Dracocephalum ruyschiana (Lamiaceae): first record for Spain

Abstract

Dracocephalum ruyschiana L. is an Eurasian continental species with a fragmented distribution extending from the boreal regions to the Asian steppes and European mountains. In the Pyrenees it is only known from three locations in France, but two of them have not been rediscovered in modern times, and there are no citations in Spain or Andorra. In summer 2021 a population was found in the Val d’Aran (Catalan Pyrenees, Spain). A complete description is presented, and an identification key is included as an amendment for their taxonomic treatment in Flora iberica. Its current Pyrenean distribution, habitat and phenology are also reported. The conservation status is evaluated under the IUCN regional and national levels.
