Aroids range from tiny floating aquatic plants to forest climbers. Many are cultivated for their ornamental flowers or foliage and others for their food value. Present article critically reviews the growth conditions of Epipremnum aureum (Linden and Andre) Bunting with special emphasis on their ethnomedicinal uses and pharmacological activities, beneficial to both human and the environment. In this article, we review the origin, distribution, brief morphological characters, medicinal and pharmacological properties of Epipremnum aureum, commonly known as ornamental plant having indoor air pollution removing capacity. There are very few reports to the medicinal properties of E. aureum. In our investigation, it has been found that each part of this plant possesses antibacterial, anti-termite and antioxidant properties. However, apart from these it can also turn out to be anti-malarial, anti- cancerous, anti-tuberculosis, anti-arthritis and wound healing etc which are a severe international problem. In the present study, details about the pharmacological actions of medicinal plant E. aureum (Linden and Andre) Bunting and Epipremnum pinnatum (L.) Engl.

  • "National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary."
    Intro 1996 National List of Vascular Plant Species That Occur in Wetlands The Fish and Wildlife Service has prepared a National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary (1996 National List). The 1996 National List is a draft revision of the National List of Plant Species That Occur in Wetlands: 1988 National Summary (Reed 1988) (1988 National List). The 1996 National List is provided to encourage additional public review and comments on the draft regional wetland indicator assignments. The 1996 National List reflects a significant amount of new information that has become available since 1988 on the wetland affinity of vascular plants. This new information has resulted from the extensive use of the 1988 National List in the field by individuals involved in wetland and other resource inventories, wetland identification and delineation, and wetland research. Interim Regional Interagency Review Panel (Regional Panel) changes in indicator status as well as additions and deletions to the 1988 National List were documented in Regional supplements. The National List was originally developed as an appendix to the Classification of Wetlands and Deepwater Habitats of the United States (Cowardin et al.1979) to aid in the consistent application of this classification system for wetlands in the field.. The 1996 National List also was developed to aid in determining the presence of hydrophytic vegetation in the Clean Water Act Section 404 wetland regulatory program and in the implementation of the swampbuster provisions of the Food Security Act. While not required by law or regulation, the Fish and Wildlife Service is making the 1996 National List available for review and comment.

Biodiversitas 19: 140-152. Bogor Botanic Gardens is an ex-situ conservation centre, covering an area of 87 ha, with 12,376 plant specimens, collected from Indonesia and other tropical countries throughout the world. One of the richest collections in the Gardens comprises members of the aroid family (Araceae). The aroids are planted in several garden beds as well as in the nursery. They have been collected from the time of the Dutch era until now. These collections were obtained from botanical explorations throughout the forests of Indonesia and through seed exchange with botanic gardens around the world. Several of the Bogor aroid collections represent ‘living types’, such as Scindapsus splendidus Alderw., Scindapsus mamilliferus Alderw. and Epipremnum falcifolium Engl. These have survived in the garden from the time of their collection up until the present day. There are many aroid collections in the Gardens that have potentialities not widely recognised. The aim of this study is to reveal the diversity of aroids species in the Bogor Botanic Gardens, their scientific value, their conservation status, and their potential as ornamental plants, medicinal plants and food.

A full description of R. tenuis is presented together with a modification to the most recent published key to Rhaphidophora in Borneo and photographs. This reinstatement takes to 5 the number of Rhaphidophora species recognized for Borneo. Introduction In the revision of Rhaphidophora for Borneo Boyce (200) treated Rhaphidophora korthalsii Hassk. as a polymorphic species. Since that publication, the author has been able to undertake extended and on-going fieldwork in Sarawak which has revealed that at least one element of Bornean R. korthalsii sensu Boyce 200 is a morphologically stable taxon with a suite of characters consistently separating it from R. korthalsii s. s. In particular the smaller stature, slender leaflets and solitary, slender inflorescence, and most strikingly in the form of the leaves in the juvenile shingling plant which are ovate and spreading in R. korthalsii s. s.

  • 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.

  • Leaf Variegation in Caladium Steudneriifolium (Araceae): a Case of Mimicry?
    Evol Ecol (2009) 23:503–512 DOI 10.1007/s10682-008-9248-2 ORIGINAL PAPER Leaf variegation in Caladium steudneriifolium (Araceae): a case of mimicry? Ulf Soltau Æ Stefan Do¨tterl Æ Sigrid Liede-Schumann Received: 27 November 2007 / Accepted: 25 February 2008 / Published online: 6 March 2008 Ó Springer Science+Business Media B.V. 2008 Abstract The leaves of Caladium steudneriifolium (Araceae) of the understorey of a submontane rainforest in the Podocarpus National Park (South East Ecuador, 1,060 m a.s.l.) are plain green or patterned with whitish variegation. Of the 3,413 individual leaves randomly chosen and examined in April 2003, two-thirds were plain green, whereas one third were variegated (i.e., whitish due to absence of chloroplasts). Leaves of both morphs are frequently attacked by mining moth caterpillars. Our BLAST analysis based on Cytochrome-c-Oxidase-subunit-1 sequences suggests that the moth is possibly a member of the Pyraloidea or another microlepidopteran group. It was observed that the variegated leaf zones strongly resemble recent damages caused by mining larvae and therefore may mimic an attack by moth larvae. Infestation was significantly 4–12 times higher for green leaves than for variegated leaves. To test the hypothesis that variegation can be interpreted as mimicry to deter ovipositing moths, we first ruled out the possibility that variegation is a function of canopy density (i.e., that the moths might be attracted or deterred by factors unrelated to the plant). Then plain green leaves were artificially variegated and the number of mining larvae counted after 3 months.

  • The Evolution of Pollinator–Plant Interaction Types in the Araceae
    BRIEF COMMUNICATION doi:10.1111/evo.12318 THE EVOLUTION OF POLLINATOR–PLANT INTERACTION TYPES IN THE ARACEAE Marion Chartier,1,2 Marc Gibernau,3 and Susanne S. Renner4 1Department of Structural and Functional Botany, University of Vienna, 1030 Vienna, Austria 2E-mail: [email protected] 3Centre National de Recherche Scientifique, Ecologie des Foretsˆ de Guyane, 97379 Kourou, France 4Department of Biology, University of Munich, 80638 Munich, Germany Received August 6, 2013 Accepted November 17, 2013 Most plant–pollinator interactions are mutualistic, involving rewards provided by flowers or inflorescences to pollinators. An- tagonistic plant–pollinator interactions, in which flowers offer no rewards, are rare and concentrated in a few families including Araceae. In the latter, they involve trapping of pollinators, which are released loaded with pollen but unrewarded. To understand the evolution of such systems, we compiled data on the pollinators and types of interactions, and coded 21 characters, including interaction type, pollinator order, and 19 floral traits. A phylogenetic framework comes from a matrix of plastid and new nuclear DNA sequences for 135 species from 119 genera (5342 nucleotides). The ancestral pollination interaction in Araceae was recon- structed as probably rewarding albeit with low confidence because information is available for only 56 of the 120–130 genera. Bayesian stochastic trait mapping showed that spadix zonation, presence of an appendix, and flower sexuality were correlated with pollination interaction type. In the Araceae, having unisexual flowers appears to have provided the morphological precon- dition for the evolution of traps. Compared with the frequency of shifts between deceptive and rewarding pollination systems in orchids, our results indicate less lability in the Araceae, probably because of morphologically and sexually more specialized inflorescences.

  • The Genus Amorphophallus
    The Genus Amorphophallus (Titan Arums) Origin, Habit and General Information The genus Amorphophallus is well known for the famous Amorphophallus titanum , commonly known as "Titan Arum". The Titan Arum holds the plant world record for an unbranched single inflorescence. The infloresence eventually may reach up to three meters and more in height. Besides this oustanding species more than 200 Amorphophallus species have been described - and each year some more new findings are published. A more or less complete list of all validly described Amorphophallus species and many photos are available from the website of the International Aroid Society (http://www.aroid.org) . If you are interested in this fascinating genus, think about becoming a member of the International Aroid Society! The International Aroid Society is the worldwide leading society in aroids and offers a membership at a very low price and with many benefits! A different website for those interested in Amorphophallus hybrids is: www.amorphophallus-network.org This page features some awe-inspiring new hybrids, e.g. Amorphophallus 'John Tan' - an unique and first time ever cross between Amorphophallus variabilis X Amorphophallus titanum ! The majority of Amorphophallus species is native to subtropical and tropical lowlands of forest margins and open, disturbed spots in woods throughout Asia. Few species are found in Africa (e.g. Amorphophallus abyssinicus , from West to East Africa), Australia (represented by a single species only, namely Amorphophallus galbra , occuring in Queensland, North Australia and Papua New Guinea), and Polynesia respectively. Few species, such as Amorphophallus paeoniifolius (Madagascar to Polynesia), serve as a food source throughout the Asian region.
