The Atlas of the Vascular Plants of Utah This is a digital version of the Atlas of the Vascular Plants of Utah authored by Beverly J. Albee, Leila M. Shultz, and Sherel Goodrich, published by the Utah Museum of Natural History, 1988. The original document consists of maps of the state of Utah showing collection locations for 2,438 documented plant species. The authors critically examined approximately 400,000 specimens during a seven year time span to create the original paper atlas. Each location contained in the original atlas was hand-digitized into a Geographic Information System. This database contains over 72,000 individual collection locations within the state of Utah. We have organized this digital document by plant family name. Individual species and their maps are located under the appropriate family. Aceraceae Agavaceae Aizoaceae Alismataceae ...

Common names are not always available for every plant and can also be very confusing as the same name may be given to many different species.

Local Flora Vascular Plants of North Central Florida INTRODUCTION Revised by R. Anthony Miller University of Florida Herbarium Florida Museum of Natural History 379 Dickinson Hall PO Box 110575 Gainesville, FL 32611-0575 Web version of Circular 451, Cooperative Extension Service, University of Florida, Institute of Food and Agricultural Sciences, Gainesville, FL Intro Ferns Vines Trees and Shrubs ... Herbs The following checklist represents a revision of Local Flora - Vascular Plants of North Central Florida by Dana G. Griffin, III (1978). This checklist was derived from existing lists and expanded through observations made during several University of Florida field courses and a study of records at the University of Florida Herbarium. The names of several species listed in the 1978 publication have been deleted, while those of many previously unlisted species have been added. The primary focus of this revision is the standardization of common names. I do not claim that this checklist is complete, nor do I expect it to be free from error. My intent was to list the more common or biologically interesting species found in north central Florida as a guide for those studying the plant life of the region. I am grateful to the staff of the University of Florida Herbarium for the use of their facilities during the preparation of this checklist. I also greatly appreciate the assistance I have received from many individuals, particularly, Dr. D. G. Griffin and Dr. D. B. Ward. I wish to thank Kent D. Perkins, Collection Manager at the UF Herbarium for his editorial suggestions. Comments regarding editorial matters should be addressed to him.

The nature of pre-Devonian tracheid-like tubes Piotr Mierzejewski Graptolite Net Organic Microfossils Scolecodonts ... Amber In the course of my studies of Ordovician and Silurian organic microfossils I have found, however, an aberrant benthic graptolite of an uncertain taxonomic position. This form, described as Maenniligraptus ursulae Stolons of Maennilligraptus ursulae with characteristic inner rings and spiral thickenings. Piotr Mierzejewski, the Count of Calmont and Goethe Lab - Centrum Paleobiologii Moreover, I suggest that some of the tracheid-like tubes should also be assigned to rhabdopleurids. It has been a common belief among palaeontologists up till very recently that fossil remnants of the Rhabdopleuroidea are extremely rare. The first Silurian rhabdopleurid was described in 1977 ( Mierzejewski 1977 ). Later, I found that the Early Palaeozoic genera Cylindrotheca Eisenack, 1934 and Kystodendron Koz³owski, 1959, described as 'chitinous' hydroids, represent in fact stolons connected with sterile cyst buds of rhabdopleurid coenecia ( Mierzejewski 1986 ). The zooidal tubes of these forms, consisting of encircling fusellar rings, closely resemble some tracheid-like tubes. The diameter of the zooidal tubes in

Home Botany 1050 Introduction to Botany Spring 2005 INTRODUCTION TO VASCULAR PLANTS I. Two major types of true plants: A. Vascular (higher) plants: 1. Have true conducting tissues (xylem and phloem), leaves, stems and roots 2. The sporophytes are the dominant phase and the gametophytes are much reduced 3. Constitutes the majority of plants B. Non-vascular (lower) plants 1. Lack true conducting tissues, leaves and roots. Since they lack elaborate conducting tissues they are relatively small 2. The gametophytes are the dominant phase and the sporophytes are dependent upon them 3. Require water for fertilization so they must grow in moist or seasonally moist habitats II. Earliest land plants: A. The invasion of land by plants probably occurred about 450 million years ago because by 430 million years ago there were many fossil land plants B. The earliest land plants were relatively simple and undifferentiated (see p. 433) 1. They had dichotomously branched photosynthetic axes that lacked true leaves and roots 2. Specialization led to differentiation of these simple axes into roots, stems and leaves
