I am not a botanist or familiar with the botanical Code ( https://www.iapt-taxon.org/nomen/pages/intro/dates.html), but would like to establish which is the correct spelling of this species of oak found in western Cuba. The OD clearly spells it sagraeana ( https://archive.org/details/cihm_40072/page/n61/mode/2up), but modern Cuban authorities appear to spell it sagrana, while a brief internet search seems to throw up virtually equal numbers of both spellings (wikipedia, for example, spells it sagraeana). Any reason in the botanical Code why the original spelling has been abandoned in favour of sagrana. Thank you!
