Summary In the present work number of species recognized in genus Phalaris has been increased to 22. The study includes re-evaluation few taxa with names put into synonymy by previous authors and recognition one new species: lindigii Baldini. examination many herbarium specimens housed 53 Institutions around world basis for defining diversity important taxonomic chorologic implications. Chromosome numbers as P. maderensis (Menezes) Menezes rotgesii (Husn.) Baldini are also reported.

Summary Tragopogon includes two classic examples of recently formed allopolyploid species in North America: T. mirus and miscellus . Older allotetraploids from Eurasia offer ideal taxa for comparing the longer term outcomes allopolyploidy. To help resolve ancestry one these older polyploids, phylogenetic analyses multiple populations allotetraploid castellanus (2 n = 24) its putative diploid parents, crocifolius lamottei , were conducted using sequences nuclear (internal transcribed spacer,...

A synthetic synopsis of the herbaria 16th century is provided. The list in chronological order and resumes general information on earliest from XVI facilitating access by scientific community to this important source historical information. Fifteen are listed, which oldest date back first half century. Nine originated Italy, three Switzerland, two Germany one France. For each herbarium, data provided chronology, geographical origin, format extent, current place conservation, cataloguing...

Plant taxonomists are responsible for, among many other tasks, the formalisation of new taxa, which require publication names for them. According to current version International Code Nomenclature algae, fungi, and plants (Turland & al., 2018—hereafter ICN), either a description or diagnosis is enough valid name. In cases that neither provided, name not validly published (Art. 38 commonly referred as nomen nudum ("naked name"). fact, Art. 38.2 ICN establishes "A taxon statement in opinion...

Tragopogon L. comprises 150 species from Eurasia, with three diploids well established in North America (T. porrifolius, T. dubius, and pratensis). ITS, external transcribed spacer, plastid sequence data indicate that porrifolius is polyphyletic. One lineage phylogenetically separated other collections identified as porrifolius. This widespread Europe, includes the cultivated salsify, has been considered ssp. It distinct having longer ligules an additional set of chromosomal satellites....

Riassunto La revisione tassonomica e l'aggiornamento della flora vascolare dell'isola del Giglio (Arcipelago toscano) sono stati condotti mediante il riesame critico materiale bibliografico disponibile, d'erbario, oltre alla raccolta di nuovi reperti durante periodo 1996–1997. L'elenco floristico è pari a 787 entità, ripartite in 407 generi 103 famiglie. Dell'intera lista (787 entità), la spontanea accertata (pari 700 calcolate escludendo dall'intera 87 entità in: 34 da fonte bibliografica,...

Summary A taxonomic revision of the Italian species Phalaris L. has been carried out. Evidence and information were obtained from study living dried plants, including type material. The attention was focused on vegetative, floral characters, frequently disregarded, chromosome number. 10 have recognized in Italy against 8 reported main italian Floras: P arundinacea L., P. rotgesii (Husnot) Baldini, stat. nov., aquatica hirtiglumis (Trabut) minor Retz., coerulescens Desf., paradoxa truncata...

Summary Tragopogon is a large Eurasian genus of approximately 150 species. Despite the use 6910 aligned bp sequence data representing seven loci, relationships within remain largely unresolved. The young age in combination with rapid diversification may be best explanation for this poor resolution. Our studies have revealed that Geropogon well supported as immediate sister to Tragopogon. Sections Tragopogon, Brevirostris, Chromopappus, and Hebecarpus traditional taxonomic treatments are...

Phalaris L. (Poaceae, canary grasses) is a genus of 20 species found throughout the world with endemic, cosmopolitan, invasive and forage species. A variety features in underscore its importance for study polyploid evolution relation to biodiversity, ecological niche expansion or contraction, endemism, invasiveness. formal comprehensive infrageneric classification lacking. This utilises molecular phylogenetics (nuclear ITS plastid trnT–F regions), morphological (primarily floret structure)...

In the present paper we describe two new endemic species of Anthurium, discovered during field trips to study Araceae flora Chucantí Nature Reserve (Reserva Natural Chucantí) located in province Darién, Panama. Anthurium annularum sp. nov., a member section Xialophyllium, is principally characterized by its hemiepiphytic climbing habit, stems with ring-shaped nodes short internodes alternating much longer internodes, yellow-green spadix and pale green globose berries which are nearly...

Araceae (aroids) is a large and ancient monocot plant family, most notable for its impressive morphological diversity high life-form which also represents group with great economic importance, since many species are used as medicinal, edible ornamental plants. The aroid flora of Central America has about 778 in 26 genera (including three introduced genera). In Panama, several studies, mainly taxonomic (few floristic studies), have contributed to the knowledge country. latest Catalogue...
