306 Cytologia 21 Cytological Studies in l-lelobiae, I. Chromosome idiograms and a list of chromosome numbers in seven families1 Ititaro Harada Biological Institute, Faculty of Science, Nagoya University, Nagoya Received Decemnber 27, 1955 Introduction As a part of the cooperative work on the karyotypic investigations of monocotyledonous plants, directed by Dr. Y. Sinoto, the writer has been studying the Order Helobiae since 1940. The writer will report the cytologi cal evidences, principally the karyotypic analyses in seven families of Helobiae. The Order Helobiae, otherwise called Helobiales, Fluviales or Najadales, is a unique group in Angiosperms, growing in aquatic habitat. Further, from several points of view, Helobiae is regarded as a systematically or phylogenetically important group. It is said that Helobiae is an ecological group involving those plants growing in fresh water or marsh and in sea or brackish water. "Sea grasses ", the submarine phanerogamous plants, are found solely in Helobiae. Growing surroundings of each genus are as follows2: 1. Potamogetonaceae emerg. flow. and some species with (Althenia) brackish water, submerged fl oat. leav. (Cynzodocea) sea water, submarine 4. Scheuchzeriaceae (Diplanthera) sea wat., submar.

So far, however, the writer has detected nothing tangible about it, especially about a plausible relationship between the aquatic habitat and the karyotypic characteristics. But some of the submerged limnetic species and, as far as studied, all species of submarine sea grasses exhibit respectively the characteristic pollen form and the polli Figs. 36-44.

Harada Cytologia 21 nation pattern, revealing an elaborate adaptation to the aquatic surroundings. For long it has been said by several botanists that Helobiae was a group having the phylogenetically most primitive type in Monocotyledons and could be regarded as a stock in the phylogenetical development of Monocotyledons. Moreover, many botanists have assumed that HeIohiae was standing in a joint Figs. 42-47. 42, N. oguraensis (RT). 43, N. tenuicaulis (RT): a (•Š), b (_??_). 44, N. sp. 45, Aponogeton distachyus, ca. •~2200. a (RT), b (PMC-I), c (PG-I). 46 and 47, Scheu chzeriaceae. ca. •~2200. 46, Scheaehzeria palustris (RT). 47, Triglochin maritimum: a and b (RT), c (PMC-I). ing point between Dicotyledons and Monocotyledons; especially a phylogenetical relationship between Ranales and Helobiae has been often discussed. The first cytological work on this problem was published by Liehr (1916). With the same idea, principally from the karyotypic standpoint , the present writer studied the chromosome number of some water plants in Ranales and of 1956 CytologicalStudies in Helobiae, I. 311 other dicotyledonous water plants (Harada 1952). Further, for a contribution to the cyto-phylogenetical relationship of Helobiae, the writer studied the chromosome number of Pandanales (Harada 1949 a), which is systematically arranged in closer rank to Helobiae in Engler's system and is also regarded as one of the more primitive groups in Monocotyledons.

To access permit conditions, click here. Never purchase living specimens without having a disposition strategy in place. The USDA does not require any special permits to ship and/or receive Elodea except in Puerto Rico, where shipment of aquatic plants is prohibited. However, in order to continue to protect our environment, you must house your Elodea in an aquarium. Under no circumstances should you release your Elodea into the wild. Primary Hazard Considerations Always wash your hands thoroughly before and after you handle your Elodea, or anything it has touched. Availability Elodea is available year round. Elodea should arrive with a green color, it should not be yellow or “slimy.” • Elodea canadensis—Usually bright green with three leaves that form whorls around the stem. The whorls compact as they get closer to the tip. Found completely submerged. Is generally a thinner species of Elodea. Has a degree of seasonality May–June. • Egeria densa—Usually bright green with small strap-shaped leaves with fine saw teeth. 3–6 leaves form whorls around the stem and compact as they get closer to the tip. Usually can grow to be a foot or two long. Is thicker and bushier than E. canadensis. Elodea arrives in a sealed plastic bag. Upon arrival, this should be opened and Elodea should be kept moist, or it should be placed in a habitat. For short term storage (1–2 weeks), Elodea should be placed in its bag into the refriger- ator (4 °C).

    Status and Strategy for Flowering Rush (Butomus Umbellatus L.) Management

    State of Michigan’s Status and Strategy for Flowering Rush (Butomus umbellatus L.) Management Scope Invasive flowering rush (Butomus umbellatus L., hereafter FR) has invaded the shores of Michigan waterways since the early 1900’s (Core 1941; Stuckey 1968; Anderson et al. 1974). This document was developed by Central Michigan University and reviewed by Michigan Departments of Environmental Quality and Natural Resources for the purposes of: • Summarizing the current level of understanding on the biology and ecology of FR. • Summarizing current management options for FR in Michigan. • Identifying possible future directions of FR management in Michigan. This document used the current information available in journals, publications, presentations, and experiences of leading researchers and managers to meet its goals. Any chemical, company, or organization that is mentioned was included for its involvement in published, presented, or publically shared information, not to imply endorsement of the chemical, company, or organization. Biology and Ecology I. Identification Flowering rush is an emergent aquatic perennial plant with linear, sword-like leaves, triangular in cross-section, and a showy umble of pink flowers (Figure 1). Rhizomes (i.e. horizonal root-like stems) are fleshy, and leaves have parallel veination and can be submersed or emergent. Submersed leaves are linear and limp, unlike sword-like emergent leaves. Flowering rush blooms from June to August. Flowers are arranged in terminal umbels. Flower parts are found in multiples of three (e.g. six tepals, nine stamen, six carpels) with pink to purple tepals 0.25 – 0.5 in (6 - 11.5 mm) long (eFloras 2008). Each flower produces up to six beaked fruits.

    55 (4) • November 2006: 837–856 Qiu & al. • Basal angiosperm phylogeny Reconstructing the basal angiosperm phylogeny: evaluating information content of mitochondrial genes Yin-Long Qiu1, Libo Li, Tory A. Hendry, Ruiqi Li, David W. Taylor, Michael J. Issa, Alexander J. Ronen, Mona L. Vekaria & Adam M. White 1Department of Ecology & Evolutionary Biology, The University Herbarium, University of Michigan, Ann Arbor, Michigan 48109-1048, U.S.A. [email protected] (author for correspondence). Three mitochondrial (atp1, matR, nad5), four chloroplast (atpB, matK, rbcL, rpoC2), and one nuclear (18S) genes from 162 seed plants, representing all major lineages of gymnosperms and angiosperms, were analyzed together in a supermatrix or in various partitions using likelihood and parsimony methods. The results show that Amborella + Nymphaeales together constitute the first diverging lineage of angiosperms, and that the topology of Amborella alone being sister to all other angiosperms likely represents a local long branch attrac- tion artifact. The monophyly of magnoliids, as well as sister relationships between Magnoliales and Laurales, and between Canellales and Piperales, are all strongly supported. The sister relationship to eudicots of Ceratophyllum is not strongly supported by this study; instead a placement of the genus with Chloranthaceae receives moderate support in the mitochondrial gene analyses. Relationships among magnoliids, monocots, and eudicots remain unresolved. Direct comparisons of analytic results from several data partitions with or without RNA editing sites show that in multigene analyses, RNA editing has no effect on well supported rela- tionships, but minor effect on weakly supported ones. Finally, comparisons of results from separate analyses of mitochondrial and chloroplast genes demonstrate that mitochondrial genes, with overall slower rates of sub- stitution than chloroplast genes, are informative phylogenetic markers, and are particularly suitable for resolv- ing deep relationships.

    Sagittaria Policy

    Declared Plant Policy This policy relates to natural resources management under section 9(1)(d) of the Landscape South Australia Act 2019 (the Act), enabling co-ordinated implementation and promotion of sound management programs and practices for the use, development or protection of natural resources of the State. Specifically, this policy provides guidance on the use and management of natural resources relating to the prevention or control of impacts caused by pest species of plants that may have an adverse effect on the environment, primary production or the community, as per object s7(1)(f) of the Act. sagittaria (Sagittaria platyphylla) Sagittaria is an emergent aquatic plant that is rare in South Australia. In the eastern States it is a problem weed that obstructs drains and irrigation channels. It resembles giant arrowhead, Sagittaria montevidensis, which is not known in South Australia, but is established in New South Wales and Victoria, and is the subject of a separate policy. Management Plan for Sagittaria Outcomes • Maintain waterways free of blockages by water weeds. • Maintain wetlands free of major weed threats. Objectives • Eradicate current infestations on the Murray and in dams in the Mount Lofty ranges • Prevent further introduction of sagittaria to waterways and wetlands. Best Practice Implementation • Any infestations of sagittaria discovered to be treated as incursions and destroyed. • To prevent introduction or spread, any sale and movement to be prohibited. • Regional landscape boards and Green Adelaide to inspect
