A reappraisal ofPelargonium sect.Ligularia (Geraniaceae)

  • Focke Albers
  • Mary Gibby
  • Mathilde Austmann


A study of 33 species ofPelargonium sect.Ligularia reveals four basic chromosome numbers, x = 8, 9, 10, and 11, and variation in chromosome size. From evidence of karyology and hybridization attempts, proposals are made to divide the section into smaller groups and to transfer some species to other sections.
