The number of chromosomes is 2n = 40 or 80.

Occurrence

The distribution area of Senecio doronicum ranges from southern, south-eastern to central Europe. This lime-loving plant occurs on stony lawns , rocky slopes and in the so-called Krummholzzone at altitudes of 1200 to 2500 meters. There are only scattered occurrences in the German Alps. In the Allgäu Alps, it rises at altitudes from 1400 meters at the Bacherloch in Bavaria to 2350 meters in the Tyrolean part on the west ridge of the Biberkopf . It is a characteristic species of Seslerio-Caricetum sempervirentis, but also comes in companies of Festucion variae ago. It is widespread in Switzerland and Austria in all alpine regions.

Systematics and distribution

The first publication took place in 1753 under the name ( Basionym ) Solidago doronicum by Carl von Linné . The new combination to Senecio doronicum (L.) L. was published in 1759 by Carl von Linné. Other synonyms for Senecio doronicum (L.) L. are: Senecio longipetalus Sennen , Senecio rotundifolius Lapeyr. non stokes .

One can distinguish the following subspecies:

  • Senecio doronicum (L.) L. subsp. doronicum
  • Senecio doronicum subsp. longifolius (Willk.) J. Calvo (Syn .: Senecio doronicum var. longifolius Willk. ): It occurs in Spain , France and Switzerland .
  • Senecio doronicum subsp. orientalis J. Calvo (Syn .: Senecio orientalis Ten. non Willd. ): The distribution area includes Germany , Austria , Italy and the former Yugoslavia .
  • Senecio doronicum subsp. transylvanicus (Boiss.) Nyman (Syn .: Senecio transylvanicus Boiss. , Senecio glaberrimus (Rochel) Simonk. non DC. , Senecio doronicum subsp. glaberrimus (Rochel) Kožuharov & N.Andreev ): It comes in Bulgaria , Romania and Macedonia before .

Depending on the author, the following can no longer be classified as a subspecies of Senecio doronicum :

  • Senecio doronicum subsp. lagascanus (DC.) Vigo => Senecio lagascanus DC.
  • Senecio doronicum subsp. lusitanicus Cout. => Senecio lusitanicus (Cout.) Pérez-Romero
  • Senecio doronicum subsp. corbariensis (Timb.-Lagr.) B. Bock and Senecio doronicum subsp. gerardi (Godr. & Gren.) Nyman => Senecio provincialis (L.) Druce
  • Senecio doronicum subsp. ruthenensis (Mazuc & Timb.-Lagr.) Nyman => Senecio ruthenensis Mazuc & Timb.-Lagr.
