The plant is amphibious. Up to two meters long sprout axes are formed in deep water. The land shape is very low. The floating leaves are serrated deeply, kidney -shaped (occasionally missing; sometimes irregularly shaped transition sheets), the triangular side sheets are overgrown with three quarters or more of their length with the leaf stick. The dive blades are cutter/gab -colored (always available).

blossoms [ Edit | Edit the source text ]

The radial symmetrical flowers are hermaphrodite. The five white, durable crown leaves are yellow and 5 to 10 millimeters long. The nectar glands are around to cup -shaped. There are 14 to 22 stamens per flower. The heyday is from April to September.

Usually 32 to 36 (extreme: 21 to 49) are initially formed hairy, later partially balancing nuts per flower. The fruit stick is shorter than the stem of the opposite swimming sheet.

Chromosomenzahl [ Edit | Edit the source text ]

The species is hexaploid with a number of chromosomes of 2n = 48 [first] .

Like all Ranunculus -The ordinary water hewing foot is poisonous.

The species has occurrence in swimming blade companies standing or slowly flowing, mostly base-rich, meso to eutrophic, muddy but not heavily stressed waters, especially trenches, also in ponds and pools. The distribution in Central Europe is insufficiently known because it is a stimulus -critical clan (see below). Unlike the name “Ordinary Water Hahn Foot”, the species is rather scattered and, for example, occurs far less frequently than the similar shield water hole foot or the brush-leafed water tap foot. In the more water-rich lowlands there are naturally more locations than in the hill and mountain country. The species is a character plant of order Potamogetonetalia and occurs especially in companies of the Nymphaeion Association. [2] It thrives up to a water depth of 1 to 1.5 meters. [3] The species rises in the Himalayas up to a sea level of 5100 meters. [3]

The ecological pointer values ​​according to Landolt et al. 2010 are in Switzerland: Number of moisture F = 5V (under water), light number L = 4 (light), response number R = 4 (neutral to basic), temperature number T = 4 (collin), nutrient number N = 2 (nutrient low), continental number K = 2 (subocean). [4]

There are several, sometimes very similar white -flowering Ranunculus -Tarten with occurrence in water. In addition, numerous bastards between these can lead to the complete use of the species limits. In particular, it is very similar:

Water hole foot ( Aquatic ranunculus Agg.; Note: no determination up to the species level)
  • Shield water hole foot ( Ranunculus peltatus Wardrobe ),
    With the subspecies Ranunculus peltatus subsp. peltatus , Ranunculus peltatus subsp. BAUDOTII (Godr.) Meikle ex C.D.K.Cook (Salt water tap foot), Ranunculus peltatus subsp. fucoides (Freyn) Muñoz Garm. and Ranunculus peltatus subsp. Sphaerospermus ;

But also the species:

further:

Because of the determination problem, a summary of the species is often carried out in floristic atlases Aquatic ranunculus , Ranunculus ololeucos , Ranunculus peltatus , Ranunculus brushing and Ranunculus trichophyllus To a type of collecting ” Aquatic ranunculus agg. “(Agg. = Agregate) – This must not be used with the species with regard to the distribution and frequency Aquatic ranunculus S.str. ”can be confused or equated.

Due to the determination problem, there is a variety of synonyms for this type:

The ordinary water hewing foot is rarely used as an ornamental plant for garden ponds. The species has been in culture at least since 1789. [5]
