Ida, synonym Sudamerlycaste, is a genus of flowering plants in the family Orchidaceae.

From 2001 onwards, species in Lycaste that were endemic to South America and the Caribbean Islands were placed into a new genus.

As a result of this change, most of the species previously found in the Lycaste section Fimbriatae were moved to a new genus.

[4] Separately, Fredy Archila Morales published Sudamerlycaste, but without a Latin description, so the name was illegitimate.

Archila corrected this in a publication that has been dated to 2009,[5] but included the type of Ryan and Oakeley's earlier published Ida, so this was the name that should have been used.
