A note on Pteris vittata L. (Pteridaceae) in Montenegro
Pteris vittata, formerly doubtfully indicated for Dalmatia, is recorded for Montenegro based on a hitherto disregarded collection preserved in the Vienna University herbarium
Die Ranunculaceae der Flora von Zentraleuropa: Ficaria
Schon sehr frĂŒh wurde die Verwandtschaft um Ficaria verna [Ranunculus ficaria] wegen einer Reihe morphologischer Besonderheiten (ein einzelnes, apikal gekerbtes Keimblatt, meist nur 3 Ă€uĂere, aber vermehrte innere BlĂŒtenhĂŒllblĂ€tter, Wurzelknollen) als Satellitengattung von der formenreichen Gattung Ranunculus abgetrennt, bei einer Vereinigung mit ihr aber zumindest als eigene Sektion hervorgehoben. JĂŒngste, auf molekular-genetischen Analysen von Kern- und Chloroplasten-Gensequenzen beruhende, phylogenetische Untersuchungen bekrĂ€ftigen die Separierung als eigene, monophyletische Gattung, die am engsten mit Coptidium (mit ebenfalls 3-zĂ€hligem Kelch) als eher basaler Gattung der Ranunculeae und nicht unmittelbar mit Ranunculus verwandt ist
Nomenklatorische Korrektur einiger Syntaxon-Namen
Nomenklatorische Korrekturen (nach dem Artikel 43 des Codes der pflanzensoziologischen Nomenklatur) einiger Syntaxon-Namen aus den Klassen Bidentetea tripartiti, Festuco-Brometea, Koelerio-Corynephoretea and Puccinellio-Salicornietea, die wegen falsch angewandter Artnamen notwendig waren, werden begrĂŒndet und durchgefĂŒhrt. Die Problematik des Namens Agropyro dumetori-Artemisietum absinthii Br.-Bl. ex Kielhauser 1954 nom. invers. wird erörtert. FĂŒr einige der Namen wird die noch ausstehende Typisierung vorgenommen.Ten syntaxa names (belonging to the classes of Bidentetea tripartiti, Festuco-Brometea, Koelerio-Corynephoretea and Puccinellio-Salicornietea) were corrected in accordance with the Code of Phytosociological Nomenclature (Art. 43), resulting from a critical evaluation of several misapplied species names. The problems with the name Agropyro dumetori-Artemisietum absinthii Br.-Bl. ex Kielhauser 1954 nom. inv. were discussed
Notes sur le genre <i>Echinops</i> (Asteraceae) en Europe du Sud-Est
Echinops siculus Strobl, jusquâalors considĂ©rĂ©e comme endĂ©mique dâItalie, a Ă©tĂ© signalĂ©e pour la premiĂšre fois dans la pĂ©ninsule balkanique Ă partir dâindividus rĂ©coltĂ©s Ă Corfou (GrĂšce). Les similaritĂ©s morphologiques avec dâautres taxa dâEchinops L. connus en GrĂšce sont briĂšvement discutĂ©es. Echinops albidus Boiss. & Spruner est exclu dâItalie, E. spinosissimus Turra subsp. neumayeri (Vis.) KoĆŸuharov est confirmĂ© pour lâAlbanie. Des notes complĂ©mentaires concernant la prĂ©sence de ces trois espĂšces sur les Ăźles ioniennes sont proposĂ©es. Les noms de trois taxa sont lectotypifiĂ©s.The occurrence of Echinops siculus Strobl, previously considered endemic to Italy, is for the first time reported from the Balkan Peninsula based on plants collected in Corfu (Greece). Morphological similarities with other taxa of Echinops L. recorded in Greece are briefly discussed. Presence of Echinops albidus Boiss. & Spruner is excluded from Italy, E. spinosissimus Turra subsp. neumayeri (Vis.) KoĆŸuharov is confirmed for Albania. Further notes concerning the occurrence of these three species on the Ionian Islands are provided. The names of the three taxa are lectotypified.</p
Taxonomy and nomenclature of the polymorphic European high mountain species Androsace vitaliana (L.) Lapeyr. (Primulaceae)
Androsace vitaliana (syn. Vitaliana primuliflora; Primulaceae) has been subject to several taxonomic treatments, whose conclusions ranged from a single species with numerous infraspecific taxa to several species usually without infraspecific taxa. Here, following molecular investigation, several taxonomic changes are made. A single species with the following infraspecific taxa is recognized: subsp. vitaliana (Pyrenees), subsp. cinerea (south-western Alps), subsp. lepontina (Pennine Alps), subsp. sesleri (south-eastern Alps), subsp. praetutiana (Apennines) and subsp. assoana (Iberian Peninsula excluding the Pyrenees), the last of which is divided into the four allopatrically distributed varieties assoana, centriberica, flosjugorum and nevadensis. Contrary to some previous assertions, all taxa are allopatric and, especially for subspp. vitaliana, cinerea and lepontina, where clear diagnostic characters are lacking, they can best be determined by their geographic origin
