The names of nothogenera for tetrageneric hybrids are formed "from a personal name to which is added the termination ‑ara" (article H.6.3, International Code of Nomenclature). The suffix -ara to denote a multigeneric hybrid was introduced by the Orchid Committee of the Royal Horticultural Society for orchid hybrids in 1909 and has been included in the International Code of Nomenclature since 1952.
Presumably named for Australian epicactus hybridizer Joyce Carr (-2001). ×Carrara Garay & H.R.Sweet (1966) is an orchid nothogenus.
