• Etymology: "From the Latin 'quadri', four, 'fariam', in rows or ranks; in reference to the labellum calli which are usually in four rows."
• Text: "Although this species frequently grows large the epithet 'gigantea' was considered inappropriate at species rank, especially in view of the large dimensions attained by many of the spider orchids."
