The nothogenus ×Cyathidaria is established to accommodate various natural hybrids between species of Cyathea and Cnemidaria, all characterised by abortive spores and morphologically intermediate between their respective parent species. ×Cyathidaria acunae, the natural hybrid between Cnemidaria horrida and Cyathea aspera is a newly described nothospecies from Cuba. Four new combinations in ×Cyathidaria are made.
