It is the responsibility of the sender to inform the Trials Office at Wisley that all queries have been resolved. SUBJECT TO AVAILABILITY H4 Trial Notes: Objectives: The objectives of the trial were: • To assess a range of hardy annuals, including some more unusual entries • To demonstrate a range of direct sown hardy annuals to the public • To recommend the Award of Garden Merit [AGM] to cultivars considered excellent for ordinary garden use. Entries: There were 157 entries in the trial, submitted by various seed companies in the UK and Europe. Cultivation: Seed was sown direct on 6 May. Spacing: Triploid and larger cultivars were spaced 45 cm each way, all other entries were spaced 30cm apart each way in blocks with 40cm between entries. 25 plants of the single coloured cultivars are being grown and 50 plants of the mixtures. Judging: The Floral Trials Subcommittee assessed entries in the trial for the Award of Garden Merit on 8 July, 22 July, 6 August, 21 August, 2 and 16 September using the following criteria: length of flowering period : colour : impact : habit : uniformity of single colours : balance of mixtures : true to flower shape/form. Findings: 10/6/08 The committee walked the trial – most entries (over 200) had germinated and some were slightly congested. It was suggested that some be thinned (the Clarkia in bed 1 in particular should be thinned to 3-5 seedlings/station) and with others weeds and seedlings outside the rows be removed. 24/6/08 Tony Hender and Keith Sangster inspected the trial of hardy annuals that had been sown direct in May and reported back that there were just two or three starting to flower and the trial looked very good and the trials staff should be congratulated on the difficult cultivation required by this impromptu demonstration. 6/8/08 The Committee recommended that some of the hardy annuals in this demonstration would make a valuable and informative addition to the floral display at Wisley and thought that David Jewell may be interested to have a look at the trial with this in mind. 5 The Committee requested that 1/3 of a row of each entry be sheered back to around 3” to see which entries produce a second flush of flowers. 21/8/08 It was noted that ideally clarkias need more space and that the sowing time is critical to ensure good performance. A number were looking bare around the base of the stems. 16/9/08 The trial was assessed for the last time and would be cleared by the end of September.

Um diesem Rückgang Einhalt zu gebieten, wurden verschiedene Artenschutzkonzepte wie das Ackerrandstreifenprogramm oder das aktuelle Programm ‘100 Äcker für die Vielfalt’ entwickelt. Für Sand- und Kalkäcker sind geeignete Bewirtschaftungsmethoden zur Erhaltung seltener Arten inzwischen gut erforscht. Für saisonal vernässte Ackerflächen, die ebenfalls viele seltene Arten aufweisen können, ist dagegen wenig über naturschutzfachlich geeignet Standortfaktoren und Bewirtschaftungsmethoden bekannt. Untersuchungen an sieben zeitweise überstauten Ackersenken bei Parstein (Brandenburg) zeigten, dass das Überstauungsregime und insbesondere die Dauer der Überstauung die Artenzusammensetzung

  • Gymnaconitum, a New Genus of Ranunculaceae Endemic to the Qinghai-Tibetan Plateau
    TAXON 62 (4) • August 2013: 713–722 Wang & al. • Gymnaconitum, a new genus of Ranunculaceae Gymnaconitum, a new genus of Ranunculaceae endemic to the Qinghai-Tibetan Plateau Wei Wang,1 Yang Liu,2 Sheng-Xiang Yu,1 Tian-Gang Gao1 & Zhi-Duan Chen1 1 State Key Laboratory of Systematic and Evolutionary Botany, Institute of Botany, Chinese Academy of Sciences, Beijing 100093, P.R. China 2 Department of Ecology and Evolutionary Biology, University of Connecticut, Storrs, Connecticut 06269-3043, U.S.A. Author for correspondence: Wei Wang, [email protected] Abstract The monophyly of traditional Aconitum remains unresolved, owing to the controversial systematic position and taxonomic treatment of the monotypic, Qinghai-Tibetan Plateau endemic A. subg. Gymnaconitum. In this study, we analyzed two datasets using maximum likelihood and Bayesian inference methods: (1) two markers (ITS, trnL-F) of 285 Delphinieae species, and (2) six markers (ITS, trnL-F, trnH-psbA, trnK-matK, trnS-trnG, rbcL) of 32 Delphinieae species. All our analyses show that traditional Aconitum is not monophyletic and that subgenus Gymnaconitum and a broadly defined Delphinium form a clade. The SOWH tests also reject the inclusion of subgenus Gymnaconitum in traditional Aconitum. Subgenus Gymnaconitum markedly differs from other species of Aconitum and other genera of tribe Delphinieae in many non-molecular characters. By integrating lines of evidence from molecular phylogeny, divergence times, morphology, and karyology, we raise the mono- typic A. subg. Gymnaconitum to generic status. Keywords Aconitum; Delphinieae; Gymnaconitum; monophyly; phylogeny; Qinghai-Tibetan Plateau; Ranunculaceae; SOWH test Supplementary Material The Electronic Supplement (Figs.

NeoBiota 45: 93–115. https://doi.org/10.3897/neobiota.45.33866 Abstract River ports represent a special type of urbanized area. They are considered to be an important driver of biological invasion and biotic homogenization on a global scale, but it remains unclear how and to what degree they serve as a pool of alien species. Data for 54 river ports (16 German, 20 Czech, 7 Hungarian, 3 Slovak, and 8 Austrian ports) on two important Central European waterways (the Elbe-Vltava and Dan- ube waterways) were collected over 40 years. In total, 1056 plant species were found. Of these, 433 were alien, representing 41% of the total number of species found in all the studied Elbe, Vltava, and Danube ports. During comparison of floristic data from literary sources significant differences in the percentage of alien species in ports (50%) and cities (38%) were found.

Brentwood Blvd. St. Louis, Missouri 63144 [email protected] JUSTIN R. THOMAS Institute of Botanical Training, LLC 111 County Road 3260 Salem, Missouri 65560 [email protected] ABSTRACT An annotated checklist of the 2,961 vascular taxa comprising the flora of Missouri is presented, with conservatism rankings for Floristic Quality Assessment. The list also provides standardized acronyms for each taxon and information on nativity, physiognomy, and wetness ratings. Annotated comments for selected taxa provide taxonomic, floristic, and ecological information, particularly for taxa not recognized in recent treatments of the Missouri flora. Synonymy crosswalks are provided for three references commonly used in Missouri. A discussion of the concept and application of Floristic Quality Assessment is presented. To accurately reflect ecological and taxonomic relationships, new combinations are validated for two distinct taxa, Dichanthelium ashei and D. werneri , and problems in application of infraspecific taxon names within Quercus shumardii are clarified.

Explanatory variables were recorded for each field to elucidate the role of large- scale spatial trends, site specific, abiotic environmental conditions and field management characters. Redundancy analysis was used to assess the relative importance of each environmental variable in explaining the variation in species composition. Our results indicate that variation in weed species composition is strongly determined by altitude, mean annual precipitation, mean annual temperature and also by different soil characteristics.

Introduction Plant Protection and Quarantine (PPQ) regulates noxious weeds under the authority of the Plant Protection Act (7 U.S.C. § 7701-7786, 2000) and the Federal Seed Act (7 U.S.C. § 1581-1610, 1939). A noxious weed is defined as “any plant or plant product that can directly or indirectly injure or cause damage to crops (including nursery stock or plant products), livestock, poultry, or other interests of agriculture, irrigation, navigation, the natural resources of the United States, the public health, or the environment” (7 U.S.C. § 7701-7786, 2000). We use the PPQ weed risk assessment (WRA) process (PPQ, 2015) to evaluate the risk potential of plants, including those newly detected in the United States, those proposed for import, and those emerging as weeds elsewhere in the world.
