Roz\u0161\u00edrenie:<\/strong> Druh s euro\u00e1zijsk\u00fdm, kontinent\u00e1lnym are\u00e1lom. Roz\u0161\u00edrenie siaha od Kazachstanu po Ukrajinu, \u010falej na z\u00e1pad vyznieva v Pan\u00f3nii. Hojnej\u0161\u00ed v\u00fdskyt je len vo Ve\u013ekej Uhorskej n\u00ed\u017eine v z\u00e1padnej polovici Ma\u010farska, v srbskej Vojvodine je v\u00fdskyt obmedzen\u00fd na tri lokality, nieko\u013eko je zn\u00e1mych z Rumunska.
\nV \u010ceskej republike nerastie. Na Slovensku, kadia\u013e prech\u00e1dza severoz\u00e1padn\u00e1 hranica are\u00e1lu, bol historicky dolo\u017een\u00fd z jednej lokality v Podunajskej n\u00ed\u017eine. Od roku 1931 je tu nezvestn\u00fd. Z V\u00fdchodoslovenskej n\u00ed\u017einy bol potvrden\u00fd z piatich lokal\u00edt, posledn\u00e9 publikovan\u00e9 \u00fadaje s\u00fa z roku 1965. S odstupom viac ako polstoro\u010dia bol op\u00e4tovne n\u00e1jden\u00fd na dvoch nov\u00fdch lokalit\u00e1ch, odkia\u013e dosia\u013e nebol zn\u00e1my. <\/p>\n

Ekol\u00f3gia:<\/strong> Iskern\u00edk mnoholist\u00fd sa vyskytuje v tepl\u00fdch n\u00ed\u017ein\u00e1ch, na vlhk\u00fdch, periodicky na jar zaplavovan\u00fdch miestach, v lete vysychaj\u00facich (ale nemusia), v depresi\u00e1ch, priekop\u00e1ch, \u010dasto na mierne zasolen\u00fdch bahnit\u00fdch p\u00f4dach. Obsadzuje aj silne antropicky ovplyvnen\u00e9 biotopy ako depresie uprostred pol\u00ed. Kvitne v m\u00e1ji a\u017e j\u00fali.<\/p>\n

Opis:<\/strong> Jednoro\u010dn\u00e1 rastlina vysok\u00e1 10\u201320 cm, dvojtv\u00e1rna. Ponoren\u00e1 forma m\u00e1 byle vzpl\u00fdvav\u00e9 s pazu\u0161n\u00fdmi, rozkon\u00e1ren\u00fdmi stopkami, listy v tvare ni\u0165ovit\u00fdch praslenov\u00fdch segmentov ponoren\u00e9, vzpl\u00fdvaj\u00face, obr\u00e1tene vajcovit\u00e9 a\u017e kopijovit\u00e9, niekedy s tromi zubmi, pozemn\u00e1 forma na obna\u017eenom bahne, byle priame, pr\u00edzemn\u00e9 listy v ru\u017eici, \u010depele obr\u00e1tene vajcovit\u00e9, celistvookrajov\u00e9 a\u017e 3-lalo\u010dn\u00e9, 5\u201310 mm, by\u013eov\u00e9 listy kopijovit\u00e9, celistvookrajov\u00e9, kvety hrubo stopkat\u00e9, drobn\u00e9, 3\u20136 mm v priemere, koruna \u017elt\u00e1, plodstvo gu\u013eat\u00e9, na\u017eky jemne bradavi\u010dnat\u00e9, zob\u00e1\u010dik tak\u00fd dlh\u00fd ako 1\/2 na\u017eky. <\/p>\n

Ohrozenie a ochrana:<\/strong> Ide o ve\u013emi ohrozen\u00fd druh. Historick\u00e9 lokality zanikli rozsiahlymi meliora\u010dn\u00fdmi \u00fapravami na V\u00fdchodoslovenskej n\u00ed\u017eine, rozor\u00e1van\u00edm alebo vysu\u0161ovan\u00edm a intenzifik\u00e1ciou pasienkov. V klimaticky priazniv\u00fdch rokoch (hojnos\u0165 jarn\u00fdch zr\u00e1\u017eok) sa vyskytuje \u010dastej\u0161ie, v s\u00fa\u010dasnosti n\u00e1jden\u00fd na sekund\u00e1rnych stanovi\u0161tiach, v periodicky zaplavovan\u00fdch depresi\u00e1ch na poliach a na extenz\u00edvne pasen\u00fdch striedavo vlhk\u00fdch pasienkoch. Na Slovensku je zaraden\u00fd medzi z\u00e1konom chr\u00e1nen\u00e9 (\u00a7)<\/a>, kriticky ohrozen\u00e9 druhy (CR)<\/a>. Chr\u00e1nen\u00fd tie\u017e v Ma\u010farsku<\/a>.<\/p>\n

Pozn\u00e1mka:<\/strong> V celej Pan\u00f3nii na z\u00e1padnej hranici are\u00e1lu silne ustupuj\u00faci, ohrozen\u00fd druh.<\/p>\n
