Where All of the Undescribed Fungi?Г Wherein Only 7% of the Worldгs

Fungi also comprise about 95% of all known plant pathogens, the remainder being bacteria, mycoplasma-like organisms and viruses (Shivas and Hyde, 1997). Rossman et al. (1987), from Literature Guide for the Identification of Plant Pathogenic Fungi, estimated the number of plant pathogenic fungi about 23,000, however, their estimation includes only those species that cause disease in vascular plants. In tropical area, moreover, Shivas and Hyde (1997) estimated about 270,000 of plant pathogenic fungi may present based on four parameters: (1) three-quarters of plant genera known occur in the tropics, (2) plant genera have an average about 50 fungal pathogens, (3) one-half of the pathogens on a host are specific to the host genus or to closely related genera and (4) few fungal pathogens have a wide host range. Although there were wide variations about the estimation of fungi including plant pathogenic fungi occur worldwide, tropical regions were generally assumed to host the greatest diversity of life and plant pathogens. It does not take into account epiphytic, lichen forming, lichenicolous mycoparasitic and mycorrhiza. Ironically, high population and rapid industrialization in most of the tropical countries present serious habitat destruction and environmental issues include large- 2 scale illegal deforestation, over-exploitation of marine resources and other environmental problems of which finally threatens the survival of indigenous and endemic species, including fungi. -
1 Ornamental Palms
1 Ornamental Palms: Biology and Horticulture T.K. Broschat and M.L. Elliott Fort Lauderdale Research and Education Center University of Florida, Davie, FL 33314, USA D.R. Hodel University of California Cooperative Extension Alhambra, CA 91801, USA ABSTRACT Ornamental palms are important components of tropical, subtropical, and even warm temperate climate landscapes. In colder climates, they are important interiorscape plants and are often a focal point in malls, businesses, and other public areas. As arborescent monocots, palms have a unique morphology and this greatly influences their cultural requirements. Ornamental palms are over- whelmingly seed propagated, with seeds of most species germinating slowly and being intolerant of prolonged storage or cold temperatures. They generally do not have dormancy requirements, but do require high temperatures (30–35°C) for optimum germination. Palms are usually grown in containers prior to trans- planting into a field nursery or landscape. Because of their adventitious root system, large field-grown specimen palms can easily be transplanted. In the landscape, palm health and quality are greatly affected by nutritional deficien- cies, which can reduce their aesthetic value, growth rate, or even cause death. Palm life canCOPYRIGHTED also be shortened by a number of MATERIAL diseases or insect pests, some of which are lethal, have no controls, or have wide host ranges. With the increasing use of palms in the landscape, pathogens and insect pests have moved with the Horticultural Reviews, Volume 42, First Edition. Edited by Jules Janick. 2014 Wiley-Blackwell.

Starchy Pollen in Commelinoid Monocots
Annals of Botany 87: 109±116, 2001 doi:10.1006/anbo.2000.1310, available online at http://www.idealibrary.com on Starchy Pollen in Commelinoid Monocots SCOTT ZONA Fairchild Tropical Garden, 11935 Old Cutler Road, Coral Gables, Miami, FL 33156 USA* and Department of Biological Sciences, Florida International University, Miami, FL 33199 USA Received: 12 July 2000 Returned for revision: 7 September 2000 Accepted: 27 September 2000 Published electronically: 20 November 2000 The Commelinoid monocots are a monophyletic group comprising the Arecales, Commelinales, Poales and Zingiberales, plus the unplaced family Dasypogonaceae. Pollen from 149 taxa was examined qualitatively for starch as the primary storage product. Starchy pollen was found in 134 taxa (90 % of the sample) of Commelinoid monocots. Starchy pollen thus appears be a characteristic feature of the Commelinoid monocots. Starchy pollen can be easily observed with minimal preparation, making it a demonstrable character useful in the classroom or teaching laboratory. Furthermore, starchy pollen grains were found to be signi®cantly larger in diameter than non-starchy grains, con®rming previous hypotheses regarding pollen size and starch. # 2000 Annals of Botany Company Key words: Arecales, Commelinales, Commelinoid monocots, Monocotyledonae, Poales, pollen, starch, Zingiberales.

John C. Gifford Arboretum Catalog of Plants
John C. Gifford Arboretum Catalog of Plants University of Miami DĂƌĐŚ, 201ϴ Table of Contents Introduction Brief History of the Arboretum How to Use this Catalog Map of the Gifford Arboretum Exhibit 1 - The Arecaceae (Palms) Exhibit 2 – Euphorbiaceae and Other Malpighiales Exhibit 3 – The Gymnosperms (Naked-seed Plants) Exhibit 4 – Moraceae and Other Rosales Exhibit 5 – Sapotaceae and Other Ericales Exhibit 6 – The Fabaceae Exhibit 7 – The Bignoniaceae Exhibit 8 – The Myrtales Exhibit 9 – Basal Angiosperms (Primitive Flowering Plants) Exhibit 10 - The Sapindales Exhibit 11 – The Malvales Exhibit 12 – South Florida Natives Exhibit 13 – What is a Tree? Exhibit 14 – Maya Cocoa Garden Introduction This new Catalog of the trees and plants of the Gifford Arboretum has been in the works for over years. It has been a labor of love, but also much more difficult than anticipated. Part of the difficulty has been taxonomic upheaval as genetic analysis has reordered the taxonomy of many plant species. However, that also makes the catalog all the more timely and needed. It includes plot maps and cross references to hopefully increase its value to users, and it has been paired with the creation and installation of new identification tags that include QR codes for all plants in the Arboretum. These codes allow guests to learn about WKH plants right as they stroll through the Arboretum. QR reader apps are free andHDV\ WR download WR D smart phone, DQGWKH\ greatly increase the educational value of the Arboretum to you Special thanks are due to WKRVH who worked on the new Catalog, including Aldridge Curators Anuradha Gunathilake, Wyatt Sharber, Luis Vargas, DQG &KULVWLQH 3DUGR as well as volunteers and members of the Gifford Arboretum Advisory Committee, Julie Dow and Lenny Goldstein.
