Toronto Master Gardeners Ask Plant Id Questions
TORONTO MASTER GARDENERS ASK PLANT ID QUESTIONS Image Question Answer Growing in ditches beside a gravel road It is challenging to identify a plant from a single leaf, and I consulted our team in Township of Perry 25 minutes north of Master Gardeners, several of whom feel that the plant is likely some sort of Huntsville. Cant find it in any of our of dock. Consider the following: reference books. Leaves are emerging from ground singly and veins are deep ñ Rumex sanguineus var.sanguineus (red-veined or bloody red. dock). See the Missouri Botanical Garden monograph ñ Rumex obtusifolius (broadleaved dock/ bitter dock). See Illinois Wildflowers – Bitter Dock ñ Rumex aquaticus (Scottish dock). See Nature Gate’s Scottish Dock Another suggestion was this might be pokeweed (Phytolacca Americana). See Ohio State University’s Ohio Perennial and Biennial Weed May 2019 Guide – Common PokeweedClick on the above links and you'll see photos that show that these plants have leaves that resemble those of your mystery plant, in many respects. However, with docks and the common pokeweed, leaves generally emerge from the same clump, not singly. As well, these plants have lance-shaped leaves, which seem to differ quite a bit from the oblong-shaped leaf of shown in the photo you submitted.Finally, it is possible that the plant is related to dock, but is a sorrel (Rumex acetosa) - some sorrels have leaves that are shaped more like the leaf in your photo. For example, see Nature Gate's Common sorrel My neighbour gave me this plant, that I Your neighbour gave you a Bergenia cordifolia, commonly called Bergenia or planted las year. -
The Relation Between Road Crack Vegetation and Plant Biodiversity in Urban Landscape
Int. J. of GEOMATE, June, 2014, Vol. 6, No. 2 (Sl. No. 12), pp. 885-891 Geotech., Const. Mat. & Env., ISSN:2186-2982(P), 2186-2990(O), Japan THE RELATION BETWEEN ROAD CRACK VEGETATION AND PLANT BIODIVERSITY IN URBAN LANDSCAPE Taizo Uchida1, JunHuan Xue1,2, Daisuke Hayasaka3, Teruo Arase4, William T. Haller5 and Lyn A. Gettys5 1Faculty of Engineering, Kyushu Sangyo University, Japan; 2Suzhou Polytechnic Institute of Agriculture, China; 3Faculty of Agriculture, Kinki University, Japan; 4Faculty of Agriculture, Shinshu University, Japan; 5Center for Aquatic and Invasive Plants, University of Florida, USA ABSTRACT: The objective of this study is to collect basic information on vegetation in road crack, especially in curbside crack of road, for evaluating plant biodiversity in urban landscape. A curbside crack in this study was defined as a linear space (under 20 mm in width) between the asphalt pavement and curbstone. The species composition of plants invading curbside cracks was surveyed in 38 plots along the serial National Route, over a total length of 36.5 km, in Fukuoka City in southern Japan. In total, 113 species including native plants (83 species, 73.5%), perennial herbs (57 species, 50.4%) and woody plants (13 species, 11.5%) were recorded in curbside cracks. Buried seeds were also obtained from soil in curbside cracks, which means the cracks would possess a potential as seed bank. Incidentally, no significant differences were found in the vegetation characteristics of curbside cracks among land-use types (Kolmogorov-Smirnov Test, P > 0.05). From these results, curbside cracks would be likely to play an important role in offering habitat for plants in urban area. -

Literature Cited Robert W. Kiger, Editor This is a consolidated list of all works cited in volumes 19, 20, and 21, whether as selected references, in text, or in nomenclatural contexts. In citations of articles, both here and in the taxonomic treatments, and also in nomenclatural citations, the titles of serials are rendered in the forms recommended in G. D. R. Bridson and E. R. Smith (1991). When those forms are abbre- viated, as most are, cross references to the corresponding full serial titles are interpolated here alphabetically by abbreviated form. In nomenclatural citations (only), book titles are rendered in the abbreviated forms recommended in F. A. Stafleu and R. S. Cowan (1976–1988) and F. A. Stafleu and E. A. Mennega (1992+). Here, those abbreviated forms are indicated parenthetically following the full citations of the corresponding works, and cross references to the full citations are interpolated in the list alphabetically by abbreviated form. Two or more works published in the same year by the same author or group of coauthors will be distinguished uniquely and consistently throughout all volumes of Flora of North America by lower-case letters (b, c, d, ...) suffixed to the date for the second and subsequent works in the set. The suffixes are assigned in order of editorial encounter and do not reflect chronological sequence of publication. The first work by any particular author or group from any given year carries the implicit date suffix “a”; thus, the sequence of explicit suffixes begins with “b”. Works missing from any suffixed sequence here are ones cited elsewhere in the Flora that are not pertinent in these volumes. -

China 2 Key Laboratory of Molecular Cytogenetics and Genetic Breeding of Heilongjiang Province; College of life Sciences and Technology, Harbin Normal University. Harbin 150025. P. R. China Abstract Understanding parameters that drive plant resource allocation for reproduction in potentially economically and environ- mentally important species, such as Kalimeris intergrifolia, is essential to maximize production rates. Hence, this study evaluates the characteristics in reproductive resource allocation of two K. intergrifolia communities at a saline-alkali open meadow and at a semi-enclosed secondary broad-leaved forest fringe, in the Songnen plains region of northeast China. Ramets from each habitat type were sampled at three intervals during the ripening stage (June-October). Relative resource distribution was quantified by measuring the dry weight of the above-ground ramet components, including the stem, leaf, corymb and seeds. The results indicated high variability in the distribution of resource allocation for both types, with larger phenotypic plasticity being recorded for the forest fringe than the open meadow. However, the allocation of re- sources into reproductive organs was higher in the open meadow than in the forest fringe, demonstrating that the open community was advantageous to the reproduction. -

In total, 111 compounds were identified, representing 98% of the essential oil. The essential oil was dominated by sesquiterpene (69.3%) and monoterpene hydrocarbons (15.9%), with germacrene D as the most abundant compound (34.7%). Several multivariant statistical methods (HCA, NJ, PCoA) were deployed to infer the relation between A. albanicus and other species belonging to this genus. Taxonomical implications are discussed.

The yellow coloured mous and non-diclinous species, respectively. The visual anthers and pollen and the similarly coloured flower guides similarity between the androecium and other floral organs are described as key features of a pollen and stamen is attributed to mimicry, i.e. deception caused by the flower mimicry system. In this study, we investigated the entire visitor’s inability to discriminate between model and angiosperm flora of the Alps with regard to visually dis- mimic, sensory exploitation, and signal standardisation played pollen and floral guides. All species were checked among floral morphs, flowering phases, and co-flowering for the presence of pollen- and stamen-imitating structures species. We critically discuss deviant pollen and stamen using colour photographs. Most flowering plants of the mimicry concepts and evaluate the frequent evolution of Alps display yellow pollen and at least 28% of the species pollen-imitating structures in view of the conflicting use of display pollen- or stamen-imitating structures. The most pollen for pollination in flowering plants and provision of frequent types of pollen and stamen imitations were pollen for offspring in bees. -

G.L.Nesom in Uttar Pradesh, India: A new record Amit Kumar Tripathi*, Jyoti Kumar Sharma Center for Environmental Sciences and Engineering, School of Natural Sciences, Shiv Nadar University, Greater Noida, Uttar Pradesh, India; * [email protected] Received: 01.01.2019 | Accepted: 02.02.2019 | Published: 07.02.2019 Abstract Symphyotrichum squamatum (Spreng.) G.L.Nesom, is an erect herb of the Compositae family, recorded from the campus of the Shiv Nadar University, Uttar Pradesh, India. The species is being recorded for the first time from India as there are no earlier reports of its occurrence in the literature. The taxonomic description of the plant along with colored illustrations of morphological characteristics such as habit, leaf, flower, root etc. are provided for easy identification of the species in wild. As the plant is known to have a tendency to spread rapidly, it may become an aggressive weed in India in near future. Keywords: Symphyotrichum squamatum, compositae, new record, Shiv Nadar University, India Introduction Subsequently, the occurrence of the species was also recorded at a few more places outside the SNU campus.
