Calydorea is a small genus of perennial, herbaceous and bulbous plants in the family Iridaceae native to Mexico and South America.[http://apps.kew.org/wcsp/namedetail.do?name_id=327000 Kew World Checklist of Selected Plant Families] The plants in the genus are small with tunicated bulbs. The flowers are light blue, violet, white, or yellow, depending on the species, of which there are around twenty. Taxonomists considered that the already known genera Salpingostylis (endemic from Florida), Cardiostigma (from Mexico), Catila (from Brazil) and Itysa (from Venezuela) are not enough different from each other to justify their taxonomic segregation and, for this reason, all of them are now included in Calydorea.Goldblatt, P. & J.E. Henrich. 1991. Calydorea Herbert (Iridaceae-Tigridieae): Notes on this New World genus and reduction to synonymy of Salpingostylis, Cardiostigma, Itysa and Catila. Annals of the Missouri Botanical Garden 78: 504-511

The genus name is derived from the Greek words caly, meaning "sheathed", and dorea, meaning "spear".{{cite book |author1=Manning, John |author2=Goldblatt, Peter |title=The Iris Family: Natural History & Classification |publisher=Timber Press |location=Portland, Oregon|pages=233–35 |year=2008|isbn=978-0-88192-897-6}} C. xiphioides lends its common name, tahay, to the exoplanet Gliese 367 b.{{cite web |url=https://www.nameexoworlds.iau.org/2022approved-names |title=2022 Approved Names |website=nameexoworlds.iau.org |publisher=IAU |access-date=7 June 2023}}
