Article
In this research the family Cyperaceae in Ukraine has critically been revised. An up-to-date classification of all taxa is presented, i.e. one subfamily (Cyperoideae), 13 tribes, 16 genera, and 148 species. The genus Cyperus s.l. includes now Acorellus, Dichostylis, Juncellus, Mariscus, Pycreus, and Torulinium, which were previously considered as separate genera. However, the genera Schoenoplectus and Schoenoplectiella are listed by us as recognised taxa. A new combination in the rank of section, Hostianae (Carex: Cariceae), is given. The basic unit of our classification is the species, although subspecies and varieties are indicated to cover intraspecific heterogeneity when necessary.

We present the third edition of the complete catalogue of the alien flora of the Czech Republic, which follows the 2002 and 2012 editions. It has been updated by incorporating new data collected over the last decade and reassessing the current status of taxa based on improved taxonomic and ecological knowledge. All changes in the taxon listing from the 2012 version are documented and explained in an appendix. Based on comprehensive data sources, including the recently developed Pladias Database of the Czech Flora and Vegetation and the Archaeobotanical Database of the Czech Republic, we list 1576 taxa alien to this country, with information on their taxonomic position, life form, geographic origin, residence time category (archaeophyte or neophyte), invasion status (casual, naturalized or invasive), date of the first and last field record, grid-cell occupancy, pathway of introduction into the country, habitat affiliation and impact assessment. This edition includes 122 more taxa than the 2012 edition; 157 taxa were added and 35 were removed. Of the removed taxa, 17 were reclassified as native, eight were removed due to lack of evidence of the occurrence in the wild, records of six taxa were assessed as doubtful, and four are not taxonomically justified. The alien flora is recruited from 630 genera and 122 families, and comprises 385 archaeophytes and 1191 neophytes; most taxa are casual (1084, i.e. 68.8% of the total number), 417 taxa are naturalized (26.4%), and 75 are invasive (4.8%). The proportion of invasive taxa is almost equal for archaeophytes and neophytes (4.7% and 4.8%, respectively), casual taxa are over-represented among neophytes, and naturalized taxa among archaeophytes. The contribution of alien taxa to the Czech flora is 37.8% if all aliens are considered or 16.2% if only naturalized taxa (including invasives), which are a permanent part of the flora, are included. For all groups of invasion status, the numbers of taxa are increasing over time with no sign of deceleration. Most alien plants originate from the Mediterranean region (618 taxa, i.e. 31.5%), other parts of Europe (380 taxa, 19.4%), other parts of Asia (290 taxa, 14.1%) and North America (262 taxa, 13.4%). The highest number of invasive taxa (27, corresponding to 27.6% of all invasive archaeophytes and neophytes) are from North America. Occupancy of grid cells of 10 × 6 arc-minutes significantly increases with invasion status and residence time. Invasive taxa are present in more grid cells than naturalized and casual, and archaeophytes occupy on average more grid cells than neophytes in each invasion status category. Maps based on the cumulative record of alien species occurrence over the past 50 years, expressed as the proportion of the entire flora, show that alien species are relatively more prevalent in lowlands and large urban agglomerations. In a European comparison, the Czech Republic is currently a moderately invaded country.
... Distribution and habitat. Cyperus sesquiflorus is a pantropical species (Tucker, 1984;Verloove, 2014;Govaerts et al., 2021). It is very common throughout the Central-West region of Brazil, growing in dry to moist open soil, mainly in disturbed areas such as gardens, roadsides, and pastures. ...

A taxonomic study of Cyperus L. (Cyperaceae) in the Central-West region of Brazil is presented. We examined more than 1300 herbarium specimens. Many of the species were also studied in the field. Our results recognize 59 species of Cyperus in the Central-West of Brazil, including three species endemic to the country that are potentially threatened with extinction, i.e., C. hooperae G. C. Tucker, C. longiculmis Pereira-Silva, Hefler & R. Trevis., and C. tuckerianus Pereira-Silva, Hefler & R. Trevis. Cyperus oxylepis Nees ex Steud. is reported from Brazil for the first time. Cyperus incomtus Kunth var. miguelii Kük. is proposed as a synonym of C. pearcei C. B. Clarke. We designate lectotypes for 20 names, a neotype for C. oxylepis, and an epitype for C. surinamensis Rottb. and select second-step lectotypes for 10 names. We also provide detailed morphological descriptions, illustrations, distribution data, an identification key for all species, and assessments of the conservation status for most species.
... It has been mentioned by Viney (1996) but no data on specimens have ever been published. Nomenclature and taxonomy follow the treatment by Verloove (2014) in which details on naturalisation in the Mediterranean region can be found. To be classified as 'Casual' in Cyprus. ...

This paper deals with specimen-based records of 20 taxa, the majority of which are alien species in Cyprus. The following taxa are new to Cyprus or have been documented by specimens for the first time: Allium tuberosum, Amaranthus emarginatus subsp. pseudogracilis, A. powellii, Commelina communis, Cyperus alternifolius subsp. flabelliformis, Helianthus annuus, Lantana camara, Leucaena leucocephala subsp. leucoce-phala, Phoenix dactylifera, Urochloa ramosa, Washingtonia filifera and Zea mays. Namely Leucaena leucocephala should be given particular consideration because it may soon become a problematic invasive.
... Furthermore; Dobignard & Chatelain (2010-2020 in their synonymous and bibliographic index of the North African flora cite this species as a neophyte for Azores and Canary Islands, confirmed by Verloove (2014). We also referred to the website of the herbarium of the botanist researcher Gérard De Bélair (http://gdebelair.com/tax/ ...

This study provides a definition and description of Cyperus eragrostis as a new alien species to Algeria and North African flora. This hemicryptophyte, native to the tropical parts of South America, is recorded for the first time in Jijel eco-complex wetlands in NorthEast Algeria. Applying the standard phytosociological method we studied the stands in which this alien species grows together with other hygrophilous and ruderal species. The present study improves the knowledge of the Algerian flora and completes the information about the distribution of C. eragrostis reported by the available international literature and public herbaria. Izvleček V raziskavi smo opisali vrsto Cyperus eragrostis kot novo tujerodno vrsto v flori Alžirije in severne Afrike. To hemikriptofitsko vrsto, ki je domorodna v tropskih predelih Južne Amerike, smo prvič zabležili v mokrišču Jijel v severovzhodni Alžiriji. Sestoje, v katerih uspeva ta tujerodna vrsta skupaj z ostalimi higrofilnimi in ruderalnimi vrstami, smo preučili s standardno fitocenološko metodo. Naša raziskava dopolnjuje znanje o flori Alžirije in izboljšuje poznavanje razširjenosti vrste C. eragrostis, ki je na voljo v mednarodni literaturi in javno dostopnih herbarijih.
... It was initially introduced as a gardening plant in the middle of the 19th century. Its invasion history and distribution were summarized by Petřík (2003) and Verloove (2006). At present, C. eragrostis occurs in many countries in South, West and Central Europe and partly also in the Balkan Peninsula (Verloove 2014;Verloove & al. 2014;Stoyanov & Barzov 2018). ...

The South American weed Cyperus eragrostis Lam. (Cyperaceae) is reported for the first time in the wild from Tunisia, North Africa. A brief description of the species is given and it is illustrated in its Tunisian habitat. Its actual distribution is presented and discriminatory characteristics as compared to C. flavescens, a native species with which it has been confused for some time, are commented.
... General distribution: C. odoratus is a pantropic species which has been naturalized in Europe (Spain, Italy, Serbia, Bulgaria and Romania) (Verloove, 2014). Distribution in Serbia: For a long time, C. odoratus has been confused with C. strigosus and other species from the Cyperus genus, so its exact naturalization history in Serbia is not known. ...
... Distribution in Serbia: For a long time, C. odoratus has been confused with C. strigosus and other species from the Cyperus genus, so its exact naturalization history in Serbia is not known. After the revision of herbarium specimens deposited in BEOU, Verloove (2014) concluded that the first record of C. odoratus, under the erroneous binomial C. strigosus, was published at the beginning of the 21st century by Stevanović et al. (2004Stevanović et al. ( , 2005. It refers to Mali Lap marsh situated near the village of Dubovac (Banat region -EQ15) (Fig. 7). ...

This paper presents the distribution of nine endangered, rare or potentially invasive plant species present in the Serbian flora, based on field investigations, literature and herbarium data. The chorology of the following vascular plants: Ranunculus lateriflorus, Elatine alsinastrum, Sedum stefco, Galium boreale, Ornithogalum narbonense, Cyperus serotinus, Cyperus odoratus, Typha laxmannii and Typha shuttleworthii, is shown on 10 x 10 km 2 UTM maps. The data on the distribution of these endangered and rare species provide a valuable base for estimating and revising their threatened status in Serbia, as well as for conducting adequate conservation measures with regard to their habitats. Chorological data on the Cyperus odoratus species in Serbia are significant for getting to know its naturalization history and spreading pathways in both Serbia and its neighbouring countries.
... and Pančevo (Perić & Rilak 2017). According to Verloove (2014) earlier records of C. strigosus from Bulgaria and Serbia are erroneous and refer to C. odoratus. Our field investigations confirm identity of this species in Serbia as C. odoratus and its further spread to the west. ...

The paper propose nine new nomenclature combinations and indicate eight new synonyms. There are 12 taxa (species and subspecies) of vascular flora which are new for the flora of Serbia (of which nine are autochthonous and three allochtonous plants). An old or unreliable literature records for three autochthonous and one allochthonous plant in the flora of Serbia has been confirmed. Eight plant taxa are a novelty for proper Serbia, Vojvodina, or Kosovo and Metohija, and for three plants, presence in certain administrative units in Serbia has been proved. The last part of the paper contains information on eight taxa whose presence in Serbia or in its territorial units has been refuted.
