												  Indoor Plants Or HouseplantsVisit us on the Web: www.gardeninghelp.org Indoor Plants or Houseplants Over the past twenty years houseplants have grown in popularity. Offered in a wide variety of sizes, shapes, colors and textures, houseplants beautify our homes and help soften our environment. They have been scientifically proven to improve our health by lowering blood pressure and removing pollutants from the air we breathe. When selecting a houseplant, choose reputable suppliers who specialize in growing houseplants. Get off to a good start by thoroughly examining each plant. Watch for brown edges and spindly growth with elongated stems and large gaps between new leaves. Inspect leaves and stem junctions for signs of insect or disease problems. Check any support stakes to make sure they are not hiding broken stems or branches. Finally, make sure the plant is placed in an area that suits its optimal requirements for light, temperature and humidity. Where to Place Your House Plants With the exception of the very darkest areas, you can always find a houseplant with growth requirements to match the environmental conditions in your home. The most important factors are light intensity and duration. The best way to determine the intensity of light at a window exposure area is to measure it with a light meter. A light meter measures light in units called foot-candles. One foot-candle is the amount of light from a candle spread over a square foot of surface area. Plants that prefer low light may produce dull, lifeless-looking leaves when exposed to bright light. Bright light can also cause leaf spots or brown-tipped scorched margins.

												  Pilea Brasiliensis: a New Species of Pilea (Urticaceae) from Central BrazilPhytotaxa 26: 17–20 (2011) ISSN 1179-3155 (print edition) www.mapress.com/phytotaxa/ Article PHYTOTAXA Copyright © 2011 Magnolia Press ISSN 1179-3163 (online edition) Pilea brasiliensis: a new species of Pilea (Urticaceae) from Central Brazil A.L. GAGLIOTI1, S. ROMANIUC1 & A.K. MONRO2 1Instituto de Botânica, CP 3005, 01031-970, São Paulo, SP, Brazil, E-mail: [email protected], [email protected] 2Departement of Botany, The Natural History Museum, London, SW75 BD, United Kingdom, E-mail:[email protected] Abstract During the course of floristic studies on Urticaceae in Distrito Federal, Brazil, we encountered a species of Pilea that was not described until now. Pilea brasiliensis is here described and illustrated, its affinities are discussed and its position in Weddell & Killip’s subdivisions of the genus is indicated. A Conservation Assessment determines P. brasiliensis to be Critically Endagered (CE) with the possibility that it may be Extinct in the Wild (EW). Key words: Critically Endangered, Elatostemateae, Fallaces, Species Conservation Assessment, systematics, taxonomy Introduction Pilea currently includes between 600–715 taxa (Adams 1970, Burger 1977, Monro 2004, 2006) and is probably the largest genus in Urticaceae. It is distributed throughout the tropics, subtropics and warm temperate regions (with the exception of Australia and New Zealand). Pilea is easily distinguished from other Neotropical Urticaceae by the combination of opposite leaves and ligulate intrapetiolar stipules in each leaf axil. Most of the species are small herbs, many of which are facultatively epiphytic or epipetric. The genus was first described by Lindley (1821), and subsequently Weddell (1869) recognized 159 species, which he classified into three groups: Integrifoliae, Heterophyllae and Dentatae, based on leaf isomorphy and margin morphology.

Received: 4 March 2020; Accepted: 19 March 2020; Published: 23 March 2020 Abstract: The process of rapid urbanization has affected the composition and diversity of urban vegetation species. The process of urbanization from 2000 was analyzed in the area of "one major city with three vice cities and six groups", according to the urban master planning of Hangzhou from 2001 to 2020. The results show that dramatic changes have occurred for land use types during the ten years from 2000 to 2010 in Hangzhou, of which urban land has become the main type of land use and the area of arable land has presented serious loss. This study found that the Gramineae and Compositae species were the main groups of ruderals in 1665 quadrats, which reflected the characteristics of a few large families. The number of Monotypic and Oligotypic family/genera accounted for 67.3% of the total number of families and 97.5% of the total number of genera.

Owen1 ABSTRACf.-A two-year field experiment was conducted to investigate factors hypothesized to affect the reproduc tive potential ofAstragalus kentrophyta var. implexus and to test the importance oftrade-offs between growth and repro duction in this species. Levels of mineral nutrients, water, herbivory, and competition were manipulated. Seed output R."1d growth of individuals in treatment groups were compared against control plants. Neither water nor mineral nutri ents alone were shown to affect growth or reproduction. Herbivory was shown to be similarly unimportant in affecting growth and reproduction. Competition with other species influenced growth but not reproduction. No significant trade offs between growth and reproduction were detected within years.

												  Landscaping with PerennialsVisit us on the Web: www.gardeninghelp.org Landscaping with Perennials The term “perennial” generally speaking, refers to a type of plant that once planted, will live for many years. This broad definition covers bulbs, woody trees and shrubs, cacti, succulents, grasses, ferns, some herbs, and many groundcovers. The popular gardening definition of a perennial, however, refers to those plants which are non-woody, have a root system that lives through the winter from which leaves emerge in the spring and die back to the ground in the fall. Plants of this type are more specifically called herbaceous perennials. The popularity of herbaceous perennials has risen in recent times because they offer a wide variety of forms and sizes, colors and textures and are relatively long-lived. Of particular significance is the fact that they generally fall into the low to moderate maintenance category which many gardeners today value due to limited resources and time. There are hundreds of perennials to choose from and they offer the gardener a good deal of versatility for all areas of the landscape. You can select plants which grow well in wet and dry sites; full sun to shade; deep, fertile to shallow, poor soils. Additionally, many will solve the problems of difficult-to-manage areas like steep embankments, hillsides and rocky sites. History of Perennials The first and most popular period for growing herbaceous perennials was in the later part of the 1800s and early 1900s. At this time, perennials were being used in Europe as border plants outlining naturalized woodland garden areas.

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 Pilea hyalina 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 “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 model1—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 our 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 any area within it.

												  THE ANDEAN SPECIES of PILEA by Ellsworth P. Killip INTRODUCTIONTHE ANDEAN SPECIES OF PILEA By Ellsworth P. Killip INTRODUCTION Pilea is by far the largest genus of Urticaceae. Weddell in his final monograph 1 of the family recognized 159 species as valid, about 50 of which were said to occur in the Andes of South America. That these species had a very limited range of distribution was indicated by the fact that more than 30 were known from only a single collection and that only 9 of the others were in any sense widely distributed in the Andean countries. Two, P. microphyUa and P. pubescens, occurred throughout the American Tropics, and P. kyalina and P. dendrophUa extended eastward in South America. In the 50 years following the publication of this monograph only 10 species were described from the Andean region. Because of the large number of specimens of Pilea collected by expeditions to the Andes sponsored by the Smithsonian Institution, the New York Botanical Garden, the Gray Herbarium and the Arnold Arboretum of Harvard University, the Field Museum of Natural History, and the Academy of Natural Sciences, Philadelphia, which were submitted to me for identification but which could not be assigned to any known species, I began the preparation of a mono- graph of all the Andean species. This was completed in 1935 but unfortunately could not be printed in its entirety at that time. Instead, a greatly abridged paper was published,2 which contained a key to all the Andean species, descriptions of 30 new ones, and a few changes of name and of rank. In this there was no opportunity to present descriptions of the earlier species or to discuss their synonymy.
