We elucidate the evolutionary history of a controversial group of seven genera of cacti (Coryphantha, Escobaria, Mammillaria, Mammilloydia, Neolloydia, Ortegocactus and Pelecyphora).
Genus Oncidium Sw. is widely regarded as a polyphiletic, and the taxonomic boundaries between him and such genera as Odontoglossum Kunth. or Miltonia Lindley remain blurred. The aim of the study was t
