Publication due Feruary 2018

  • Volume 20 in the Collection: Monographs of Iberian Botany.
  • The first monograph for Spain of the two complex genera Hieracium and Pilosella. It uses dichotomous keys illustrated with photos of fresh material, as well as detailed descriptions, ecology, chorology and observations of taxonomic and nomenclatural type.

    All the genera with anomalous reproduction are very complicated to reduce to typical species and any other type of infragenérico or infraspecific taxon. Surely in Hieracium and Pilosella this difficulty reaches its maximum degree, given its enormous variability, the so nuanced environments that colonize and the facility to generate intermediate strains between the sections further away from each other.
    The methodological classification is that of Nägeli & Peter extended by Zahn, without giving the hybrid treatment to any of the recognized taxa. Its lack of use is not a negation of the hybrid character, but the uncertainty when distinguishing two situations morphologically as similar as hybrids and hybrid species kept apomictically. In addition, we will always indicate parents for all possible hybrids or consolidated species of hybrid origin.

    The treatment of these genera in Flora iberica was written by the same authors. However, there are substantial differnces with this monograph where the treatment is more detailed and uses much broader identification characteristics, with more species considered (340 Hieracium and 72 Pilosella ). Flora iberica is a general work where only keys are provided for essential species about a fifth of those covered in this work.
