For the most part, however, the work done has been with small groups of plants or with the plants of small political, ecological, or geological subdivisions of the state. Notable attempts to integrate these studies are the annotated check-list of Iowa plants (Cratty, 1933) based on the specimens in the Iowa State College herbarium and the keys to the Iowa flora (Conard, 19 51) based largely on the plants listed by Cratty. In recent years, knowledge of the Iowa flora has been advanced considerably both as the result of floristic studies that have been completed or initiated in eastern, southern, and western sections of the state and as the result of state­ wide or regional treatments of difficult families and genera. However, as has been pointed out by Thorne (1954), a complete and modern treatment of the Iowa flora such as is now avail­ able for many midwestern states cannot be prepared until all sections of the state have been studied in some detail. It is the purpose of this study to fill one of the re­ maining gaps in the knowledge of the Iowa flora and to present keys and an annotated check-list which will assist others who wish to continue with this work. The area selected for study is that part of north-central Iowa which was glaciated during the most recent advances of 2 the Wisconsin Glacier in Iowa. Thia area, known as and here­ after referred to as the Des Moines Lobe includes approxi­ mately 12,000 square miles in a tongue-shaped area about 90 miles wide and 140 miles long (Fig. 1, adapted after Ruhe, 19 52b).

MANKATO DRIFT BORDER CARY DRIFT BORDER 5 PROCEDURE During the growing seasons of 1955 and 1956 the author collected approximately 3000 specimens from the area of the Des Moines Lobe. Collections were made in as many types of habitat possible except that major effort was concentrated on those areas where previous collecting had not been extensive ('Thome, 1954). Selection of collecting areas was on the basis of a study of the aerial photographs prepared for the Iowa Agricultural Stabilization and Conservation Committee. From these photographs it was possible to select several hundred small areas of potential value and plot this informa­ tion on general highway maps for use in the field during the growing season. Of the many areas finally examined in the field, those which proved to be the most useful were the rights-of-way along railroads and secondary roads, particu­ larly where these rights-of-way are parallel and adjacent to one another. Other collecting sites revealed by the survey included unpastured woodlots, steep morainal hills and low or swampy places where artificial drainage had not been intro­ duced. The remainder of the approximately £5,000 specimens exam­ ined during the course of this study were previously collected by a number of students of the Iowa flora, including L. H. Pammel, Ada Hayden, R. I. Cratty, M. P. Somes, 0. K. Oleson, B. 0. Wold en, and more recently K. L. Grant, R. F. Thome, 6 R. W. Pohl and Duane Isely. All of the specimens examined are now on file in the herbarium of Iowa State University at Ames, Iowa. The keys and check-list which follow are based primarily on these specimens with additional date from a number of re­ gional and local floras and a large number of monographs and other botanical papers. Although all of these books and papers are included in the bibliography accompanying this paper, the author wishes to acknowledge especially the help derived from the following: Summer and winter keys to trees of the north central states (Alkmsn, 1957). Manual of cultivated plants (Bailey, 1949). Plants of Iowa (Conard, 1951). Flora of Indiana (Dean1, 1940). Gray1 s manual of botany, 8th ed. (Fernald, 1950), Vascular plants of Illinois (Jones and Fuller, 1955). The new Britton and Brown illustrated flora (Gleason, 1952). Flora of Illinois (Jones, 1945). Taxonomy of vascular niants (Lawrence, 1951). Check list of native and naturalized trees of the United States (Little, 195-3). Keys to the families of flowering niants of Story County (Pohl, 19 58). 7 Trees and shrubs of the Upper Midwest (Rosencahl, 1955). The arrangement of families and in most instances the circumscription of families, genera and species is that of the eighth edition of Gray's Manual. Exceptions to this general­ ization are indicated by reference to another author or group of authors in the appropriate part of the text. Within each family, genera and species have been listed in alphabetical order. with certain exceptions noted below, the keys and check­ list account for all species of flowering plants known by the author to be native or naturalized in the area of the Des Koines Lobe in Iowa. Included also are a number of families, genera and species which are occasionally adventive or merely cultivated In the area. In certain instances these taxa are included in the keys but not in the check-list. Such in­ stances are designated by an asterisk preceding the name of t:ie taxon. For each species in the check-list there is included a listing of frequently encountered synonyms, common names in general use, notes on habitat, range within the Des Moines Lobe, frequency or abundance and flowering dates. This in­ formation has been summarized from the labels on the specimens examined during the course of the study. For those species which are quite rare, a complete citation is included for each specimen examined. 8 Excluded from this study are the Gramineae and the Leguminosae, families which are currently being studied and revised at Iowa State University under the direction of R. W. Pohl and Duane Isely, respectively. Several genera have also been excluded either because they present problems beyond the scope of this study or because they have recently been treated in papers dealing specifically with the Iowa flora. These genera are Carex L., Rubus L., Crataep-us L. and Viola L. All of these taxa are included in the general keys but are not treated in further detail. 9 DESCRIPTION OF THE AREA Although an analysis of the factors affecting the distri­ bution of plants In Iowa Is beyond the scope of this study, the following summary of these factors es they pertain to the Des Moines Lobe is presented as a means of clearly defining the area studied and as a guide to those who may wish to do further work in the area. Geology The geological history of Iowa is quite well known and will not be discussed in detail. It is desirable, however, to consider the events of the Pleistocene Epoch because of the effect they have had on the topography, soils and subsequently the vegetation of the area under consideration. During the Pleistocene, Iowa was Invaded by four succes­ sive, glacial ice sheets, the Nebraskan, the Kansan, the Illi- noian and the Wisconsin, respectively. Of these only the last need ce considered here, the effects of the others having been negated by the later glaciation. As it is now understood (Ruhe, 1952a), the Wisconsin Glacier Invaded Iowa in four substages, the Iowa, the Taze­ well, the Gary and the Mankato. The lowan and somewhat more recent Tazewell substages covered most of the northern half of Iowa during the period of their most extreme advances. A warming trend followed during which loess we s deposited on too 10 of the glacial debris. This loess is surface material in most of eastern, southern and western Iowa at the present time. The reinvasion of glacial ice in Iowa during the Gary substage took the form of a broad, somewhat irregular, tongue- shaped lobe about 90 miles wide and 140 miles long. This is the area now known as the Des Moines Lobe and its limits in Iowa are the limits of the area under consideration in this study (Fig.

    Fruits: Kinds and Terms

    FRUITS: KINDS AND TERMS THE IMPORTANT PART OF THE LIFE CYCLE OFTEN IGNORED Technically, fruits are the mature ovaries of plants that contain ripe seeds ready for dispersal • Of the many kinds of fruits, there are three basic categories: • Dehiscent fruits that split open to shed their seeds, • Indehiscent dry fruits that retain their seeds and are often dispersed as though they were the seed, and • Indehiscent fleshy fruits that turn color and entice animals to eat them, meanwhile allowing the undigested seeds to pass from the animal’s gut We’ll start with dehiscent fruits. The most basic kind, the follicle, contains a single chamber and opens by one lengthwise slit. The columbine seed pods, three per flower, are follicles A mature columbine follicle Milkweed seed pods are also large follicles. Here the follicle hasn’t yet opened. Here is the milkweed follicle opened The legume is a similar seed pod except it opens by two longitudinal slits, one on either side of the fruit. Here you see seeds displayed from a typical legume. Legumes are only found in the pea family Fabaceae. On this fairy duster legume, you can see the two borders that will later split open. Redbud legumes are colorful before they dry and open Lupine legumes twist as they open, projecting the seeds away from the parent The bur clover modifies its legumes by coiling them and providing them with hooked barbs, only opening later as they dry out. The rattlepods or astragaluses modify their legumes by inflating them for wind dispersal, later opening to shed their seeds.

These surface structures implies that the arachnoids or the group may have had were first discovered on the Venera 15/16 radar images several evolution phases. and later defined in detail by the Magellan mission [2, 3]. The arachnoids have a peculiar distribution, which is generally different to that of the coronae and particu- larly the novae [4]. The global distribution of arach- noids reflects certain noticeable facts: There is a clear concentration of arachnoid features in the northern hemisphere as 65,6 percent (63 feat.) of the features is located there, while only 34,4 percent (33 feat.) of the population is located in the southern hemisphere [5]. In addition, the arachnoids form four large groups which include roughly 25 % of the total population. The arachnoids of Bereghinya and Ganiki Planitia: The arachnoid group of Bereghinya Planitia is by far the largest arachnoid concentration on Venus. The structural composition of the features of the group are generally distinct and the features are connected by a uniform, chain-like pattern of lineaments. Figure 2.

  • Ferns of the National Forests in Alaska

    Ferns of the National Forests in Alaska United States Forest Service R10-RG-182 Department of Alaska Region June 2010 Agriculture Ferns abound in Alaska’s two national forests, the Chugach and the Tongass, which are situated on the southcentral and southeastern coast respectively. These forests contain myriad habitats where ferns thrive. Most showy are the ferns occupying the forest floor of temperate rainforest habitats. However, ferns grow in nearly all non-forested habitats such as beach meadows, wet meadows, alpine meadows, high alpine, and talus slopes. The cool, wet climate highly influenced by the Pacific Ocean creates ideal growing conditions for ferns. In the past, ferns had been loosely grouped with other spore-bearing vascular plants, often called “fern allies.” Recent genetic studies reveal surprises about the relationships among ferns and fern allies. First, ferns appear to be closely related to horsetails; in fact these plants are now grouped as ferns. Second, plants commonly called fern allies (club-mosses, spike-mosses and quillworts) are not at all related to the ferns. General relationships among members of the plant kingdom are shown in the diagram below. Ferns & Horsetails Flowering Plants Conifers Club-mosses, Spike-mosses & Quillworts Mosses & Liverworts Thirty of the fifty-four ferns and horsetails known to grow in Alaska’s national forests are described and pictured in this brochure.

In this plan, we will briefly introduce the physical and biological setting, past land use, and current uses of the Domain. The remainder of the plan consists of an assessment of the forest, which has been divided into six conservation areas. These conservation areas contain multiple management compartments, and the six areas have similarities in topographical position and past land use. Finally, the desired future condition and project summary of each conservation area and compartment has been outlined. Background The University of the South consists of an academic campus (382 acres) with adjacent commercial and residential areas (783 acres) that are embedded within and surrounded by diverse natural lands (11,838 acres). The term “Domain” is used interchangeably to describe both the entire ~13,000 acres and the 11,800-acre natural land matrix (also referred to as the “Greater Domain”).

Executive Summary This survey was a continuation of several years of rare plant survey on San Juan Public Lands. Funding for the project was provided by San Juan National Forest and the San Juan Resource Area of the Bureau of Land Management. Previous rare plant surveys on San Juan Public Lands by CNHP were conducted in conjunction with county wide surveys of La Plata, Archuleta, San Juan and San Miguel counties, with partial funding from Great Outdoors Colorado (GOCO); and in 2004, public lands only in Dolores and Montezuma counties, funded entirely by the San Juan Public Lands. Funding for 2005 was again provided by San Juan Public Lands. The primary emphases for field work in 2005 were: 1. revisit and update information on rare plant occurrences of agency sensitive species in the Colorado Natural Heritage Program (CNHP) database that were last observed prior to 2000, in order to have the most current information available for informing the revision of the Resource Management Plan for the San Juan Public Lands (BLM and San Juan National Forest); 2.

A few of these were not happy in their location and promptly died, or did so poorly as to warrant their removal. A few new varie- ties were added to the original group, but for the most part these trees have been growing there s~nce the trial plot was first laid out. The collection has been of special interest to home owners in the suburban areas of Boston, who naturally are interested in small ornamental trees. It has also been of considerable interest to the tree wardens of various towns throughout New England, for here one may see many of the best small trees growing side by side, so that comparisons can be easily made. Recently this plot has been of interest to the Electric Council of New England, a group of utility companies which provide various electric services for the public in addition to stringing electric lines for these services. When the right kinds of trees are planted properly in the right places along the streets and highways, there need be but little competition between the trees and the wires.
