Haller's pasque flower or Haller's pasque flower ( Pulsatilla halleri ) is a species of pasque flower ( Pulsatilla ) in the buttercup family (Ranunculaceae). It occurs from the Maritime Alps to the Valais as well as in Styria and the Balkan Peninsula, in the Carpathians and in the Crimea.

description

Haller's pasque flower is a perennial herbaceous plant that reaches heights of 5 to 30 centimeters. The upright stem is hairy white shaggy. The basal leaves are not overwintering, but only develop when flowering begins. The 5 to 7 centimeters long, pinnate leaf blade consists of pinnate, pointed-lobed partial leaves. On the top, these are covered by 2 to 4 millimeters long silk hair.

The flowering period extends from May to July. The bracts are fused at their base and slit into linear, silky-haired, shaggy tips. The terminal, single and upright flowers are bell-shaped at the beginning and later spread out. The usually six light to blue-violet, externally hairy bracts are ovate and pointed with a length of 20 to 30 millimeters. The fruits have hairy styluses up to 40 millimeters long in a hairy fruit cluster.

The number of chromosomes is 2n = 32.

Occurrence

Haller's Pasque Flower occurs in the Maritime Alps as far as Wallis and in Styria. Mainly in the subalpine to alpine altitudes , Haller's Pasque Flower thrives at altitudes of up to 3000 meters on calcareous, dry soils , on scree and in crevices. Haller's pasque flower is not common.

Systematics

The first description of Pulsatilla halleri was made in 1809 by Carl Ludwig von Willdenow in Enumeratio Plantarum Horti Botanici Regii Berolinensis: continens descriptiones omnium vegetabilium in horto dicto cultorum , 1, S. 580th

Five subspecies have been described, but they are not recognized as valid by all authors; Here is a list from the previous century (before molecular genetic data could be collected):

  • Pulsatilla halleri subsp. grandis (Wenderoth) Meikle . Many authors put it on Pulsatilla grandis Wenderoth .
  • Pulsatilla halleri Willd. subsp. halleri , occurs in the Alps of France, Italy and Switzerland.
  • Pulsatilla halleri subsp. rhodopaea (Stoj. & Stef.) K. Krause , occurs in Albania, Bulgaria and in the former Yugoslavia. The number of chromosomes is 2n = 32.
  • Pulsatilla halleri subsp. slavica (G. Reuss) Zämelis , occurs in the western Carpathians. The number of chromosomes is 2n = 32.
  • Pulsatilla halleri subsp. styriaca (GAPritzel) Zämelis , occurs in Styria . The number of chromosomes is 2n = 32.
  • Pulsatilla halleri subsp. taurica (Juz.) K. Krause , occurs in the Crimea . The number of chromosomes is 2n = 32.

The subspecies, however, have different distribution areas and so the total distribution area depends on which of the subspecies are classified as separate species or not.

According to various authors, all Pulsatilla species belong to the genus Anemone , which is why there are also the corresponding synonyms ( Anemone halleri All. , Anemone glacialis Clairv. , Anemone hackelii Steud. , Anemone hybrida Miq. Ex Pritz. , Anemone janczewskii Giraudias , Anemone patens Hoppe , Anemone pinnatifida Dulac ).
