“…Most of the species are facultative autogamous. In recent years, they are of interest to European researchers because of their rarity throughout the range, relatively poorly known distribution and taxonomy, erratic temporal appearance that depends mainly on environmental factors, as well as ecology [4][5][6][7][8][9][10][11][12][13][14].…”

Chromosome numbers of selected species of Elatine L. (Elatinaceae)

et al. 2015

The paper reports chromosome numbers for 13 taxa of Elatine L., including all 11 species occurring in Europe, namely E. alsinastrum, E. ambigua, E. brachysperma, E. brochonii, E. californica, E. campylosperma, E. gussonei, E. hexandra, E. hungarica, E. hydropiper, E. macropoda, E. orthosperma, E. triandra originating from 17, field-collected populations. For seven of them (E. ambigua, E. californica, E. campylosperma, E. brachysperma, E. brochonii, E. hungarica, E. orthosperma) the chromosome numbers are reported for the first time. With these records, chromosome numbers for the whole section Elatinella Seub. became available. Although 2n = 36 was reported to be the most common and the lowest chromosome number in the genus, our data show that out of thirteen species analyzed, six had 36 chromosomes but five species had 54 chromosomes, and the lowest number of chromosomes was 18. These data further corroborates that the basic chromosome number in Elatine is x = 9.

“…The best method is calibration of maps in the system, in which they were made, followed by their vectorisation and reduction to a uniform coordinate system. Using this method, data do not lose quality when the map is being scaled up, while a point on it always preserves the specific scale (see also : POPIELA et al 2012b).…”

-The general distribution of the endangered Euro-Siberian sub-Mediterranean species Elatine alsinastrum L. is provided using literature, web-sources and herbaria dataset. The distribution pattern shows some regularities: occurrence of locations along river valleys, formation of concentrated site clusters in some lowlands, wide distances between locations or site clusters or single locations between their clusters. The distribution patterns in central Europe seem to be rather well related to the history of the human migration in Europe at least since the Late Holocene. The scattered locations on the eastern part of the distribution area are likely to be a consequence of missing information, rather than to the fragmentation of its distribution.

“…Their range includes areas with temperate climate on all continents, except Antarctica. The genus Elatine belongs to the family Elatinaceae; however, the origin and taxonomic relations of the family are not fully clarified (Seubert 1845;Niedenzu 1925;Davis and Chase 2004;Popiela et al 2012;Kubitzki 2013).…”

“…The species of the genus are distributed mostly in the northern hemisphere, predominantly in areas with temperate climate. Some species have wide geographical ranges, such as E. alsinastrum and E. hydropiper (Popiela et al 2012;Popiela, Łysko, and Molnár 2013). Others are limited only to Europe, such as E. hexandra and E. hungarica (Takács et al 2013), or are known from very restricted areas, such as Elatine paramoana Schmidt-M. & Bernal (Schmidt-Mumm & Bernal 1995), Elatine ojibwayensis Garneu (Garneu 2006) and Elatine gussonei (Sommier) Brullo Lanfr., Pavone and Ronsisv.…”

Elatine triandra Schkuhr is the most variable and widespread species within the genus Elatine L.; it has been recorded in all continents, except Antarctica, but it is mainly located in Europe. The study is based on an extensive data set of European literature, herbaria and web data that covers the period 1828-2012. The range of the species in Europe is disjunctive, covering the southern and western parts of the Central European Plain and the southern part of the Fennoscandian Shield. At a smaller scale, the species can also be found along some river valleys. In Central Europe many localities, particularly isolated ones in the northern part of the range, are now only historical. From the data set we determined that E. triandra may be best observed between May and October. We found that species records show a near-significant shift since 1828. Depending on the environmental conditions, individuals of the taxon develop as one of two morphs: terrestrial or aquatic. The aquatic morph is characterized by stems, internodes, lamina and petiole that are twice as long as those of the terrestrial form. Elatine triandra seeds show consistent characteristics, both in terms of morphs and populations. Our studies show that the best diagnostic features, in addition to the construction of flowers, are the size, shape and surface structure of seeds. In Central Europe, E. triandra occurs exclusively in communities classified as Isoëto-Nano-Juncetea.

The distibution of Elatine hydropiper L. (Elatinaceae)

Abstract: A distribution map of Elatine hydropiper L. (Elatinaceae), which belongs to the Euro-Siberian phytogeographic element, has been prepared based on literature and web-based data. The distribution range of the taxon, comparison to previous maps and reliability of the results are discussed.
