Summary[edit]

Description
English: the threadleaf crowfoot or thread-leaved water-crowfoot
Српски / srpski: Srpski naziv

Vlaknasti ljutić, jezerski žabnjak

Opis vrste

Višegodišnja biljka stajaćih ili sporo tekućih voda bogatih nutrijentima. Liči na barski ljutić (Ranunculus aquatilis), sa razlikom da ne obrazuje plutajuće listove. Kao i prethodna ima suvozemnu i emerznu varijantu – tom vrstom prilagodljivosti u stanju je da preživi nagla isušenja plitkih, toplih periodičnih voda u kojima živi. Izdanci su dugi 10-15 cm. Listovi cirkularno fino perasti, donji sa drškama, dok forma na suvom obrazuje rigidne, zbijene listove radi čuvanja vlage. Cvetovi su sitni, promera svega 7-12 mm, cveta od aprila do kraja jula. Široko rasprostranjena cirkumpolarna vrsta, borealni florni element, nalazimo ga u barama, jezerima, kubicima i forlandima reka od 0 do 3600 m nmv. Nije naročito probirljiv po pitanju sastava vode, ali se najčešće javlja u mezotrofnom i eutrofnom okruženju. Čest u Sredozemnom području i na Primorju. U Srbiji u višim područjima pod mediteranskim uticajem i u nizinama.

Sin. Ranunculus paucistamineus Tausch, Batrachium trichophyllum (Chaix) Bosch, Batrachium divaricatum (Schrank) Schur, Batrachium diversifolium Min.
