description
Vegetative characteristics
The Sardinian buttercup is a deciduous, biennial herbaceous plant and reaches heights of 10 to 30 centimeters. The thick hair ( indument ) of the hollow stem is particularly characteristic .
Generative characteristics
In addition to Ranunculus bulbosus, the Sardinian buttercup is the only Central European buttercup species ( Ranunculus ) with folded-back cup-like tepals , which are half as long as the vivid yellow, petal-like honey leaves .
Chromosome number
It is diploidy and tetraploidy before, the number of chromosomes is 2n = 16, 32 or 48th
ecology
The Sardinian buttercup is a helomorphic therophyte .
The pollination is done by insects or self-pollination. The diaspores spread through the wind or Velcro.
It is a moisture and soil compaction indicator that is also salt bearing.
Occurrence and endangerment
It is widespread in Europe and North Africa and is a neophyte in many areas of the world . The distribution area of the Sardinian buttercup extends in Europe from Spain and Great Britain to Sicily and the Balkan Peninsula , in the east to Ukraine and in the north to southern Sweden .
The Sardinian buttercup colonizes moist to wet fields, short-lived weed meadows , creeping and stepping lawns , damp roadsides and ditches. It thrives on moist, temporarily flooded, nutrient-rich, mostly low-lime, mild to moderately acidic, humus-rich or raw clay soils. He is in Central Europe representative of the Association Myosuro-Ranunculetum sardoi comes but the associations Agropyro-Rumicion, Cynosurion or Aperion also Centunculo-Anthoceretum the Association Nanocyperion and in other societies.
The Sardinian buttercup is safe in Central Europe. In Germany in 1996 it was rated 3 = endangered on the Red List . According to the Federal Species Protection Ordinance (BArtSchV) is "not particularly protected". The elimination of arable land , intensified agriculture and the draining of wet meadows endanger the rough buttercup.
Systematics
Ranunculus sardous was first published in 1763 by Heinrich Johann Nepomuk von Crantz in Stirpium Austriarum Fasciculus , 2, p. 84. A synonym for Ranunculus sardous Crantz is, for example, Ranunculus parvulus L.
Ranunculus sardous occurs in Europe in two subspecies:
- Ranunculus sardous subsp. sardous
- Ranunculus sardous subsp. xatardii (Lapeyr.) Rouy & Fouc.
