Calydorea

Calydorea is a small genus of perennial, herbaceous and bulbous plants in the iris family (Iridaceae) which is distributed in America. The genus includes small plants, with tunicated bulbs, perfect flowers with three free stamens and tepals in white, yellow, violet or light blue colors, depending on the species. Calydorea includes about 20 species which are distributed from Southern United States to Chile and Argentina. 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.[2]

The genus name is derived from the Greek words caly, meaning "sheathed", and dorea, meaning "spear".[3]
