The Chilean Plants Cytogenetic Database is a comprehensive catalogue of cytogenetic information on Chilean flora. It currently includes data on chromosome numbers (2n), karyotype morphology, nuclear DNA content, banding patterns, and/or FISH for 604 species—95 Bryophyta, 25 Pteridophyta, four Pinophyta, and 480 Magnoliophyta—compiled from 150 assembled references. The database is continuously updated as new species and data become available.
