Synonyms[6]
  • Spitzelia Sch.Bip.[7]
  • Medicusia Moench[8]
  • Hagioseris Boiss.[9]
  • Deckera Sch.Bip.[10]

Picris species are used as food plants by the larvae of some Lepidoptera species, such as the grass moth Diasemia reticularis. Schinia cardui feeds exclusively on P. hieracioides.

The genus is widespread across Europe, Asia, Africa, and Australia.[11][12][13]

Etymology

edit

Picris is from the Greek picros meaning 'bitter', in reference to the bitter taste of some species in the genus.[14][[#cite_note-FOOTNOTEBrittonBrown1913==Description==_Erect_annual_to_perennial_taprooted_herbs,_mostly_branching,_stem_and_leaves_bearing_stiff_bristly_hairs,_with_rather_large,_usually_[[corymbose]]_or_[[paniculate]]_heads_of_yellow_flowers.'"`UNIQ--ref-00000013-QINU`"''"`UNIQ--ref-00000014-QINU`"'_==Taxonomy==_===Taxonomic_history===_The_genus_''Picris''_was_first_validly_described_by_[[Carl_Linnaeus|Linnaeus]]_in_1753'"`UNIQ--ref-00000015-QINU`"'_with_the_genus_being_accepted_by_a_number_of_secondary_sources_including_[[Plants_of_the_World_Online]].'"`UNIQ--ref-00000016-QINU`"'_Linnaeus_initially_described_four_species_with_''P._hieracioides'',_''P._echioides'',_''P._pyrenaica''_and_''P._asplenioides''.'"`UNIQ--ref-00000017-QINU`"'_In_1913,_Britton_and_Brown_proposed_''P._asplenioides''_as_the_type_species_for_the_genus.'"`UNIQ--ref-00000018-QINU`"'_Subsequently,_in_1930,_Hitchcock_and_Green_alternatively_proposed_''P._hieracioides''_as_the_type_species.'"`UNIQ--ref-00000019-QINU`"'_The_Hitchcoc|[21]]]

M. aspera has also been determined to be a synonym of P. rhagadioloides.[20]311.
