We have published a new ChromoDB Cytogenetic Synthesis devoted to Acanthophyllum C.A.Mey. (Caryophyllaceae).
The study critically reviews published chromosome data and reconciles historical records with the current Plants of the World Online (POWO) taxonomy. Chromosome information was located for 20 of the 82 currently accepted species (24.4%), revealing a genus still markedly under-sampled cytogenetically.
The synthesis confirms x = 15 as the predominant basic chromosome number, with diploid, tetraploid and hexaploid levels, while also reassessing the more restricted x = 14 lineage. Particular attention is given to B chromosomes, historical taxonomic re-identifications, contradictory records and several errors detected through direct examination of the primary literature.
The complete synthesis and its three supporting datasets are openly available on Zenodo:
