Comparative Anatomy of Ovules in Galinsoga, Solidago and Ratibida (Asteraceae)
ACTA BIOLOGICA CRACOVIENSIA Series Botanica 56/2: 115–125, 2014 DOI: 10.2478/abcsb-2014-0024 COMPARATIVE ANATOMY OF OVULES IN GALINSOGA, SOLIDAGO AND RATIBIDA (ASTERACEAE) JOLANTA KOLCZYK1, PIOTR STOLARCZYK2, AND BARTOSZ J. PŁACHNO1* 1Department of Plant Cytology and Embryology, Jagiellonian University, Gronostajowa 9, 30-387 Cracow, Poland 2Unit of Botany and Plant Physiology, Institute of Plant Biology and Biotechnology, University of Agriculture in Cracow, Al. 29 Listopada 54, 31-425 Cracow, Poland Manuscript submitted September 9, 2014; revision accepted October 22, 2014 Many Asteraceae species have been introduced into horticulture as ornamental or interesting exotic plants. Some of them, including Solidago and Galinsoga, are now aggressive weeds; others such as Ratibida are not. Special modifications of the ovule tissue and the occurrence of nutritive tissue have been described in several Asteraceae species, including invasive Taraxacum species. This study examined whether such modifications might also occur in other genera. We found that the three genera examined – Galinsoga (G. quadriradiata), Solidago (S. canadensis, S. rigida, S. gigantea) and Ratibida (R. pinnata) – differed in their nutritive tissue structure. According to changes in the integument, we identified three types of ovules in Asteraceae: “Taraxacum” type (recorded in Taraxacum, Bellis, Solidago, Chondrilla), with well-developed nutritive tissue having very swollen cell walls of spongy structure; “Galinsoga” type (in Galinsoga), in which the nutritive tissue cells have more cyto- plasm and thicker cell walls than the other integument parenchyma cells, and in which the most prominent character of the nutritive tissue cells is well-developed rough ER; and “Ratibida” type (in Ratibida), in which the nutritive tissue is only slightly developed and consists of large highly vacuolated cells. -

SOLIDAGO BRENDIAE ABSTRACT a New Species of S
Semple, J.C. 2013. A new species of Triplinerviae goldenrod in eastern Canada (Asteraceae: Astereae): Solidago brendiae . Phytoneuron 2013-57: 1–9. Published 21 August 2013 ISSN 2153 733X A NEW SPECIES OF TRIPLINERVIAE GOLDENROD IN EASTERN CANADA (ASTERACEAE: ASTEREAE): SOLIDAGO BRENDIAE JOHN C. SEMPLE Department of Biology University of Waterloo Waterloo, Ontario Canada N2L 3G1 [email protected] ABSTRACT A new species of Solidago is described from collections made in Maritime Canada. Fernald (1915, 1950) treated some of these plants as S. lepida var. elongata , which is native to far western North America. Comparison of these entire to sharply and coarsely serrate narrower leaved specimens that are sparsely hairy to glabrate with S. canadensis and the broader leaved and sometimes more hairy specimens of the S. lepida complex from Quebec, Newfoundland, New Brunswick, Nova Scotia, and Prince Edward Island indicate that Fernald was correct in recognizing two closely related races native to the Canadian Maritimes that are similar to the mostly western S. lepida, but they are treated here as varieties of S. fallax. Fernald was incorrect in thinking that the narrower leaved race belonged in S. elongata . These three eastern taxa are diploid while the S. lepida infrequently occurring in the Maritimes is hexaploid. All four taxa are usually more stipitate- glandular and have more leafy inflorescences with ascending branches than in sometimes similar S. canadensis . The following new name and combinations are proposed: Solidago brendiae Semple, sp. nov. , Solidago fallax (Fernald) Semple, comb. et stat. nov. , and Solidago fallax var. molina (Fernald) Semple, comb. nov.

TRIPLINERVIVAE IN WESTERN NORTH AMERICA: THE SOLIDAGO LEPIDA COMPLEX (ASTERACEAE: ASTEREAE) JOHN C. SEMPLE , HARIS FAHEEMUDDIN , MARIAN K. SOROUR , AND Y. ALEX CHONG Department of Biology University of Waterloo Waterloo, Ontario Canada N2L 3G1 [email protected] ABSTRACT Solidago subsect. Triplinerviae includes four species native to western North America: S. altissima, S. elongata , S. gigantea, and S. lepida . All of these except S. gigantea have been included at one time or another within S. canadensis . While rather similar among themselves, each species is distinguished by different sets of indument, leaf, and inflorescence traits. A series of multivariate morphometric analyses were performed on 244 specimens to discover additional technical traits useful in separating the species and to elucidate problems with identification in a group of species complicated by multiple ploidy levels and considerable infraspecific variation. Statistical support for recognizing S. gigantea var. shinnersii and S. lepida var. salebrosa was generated in comparisons of the varieties with the typical variety in each species. Solidago subsect. Triplinerviae (Torrey & A. Gray) Nesom (Asteraceae: Astereae) includes 17 species native North and South America (Semple 2017 frequently updated). Semple and Cook (2006) recognized 11 species with infraspecific taxa in several species occurring in Canada and the USA: S. altiplanities Taylor & Taylor, S. altissima L., S. canadensis L., S. elongata Nutt., S. -
Floristic Quality Assessment Report
FLORISTIC QUALITY ASSESSMENT IN INDIANA: THE CONCEPT, USE, AND DEVELOPMENT OF COEFFICIENTS OF CONSERVATISM Tulip poplar (Liriodendron tulipifera) the State tree of Indiana June 2004 Final Report for ARN A305-4-53 EPA Wetland Program Development Grant CD975586-01 Prepared by: Paul E. Rothrock, Ph.D. Taylor University Upland, IN 46989-1001 Introduction Since the early nineteenth century the Indiana landscape has undergone a massive transformation (Jackson 1997). In the pre-settlement period, Indiana was an almost unbroken blanket of forests, prairies, and wetlands. Much of the land was cleared, plowed, or drained for lumber, the raising of crops, and a range of urban and industrial activities. Indiana’s native biota is now restricted to relatively small and often isolated tracts across the State. This fragmentation and reduction of the State’s biological diversity has challenged Hoosiers to look carefully at how to monitor further changes within our remnant natural communities and how to effectively conserve and even restore many of these valuable places within our State. To meet this monitoring, conservation, and restoration challenge, one needs to develop a variety of appropriate analytical tools. Ideally these techniques should be simple to learn and apply, give consistent results between different observers, and be repeatable. Floristic Assessment, which includes metrics such as the Floristic Quality Index (FQI) and Mean C values, has gained wide acceptance among environmental scientists and decision-makers, land stewards, and restoration ecologists in Indiana’s neighboring states and regions: Illinois (Taft et al. 1997), Michigan (Herman et al. 1996), Missouri (Ladd 1996), and Wisconsin (Bernthal 2003) as well as northern Ohio (Andreas 1993) and southern Ontario (Oldham et al. -

The Vascular Flora of the Natchez Trace Parkway
THE VASCULAR FLORA OF THE NATCHEZ TRACE PARKWAY (Franklin, Tennessee to Natchez, Mississippi) Results of a Floristic Inventory August 2004 - August 2006 © Dale A. Kruse, 2007 © Dale A. Kruse 2007 DATE SUBMITTED 28 February 2008 PRINCIPLE INVESTIGATORS Stephan L. Hatch Dale A. Kruse S. M. Tracy Herbarium (TAES), Texas A & M University 2138 TAMU, College Station, Texas 77843-2138 SUBMITTED TO Gulf Coast Inventory and Monitoring Network Lafayette, Louisiana CONTRACT NUMBER J2115040013 EXECUTIVE SUMMARY The “Natchez Trace” has played an important role in transportation, trade, and communication in the region since pre-historic times. As the development and use of steamboats along the Mississippi River increased, travel on the Trace diminished and the route began to be reclaimed by nature. A renewed interest in the Trace began during, and following, the Great Depression. In the early 1930’s, then Mississippi congressman T. J. Busby promoted interest in the Trace from a historical perspective and also as an opportunity for employment in the area. Legislation was introduced by Busby to conduct a survey of the Trace and in 1936 actual construction of the modern roadway began. Development of the present Natchez Trace Parkway (NATR) which follows portions of the original route has continued since that time. The last segment of the NATR was completed in 2005. The federal lands that comprise the modern route total about 52,000 acres in 25 counties through the states of Alabama, Mississippi, and Tennessee. The route, about 445 miles long, is a manicured parkway with numerous associated rest stops, parks, and monuments. Current land use along the NATR includes upland forest, mesic prairie, wetland prairie, forested wetlands, interspersed with numerous small agricultural croplands. -
Solidago Canadensis Plants from Regular Soils Perform Better
Evidence for Enhanced Mutualism Hypothesis: Solidago canadensis Plants from Regular Soils Perform Better Zhen-Kai Sun, Wei-Ming He* State Key Laboratory of Vegetation and Environmental Change, Institute of Botany, Chinese Academy of Sciences, Beijing, China Abstract The important roles of plant-soil microbe interactions have been documented in exotic plant invasion, but we know very little about how soil mutualists enhance this process (i.e. enhanced mutualism hypothesis). To test this hypothesis we conducted two greenhouse experiments with Solidago canadensis (hereafter Solidago), an invasive forb from North America, and Stipa bungeana (hereafter Stipa), a native Chinese grass. In a germination experiment, we found soil microbes from the rhizospheres of Solidago and Stipa exhibited much stronger facilitative effects on emergence of Solidago than that of Stipa. In a growth and competition experiment, we found that soil microbes strongly facilitated Solidago to outgrow Stipa, and greatly increased the competitive effects of Solidago on Stipa but decreased the competitive effects of Stipa on Solidago. These findings from two experiments suggest that in situ soil microbes enhance the recruitment potential of Solidago and its ability to outcompete native plants, thereby providing strong evidence for the enhanced mutualism hypothesis. On the other hand, to some extent this outperformance of Solidago in the presence of soil microbes seems to be unbeneficial to control its rapid expansion, particularly in some ranges where this enhanced mutualism dominates over other mechanisms.

By early summer the flowering of prairie plants was unusually good and most of the woody growth was effec tively controlled. A July spot treatment of sprouts with 2-4-D should make possible longer intervals between burning in the future with adequate control. The study of resprouting, however, indicates that fIre alone doesn't kill the trees and shrubs in such sites and probably is not alone responsible for the treelessness of true prairies in the border region as some authors have sug gested. Bur oaks over one and one half inches in diameter survive with littlp. damage while practically all woody species resprout readily and the denser shrub thickets are damaged only at the edges. This area has been visited regularly for several years by plant ecology classes from The University of Wisconsin-Milwaukee and The University of Wisconsin-Kenosha, as well as by Nature Conservancy groups and individuals.
