In Greek, κρίνο (=crinum) can certainly be used for the Amaryllid it is applied to in Scientific nomenclature. But in fact, it is used for most any small wild petaloid monocot. It is applied to irises and lilies as often as Amaryllids...so stretching it to apply to a crocus (even though that is a common Greek name today as well) is not unreasonable! I find it charming that the song that propelled Nana Mouskouri to superstardom in Greece, namely Nikos Gatsos classic "Athina" sums up the vast, sprawling metropolis of Athens as a "small blue irid": surely, no city has had a more charming or lyrical song written about it than this classic of modern Greek lyric poetry.
