Hairy Beardtongue (Penstemon hirsutus) Checklist Flora of the Former Carden Township, City of Kawartha Lakes, ON 2016 Compiled by Dale Leadbeater and Anne Barbour © 2016 Leadbeater and Barbour All Rights reserved. No part of this publication may be reproduced, stored in a retrieval system or database, or transmitted in any form or by any means, including photocopying, without written permission of the authors. Produced with financial assistance from The Couchiching Conservancy. The City of Kawartha Lakes Flora Project is sponsored by the Kawartha Field Naturalists based in Fenelon Falls, Ontario. In 2008, information about plants in CKL was scattered and scarce. At the urging of Michael Oldham, Biologist at the Natural Heritage Information Centre at the Ontario Ministry of Natural Resources and Forestry, Dale Leadbeater and Anne Barbour formed a committee with goals to: • Generate a list of species found in CKL and their distribution, vouchered by specimens to be housed at the Royal Ontario Museum in Toronto, making them available for future study by the scientific community; • Improve understanding of natural heritage systems in the CKL; • Provide insight into changes in the local plant communities as a result of pressures from introduced species, climate change and population growth; and, • Publish the findings of the project . Over eight years, more than 200 volunteers and landowners collected almost 2000 voucher specimens, with the permission of landowners. Over 10,000 observations and literature records have been databased. The project has documented 150 new species of which 60 are introduced, 90 are native and one species that had never been reported in Ontario to date.

Hawkweeds: State Prohibited Weed (DPI Vic)
June 2003 Hawkweeds: State Prohibited Weed LC0376 Keith Turnbull Research Institute, Frankston ISSN 1329-833X This Landcare Note describes Hieracium spp., hawkweeds, as State Prohibited Weeds in Victoria. Common name Hawkweeds Scientific name Hieracium spp. Family Asteraceae (daisies) Status Hieracium species are proclaimed as a State Prohibited Weed in Victoria. This means that Hieracium spp. are to be eradicated if possible from the State. Hieracium species are also proclaimed weeds in New South Wales, Western Australia and Tasmania and have been classified as prohibited imports by the Australian Quarantine and Inspection Service. There are between 700 and 1000 world species of Hieracium, mostly native to the Northern Hemisphere in temperate and montane areas, but with some species in South America and southern Africa. No species are native to Australia. Orange hawkweed Hieracium aurantiacum, native to Europe, is the only species known to have become naturalised in Victoria. Small infestations are known from Falls Creek and Mt Hotham. Other hawkweed species have been available from nurseries and markets and are likely to be present in gardens. Description Herbs with milky sap, often hairy, with a basal rosette of leaves. The group is divided into two subgenera: Pilosella, which contains perennial, stoloniferous, often mat-forming species that reproduce sexually, and Hieracium, which contains annual, non-stoloniferous species, that reproduce asexually by seed and produce little pollen. Commonly each species is highly variable and contains several subspecies. Hybrids occur frequently. Stems – erect, the creeping stolons root readily at the nodes, like a strawberry plant. Leaves – in a basal rosette or alternate on the stems, entire or toothed, rarely lobed, often hairy.

Hawkweed Hieracium and Pilosella Species
Hawkweed Hieracium and Pilosella species Family Asteraceae (daisy) Also known as Tussock hawkweed (Hieracium lepidulum), spotted hawkweed (Hieracium pollichiae), Hieracium argillaceum, Hieracium murorum, Hieracium sabaudum, mouse-eared hawkweed (Pilosella officinarum, syn. Hieracium pilosella), orange hawkweed (Pilosella aurantiaca subsp. carpathicola), king devil (Pilosella piloselloides subsp. praealta, syn. Hieracium praealtum), field hawkweed (Pilosella caespitosa), Pilosella × stoloniflora Where is it originally from? Europe What does it look like? Perennial herbs that form mats of tight, interconnected rosettes with Photo: Carolyn Lewis thick underground root systems, and often with above-ground root systems (stolons) as well. Leaves (25-150 x 6-50 cm) are dull green to dark green above, usually paler (occasionally purplish) below, with those at the base of the plant usually slightly toothed, and with bristly hairs above and star-shaped hairs below. Thin stems (10-75 cm) have milky sap. Lemon or yellow dandelion-like flowers (orange, purple when dry, in H. aurantiacum and H. x stoloniflorum, Oct-May), which occasionally have red stripes on outer face and are followed by fluffy seeds with dirty-white hairs (4-8 mm, Oct-May). Are there any similar species? Hawksbeard (Crepis), hawkbit (Leontodon) and catsear (Hypochoeris) species. Photo: Carolyn Lewis Why is it weedy? Grows and matures quickly, producing many moderately long-lived and widely dispersed seeds. Creeping, mat-forming habit enables it to tolerate damage and grazing, moderate to cold temperatures, low rainfall, poor soils, and little shade. It produces substances in the soil that discourages other species from growing near it (allelopathic). How does it spread? Seed is spread by wind, and in clothing and animal pelts.

Cryptic Host-Associated and Frequency-Dependent Patterns of Host Species Selection of a Candidate Weed Biological Control Agent in Its Native Range
CRYPTIC HOST-ASSOCIATED AND FREQUENCY-DEPENDENT PATTERNS OF HOST SPECIES SELECTION OF A CANDIDATE WEED BIOLOGICAL CONTROL AGENT IN ITS NATIVE RANGE by CHANDRA ELAINE MOFFAT B.SC., THE UNIVERSITY OF VICTORIA, 2009 A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE in THE COLLEGE OF GRADUATE STUDIES (BIOLOGY) THE UNIVERSITY OF BRITISH COLUMBIA (OKANAGAN) AUGUST 2012 © CHANDRA ELAINE MOFFAT, 2012 ABSTRACT At least nine species of European hawkweeds in the genus Pilosella Vaill. (Asteraceae) are invasive in western North America, where they are a detriment to natural and managed lands and have vast economic impacts. A promising candidate biological control (biocontrol) agent for multiple species of Pilosella is the gall inducing wasp Aulacidea pilosellae Kieffer (Hymenoptera: Cynipidae). Initial studies of this candidate agent revealed the potential for two biotypes of the insect that differed in physiological host range, voltinism, and reproductive mode. It was hypothesized that these differences were related to geographic separation of the populations and it was further observed, within one subset of the distribution, that different host species were being used at nearby sites, despite similar host species being present. The overarching goal of this thesis was to increase the understanding of the patterns of host species use by A. pilosellae in order to inform the biocontrol programme for invasive Pilosella hawkweeds. The specific objectives were to (i) test the hypothesis that A. pilosellae has definitive preferences for species of Pilosella within its ecological host range, (ii) further quantify the ecological host range of A. pilosellae by conducting systematic surveys across a broad geographic distribution, and (iii) test the hypothesis that differences between the purported biotypes were due to cryptic genetic differentiation, predicted to be based primarily on geographic location of populations and secondly on host-association.

Red List of Vascular Plants of the Czech Republic: 3Rd Edition
Preslia 84: 631–645, 2012 631 Red List of vascular plants of the Czech Republic: 3rd edition Červený seznam cévnatých rostlin České republiky: třetí vydání Dedicated to the centenary of the Czech Botanical Society (1912–2012) VítGrulich Department of Botany and Zoology, Masaryk University, Kotlářská 2, CZ-611 37 Brno, Czech Republic, e-mail: [email protected] Grulich V. (2012): Red List of vascular plants of the Czech Republic: 3rd edition. – Preslia 84: 631–645. The knowledge of the flora of the Czech Republic has substantially improved since the second ver- sion of the national Red List was published, mainly due to large-scale field recording during the last decade and the resulting large national databases. In this paper, an updated Red List is presented and compared with the previous editions of 1979 and 2000. The complete updated Red List consists of 1720 taxa (listed in Electronic Appendix 1), accounting for more then a half (59.2%) of the native flora of the Czech Republic. Of the Red-Listed taxa, 156 (9.1% of the total number on the list) are in the A categories, which include taxa that have vanished from the flora or are not known to occur at present, 471 (27.4%) are classified as critically threatened, 357 (20.8%) as threatened and 356 (20.7%) as endangered. From 1979 to 2000 to 2012, there has been an increase in the total number of taxa included in the Red List (from 1190 to 1627 to 1720) and in most categories, mainly for the following reasons: (i) The continuing human pressure on many natural and semi-natural habitats is reflected in the increased vulnerability or level of threat to many vascular plants; some vulnerable species therefore became endangered, those endangered critically threatened, while species until recently not classified may be included in the Red List as vulnerable or even endangered.
