Originally published in Trudy Imperatorskago S.-Peterburgskago Botaniceskago Sada. Acta horti petropolitani (abbr. Trudy Imp. S.-Peterburgsk. Bot. Sada OR Act. Hort. Petrop.) 17: 142. 1898. Published by Johannes Christoph Klinge (1851-1902) near the end of his career.
McVaugh (1985) writes that this species is found in western Mexico "on trees and rocks, ravines in rather humid oak-pine forest or barranca forest, 900-1500m on the Pacific slope, flowering July-September."
Barney Greer writes that S. intermedia "is probably the Mexican Stanhopea most rarely seen in our collections. It has been notably misidentified as S. wardii var. flava, but is separated clearly from S. wardii... by its three-lobed epichile, the small sac on the base of the hypochile and its clear, unspotted yellow-to-orange colouration. Also, as Dr. Dodson pointed out in his 1963 AOS Bulletin study of the Mexican Stanhopeas, S. intermedia is extremely unusual in being recognizably different from other Stanhopea plants because of its "slightly flattened, nearly smooth pseudobulbs, short petiole and yellowish-green leaves."
Listed for Pihuamo, Mexico, in "Ordenamiento Ecologico Territorial de Estado de Jalisco: Grupo Flora" (Jan. 1998).
Synonym: Stanhopea wardii var. flava.
