Also, the paper provides information about the hayfields floral richness, a great scientific value for Romania and Europe. The study of the flora was carried out in several stages: 2005-2008, 2013, 2017-2018. In the studied area, 397 taxa were identified, distributed in 82 families with therapeutic potential, represented by 164 medical taxa, 37 of them being in the European Pharmacopoeia 8.5. The study reveals that most plants contain: volatile oils (13.41%), tannins (12.19%), flavonoids (9.75%), mucilages (8.53%) etc. This plants can be used in the treatment of various human disorders: disorders of the digestive system, respiratory system, skin disorders, muscular and skeletal systems, genitourinary system, in gynaecological disorders, cardiovascular, and central nervous sistem disorders.

The Correct Generic Names for Sonchus Webbii Sch.Bip. and Prenanthes Péndula Sch.Bip

DAVID BRAMWELL Jardín Botánico Canario «Viera y Clavijo», Apdo. 14 de Tafira Alta. 35017 Las Palmas de Gran Cana ria, islas Canarias, España. Recibido: febrero 2000 Key words.' Lactucosonchus, Chrysoprenanthes, Sonchus, Prenanthes, Canary Islands. Palabras clave: Lactucosonchus, Chrysoprenanthes, Sonchus, Prenanthes, islas Canarias. SUMIVIARY The correct ñames for two Cañarían Compositae, Sonchus webbii and Prenanthes péndula are dis- cussed in the light of recent publications.The ñame Lactucosonchus webbii is considered to be the correct ñame for the former taxon and the latter is transferred to the genus Chrysoprenanthes. RESUIVIEN Se comenta los nombres correctos de dos compuestas Canarias, Sonchus webbii y Prenanthes péndula en vistas de recientes publicaciones. Se considera como nombre correcto para la primera especie Lactucosonchus webbii y se transfiere la segunda al genero Chrysoprenanthes. INTRODUCTION Two recent publications, REIFENBERGER & REIFENBERGER (1997) and SENNIKOV & ILLARIONOVA (1999) have established a new genus Wildpretia and a new section of the genus Sonchus, sect. Chrysoprenanthes. For different reasons which are discussed below each of these new ñames is considered to be unnecessary. In the first case there already exists a validly published ñame Lactucosonchus (Sch. Bip.) Svent. with priority over Wildpretia Reifenberger and in the second case, molecular studies show that Prenanthes péndula Sch. Bip., though not a true member of the ISSN 0211-7150 180 DAVID BRAMWELL genus Prenanthes is also not a Sonchus as it forms a sister dade to Sonchus along with Sventenia and Babcockia.

Genetic Variability and Distance Between Lactuca Serriola L
Acta Bot. Croat. 77 (2), 172–180, 2018 CODEN: ABCRA 25 DOI: 10.2478/botcro-2018-0019 ISSN 0365-0588 eISSN 1847-8476 Genetic variability and distance between Lactuca serriola L. populations from Sweden and Slovenia assessed by SSR and AFLP markers Michaela Jemelková1, Miloslav Kitner1, Eva Křístková1, Ivana Doležalová2, Aleš Lebeda1* 1 Palacký University in Olomouc, Faculty of Science, Department of Botany, Šlechtitelů 27, 783 71 Olomouc, Czech Republic 2 Department of Genetic Resources for Vegetables, Medicinal, and Special Plants of Crop Research Institute in Olomouc, Šlechtitelů 29, 783 71 Olomouc, Czech Republic Abstract – The study involved 121 samples of the common weed, Lactuca serriola L. (prickly lettuce), represent- ing 53 populations from Sweden and Slovenia. The seed materials, originating from different habitats, were re- generated and taxonomically validated at the Department of Botany, Palacký University in Olomouc, Czech Re- public. The morphological characterizations of the collected plant materials classified all 121 samples as L. serriola f. serriola; one sample was heterogeneous, and also present was L. serriola f. integrifolia. Differences in the amount and distribution of the genetic variations between the two regions were analyzed using 257 ampli- fied fragment length polymorphism (AFLP) and 7 microsatellite (SSRs) markers. Bayesian clustering and Neigh- bor-Network were used for visualization of the differences among the samples by country. Under the Bayesian approach, the best partitioning (according to the most frequent signals) was resolved into three groups. While the absence of an admixture or low admixture was detected in the Slovenian samples, and the majority of the Swedish samples, a significant admixture was detected in the profiles of five Swedish samples collected near Malmö, which bore unique morphological features of their rosette leaves.

Germination and Emergence of Prickly Lettuce (Lactuca Serriola L.) and Its Susceptibility to Selected Herbicides
Germination and emergence of prickly lettuce (Lactuca serriola L.) and its susceptibility to selected herbicides J. Mikulka, D. Chodová Research Institute of Crop Production, Prague-Ruzyně, Czech Republic ABSTRACT Three-year trials were conducted to study germination and emergence of prickly lettuce (Lactuca serriola L.) achenes, increments of shoot dry matter and susceptibility of the weed to selected herbicides. The germination rates of achenes at 10°C (92%), 20°C (97%) and 30°C (95%) did not indicate any significant differences within 20 days from sowing. The highest percentage emergence of prickly lettuce achenes was determined after their sowing into a depth of 1 mm. Differ- ences from the variants of sowing onto the soil surface (0 mm), into a depth of 10 and 20 mm were significant. There were no differences in the emergence rates from a depth of 10 and 20 mm. The highest increments of shoot dry matter were observed when prickly lettuce plants were grown for 4–7 weeks after sowing at 20°C. The effect of selected herbi- cides on prickly lettuce plants treated at the stage of 2–3 true leaves was evaluated on the basis of a change in the content of shoot dry matter. A significant decrease in dry matter against the control was recorded in all variants after herbicide application. The effect (expressed by a lower dry matter content) was significantly higher after the combination ami- dosulfuron + iodosulfuron-methyl + mefenpyr-diethyl (10 + 2.5 + 25 g/ha) was used than after the application of tribe- nuron (10.85 g/ha) and picolinafen + cyanazine (120 g + 480 h).

Most members of the alliance are endemic to the oceanic archipelagos in the phytogeographic region of Macaronesia. They display extensive morphological, ecological, and anatomical diversity, likely caused by the diverse habitats on islands and rapid adaptive radiation. As a premier example of adaptive radiation and insular woodiness of species endemic to oceanic islands, the alliance has been the subject of intensive evolutionary studies. While phylogenetic studies suggested that it is monophyletic and its major lineages radiated rapidly early in the evolutionary history of this group, genetic mechanisms of speciation and genomic evolution within the alliance remain to be investigated. We ﬁrst attempted to address chloroplast (cp) genome evolution by conducting comparative genomic analysis of three representative endemic species (Sonchus acaulis, Sonchus canariensis, and Sonchus webbii) from the Canary Islands.

Mihail Sadoveanu, nr. 3, 700490–Iaşi, Romania Corresponding author: [email protected] This second part of the paper about the vascular flora of Rarău Massif listed approximately half of the whole number of the species registered by the authors in their field trips or already included in literature on the same area. Other taxa have been added to the initial list of plants, so that, the total number of taxa registered by the authors in Rarău Massif amount to 1443 taxa (1133 species and 310 subspecies, varieties and forms). There was signaled out the alien taxa on the surveyed area (18 species) and those dubious presence of some taxa for the same area (17 species). Also, there were listed all the vascular plants, protected by various laws or regulations, both internal or international, existing in Rarău (i.e. 189 taxa). Finally, there has been assessed the degree of wild flora conservation, using several indicators introduced in literature by Nowak, as they are: conservation indicator (C), threat conservation indicator) (CK), sozophytisation indicator (W), and conservation effectiveness indicator (E). Key words: Vascular flora, Rarău Massif, Romania, conservation indicators. 1. INTRODUCTION A comprehensive analysis of Rarău flora, in terms of plant diversity, taxonomic structure, biological, ecological and phytogeographic characteristics, as well as in terms of the richness in endemics, relict or threatened plant species was published in our previous note (see Oprea & Sîrbu 2012).
