One of the biggest threats to New Zealand’s waterbodies is the establishment and proliferation of weeds. The majority of New Zealand’s current aquatic weeds started out as aquarium and pond plants. To reduce the occurrence of new weeds becoming established in waterbodies this guide has been prepared to encourage the use of aquarium and pond plants that pose minimal risk to waterbodies. Guide prepared by Dr John Clayton, Paula Reeves, Paul Champion and Tracey Edwards, National Centre of Aquatic Biodiversity and Biosecurity, NIWA with funding from the Department of Conservation. The guides will be updated on a regular basis and will be available on the NIWA website: www.niwa.co.nz/ncabb/tools. Key to plant life-forms Sprawling marginal plants. Grow across the ground and out over water. Pond plants Short turf-like plants. Grow in shallow water on the edges of ponds and foreground of aquariums. Includes very small plants (up to 2-3 cm in height). Most species can grow both submerged (usually more erect) and emergent. Pond and aquarium plants Tall emergent plants. Can grow in water depths up to 2 m deep depending on the species. Usually tall reed-like plants but sometimes with broad leaves. Ideal for deeper ponds. Pond plants Free floating plants. These plants grow on the water surface and are not anchored to banks or bottom substrates. Pond and aquarium plants Floating-leaved plants. Water lily-type plants. -

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 Echinodorus uruguayensis 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. -

Weeds of the future? Threats to Australia’s grazing industries by garden plants Abstract This report identifies 281 introduced garden plants and 800 lower priority species that present a significant risk to Australia’s grazing industries should they naturalise. Of the 281 species: • Nearly all have been recorded overseas as agricultural or environmental weeds (or both); • More than one tenth (11%) have been recorded as noxious weeds overseas; • At least one third (33%) are toxic and may harm or even kill livestock; • Almost all have been commercially available in Australia in the last 20 years; • Over two thirds (70%) were still available from Australian nurseries in 2004; • Over two thirds (72%) are not currently recognised as weeds under either State or Commonwealth legislation. -

This has also reportedly affected the payments from China to our exporters. The shortage of containers adds to the worries of the exporters to ship out seafood cargo from India to different destinations anticipating New Year demand. The General Administration and Customs China (GACC) has demanded a virtual inspection of two seafood processing units in India during the month and accordingly, two units were presented for virtual inspection by the end of the month to GACC on their preparedness on food safety, especially in tackling the Covid-19 contamination through seafood cargo. -

Acta Rer. Natur. Mus. Nat. Slov. Vol. LXIII Bratislava, 2017 NOTES ON SOME RATAJ’S NAMES IN THE GENUS ECHINODORUS (ALISMATACEAE) Jozef Somogyi Abstract: Notes on the nomenclature and taxonomy of some taxa of the genus Echinodorus described by Karel Rataj (1925–2014) are given. Many of them have lacked a type specimen and their supposed types have never been deposited in the herbarium PR, even if that was so stated in the protologues. Unfortunately, as the types are cited in the protologues, the names have to be treated as valid according to the Code. The specimens labelled as “holotypes” of the names E. africanus, E. gabrielii, E. janii, E. pseudohorizontalis, E. schlueteri, E. veronikae and E. viridis appeared in the herbarium PR only lately. However, none of these specimens can be considered as a holotype. The true holotypes of E. africanus and E. schlueteri have already existed before. The names E. gabrielii, E. heikobleheri, E. opacus, E. osiris, E. pseudohorizontalis and E. viridis are typified here. It is impossible to typify the names E. janii, E. multiflorus and E. veronikae. One previously published information on E. densinervis is corrected in the appendix of this article. Key words: Echinodorus, typification, nomenclature, taxonomy, Karel Rataj Abstrakt: Poznámky k niektorým Ratajovým menám v rode Echinodorus (Alismataceae). Mnohým druhom rodu Echinodorus, ktoré opísal Karel Rataj (1925 – 2014), chýbajú typové herbárové položky, aj keď v protológoch je uvedené, že boli deponované v herbári PR. Žiaľ, keďže tieto neexistujúce typy sú citované v protológoch, je nutné takto publikované mená považovať za platné v zmysle Kódu. -

(1971): The taxonomy of Echinodorus palaefolius (NEES et MART.), MACBR. (Alismataceae) and related species from Mexico, Central and South America. - Preslia, .Praha, 43 : 10- 16. - The paper deals with the taxonomy of 4 related species of t.he genus Echinodorus [E. palaefolius (NEES et MART.) MACBR., E. andrieuxii (HooK. et ARN.) SMALL, E. pubescens (MART.) SEUBERT and E. subulatus (MART.) GRISEB.] whose elaboration b y former authors was unclear. A common character of these species are 12 stamens in the flowers, nutlets having only one gland and a very long beak. The following new nomenclatural combinations have been proposed: E. palaefolius var. latifolius (Mwn.) RATAJ, E . palaefolius var. minus (SEUBERT) RATAJ and E. andrieuxii var. longistyl·is (Buen.) RATAJ. Introduction Echinodorus palaefolius (NEES et MART.) MACBR. and the related species belong to the least perfectly worked out taxa of this genus. MICHELI (1881) quotes this species under the name E. ellipticus (MART.) MrcH., while he takes the name Sagittaria palaefolia NEES et MART. 1823 for a synonym, although it is older than Alisma ellipticum MART. 1830. MICHELI (1881) distinguished four varieties: rx latifolia ( = Al,isma ellip ticum MART.); ~ pubescens ( = Alisma pubescens MART.) ; y ovata ( = Alisma andrieuxii HooK. et ARN.) and 3 minor ( = Alisma ellipticitm MART. -
